    Klimatavtryck från engångsförkläden i sjuk-vården2021Report (Other academic)
    Abstract [sv]

    Currently Swedish healthcare uses large amounts of disposable products, many of which are made from plastic. For example, Region Uppsala annually uses 3,2 million disposable plastic aprons. Currently these aprons are manufactured from fossil based polyethene plastic. This causes emissions of 270 tonnes of carbon dioxide equivalents over their life cycle from extraction of raw material to end of life through incineration. If substituting the fossil polyethene with plastic manufactured from renewable material, there is a potential to reduce the climate impact from disposable plastic aprons. Current study has compared disposable plastic aprons made from fossil polyethene with aprons made from renewable raw materials. Two renewable plastics were evaluated, disposable apron made of polyethene manufactured from bioethanol from Brazilian sugar cane and disposable aprons made of the renewable plastic polylactide (PLA) origination from sugar cane grown in Thailand. The result is that using biopolyethene reduces climate impact with 60 % and PLA aprons with 40 % compared to fossil polyethene. PLA has a component that currently is of fossil origin. If in the future this component is substituted with a renewable component there is a potential to reduce the PLA climate impact with as much as 20 % compared to current reduction in comparison to fossil polyethene.

    The connected, sustainable and inclusive society – IoT implementation in a Swedish municipality2022In: E3S Web of Conferences, Vol. 349, article id 11006Article in journal (Refereed)
    Abstract [en]

    The Internet of Things (IoT) is expected to transform the way we live, work, and learn. Using IoT could thus be a game-changer for municipalities towards sustainability. The Swedish municipality of Södertälje strives to develop IoT concepts and use open data for a sustainable and inclusive society. The goal of this study was to explore how IoT can enable route optimization and placement planning for increased operational efficiency. The goal was also to enhance the knowledge of the environmental and social benefits of IoT systems in the waste collection system in Södertälje. The analysis is based on Life Cycle Assessment (LCA) and interviews. The results show a minor climate change impact for the IoT solutions in the overall smart waste collection system. The major climate impact contributor was instead associated with the trash bags used. Additionally, the study showed that the performance of the system relies on smart planning of the operations and the transportations.

    Life cycle assessment of Internet of Things(IoT) solution in Södertälje municipality– A smart waste collection system2021Report (Other academic)
    Abstract [en]

    Internet of things (IoT) is expected to transform the way we live, work, and learn. Using IoT can be a game-changer for municipalities to move towards sustainability. Within the Vinnova financed project, the municipality wants to explore how IoT can enable route optimization and placement planning for increased operational efficiency. The aim of this study is to enhance the knowledge of the environmental benefits of IoT systems in the waste collection system in the city center of Södertälje. This life cycle assessment, LCA, will support the project by identifying environmental hotspots. The LCA study was performed in Jan-Sep 2021. The functional unit of the study has been set to 1 year of IoT system service for 160 litter bins in city center of Södertälje. The studied system is a cradle-to-grave system, including raw materials, sensors and gateways, use phase, and end of life the sensors and gateways, internet connection, as well as the cloud services. Inventory information have been collected mainly from Södertälje, suppliers, and the service providers. Generic data, such as electricity mix, and transports have been taken from the Ecoinvent database and literature. This study has evaluated the environmental impacts of IoT system in Södertälje for the case of smart waste collection system installed in the city center in a life cycle perspective. The objective of the study has been: 1. To estimate the environmental impact (with focus on climate change impact) of IoT system in Södertälje and find out the hotspots within the system in a life cycle perspective. The climate change impact of the IoT system solution in Södertälje is estimated about 120 kg CO2eq per year, which mainly contributes from the gateways (50%) and sensors (27%) and the use of internet (23%). 2. To estimate the environmental impact (focus on climate change impact) of the waste collection system (without IoT system) and find out the hotspots within the system. The climate change impact of the current waste collection system in the city centre of Södertälje contributes approximately 12t CO2eq per year, which mainly contributed from the use of fossil-based plastic trash bags (96%) and the HVO based transport (4%). 3. To compare the current with the future waste collection system (including IoT system for planning and service). To compare the current with the future waste collection system, we use scenarios (see Figure 20 for results). At the starting point of the study (scenario 1), we present results that are based on assumptions and have the same CO2 emissions for the transport and the trash bags. The results were based on diesel (50%) and recycled plastic trash bags (50%). The recycled plastic is made of 80% recycled LDPE and 20% virgin LDPE (Tingstad, 2021). The next step (scenario 2) of the study, we present results that are based on direct data of the current system. The results were based on HVO and fossil trash bags, which results into 11.5 t CO2 for fossil bags and 380 kg CO2eq per year for transport and 120 kg CO2eq extra for the IoT system. The last step (scenario 3) of the study, we present results that are based on future assumptions. The results were based on using no bags and no CO2 emission from bags, which results into 120 kg CO2eq for the IoT system and 380kg CO2eq for the transport and 0 kg CO2eq for the trash bags. The future waste collection system needs to be better than the current system. That means, the future waste collection system needs to reduce the CO2eq emissions by at least 120 kg CO2eq to break-even the extra IoT system. For the IoT system to have an effect, at least 32% of the transport (km) or the number of trash bags used need to be reduced (50 bins of 160 bins), in order to outweighs the extra CO2eq from the IoT system (Figure 21). - A reduction of trp km or trash bags by 32% reduce CO2eq by 120 kg. (=IoT system). - A reduction of trp km or trash bags by 64% reduce CO2eq by 240 kg. (> IoT system).

    Manual för plockanalyser av brännbart bygg- och rivningsavfall2019Report (Other academic)
    Abstract [en]

    This manual provides instructions on how to perform sorting analyses of combustible construction and demolition waste studied in the project Framtidens avfallsbränsle – Uppströmsarbete och kvalitet.The sorting strategy described in this manual recommends sorting out the content of the waste sample based on its composition (referred to as main fractions) and functionality (referred to as subfractions). In this way, four material fractions are identified and sorted out (i.e. plastic, paper, wood and “others combustible and non-combustible materials”), and up to 48 different subfraction (i.e. plastic pipes, wooden furniture, packaging paper, cables, metal pieces etc.).It is important to mention that the subfractions listed in this report are indicative: not all of the subfractions listed are always found in the combustible construction and demolition waste. Additions or substitutions may be necessary to ensure the best outcomes from the sorting analyses depending on the aim and goals of the project.The way the waste sample is handled before a sorting analysis is performed is essential. For that reason, this manual also includes instructions about sample collection, identification and storage once the sample is received at the sorting waste plants; as well as brief recommendations about how to perform a pre-sorting of those materials with a potential for recycling and waste which can be easily removed.

    Energy and climate-efficient construction systems: Environmental assessment of various frame options for buildings in Brf. Viva2018Report (Other academic)
    Abstract [en]

    In the collaborative forum Positive footprint housing® Riksbyggen is building the Viva residential quarter, which is a sustainability project at the very forefront of what is possible with contemporary construction. The idea is that this residential quarter should be fully sustainable in ecological, economic and social terms. Since 2013, a number of pilot studies have been completed under the auspices of the Viva project framework thanks to financing from the Swedish Energy Agency. The various building frame alternatives that have been evaluated are precast concrete, cast in-situ concrete and solid wood, all proposed by leading commercial suppliers. The report includes a specific requirement for equivalent functions during the use phase of the building, B. An interpretation has been provided that investigates the building engineering aspects in detail, as well as an account of the results based on the social community requirements specified in Viva, durability, fire, noise and energy consumption in the Swedish National Board of Building, Planning and Housing building regulations (BBR), plus Riksbyggen’s own requirements, Sweden Green Building Council’s Environmental Building Gold (Miljöbyggnad Guld) and 100-year life cycle. Given that the alternatives have different long-term characteristics (and also that our knowledge of these characteristics itself varies), these functional requirements have been addressed by setting up different scenarios in accordance with the EPD standard EN 15978. Because Riksbyggen has specified a requirement for a 100-year life cycle, we have also opted for an analysis period of 100 years. The results show no significant differences between concrete and timber structures for the same functions during the life cycle, either for climate or for primary energy. The minor differences reported are accordingly less than the degree of uncertainty involved in the study. The available documentation on the composition of the relevant intumescent paint coating on solid wood frames differs from source to source, so it was not possible to fully allow for the significance of this. The LCA has not included functional changes in the building linked to load-bearing characteristics, noise, moisture, health or other problems that may result in increased maintenance and replacement. The concrete houses have been dimensioned for 100 years, for instance, in accordance with tried and tested standards and experience. The solid wood house is not dimensioned in the same way, and this has led to us having to assume various scenarios.

    The results also show the following:

    • The uncertainties involved in comparing different structures and alternative solutions are very significant. The results are affected by factors such as life cycle, the functional requirements taken into consideration, transportation, design and structural details, etc.

    • Variations in the built items and a considerable degree of uncertainty in the assumptions make it difficult to obtain significant results on comparisons. Only actual construction projects with known specific data, declared from a life cycle perspective that takes into account actual building developer requirements and involving different scenarios (best, documented and worst-case) for the user stage can currently be compared.

    • In the other hand, comparisons restricted to different concrete structures only, or to different timber structures only, ought to involve a lower degree of uncertainty. These would then provide results that are significant as well as improvement requirements that are relevant.

    • There is potential for improving concrete by imposing requirements on the material

    • There is potential for improving solid wood frames by developing and guaranteeing well-documented long-term characteristics for all functional requirements.

    The LCAs were performed as an iterative process where all parties were given the opportunity to submit their viewpoints and suggestions for changes during the course of the work. This helped ensure that all alternatives have been properly thought through.

    Because, during the project, Riksbyggen opted to procure a concrete frame, in the final stage the researchers involved focused on ensuring the procurement process would result in the concrete frame as built meeting the requirements set out above. As things currently stand, the material requirements for the concrete are limited by the production options open to the suppliers, and this is therefore being investigated in the manufacture of precast concrete frames for the Viva cooperative housing association.

    Iron as recyclable electrofuel: Effect on particle morphology from multiple combustion-regeneration cycles2024In: Combustion and Flame, ISSN 0010-2180, E-ISSN 1556-2921, Vol. 259, article id 113137Article in journal (Refereed)
    Abstract [en]

    This work describes the morphological and material changes in the iron powder during four regeneration-combustion cycles. The regeneration in H2 and combustion in air experiments were made in a fluidized bed (FB) and an entrained flow reactor (EFR), respectively. The average size of the iron oxide particles more than doubled between the first and fourth combustion cycles, and many of the particles were hollow. The regeneration step did not change the size of the particles but increased their porosity. A mechanism is proposed that describes the formation of large-diameter hollow particles which increases as a function of the regeneration-combustion cycles. The observed increase in particle size and the change in particle morphology complicates the iron fuel concept, as it leads to a degradation of the structural stability of the particle with time.

    Solcelleteknologi og brannsikkerhet2018Report (Other academic)
    Abstract [en]

    The use of photovoltaic (PV) technology in Norway is increasing. In this study, fire safety challenges of PV technology are studied. Fire ignition, fire spread and fire extinguishing are investigated. The study forms a knowledge base for safeguarding fire safety during assembly, operation and during firefighting efforts, and to form unified and clear regulations. The results show:

    Fire ignition: PV installations contain many electric connections which can be potential ignition sources, as well as a small volume of combustible materials. These provide everything needed to initiate a fire. It is important that all connections in a PV installation are robust and can withstand the stress they are exposed to throughout their lifetime, without causing malfunction that could cause a fire.

    Fire spread: For building attached photovoltaics, there are cavities between the module and the building. If there is a fire in this cavity, the produced heat could be trapped, which could lead to a more rapid and extensive fire spread than if the building surface were uncovered. In large scale tests with PV modules mounted on a roof covering, the fire spread under the whole area covered with modules, but stopped when approaching the edge. This demonstrates the importance of sectioning when mounting PV installations, to avoid fire spread to the whole roof. An option is to use materials with limited combustibility as roof covering below the PV module, to withstand the increased heat exposure from the PV modules. The cavity between module and building could potentially also alter the air flow along the building, which in turn could affect the fire spread.

    Firefighting: Firefighters need information on whether there is a PV installation in the building, and where there are electrical components. During firefighting efforts, the fire service must consider the danger of direct contact, and danger of arcs and other faults that could lead to new ignition points. Fresh water can be used as an extinguishing agent. This must be applied from at least 1 meter distance with spread beam and at least 5 meters distance with a focused beam. PV modules can complicate fire extinguishing as they represent a physical barrier between the fire fighter and the area to extinguish, and by creating areas which should be avoided due to danger of components with voltage. When these points are considered, building attached photovoltaics should not be a problem.

    Further work: For building attached photovoltaics, there is little research on vertical mounting (on facades), and on how changed fire dynamics could affect fire spread and extinguishing. Also, today there is an increasing use of building integrated photovoltaics, which could potentially give many new challenges for fire safety and for regulations, as these are a part of the building and at the same time electrical components. German statistics indicate that there is an increased fire risk for these types of installations, compared to building attached photovoltaics, making this an important focus area for further work.

    Food waste as a resource for bio-based chemicals and materials in Sweden2019Report (Other academic)
    Abstract [en]

    Waste, also food waste, abound. From an environmental point of view food waste should first and foremost be avoided. However, the waste that inevitably is produced along the food production chain should be utilized to the best of our ability. One option is to produce biobased chemicals and materials from the waste through biological processes. This study looks into what food waste resources are available for such production, industrial fermentation, in Sweden, from waste emanating in primary production all the way through to final consumption. In addition, drivers for waste generation, influencing institution and waste market characteristics are assessed.

    Climate impact of metal-casting2016Report (Other academic)
    Abstract [en]

    Swerea SWECAST was commissioned by the Swedish Foundry Association to update the background report for the carbon footprint indicator which was first put forward in 2011.

    The aim of the work was to analyze the emission of CO2 for thirteen foundry producing countries when producing one tonne of cast product.

    The Swedish Environmental Research Institute, IVL, has on Swerea SWECAST mission produced a report with general data on carbon dioxide emissions from electricity consumption from thirteen countries.

    Based on the background data presented by IVL and assumptions, calculations have been made for a number of different metals. The results are an indication that there are climatic differences depending on the country the cast components is manufactured in. In essence, it is the countries' electricity mix that controls the outcome, where Sweden is very well, because electricity from hydro and nuclear power produce low emissions of greenhouse gases in the operating phase.

    A risk with this kind of work is that the result is taken as income for not working with energy efficiency in the Swedish foundries. So should not the results be interpreted. If foundries in other countries or individual foundries are working to streamline its process and the Swedish foundries don’t there is the risk that the Swedish foundries after all end up behind.

    Substantial global carbon uptake by cement carbonation2016In: Nature Geoscience, ISSN 1752-0894, E-ISSN 1752-0908, Vol. 9, no 12, p. 880-883Article in journal (Refereed)
    Abstract [en]

    Calcination of carbonate rocks during the manufacture of cement produced 5% of global CO 2 emissions from all industrial process and fossil-fuel combustion in 2013. Considerable attention has been paid to quantifying these industrial process emissions from cement production, but the natural reversal of the process - carbonation - has received little attention in carbon cycle studies. Here, we use new and existing data on cement materials during cement service life, demolition, and secondary use of concrete waste to estimate regional and global CO 2 uptake between 1930 and 2013 using an analytical model describing carbonation chemistry. We find that carbonation of cement materials over their life cycle represents a large and growing net sink of CO 2, increasing from 0.10 GtC yr â '1 in 1998 to 0.25 GtC yr â '1 in 2013. In total, we estimate that a cumulative amount of 4.5 GtC has been sequestered in carbonating cement materials from 1930 to 2013, offsetting 43% of the CO 2 emissions from production of cement over the same period, not including emissions associated with fossil use during cement production. We conclude that carbonation of cement products represents a substantial carbon sink that is not currently considered in emissions inventories.
