    Implementering och resultat av Göteborgsmodellen för mindre matsvinn2020Report (Other academic)
    Abstract [en]

    The Gothenburg model for less food waste - a model forreducing food waste in municipal kitchensThe Swedish law states that all school children shall be served a nutritious, free schoollunch every day meaning that about 3 million meals are served per day in the municipalsector in Sweden. By developing efficient working models aimed for decreasing the foodwaste climate impact and costs can be significantly reduced.“The Gothenburg model for less food waste” is a practical tool describing simple andappropriate working routines aimed for reducing food waste in municipal kitchens. Thetool is designed to be used by the staff working in the kitchens. This report elucidatesdata and experiences from the implementation of “The Gothenburg model for less foodwaste”.Gothenburg City has a large meal organization with about 520 kitchens covering preschools,schools and elderly care settings. Through the “Gothenburg model for less foodwaste”, the City of Gothenburg reduced its food waste (serving and kitchen waste) in itskitchens by 50%, from about 30 g/serving to 15 g/serving, in two years, from January2017 to December 2018. At the end of the project, 95% of the kitchens measured theirfood waste. Together, these kitchens served over 80,000 lunches a day. Based on themeasurements in 2017–2018, serving waste accounted for about 80% of food waste,while 20% was kitchen waste.Based on the collected data on food waste targets for different categories of kitchenscould be formulated for serving and kitchen waste. The values suggested for schools were8 - 10 g/serving for production kitchens, 10-15 g/serving for reception kitchens and 30 -35 g/serving for serving kitchens. The corresponding values for pre-schools were 5 - 8g/serving for production kitchens, 10 - 15 g/serving for reception kitchens and 25 - 30g/serving for serving kitchens.The project has contributed to long-term effects by introducing a systematic approachfor reducing food waste in municipal kitchens. By  working according to the model, thekitchens have established procedures for reducing kitchen and serving waste as well asidentified structural problems that must be addressed in  the future for decreasing thefood waste further.Collected data for a time span up to 5 years  show that it takes time establish routines andlong-lasting changes. Generally, food waste levels decrease quite fast in the beginningdue to the easy wins and then level off gradually.

    Mapping potential location for bilberry picking with remote sensing, local field data andphone application2023Conference paper (Other academic)
    Abstract [en]

    The aim of the study was to create a practical method for identifying potential locations for bilberry picking with help of remote sensing, local field data and phone application to support the development of the local berry value chain. Local field data w as collected 2021 and 2022 and consisted 503 and 525 plots from a study area of circa 25x45km in Västerbotten, Sweden. The potential for bilberry production was evaluated by measuring the shrub cover and amount of raw berries. Wall to wall remote sensing d ata included a Sentinel 2 image from same summer, airborne laser scanning data from 2020 and other map products. We created classification models for bilberry shrub and yield using both logistic regression (2 classes) and ordinal regression (3 classes) mod els using 2021 data, and validated and calibrated models with 2022 data. Predictor variables consisted of spectral metrics from satellite data; structural metrics from laser data; existing raster maps of tree species, stand attributes, site index, soil moi sture and land use classes. The 2 class models performed better than three class models, delivering the AUC 0.73, overall accuracy 0.83 and kappa value 0.51 for best bilberry shrub model and 0.75, 0.77 and 0.50 respectively for best bilberry yield model. T he best models included both laser based structural metrics describing e.g canopy closure and spectral metrics, but also e.g. volume of pine, soil moisture and site index were found significant predictor variables. Calibration of the models improved annual predictions and the validation of the 2021 raster maps with 2022 data produced similar AUC, OA, and kappa values for bilberry yield (0.73, 0.74 and 0.46), but lower for bilberry shrub (0.61, 0.68 and 0.24). A dedicated phone application was developed duri ng the project, which was used both for collecting the field data and for presenting the potential locations of berry yields. Local berry maps can help berry pickers easier to find the berries in forest landscape and therefore support local berry value cha in. This study is part of the FAIRCHAIN project, which has received funding from the European Union’s funding programme H2020 research and innovation programme under grand agreement 101000723.

    Food Waste Drivers in Europe, from Identification to Possible Interventions2017In: Sustainability, ISSN 2071-1050, Vol. 9, article id 37Article in journal (Refereed)
    Abstract [en]

    The growing volumes of food globally lost or wasted and implications for food security and sustainability have raised the concern of researchers, governments, international organizations and grass-root movements. Much research and experiences investigating food waste causes and drivers focus on one specific segment of the food supply chain and limit the analysis to the situation of one or few countries, while the few studies of wider geographical scope also target other relevant and diversified objectives (e.g., food waste definition, quantification, environmental and economic impacts, and recommendations for interventions). This study, carried out by a network of European institutions involved in research and initiatives against food waste, focuses on the analysis of a broad area, Europe, through a wide and systematic literature review and consultation with stakeholders in international focus groups. The food supply chain was divided into seven segments and three main contexts were defined for the examination of food waste sources: Technological, Institutional (related to organisational factors, i.e., business management, economy, legislation, and policy), and Social (related to consumers’ behaviours and lifestyles). Results suggest a wide and multifaceted problem, interconnected across all stages of the food supply chain, from primary production, to final consumption. Within each context, the identified drivers have been grouped according to the possibilities and the type of interventions for food waste reduction. A final cross-contextual prioritization distinguished food waste sources related to (A) inherent characteristics of food; (B) social and economic factors; (C) individual non-readily changeable behaviours; (D) other priorities targeted by private and public stakeholders; (E) diversified factors, such as mismanagement, inefficient legislation, lack of awareness or information; and sub-optimal use of available technologies, which could be more promptly changed. Such diversification of causes calls for specific monitoring systems, targeted policy measures, and actions of individual stakeholders at each stage of the food supply chain.

    Food waste accounting methodologies: Challenges, opportunities, and further advancements2019In: Global Food Security, ISSN 2211-9124, Vol. 20, p. 93-100Article in journal (Refereed)
    Abstract [en]

    About one third of the food produced globally is wasted along the food chain, representing a burden for the environment and an inefficiency of the food system. Tackling food waste is a priority on the global political agenda to guarantee food security. Defining a methodology for food waste quantification is key to monitoring progress towards the achievement of reduction targets. This paper summarises the outcomes of a workshop on food waste accounting co-organised by the European Commission's Joint Research Centre and Directorate-General on Health and Food Safety with the aim of stimulating harmonisation of methodologies, identifying challenges, opportunities, and further advancement for food waste accounting. The paper presents methodological aspects, e.g. system boundaries, reliability of data, accounting of water flows, to ensure better support to food waste policy design and interventions. It addresses all the actors of the food supply chain, governments, and research institutions. © 2019 The Authors

    Generic strategy LCA and LCC: Guidance for LCA and LCC focused on prevention, valorisation and treatment of side flows from the food supply chain2017Report (Other academic)
    Abstract [en]

    Urged by the importance of resource efficiency and circular economy agenda of EU and national policy makers, many stakeholders are seeking alternatives for current surplus food or side flows within the food supply chain. Any new valorisation route for side flows (i.e. not the main product) will be associated with impacts (monetary and environmental). To allow informed decision making at all levels, from individual stakeholder to policy level, robust, consistent and science based approaches are required. The EU H2020 funded project REFRESH (Resource Efficient Food and dRink for the Entire Supply cHain) aims to contribute to food waste reduction throughout the food supply chain, and evaluate the environmental impacts and life cycle costs.

    Life Cycle Analysis (LCA) and Life Cycle Costing (LCC) are well documented and generic approaches for assessing the environmental and cost dimensions of a system. Both LCA and LCC are characterised by allowing for a large flexibility in system scoping. To allow for comparison between different options consistent approaches are required. Furthermore, there is a need to bridge the gap between assessors who might have a deep knowledge of the systems they are assessing, but are not in depth method experts on LCA or LCC. Highlighting challenging methodological aspects and encouraging the practitioner to ask the most relevant questions contributes to a better scoping practice of LCA and LCCs.

    The objective of this study was to develop a consistent approach, combining LCA and LCA specifically to assess impacts of prevention of resource inefficiencies, valorisation routes and waste handling in the food supply chain. The recommendations build on existing standards and state-of-the-art LCA/LCC research, and provide guidance on how to overcome specific methodological challenges. They focus particularly on the goal and scope stage of an LCA and Environmental LCC and on side flows from the food supply chain.

    To categorise systems in order to be assessed, the concept of “REFRESH situations” (RS) has been developed (De Mena et al., 2016; Unger et al., 2016). The four REFRESH situations (RS) are: Prevention of side flow (RS 1), side flow valorisation (RS 2), valorisation as part of waste management (RS 3), and end-of-life treatment (RS 4). The REFRESH situations can take place at any point/process in the life cycle, within the remit of any stakeholder (including consumers) and are independent of the perspective taken, i.e. of the producer of side stream or the receiver. For each REFRESH situation, specific recommendations on setting of system boundary, functional unit(s) and handling of multi-functionality in relation to the stated problem are provided (beside some other aspects). The importance to differentiate between attributional and consequential approaches is discussed in detail. This consistent approach contributes towards more harmonised use of LCA and LCC for informed decision for handling side flows in the food supply chain.

    The focus of the specific recommendations given in this report is primarily on change-oriented studies on interventions for side flows since foot print studies are to a higher degree covered in existing frameworks such as the ILCD-handbook and the PEF framework under development.

    A combined framework for the life cycle assessment and costing of food waste prevention and valorization: an application to school canteens2020In: Agricultural and Food Economics, ISSN 2193-7532, Vol. 8, no 1, article id 2Article in journal (Refereed)
    Abstract [en]

    About one third of global edible food is lost or wasted along the supply chain, causing the wastage of embedded natural and economic resources. Life cycle methodologies can be applied to identify sustainable and viable prevention and valorization routes needed to prevent such inefficiencies. However, no systemic approach has been developed so far to guide practitioners and stakeholders. Specifically, the goal and scoping phase (e.g. problem assessed or system function) can be characterized by a large flexibility, and the comparability between food waste scenarios could be not ensured. Within the Horizon2020 project Resource Efficient Food and dRink for the Entire Supply cHain, this study aimed to provide practitioners with guidance on how to combine life cycle assessment and environmental life cycle costing in the context of food waste. Recent literature was reviewed to identify relevant methodological aspects, possible commonly adopted approaches, main differences among studies and standards and protocols, main challenges, and knowledge gaps. Basing on this review, an analytical framework with a set of recommendations was developed encompassing different assessment situations. The framework intends to provide a step by step guidance for food waste practitioners, and it is composed of a preliminary section on study purpose definition, three decision trees—respectively on assessment situation(s), costing approach, and type of study (footprint vs. intervention)—and two sets of recommendations. Recommendations can be applied to all levels of the food waste hierarchy, stating a generic order of preference for handling food chain side flows. This consistent and integrated life cycle approach should ensure a better understanding of the impact of specific interventions, thus supporting informed private and public decision making and promoting the design of sustainable and cost-efficient interventions and a more efficient food supply chains. © 2020, The Author(s).

    Plant based meat alternative, from cradle to company-gate: A case study uncovering the environmental impact of the Swedish pea protein value chain2023In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 418, article id 138173Article in journal (Refereed)
    Abstract [en]

    Dry-fractioned pea protein concentrate can be moulded into meat-analogue products, and understanding the environmental impact and hot spots of this expanding industry segment could pave the road to broader adoption of these protein sources. Hence, this research measures the environmental performance of a green pea protein supply chain in southern Sweden that processes pea protein concentrate into pea protein sausages. A cradle-to-factory-gate life-cycle assessment was performed. 1 kg of pea protein concentrate at 46% and 1 kg of pea protein sausages were chosen as functional units, while ReCiPe 2016 v1.1 Midpoint E was utilized to calculate 18 impact categories. Economic allocation was applied to pea protein processing, and mass allocation to sausage production, using 2021/22 data from Swedish companies. For 1 kg of pea protein concentrate of 46%, cultivation contributes to 41–99% of the total impact considering all 18 impact categories, while processing 1–59%. The climate impact was 1.91 kg CO2eq/kg pea protein concentrate (1.54 from the cultivation step and 0.37 from the processing step). For 1 kg of pea protein sausages, cultivation and sausage production contributed together between 32% and 78% to the total impacts. The climate impact was 1.0 kg CO2eq/kg sausage. Comparing the climate impacts of sausage ingredients, rapeseed oil and spices contributed significantly. For the sausage production stage, electricity and natural gas contributed the most. The results for climate impact are in the same range as for similar plant-based products, although the range reported in literature is wide. Green pea cultivation, sausage production and ingredients contributed all significantly. The results highlight the need to address the choice of ingredients when formulating the final product. The choice of allocation method had a significant impact on the results. Mass allocation resulted in 6 times lower impacts for the pea protein concentrate compared to economic allocation. © 2023 The Authors

    CFD simulation and ERT visualization of the displacement of yoghurt by water on industrial scale2007In: Journal of Food Engineering, ISSN 0260-8774, E-ISSN 1873-5770, Vol. 80, no 1, p. 166-175Article in journal (Refereed)
    Abstract [en]

    The rinsing step, in which yoghurt is displaced by water, was monitored in a dairy plant using electrical resistance tomography (ERT), with a new hygienic design of the ERT sensors. The same displacement situation was simulated using computational fluid dynamics (CFD) and showed good agreement with the ERT measurements. CFD was also used to study how different properties, such as flow velocity, wall slip and the rheological properties of the yoghurt, could change the effectiveness of rinsing. © 2006 Elsevier Ltd.

    Plug flow of yoghurt in piping as determined by cross-correlated dual-plane electrical resistance tomography2006In: Journal of Food Engineering, ISSN 0260-8774, E-ISSN 1873-5770, Vol. 76, no 2, p. 163-168Article in journal (Refereed)
    Abstract [en]

    Cross-correlation of electrical resistance tomography (ERT) was used to determine the velocity profile of yoghurt in a pipe of industrial dimensions. In viscometry, at shear rates higher than 10 s-1, the yoghurt followed the power law model with a K-value of 3.7 Pa sn and an n-value of 0.37. In pipe flow, however, within the tested mean velocity range of 0.05-0.25 m s-1, the yoghurt appeared to flow as a plug. The local velocity was constant from the centreline to within 3 mm of the tube wall, which corresponds to the resolution of the ERT method. © 2005 Elsevier Ltd. All rights reserved.

    The electrical conductivity of milk: The effect of dilution and temperature2005In: International journal of food properties, ISSN 1094-2912, E-ISSN 1532-2386, Vol. 8, no 1, p. 15-22Article in journal (Refereed)
    Abstract [en]

    The electrical conductivity of milk at various dilutions was measured at different temperatures from 2 to 70°C. The results showed that dilution has only a small influence on the temperature dependence of conductivity. A simple power-law model predicts that the conductivity is proportional to the milk concentration to the power of 0.84 and a two-term model describes the temperature dependency. The overall model has a standard deviation of 0.0067 mS cm-1, which corresponds approximately to 0.1% milk at 2°C and 0.07% milk at 70°C. It was further shown that for less than about 25% milk in water Kohlrausch's law and the Debye-Hückel-Onsager theory can be used to describe the relationship between the concentration, temperature, and conductivity using a representative limiting molar conductivity of milk ions of 75 mS cm2 mol-1.

    Sensor fusion as a tool to monitor dynamic dairy processes2006In: Journal of Food Engineering, ISSN 0260-8774, E-ISSN 1873-5770, Vol. 76, no 2, p. 154-162Article in journal (Refereed)
    Abstract [en]

    A system for monitoring milk and fat concentration in a dynamic milk/water system by fusing information from several sensors was investigated. Standard instrumentation for food production was used, the sensors were a conductivity meter, a density meter and an optical instrument used to measure backscattered light. The system was applied to a dynamic mixing situation. Prediction error did not exceed 2% in the milk concentration and 0.1% fat in the total fat concentration. The applicability of the sensor fusion approach in field conditions was demonstrated by mounting the sensors in a dairy plant and monitoring the start-up of a pasteurizer. © 2005 Elsevier Ltd.

    Challenges and Experiences2013In: Transparency for Sustainability in the Food Chain: Challenges and Research Needs-EFFoST Critical Reviews #2, Elsevier Inc. , 2013, p. 21-65Chapter in book (Other academic)
    Abstract [en]

    In the identification of transparency challenges evolving from a discrepancy between needs, state-of-the-art, and experiences that will be discussed, the Strategic Research Agenda (SRA) has utilized a broad range of approaches, including literature analysis, best practice analysis, chain analysis, work group discussions, expert discussions, surveys, web consultations, and simulation studies to reach results that serve the objectives.In this chapter, the focus is on the layer approach, the integrated view follows thereafter. The layer approach distinguishes between. a.upper levels linked to the recipients of transparency andb.lower levels linked to the actors in the food value chain and their production and distribution processes.The different layers identify different communication needs. The lowest level provides the ". infrastructure" for data communication. It is closely related to information technology and the identification of the path that a product takes from production to consumption. This is linked to the tracking and tracing functionality which makes it feasible to communicate additional information as "backpack" on the tracking and tracing information base.The next layer serves the collection of information about the various domains (food safety, food quality, chain integrity) of interest. This layer represents the classical information collection and communication approach. The third layer involves the transformation of information into signals or further to simple-to-understand messages like "this food is safe" which serve the transparency needs of the various stakeholders (consumers, enterprises, and policy) depending on the situation they are in (scenario).

    Early phase design tool for non-LCA experts: Integrating environmental assessment in the development of novel processing technology in food industry2017Conference paper (Other academic)
    Abstract [en]

    The Life Cycle Assessment methodology often applies a product perspective but can be used to assess novel production technologies by comparing novel products with a baseline product, as long as the functional unit of the product is considered to be the same. There is increasing environmental concerns in society and pressures on industry to take into account their impact on the environment. Tools are available for this, but not tools adapted to specific industry needs. The reasons to use LCA are foremost to guide the development towards the most sustainable solutions and to evaluate the market potential from an environmental perspective. Challenges arise when applying LCA in early development stages, e.g. getting access to recent development data, to increase commitment and incentives to take early LCA results into consideration, to present results in an attractive way etc. LCA calculations must also keep up with the sometimes rapid development. In order to meet these challenges interactive report software have been introduced to industrial partners (non-LCA experts) in an EU project called FutureFood (Grant agreement no: 635759). The project goal is to develop a new processing technology for foods (CO2 drying). In order to meet the LCA related challenges a platform has been used that is developed by PRé Consultants (Pre, 2016?), called Share and Collect. It allows LCA experts to develop tools for non-experts so that users are able to alter parameters in the LCA model and assess the result of the changes. It is done by providing the industrial partners with an intuitive web based graphical user interface (GUI). When a user changes input data in the GUI, parameter values also change in the model, an LCA calculation engine runs the model and the GUI presents the corresponding results. In the project a tool for assessing the processing technology has been developed and the industrial partners  are provided rights to access the tools and create ‘what if’ scenarios. Examples of changes are change of electricity production, transport distances, transport types or modes, raw material source, packaging, production resource or energy efficiency etc. The tool has been evaluated by the non-LCA expert industrial partners, and the first review results show that it is user friendly, visually appealing and interesting in its interactive way because of the instant feedback of results. Tailored models such as the ones developed in the project have the potential to support knowledge based decisions in innovation projects in companies.

    Alternative protocols for the production of more sustainable agar-based extracts from Gelidium sesquipedale2021In: Algal Research, ISSN 2211-9264, Vol. 55, article id 102254Article in journal (Refereed)
    Abstract [en]

    Agar-based extracts from Gelidium sesquipedale were obtained by applying a conventional hot water treatment and alternative ultrasound- and microwave-assisted methods, with and without the application of an alkaline pre-treatment. The alkaline pre-treatment produced refined extracts with higher purity; however, extraction yields increased from 2–5% to 7–19% by omitting this step. In particular, the ultrasound-assisted extraction allowed reducing 4-fold the extraction time, while keeping constant or even increasing the yield (up to 19% for the 1 h extraction) with respect to the conventional protocol. Interestingly, the presence of proteins and polyphenols conferred the semi-refined extracts a relatively high antioxidant capacity (19–24 μmol TE/g extract). The refined extract produced by the standard protocol formed the strongest hydrogels (>1000 g/cm2). On the other hand, the semi-refined extracts produced by the alternative protocols formed slightly stronger hydrogels (337–438 g/cm2) than the refined counterparts (224–311 g/cm2), due to their greater molecular weights of the former ones. LCA assessment showed lower global warming potential for the semi-refined extracts, especially the ultrasound-assisted extraction, hence highlighting the potential of this method to produce more sustainable agar-based extracts for food-related applications.

    Performance, energy and cost evaluation of a nanofiltration plant operated at elevated temperatures2008In: Separation and Purification Technology, ISSN 1383-5866, E-ISSN 1873-3794, Vol. 60, no 1, p. 36-45Article in journal (Refereed)
    Abstract [en]

    The influence of temperature on cost and energy consumption during nanofiltration has been evaluated. The effect of temperature on pressure drop, fouling, concentration polarisation and changes in the membrane performance were evaluated experimentally and theoretically. Nanofiltration experiments using pure solutions and wastewater from the meat industry were performed at 25 and 55 °C with an Alfa Laval NFT-50 nanofiltration membrane. The results showed that the flux was slightly higher during wastewater concentration at 55 than at 25 °C. The difference was smaller than expected and is explained by both fouling and changes in the membrane performance due to the combined effects of pH and temperature. The concentration polarisation was found to be less at the higher temperature, as predicted by theory. However, this effect was small in comparison to the effect of temperature on fouling and the membrane performance. The influence of cleaning procedure on flux and retention was very dependent on the processing temperature due to time- and temperature-dependent changes in the membrane performance. Nanofiltration plants designed to run at 25 and 55 °C were dimensioned based on the results of the pilot study. Nanofiltration at 55 °C was found to be slightly better with respect to the investment cost. The energy required for pumping was lower at 55 °C. However, the energy required for heating is high and processing at 55 °C is only advantageous if the feed is already warm, if there is excess heat in the factory, or if the heat can be recycled. © 2007 Elsevier B.V.

    Influence of temperature and cleaning on aromatic and semi-aromatic polyamide thin-film composite NF and RO membranes2008In: Separation and Purification Technology, ISSN 1383-5866, E-ISSN 1873-3794, Vol. 62, no 3, p. 717-726Article in journal (Refereed)
    Abstract [en]

    Although cleaning removes fouling, it may change the properties of membranes and consequently influence their performance. We have evaluated the combined effect of acidic/alkaline cleaning and temperature on the performance of two aromatic membranes, one a reverse osmosis membrane (HR98PP) and the other a nanofiltration membrane (NF90), two semi-aromatic polypiperazine membranes (NF200, NFT-50) and a Desal-5DK nanofiltration membrane. At the retention minimum of each membrane, the KCl retention and the water permeability were in the order: NFT-50 < NF200 < Desal-5DK < NF90 < HR98PP and HR98PP < NF90 < NF200 < Desal-5DK < NFT-50, respectively. After nanofiltration at elevated temperatures acidic and alkaline cleaning increased the water permeability and decreased the retention of the Desal-5DK membrane. Similar behaviour was observed after acidic cleaning of the aromatic polyamide membranes and with alkaline cleaning of the semi-aromatic polyamide (polypiperazine) membranes. Increased hysteresis was seen in the membrane performance with increasing temperature. The hysteresis behaviour was dependent on the cleaning procedure and could be related to swelling and shrinkage of the active polyamide layer. At 40 °C the reverse osmosis membrane (HR98PP) showed the same performance as the NF90 nanofiltration membrane at 20 °C. © 2008 Elsevier B.V. All rights reserved.

    The influence of different kinds of pre-treatment on the performance of a polyamide nanofiltration membrane2006In: Desalination, ISSN 0011-9164, E-ISSN 1873-4464, Vol. 195, no 42007, p. 160-168Article in journal (Refereed)
    Abstract [en]

    Although pre-treatment of membranes is often used to ensure the reliability of experimental data, it also has the potential to improve many aspects of membrane performance. This study investigates the influence of chemical pre-treatment and wetting on membrane flux and retention. The results show that chemical pre-treatment, with either a phosphate buffer or alkaline cleaning agents, enhances the flux and lowers the retention. Wetting at 40°C after membrane cleaning increased the flux and retention, whereas wetting at 50°C decreased the flux and increased the retention. No effect of pre-treatment with NaOH, at pH 9.8 or 10.4, was observed. The influence of NaCl on flux and surface contact angle was also evaluated, and pre-treatment with 0.20 M NaCl(aq) was shown to increase the flux but to have no effect on surface contact angle. The origin of the positive effect of chemical pre-treatment on membrane flux appears to lie in the ion-membrane interactions within the membrane, where time and temperature are of importance. This would explain our finding that some of the positive effects of cleaning agents and NaCl on membrane flux are quickly lost after increasing the processing temperature during pure water flux measurements. © 2006 Elsevier B.V.

    The influence of pH, salt and temperature on nanofiltration performance2008In: Journal of Membrane Science, ISSN 0376-7388, E-ISSN 1873-3123, Vol. 312, no 42006, p. 97-106Article in journal (Refereed)
    Abstract [en]

    The influence of pH, KCl and temperature on the performance of an Alfa Laval NFT-50 nanofiltration membrane was evaluated by glucose and KCl retention measurements at constant flux. It was found that at constant temperature an increase in pH in the absence of KCl reduced the water permeability, and this was correlated to the electroviscous effect. The selectivity decreased with increasing KCl concentration and the decrease became more evident with increasing pH. The decrease in selectivity could be related to membrane swelling, and it appears that pH had no effect on swelling other than enhancing the effect of KCl. The influence of KCl and pH on membrane performance was evaluated as a function of temperature after reaching steady state at 50 °C. The degree of swelling was higher at 50 °C than at 20 °C, due to an increase in polymer flexibility with increasing temperature. The decrease in selectivity with increasing temperature was less for KCl than for glucose, showing that the charge effect was influenced less by temperature than diffusion through the membrane. © 2008 Elsevier B.V.

    The influence of sodium chloride on mass transfer in a polyamide nanofiltration membrane at elevated temperatures2006In: Journal of Membrane Science, ISSN 0376-7388, E-ISSN 1873-3123, Vol. 280, no 42006, p. 928-936Article in journal (Refereed)
    Abstract [en]

    The influence of temperature (20-50 °C) and NaCl on mass transfer of pure water and glucose solution (0.0055 M) using an Alfa Laval NFT-50 nanofiltration membrane has been investigated. Addition of 0.017 M NaCl(aq) increased the membrane permeability in comparison to measurements with pure water. Performing cyclic temperature variations using a membrane pre-treated with 0.20 M NaCl(aq) caused the membrane permeability to decrease for each time a new maximum temperature was reached. After NaCl pre-treatment, the relative flux decline measured over 4 h was found to be greater for glucose than for water, and the rate of the flux decline for both water and glucose increased with temperature (20-50 °C). The permeability was found to be unaffected by the pressure if the membrane had previously been rinsed at a lower pressure but at a higher temperature. Changes in permeability due to the presence of NaCl could be related to interactions in the active polymer layer of the membrane. MgCl2 pre-treatment influenced the membrane permeability less that NaCl pre-treatment. © 2006 Elsevier B.V. All rights reserved.

    Assessing sustainability of innovative solutions for wild berry picking in Sweden2023Conference paper (Other academic)
    Abstract [en]

    A substantial quantity of berries is grown in Sweden, estimated at more than 550 000 tons every year. Intriguingly, only a fraction of this amount (some 2 5%) finds practical utilization. Historically, the low utilization rate can be attributed to a scarcity of harvesting personnel, challenges in accessing the harvesting sites, and logistical complexities. Even with the current berry picking value chain, which is mostly operated by seasonal Thai pickers, numerou s challenges persist. The workers’ work and life conditions are not satisfactory, and efficiency is low, making up a value chain that is far from sustainable. In an attempt for more efficient and sustainable chains, some innovative solutions are practiced in a European innovation project, FAIRCHAIN. These innovative solutions include (i) developing an app to track berries and spot more probable places to find berries in real time, and (ii) cleaning and processing the berries locally into products like jam o r use them as an ingredient in other products (e.g., dairy products) in different scales. We, however, regardless of the scale and prospectives of the innovations, put together a model to assess how sustainable these innovations are compared to the current value chains. Significance of such assessments in helping decision making and designing new value chains while considering different aspects of sustainability is clear. In pursuit of this objective, we have formulated a comprehensive framework tailored to evaluate the sustainability of the proposed innovations within the context of Multi Criteria Decision Analysis (MCDA). To establish the foundation of this framework, we selected 18 important sustainability indicators for potentially shaping the sustainability outcomes of various innovative solutions, covering the three foundational pillars of sustainability: environmental considerations, social responsibility, and economi c viability. These indicators are Capacity development , Fair contracts and fair pricing , Human safety and health , Collective bargaining , Food sovereignty , Labor rights and Equity , Quality of life , Food quality , Local procurement , Local employment , Stability of market , Product information , Profitability , Stability of production , Land use , Energy use , Biodiversity , and Atmospheric impacts . Leveraging the Analytical Hierarchy Process (AHP), we systematically assigned relative weights to these indicators, foste ring a nuanced evaluation process. The preliminary results indicate that social indicators (such as Quality of life and Capacity development ) and economic ones (such as Stability of production and Local employment ) gain the highest It is worth noting that the entirety of data to feed this model was gained after multiple rigorous sessions of discussion and weighting by the informed project partners to reach ultimate consensus. This is ongoing research and here we rely on showcasing the framework to highlight its capabilities and strengths and discuss its limitations. Insights found in such inclusive holistic assessment hold significant value for decision makers who need to see t he big picture before intervention decisions such as small and large scale innovations in short and long term.

    Predicting the displacement of Yoghurt by water in a pipe using CFD2007In: Chemical Engineering & Technology, ISSN 0930-7516, E-ISSN 1521-4125, Vol. 30, no 7, p. 844-853Article in journal (Refereed)
    Abstract [en]

    A numerical scheme based on the volume of fluid (VOF) method for predicting the displacement of one liquid by another has been verified versus electrical resistance tomography (ERT) and ultrasonic velocity profile (UVP) measurements for the displacement of yoghurt by water. The scheme using the VOF method predicts the skewed phase distribution as measured using ERT and the global structure of the velocity profile as measured using UVP. The phase distribution using the VOF method was compared with the results using the species transport model which allows for mixing between the phases. The species transport model was found to be less suitable for predicting the displacement of yoghurt by water since the turbulence model was unable to accurately predict the turbulent viscosity in the mixing zone between yoghurt and water, which resulted in a too high rate of mixing. © 2007 Wiley-VCH Verlag GmbH & Co.

    An improved numerical method of calculating the striation thinning in static mixers2005In: Computers and Chemical Engineering, ISSN 0098-1354, E-ISSN 1873-4375, Vol. 30, no 2, p. 376-380Article in journal (Refereed)
    Abstract [en]

    An improved method of calculating the rate of striation thinning for laminar flow in a static mixer has been developed. The shapes of the objects studied are reconstructed using elliptic Fourier descriptors, allowing discrimination between true changes in shape and noise due to discretization errors. The method also allows one to choose the level of complexity in the objects to be reconstructed which faciliates optimization of the computations without loss of information. The evaluation of the rate of striation thinning is based on local velocities giving a result closely related to the volumetric flow in different regions of the static mixer. © 2005 Elsevier Ltd.

    Effects of geometry and flow rate on secondary flow and the mixing process in static mixers-a numerical study2006In: Chemical Engineering Science, ISSN 0009-2509, E-ISSN 1873-4405, Vol. 61, no 18, p. 6133-6141Article in journal (Refereed)
    Abstract [en]

    A method based on computational fluid dynamics (CFD) for the characterization of static mixers using the Z factor, helicity and the rate of striation thinning is presented. These measures were found to be well-suited for the characterization of static mixers as they reflect the pressure drop, the formation of secondary flow, i.e. vortices, and their effect on the mixing process. Two commercial static mixers, the Kenics KM and Lightnin Series 45, have been characterized. In the mixers investigated, secondary flow is formed in the flow at the element intersections and due to the curvature of the mixer elements. The intensity of the vortices is higher in the Lightnin than the Kenics mixer due to edges in the middle of the Lightnin mixer elements. The formation of vortices affects the Z factor by an increase in the power requirement, and the rate of striation thinning by an increase in the stretching of the striations. The formation of vortices was observed at a Reynolds number of 10 in both mixers with aspect ratios of 1.5. However, the intensity of the vortices was greater in the Lightnin than the Kenics mixer, which was observed in not only the magnitude of the helicity, but also the Z factor, rate of striation thinning and the distribution of striation thickness. The distribution in striation thickness is shifted towards thin striations as the flow rate is increased from below to above the Reynolds numbers of which vortices were first observed, but some striations still pass the mixer elements almost unaffected, which can be seen in the skewness of the distribution of the striation thickness, which shifts from being negative to positive. © 2006 Elsevier Ltd.

    Influence of viscosity ratio on the mixing process in a static mixer: Numerical study2008In: Industrial & Engineering Chemistry Research, ISSN 0888-5885, E-ISSN 1520-5045, Vol. 47, no 9, p. 3030-3036Article in journal (Refereed)
    Abstract [en]

    The mixing process in a Lightnin Series 45 static mixer, 40 mm in diameter, has been investigated using computational fluid dynamics and the volume of fluid (VOF) method, a method developed for immiscible fluids but here used for miscible. The mixing process was investigated for two liquids that had viscosities ranging from 0.003 to 51.2 Pa s, and the volumetric flow rate proportion between the liquids was varied between 1/1 and 4/1. The flow rate was 0.1 m/s, and two Reynolds numbers, 1 and 70, were investigated. The mixer performance was evaluated using the rate of striation thinning, and it was found that the greater the difference in viscosity the worse the mixer performance. This effect is due to the difference in elongation rate between the liquids, which exists until equilibrium in shear stress has been reached at the interface between the liquids. For higher Re numbers close to a point when secondary motions start to have significance for the rate of striation thinning, a lower viscosity of the added liquid results in an increase in mixing performance. It was further found that the VOF method can be used to model the mixing of dissimilar liquids in static mixers, but since the thickness of the striations decreases rapidly with the number of mixer elements, the VOF method is most suitable when investigating mixing processes over a small number of mixer elements. © 2008 American Chemical Society.

    Environmental assessment of the valorisation and recycling of selected food production side flows2020In: Resources, Conservation and Recycling, ISSN 0921-3449, E-ISSN 1879-0658, Vol. 161, article id 104921Article in journal (Refereed)
    Abstract [en]

    Residues from the food manufacturing industry require management options with the best overall environmental outcome. The identification of sustainable solutions depends however, on many influencing factors such as energy input, transport distance, and substituted product. This study shows the influence of the choice of substituted products on the overall greenhouse gas (GHG) emissions for three specific food side-flows and their treatment in the European Union: animal blood, apple pomace and brewers’ spent grain (BSG). In a direct comparison of possible treatment options, it is notable that the conversion to food ingredients (valorisation) does not always result in reduced environmental net impacts (GHG savings), which means that other options at lower levels of the waste hierarchy might be more beneficial to the environment. The further use of apple pomace or BSG for the production of food ingredients is only advantageous if the processing emissions are smaller than the emissions from the substituted products. The use of food side-flows as animal feed shows environmental advantages in all scenarios, as the use of conventional feed, such as soybean meal or hay, is reduced and so are the GHG emissions. The anaerobic digestion of food side-flows is associated with significant GHG emissions, but alternative energy also display a high GHG factor when based on fossil resources. The measuring of circularity in the food sector is a challenge in itself due to the complexity of renewable materials. This study shall help to understand the interwoven influences of certain parameters to the results. © 2020 The Author(s)

    Climate Impact of Plant-based Meat Analogues: A Review of Life Cycle Assessments2023In: Sustainable Production and Consumption, ISSN 2352-5509, Vol. 36, p. 328-337Article, review/survey (Refereed)
    Abstract [en]

    The transition towards more plant-based diets is identified as an important measure for limiting dietary climate impact. Plant-based meat analogues (PBMAs) have been proposed as a viable lower carbon alternative to meat, and its market is rapidly growing globally. However, knowledge about the climate impact of PBMAs in relation to other foods is currently limited due to the challenge of comparing life cycle assessments (LCAs) using different methods. The aim of this study was to review the climate impact of PBMAs based on LCAs published up to 2021. Original LCA data were recalculated to harmonize differences in method choices among studies and presented as the climate impact of final products at factory gate. The median climate impact of PBMAs was estimated at 1.7 kg CO2 eq./kg of product with a more than fourfold variation in impact (0.5–2.4 kg CO2 eq./kg product). Climate impact per protein content of the final product varied from 0.4 to 1.2 kg CO2 eq./100 g protein with a median impact of 0.8 kg CO2 eq./100 g protein. Cultivation of raw materials and manufacturing were identified to be responsible for a large proportion of GHG emissions up to factory gate. However, the assessment of climate impact in the production chain was challenged by the level of detail of data provided. A transparent reporting strategy regarding the specific stages in the supply chain, method choices and product information is recommended to facilitate identification of hot spots to target for improved climate performance of future PBMAs and to enable accurate comparisons between studies. It could further be concluded that current scientific knowledge on the climate impact of PBMAs is based on a limited number of LCAs that often rely on a combination of secondary data and collected data at production scale or from pilot-scale production facilities. Future LCAs of PBMAs would benefit from additional assessments of commercial production using region- and site-specific data. © 2023 The Authors

    Paths to a sustainable food sector: integrated design and LCA of future food supply chains: the case of pork production in Sweden2016In: The International Journal of Life Cycle Assessment, ISSN 0948-3349, E-ISSN 1614-7502, Vol. 21, no 5, p. 664-676Article in journal (Refereed)
    Abstract [en]

    Purpose: To describe a more sustainable food sector, a supply chain approach is needed. Changing a supply chain inevitably means that various attributes of the product and its system will change. This project assumed this challenge and delivered detailed descriptions, life cycle assessment (LCA) evaluations, and consequence assessments of the supply chains of six commodities, i.e., milk, cheese, beef, pork, chicken, and bread, from a Swedish region. This paper presents results for the pork supply chain. Methods: In the project setup, experts on production along supply chains designed three scenarios for environmentally improved systems. These scenarios, i.e., the ecosystem, plant nutrients, and climate scenarios, were intended to address different clusters of environmental goals. The next step was to challenge these scenarios by considering their possible consequences for products and systems from the food safety, sensory quality, animal welfare, consumer appreciation, and (for primary production only) cost perspectives. This led to changes in production system design to prevent negative consequences. The final supply chains were quantified using LCA and were again assessed from the three perspectives. Results and discussion: The scenario design approach worked well, thoroughly and credibly describing the production systems. Assessment of consequences bolstered the credibility and quality of the systems and results. The LCA of pig production and smoked ham identified large potentials for improvement by implementing available knowledge: global warming potential (GWP) could be reduced 21–54 % and marine eutrophication by 14–45 %. The main reason for these improvements was improved productivity (approaching the best producers’ current performance), though dedicated measures were also important, resulting in increased nitrogen efficiency, more varied crop rotations for crop production and better production management, and improved animal health and manure management for animal production. Reduced post-farm wastage contributed as did reduced emissions from fertilizer production. Conclusions: The working approach applied was successful in integrating LCA research with food system production expertise to deliver results relevant to supply chain decision-makers. The consequence assessments brought considerable value to the project, giving its results greater credibility. By introducing constraints in the form of “no negative consequences and no increased costs,” the work was “guided” so that the scenario design avoided being hampered by too many opportunities.

    Underlag till Färdplan för en väsentligt mer hållbar livsmedelskedja2019Report (Other academic)
    Abstract [sv]

    Syftet med rapporten är att skapa ett underlag för mer operativa, eller konkreta, hållbarhetsmål för aktörerna i livsmedelskedjan. Dessa mål ska i möjligaste mån vara kopplade till kvantifieringar av en hållbar nivå för resursförbrukning och miljöpåverkan globalt.

    Rapporten beskriver en process som startar med att identifiera de relevanta hållbarhetsaspekterna för livsmedelsystemet och baserat på litteratur kvantifiera dessa på global nivå, nedbrutet till en globalt hållbar nivå per capita. Som ett komplement till det globala användes också nationella källor för de miljömål som är av mer regional karaktär. Livsmedelssektorns hållbarhetsprestanda är en kombination av konsumtionsmönster och hur effektiva och hållbara produktionssystemen är. Då rapporten syftade till att ge underlag för konkreta mål för alla aktörer i systemet skapades två typer av mål, en typ som berör konsumtionsmönster och en typ som berör produktionskedjornas hållbarhetsprestanda. För att de totala hållbarhetsmålen ska nås måste både konsumtionen och produktionen förändras, och med hjälp av dessa två mål kan båda aspekterna hanteras i samma ramverk. Om produktionssystemen inte förbättrar sin hållbarhetsprestanda krävs större förändringar i konsumtionen och vice versa.

    De mål som sätts för försäljning/tillhandahållning till konsument i rapporten är avsedda att användas av aktörer som säljer eller på annat sätt har möjlighet att påverka konsumtionsmönster, som exempelvis handel, food service och den offentliga måltidssektorn. Dessa mål ger en bild av faktisk slutkonsumtion. De mål som sätts för produktionen, alltså produktionens värdekedjor, är avsedda att användas av aktörer som producerar livsmedel, alltså lantbruk och livsmedelsindustri.

    Det var inte möjligt att sätta kvantitativa mål för alla relevanta hållbarhetsaspekter, för vissa aspekter finns inga vetenskapliga uppskattningar av den hållbara nivån för påverkan. Brist på metodik och data är ett annat allvarligt hinder för att sätta operativa mål. I rapporten har dessa kunskapsluckor identifierats och alternativa mål har föreslagits för att alla aspekter ska kunna hanteras konkret. Med alternativa mål menas mål som kan bygga på indirekta mått på hållbarhet som exempelvis energibesparingsmål istället för ett mål om hur stor den totala energianvändningen kan vara, då detta inte finns kvantifierat.

    Sustainability checklist in support of the design of food processing2018In: Sustainable Production and Consumption, ISSN 2352-5509, Vol. 16, p. 110-120Article in journal (Refereed)
    Abstract [en]

    To source food ingredients produced by best practice, reducing food loss in the processing line and implementation of new technologies are some examples of changes in the management in the food and drink sector that may offer advantages from a sustainability perspective. There are several tools and methods for evaluating sustainability for a food processing technology but often specific methodological knowledge is essential and many companies may not be able to carry out such a study due to time constraints and lack of data. The aim of this paper is to provide a tool with the format of a qualitative sustainability checklist, based on existing Life Cycle Assessment theory. The checklist is devoted to the design and adaptation of processing in the food industry to clarify the potential hot spots in new process design and is focused on environmental sustainability, although other aspects were conferred as well to demonstrate its potential. To identify the potential of this kind of checklist, it was tested by four food companies. The participant feedback was in general positive. The companies highlighted the benefits of creating awareness of sustainability issues within the company and providing a good overview without data collection. From a scientific point of view, the approach can help to overcome several challenges in sustainability assessment in the agri-food sector, especially some modeling issues and spatio-temporal resolution. © 2018 The Authors

    Mapping the EU tomato supply chain from farm to fork for greenhouse gas emission mitigation strategies2021In: Journal of Industrial Ecology, ISSN 1088-1980, E-ISSN 1530-9290, Vol. 25, no 2, p. 377-389Article in journal (Refereed)
    Abstract [en]

    Tomato and tomato products are the most consumed vegetables worldwide. However, reduction of their relatively high emission intensity can be a key to mitigating greenhouse gas (GHG) emissions of the agrifood sector. Using the European Union (EU) and its 28 member states as example, we mapped the mass flow and analyzed the efficiency of the entire tomato supply chain from farm to fork for the year 2016. We then explored potentials of a full spectrum of GHG emission mitigation strategies ranging from production-efficiency improvement to process optimization, food-waste reduction, trade-pattern change, and diet-structure change, both individually and in an integrated framework. The results showed that 63% of tomato loss and waste occurred at the processing and consumption stages (over half in Italy and Spain), and 54% of GHG emissions were from production (notably greenhouse based). Although the reduction of tomato products consumption (considered as the substitution by other vegetables) presented the highest potential of emissions reduction, reducing retailing and consumption waste were found to have great effect on GHG emissions reduction as well for all EU member states, especially for United Kingdom and Germany. The combined effects of different mitigation strategies with high levels of change could reduce GHG emissions by 39% compared to the current level.

    Missing Food, Missing Data?: A Critical Review of Global Food Losses and Food Waste Data2017In: Environmental Science and Technology, ISSN 0013-936X, E-ISSN 1520-5851, Vol. 51, no 12, p. 6618-6633Article in journal (Refereed)
    Abstract [en]

    Food losses and food waste (FLW) have become a global concern in recent years and emerge as a priority in the global and national political agenda (e.g., with Target 12.3 in the new United Nations Sustainable Development Goals). A good understanding of the availability and quality of global FLW data is a prerequisite for tracking progress on reduction targets, analyzing environmental impacts, and exploring mitigation strategies for FLW. There has been a growing body of literature on FLW quantification in the past years; however, significant challenges remain, such as data inconsistency and a narrow temporal, geographical, and food supply chain coverage. In this paper, we examined 202 publications which reported FLW data for 84 countries and 52 individual years from 1933 to 2014. We found that most existing publications are conducted for a few industrialized countries (e.g., the United Kingdom and the United States), and over half of them are based only on secondary data, which signals high uncertainties in the existing global FLW database. Despite these uncertainties, existing data indicate that per-capita food waste in the household increases with an increase of per-capita GDP. We believe that more consistent, in-depth, and primary-data-based studies, especially for emerging economies, are badly needed to better inform relevant policy on FLW reduction and environmental impacts mitigation.

    Efficiency and Carbon Footprint of the German Meat Supply Chain2019In: Environmental Science and Technology, ISSN 0013-936X, E-ISSN 1520-5851, Vol. 53, no 9, p. 5133-5142Article in journal (Refereed)
    Abstract [en]

    Meat production and consumption contribute significantly to environmental impacts such as greenhouse gas (GHG) emissions. These emissions can be reduced via various strategies ranging from production efficiency improvement to process optimization, food waste reduction, trade pattern change, and diet structure change. On the basis of a material flow analysis approach, we mapped the dry matter mass and energy balance of the meat (including beef, pork, and poultry) supply chain in Germany and discussed the emission reduction potential of different mitigation strategies in an integrated and mass-balance consistent framework. Our results reaffirmed the low energy conversion efficiency of the meat supply chain (among which beef was the least efficient) and the high GHG emissions at the meat production stage. While diet structure change (either reducing the meat consumption or substituting meat by edible offal) showed the highest emissions reduction potential, eliminating meat waste in retailing and consumption and byproducts generation in slaughtering and processing were found to have profound effect on emissions reduction as well. The rendering of meat byproducts and waste treatment were modeled in detail, adding up to a net environmental benefit of about 5% of the entire supply chain GHG emissions. The combined effects based on assumed high levels of changes of important mitigation strategies, in a rank order considering the level of difficulty of implementation, showed that the total emission could be reduced by 43% comparing to the current level, implying a tremendous opportunity for sustainably feeding the planet by 2050.

    Food waste prevention strategies in global food chains: Conclusions and recommendations from the SIANI Expert group on food waste 20162016Report (Other academic)
    Abstract [en]

    Around 1/3 of edible food produced is wasted and when converted into calories this losscorresponds to 1/4 of the nutritional energy from food. Reducing food waste is a “triplewin” activity: as it saves money since less resources are needed, as less waste is equal tothe opportunity to feed more people in the future, and furthermore reduced wastedecreases the pressure on climate, water, and land resources. The need to reduce foodwaste is also a part sustainability goals (SDG12.3). The success in reducing food waste ishighly dependent on an effective communication across the supply chain since the truecause of food waste many times is found in other parts of the supply chain than it where itactually happens. Such circumstances are particularly challenging in global food chainsin particular food chains starting in developing countries ending in high income countriesdue to the geographic distance and the involvement of many actors.The aim of this project, coordinated by the “SIANI” Expert group on food wastepreventions strategies in global food chains” was to gather current knowledge andexperience, as well as best practice on how to manage food chains starting in developingcountries ending in high income countries with focus on vegetables and fresh fruits. Thiswas done by taking a multi-stakeholder perspective, by a survey and a workshop, toidentify knowledge gaps and opportunities:The specific questions raised in the project were:• How can our way of managing global food chains support the farmer in lowincome countries?• How can best practice in high income countries (e.g. Sweden) decrease the foodwaste of imported food by e.g. appropriate labelling, appropriate businessmodels, consumer information etc.?• How can best practice in our (Swedish) food chains be transferred to low incomecountries, improving the local food chain to the benefits of the local actors? Sinceglobal and local food markets are communicating vessels the hypothesis is that awell-functioning local food chain will lead to less overall food waste and moreincome to the farmers.The gap analysis shows that there are large knowledge gaps on how the supply chainsfunction, how much food is wasted and the causes of the food waste. The survey carriedout also shows that there is a demand for political action, and resources are needed inorder to make a change:

    − To facilitate and enable actions directed towards minimising food waste,recourses are needed for: education and training, technology implementation,better infrastructure and communication in the food system. This is importantwhen trading with developing countries and poor farmers with low educationalbackground.− The transparency, particularly in long supply chains, is problematic asinformation seems to be lost the longer the chain is; this is especially challengingwhen working with developing countries where the knowledge gap and theability to be a strong partner compared to the large industries and retailers ischallenging. Other aspects of transparency that needs to be addressed is thesharing information on e.g. campaigns, and other activities having an influenceon the demand along the food supply chain.− The survey shows that there is much knowledge in place that is not shared alongthe supply chain. Round table discussions and knowledge sharing within different sectors may be a first step in making use of current know-how, and to set up anagenda on needs and how to collaborate− To facilitate and enable actions directed toward minimising food waste, recoursesare needed for: education and training of all those in the early stages of the supplychain, technology implementation, better infrastructure and communication in thefood system. This is important when trading with developing countries and poorfarmers with low educational background.

    Much research is ongoing relating to sustainable food production without considering theresearch question being central for reducing food waste. Food waste research still suffersfrom that it is a quite new research area that is under development. Research focus onglobal food chains is currently focusing on quantification of food waste, impact ofinformation activities and awareness raising activities and is focused on the situation inhigh income countries. Addressing food waste in global food chains as defined in thisreport shows that research adapted to the needs in the local food chains in developingcountries are needed. For example how can a farmer make use of IT in a simple way(almost every farmer has a mobile phone), are there packing solution that can be usedtropical fruits so that a desired even quality can be delivered, how to handle the waste thatstill happens in the best way (feed, new product, biogas etc.) and how to take care of theinedible parts (leaves, stems, peels etc.). Process technologies suitable for small scaleapplications, e.g. by processing fruits having a low quality it can be preserved and sold asexported as processed fruit instead of being unsold or sold to the local market to a muchlower price.The Swedish resource base and research network could contribute to more sustainableand fair food chains with less waste by sharing their knowledge and take actionsaccording to:• Swedish Universities and Institutes could take a role in educating students andhosting visiting researchers to cover the knowledge gaps.• NGOs could take the important role as facilitators and educators in developingcountries on site.• The actors in the food supply chain can advance their position by dialogue,collaboration and information sharing; also, by hosting trainees from developingcountries learning Swedish best practice and serve as food “waste ambassadors”when they return back home.• Researcher and innovators could contribute to technology development,particularly simple, robust technological solutions to be used in developingcountries.• The key is however that Swedish actors we collaborate (researchers, innovators,food processors, retailers, authorities and policy makers) and share ourknowledge and experience in an organised way.

    The actual practical solutions for reducing food waste need to build on the collectedexperience and the knowledge carried by the actors in the supply chains and theresearchers working with problems relating to food from different perspectives. Abottom-up approach is needed being supported by appropriate policy intervention.Finally, although the field is hampered by the unclear ownership of the question and lackof collaboration, there is always a” working window” for each actor in the supply chainwhere improvements can take place right now. Numerous of examples and ideas areprovided in the report and its annex.
