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.

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

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.

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

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.

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.

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).

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)

Verktyget är utvecklat för kockar, köksmästare, måltidsbiträden och enhetschefer och kan användas i tillagningskök, mottagningskök och serveringskök. Syftet med denna rapport är att med utgångspunkt från Göteborgs Stads arbete kring Göteborgsmodellen för mindre matsvinn, belysa och analysera data och erfarenheter från genomförandet av ett storskaligt matsvinnsprojekt. Göteborgs Stad har en stor måltidsverksamhet med cirka 520 kök som serverar drygt 80 000 luncher per dag. Genom Göteborgsmodellen för mindre matsvinn har Göteborgs Stad på två år, från januari 2017 till december 2018, minskat sitt matsvinn (serveringssvinn och kökssvinn) i sina kök med 50%, från cirka 30 g/portion till 15 gram/portion. I slutet av projektet mätte 95% av köken sitt matsvinn. Baserat på mätningarna 2017–2018 stod serveringssvinnet för cirka 80% av matsvinnet medan 20% var kökssvinn. Arbetet inom och förarbeten till projektet Göteborgsmodellen för mindre matsvinn har bidragit till nya nyckeltal för olika kategorier av kök i Göteborgs Stad. Projektet har också bidragit till systematiska och långsiktiga effekter genom att införa ett systematiskt arbetssätt. Genom att arbeta med modellen har köken etablerat rutiner för att minska köks- och serveringssvinn samt identifierat strukturella problem som måste lösas i framtiden för att minska matsvinnet ytterligare. Uppföljning av data från tidigare mätningar i kombination med mätningar gjorda inom Göteborgsmodellen, totalt 5 års mätningar, visar att det tar tid att genomföra en varaktig förändring. Generellt minskar matsvinnsnivåerna snabb i början för att sedan succesivt plana ut under loppet av flera år.

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.
