    Expanding roles for the Swedish waste management sector in interorganizational resource management2017In: Resources, Conservation and Recycling, ISSN 0921-3449, E-ISSN 1879-0658, Vol. 124, p. 85-97Article in journal (Refereed)
    Abstract [en]

    Several waste management (WM) professionals see an ongoing shift in the focus of the industry, from that of atransport and treatment sector to that of a more integrated sustainable service provision and material productionsector. To further develop such transitional ambitions, WM organizations are increasingly looking toward interorganizationalresource network concepts (such as the circular economy and industrial symbiosis) as models ofhow they would like to create new value together with their customers and partners.This article aims to take a step in addressing uncertainties behind such transitions by analyzing barriers forinter-organizational resource management and in turn uncovering some potential opportunities and risks ofnovel offerings from the WM sector. Obstacles for developing innovative inter-organizational resource networkshave been identified based on studies of implementing industrial symbiosis networks. Subsequently, managingexecutives from Swedish private and public WM organizations were interviewed regarding the sector’s capacityto overcome such barriers – opportunities and risks of providing new resource management services – and howtheir organizations might approach the role of actively facilitating more resource efficient regions.Eco-Industrial park management and contracting out holistic resource management are some areas in whichthe respondents see WM organizations offering new services. In relation to such approaches, various risks (e.g.being cut out of investment benefits, or unstable supply) and opportunities (e.g. new markets and enhancedsustainability profiles) were identified. Additionally, it was seen that WM companies would need to makesubstantial changes to their business approach, becoming less dependent on flows of mixed materials forexample, if they are to become even more central value chain actors. To strengthen such approaches, it was seenthat the sector will need to find methods to strategically build strong, long term partnerships, expand upon andtake advantage of available knowledge resources (i.e. best practice technologies and regional material flows),and explore new business models (i.e. stockpiling, park management, or waste minimization). Additionally,working with sector representatives to argue for a more balanced market conditions next to primary productionshould assist the viability of new offerings in the wider market.

    Biogas in the transport sector: Actor and policy analysis focusing on the demand side in the Stockholm region2018In: Resources, Conservation and Recycling, ISSN 0921-3449, E-ISSN 1879-0658, Vol. 129, p. 70-80Article in journal (Refereed)
    Abstract [en]

    Sweden has ambitions to phase out fossil fuels and significantly increase the share of biofuels it uses. This articlefocuses on Stockholm County and biogas, with the aim to increase the knowledge about regional preconditions.Biogas-related actors have been interviewed, focusing on the demand side. Biogas solutions play an essentialrole, especially regarding bus transports and taxis. Long-term development has created well-functioning sociotechnicalsystems involving collaboration. However, uncertainties about demand and policy cause hesitation andsigns of stagnating development.Public organizations are key actors regarding renewables. For example, Stockholm Public Transport procuresbiogas matching the production at municipal wastewater treatment plants, the state-owned company Swedaviasteers via a queuing system for taxis, and the municipalities have shifted to “environmental cars”.There is a large interest in electric vehicles, which is expected to increase significantly, partially due tosuggested national policy support. The future role of biogas will be affected by how such an expansion comesabout. There might be a risk of electricity replacing biogas, making it more challenging to reach a fossil-freevehicle fleet. Policy issues strongly influence the development. The environmental car definition is of importance,but its limited focus fails to account for several different types of relevant effects. The dynamic policylandscape with uncertainties about decision makers’ views on biogas seems to be one important reason behindthe decreased pace of development. A national, long-term strategy is missing. Both the European Union andSweden have high ambitions regarding a bio-based and circular economy, which should favor biogas solutions.

    Assessment of Feedstocks for Biogas Production, Part II: Results for Strategic Decision Making2017In: Resources, Conservation and Recycling, ISSN 0921-3449, E-ISSN 1879-0658, Vol. 122, p. 388-404Article in journal (Refereed)
    Abstract [en]

    Biogas production is essentially based on organic materials and biological processes; hence it can contribute to the transition toward a biobased economy. Biogas is a biofuel that can contribute to a more renewable and local energy system. In comparison with other biofuels, biogas is more flexible and can be produced from many different types of feedstock, including biomass containing various shares of carbohydrates, lipids and, both from primary and secondary raw materials. However, a significantly expanded biogas production is dependent on good business conditions, in turn related to societal acceptance and support. There are many factors that can make a biogas solution more or less suitable for both producers and the broader society. Among the many influencing factors, the choice of feedstocks (biomass) for producing biogas and biofertilizer is of strategic importance. But, to assess the suitability is complicated, because it is linked to many different challenges such as cost, energy balance, environmental impacts, institutional conditions, available technologies, geographical conditions, alternative and competing interest, and so on. Suitability includes aspects related to feasibility for implementation, potential for renewable energy and nutrient recycling, and resource efficiency. In this article, a multi-criteria framework, which is proposed in a companion article (Part II), is used to assess the suitability of four types of feedstocks for producing biogas (considering Swedish conditions). The assessed feedstocks are ley crops, straw, farmed blue mussels, and source-sorted food waste. The results have synthesized and structured a lot of information, which facilitates considerably for those that want an overview and to be able to review several different areas simultaneously. Among the assessed feedstocks, biogas production from household food waste and ley is the most straightforward. For straw and farmed blue mussels, there are more obstacles to overcome including some significant barriers. For all feedstock there are challenges related to the institutional conditions. The assessment contributes to the knowledge about sustainable use of these feedstocks, and the limitations and opportunities for biogas development. It supports more informed decision making, both in industry and policy. Existing, or forthcoming, biogas and biofertilizer producers who are considering altering or expanding their production systems can benefit from a better understanding of different choices of feedstock that are or can be (potentially) at their disposal; thus, identify hotspots, weak points, and possible candidates for implementation in future. This research is performed within the Biogas Research Center (BRC), which is a transdisciplinary center of excellence with the overall goal of promoting resource-efficient biogas solutions in Sweden. The BRC is funded by the Energy Agency of Sweden, Linköping University, and more than 20 partners from academia, industry, municipalities and other several public and private organizations.

    The role of biogas solutions for enhanced nutrient recovery in biobased industries-three case studies from different industrial sectors2021In: Resources, Conservation and Recycling, ISSN 0921-3449, E-ISSN 1879-0658, Vol. 175, article id 105897Article in journal (Refereed)
    Abstract [en]

    This study analysed to what extent biogas solutions can improve the nutrient recovery of biobased industrial clusters in different sectors. Three cases representing the agricultural, marine and forest sectors were analysed quantitatively using mass flow analysis. Adding a biogas plant facilitated production expansion and development of collaborative waste management, e.g. a wheat processing biorefinery with a mill and agricultural actors, or a pulp and paper mill with the aquaculture industry. In the marine- and forest-based cases, this decreased the total nitrogen (N) and phosphorous (P) input by 18% while increasing the recovery rate; e.g. for P from 32 to 96% for the marine-based and from 52 to 91%, for the forest-based. The impact in the agro-based case was minor as the actors were already operating with a high nutrient recovery. For the marine-based case, the impact was due to a huge increase in P recovery for the aquaculture actor while for the forest-based case, N from the aquacultural sector could be reused in the wastewater treatment. For the agro- and marine-based cases, adding a biogas plant also resulted in less transports and more local nutrient recycling; the total transport of organic waste, by-products and biofertilizers (in km x tonne) was reduced by 40% and 90%, respectively. The results demonstrate that biogas solutions can stimulate the development of biobased industrial symbiosis with integrated waste management, and contribute to more efficient recycling of key resources, which is essential for the transition to a circular society.

This framework allows learning about the limitations and opportunities for biogas development and more informed decision making, both in industry and policy. Existing, or forthcoming, biogas and biofertilizer producers who are considering altering or expanding their production systems can benefit from a better understanding of different choices of feedstock that are or can be (potentially) at their disposal; thus, identify hotspots, weak points, and possible candidates for implementation in future. The framework is reasonably comprehensive, yet it is simple enough to be used by practitioners. It could help to minimize the risk of sub-optimization or neglecting important risks or opportunities. This article, the first of two associated articles, is focused on the framework itself. The framework is applied to assess the suitability of producing biogas from “stickleback”, which is a non-edible fish in the Baltic Sea region. In the companion article (Part II), four other feedstocks are assessed, namely ley crops, straw, farmed blue mussels, and source-sorted food waste.

    Potential valorisation of shredder fines: Towards integrated processes formaterial upgrading and resource recovery2020In: Resources, Conservation and Recycling, ISSN 0921-3449, E-ISSN 1879-0658, Vol. 154, article id 104590Article in journal (Refereed)
    Abstract [en]

    The lack of process development based on a comprehensive understanding of the material characteristics and the marketability of recoverables is the primary reason why the valorisation of shredder fines has not been realised in practice. In response, a systematic approach was undertaken consisting of 1) strategic sampling and material characterisation, 2) establishing gate and regulatory requirements of potential valorisation applications, and 3) initial feasibility assessment of the selected applications, to guide future research.

    The material was sampled over ten weeks in order to obtain both average values and variations of the physical and chemical composition. Thus weekly, primary fractions and sieved fractions ZA (7.10–5.00 mm), ZB (5.00–3.35 mm), ZC (3.35–2.00 mm), ZD (2.00–0.25 mm), and ZE (0.25–0.063 mm) were prepared, and analysed, and benchmarked against the requirements pertaining to five potential applications. The mercury and aluminium concentrations are the biggest challenge in copper smelting and only ZA and ZB show significant potential. Energy recovery is limited to ZA, ZB, and ZC, provided the chlorine and metals concentrations are decreased. Regarding the recovery as bulk-material in construction, the reduction of the metal content would likely be a pre-requisite.

    The utilisation of fines in the individual applications would either leave a significant amount of fines un-valorised or overlook the recovery of valuable resources. The upgrading of the material to suit the different applications would also require addressing multiple material constraints simultaneously. Therefore, realising the full resource potential of shredder fines would require the integration of different upgrading and recovery processes.

    Effect of the use of industrial excess heat in district heating on greenhouse gas emissions: A systems perspective2015In: Resources, Conservation and Recycling, ISSN 0921-3449, E-ISSN 1879-0658, Vol. 100, p. 81-87Article in journal (Refereed)
    Abstract [en]

    European policy promotes increased use of excess heat as a means to increase the efficiency of resourceuse. By studying possible effects on greenhouse gases, this article aims to analyze and discuss systemaspects of the use of industrial excess heat in district heating. Effects on greenhouse gas emissions arestudied by applying different energy market conditions with different system boundaries in time andspace. First, life cycle assessment is used to assess the introduction of excess heat in district heating in acontemporary system with different geographical system boundaries. Thereafter, future energy marketscenarios for Europe are investigated to explore possible future outcomes. This study concludes that boththe heat production system and the energy market conditions affect the system emission effects of usingexcess heat in district heating. Industrial excess heat in district heating can be beneficial even if it leadsto reduced local electricity production when unused biomass can be used to replace fossil fuels. It isrecommended that a strengthened EU policy should encourage the use of biomass where it has the mostfavorable effects from a systems perspective to ensure emission reductions when industrial excess heatis used in district heating.

    Using life cycle costing (LCC) to select circular measures: A discussion and practical approach2020In: Resources, Conservation and Recycling, ISSN 0921-3449, E-ISSN 1879-0658, Vol. 155, article id 104650Article in journal (Refereed)
    Abstract [en]

    The implementation of circular measures in businesses constitutes a solution to future resource scarcity, which has yet to gain momentum. To select and implement such measures, companies, with limited resources need practical and easy-to-use guides that help them understand the financial outcomes while leading them towards more circular solutions. To this end, a guideline based on Life Cycle Costing (LCC), which fulfils the aforementioned criteria, has been created. The guideline directs the companies towards measures at the top of the CE hierarchy and LCC is used to assess profitability and provide information on material circularity. Its development follows the Design Research Methodology (DRM) and is based on using LCC at three case companies when selecting circular measures and on literature. Insights on the companies’ processes and decision criteria as well as the LCC results are presented. One identified critical criterion is the profitability of a circular measure, but comparing the LCC of alternatives is only an adequate measure of profitability, if the alternatives are functionally equivalent and of equal value for the customer, otherwise revenue and customer costs need to be compared as well. In addition, because labour is included in LCC, by categorizing the costs companies can be guided towards exchanging material costs with labour costs. Concerning circularity, in this comparative context, the difference in material cost between the alternatives can be used to measure circularity performance without additional effort. Finally, customization of products was also identified in the company research as a barrier to the implementation of various circular measures.

    Evaluating waste management strategies: A case of metal-contaminated waste wood2007In: Resources, Conservation and Recycling, ISSN 0921-3449, E-ISSN 1879-0658, Vol. 52, no 1, p. 103-118Article in journal (Refereed)
    Abstract [en]

    In Sweden recovered waste wood (RWW) is used for heat production, which reduces the share of waste that is landfilled and recovers the energy content of the waste. However, this waste contains contaminated materials that pollute RWW with heavy metals, causing downstream environmental problems. The main objective of this study was to analyse how different upstream-oriented strategies to manage RWW, influence the arising of environmental pressures downstream the waste management system. Today, the contaminated materials in RWW are handled together with the main waste flow. This upstream approach was compared with a separation strategy that removes contaminants from the main waste flow thereby handling these materials separately downstream the waste management system. An extended substance flow analysis (SFA) methodology that also includes resource issues was applied for the analysis. The results show that the upstream separation strategy exhibits potential environmental benefits. However, to accurately prevent environmental pollution also in a long time perspective, upstream separation strategies must be combined with downstream measures aimed to immobilise the contaminants in by-products. Otherwise, such separation strategies, as the current handling of RWW, may cause temporal and spatial shifting of problems. To enable immobilising measures, however, upstream separation strategies are important since they decrease the volume problem.

    Resource-efficient treatment of organic industrial waste: Optimization of different treatment options using reMIND2023In: Resources, Conservation and Recycling, ISSN 0921-3449, E-ISSN 1879-0658, Vol. 197, article id 107065Article in journal (Refereed)
    Abstract [en]

    The aim of this work was to find the optimal resource-efficient treatment alternative for organic waste from the food industry. For that, four different treatment methods for thirteen feedstocks were studied: animal fodder production, incineration, biological treatment and biogas production. An optimization model was used to find which treatment alternative is the optimal from a variety of perspectives.The studied systems were evaluated from three different evaluation perspectives: economy, energy and environment. The energy evaluation included two different electricity systems: coal condensing power and wind energy.The results show that there is no single optimum feedstock treatment method taking all the perspectives studied into account. Instead, it is important to consider all different perspectives when evaluating the resource efficiency of the treatment method for a feedstock. However, both incineration and anaerobic digestion of the food waste can be considered as resource-efficient treatment options for the studied feedstocks.

    Reconfiguring repair: Contested politics and values of repair challengeinstrumental discourses found in circular economies literature2020In: Resources, Conservation and Recycling, ISSN 0921-3449, E-ISSN 1879-0658, Vol. 8, article id 100046Article in journal (Refereed)
    Abstract [en]

    The treatment of ideas of repair in circular economy literature is critically reviewed, revealing instrumental understandings of repair as a tool to extend product life-spans and reduce waste. These framings are interpreted as an expression of the dominant technocratic and post-political discourses of circular economy as an intervention to sustain industrial capitalism in the face of sustainability constraints. The review contrasts these understandings of repair derived from a review of circular economy literature with richer and contested interpretations found in sociological, ethnographic and political literatures examining material repair in practice. Drawing on the emerging sociology of repair and applying more distinct concepts of restoration, remediation, reconfiguration and reconciliation derived from these literatures, the paper argues that the understandings of repair in circular economy literature are limited and restrictive, generally supporting a view of repair as sustaining, consumerist and nostalgic; and thereby overlooking potentially transformative, political and future-oriented roles for repair in a circular economy. In the restorative and remedial modes most commonly understood in the circular economy, repair is seen to enable new forms of capitalist commodification, notably of waste and domestic labour. Learning from contestation in other arenas of repair by contrast, understanding repair as encompassing ideas for reconciliation and reconfiguration, and adopting values of integrity, care and legibility, opens up repair in the circular economy to constructive critical discussion and reflection and offers new insights for policy makers.

    Assessing the climate impact of district heating systems with combined heat and power production and industrial excess heat2015In: Resources, Conservation and Recycling, ISSN 0921-3449, E-ISSN 1879-0658, Vol. 86, p. 31-39Article in journal (Refereed)
    Abstract [en]

    Heat demand is a large contributor to greenhouse gas (GHG) emissions in the European Union (EU), as heat is largely produced using fossil fuel resources. Extended use of district heating (DH) could reduce climate impact, as DH systems can distribute heat produced in efficient combined heat and power (CHP) plants and industrial excess heat, thus utilising heat that would otherwise be wasted. The difficulty to estimate and compare GHG emissions from DH systems can however constitute an obstacle to an expanded implementation of DH. There are several methods for GHG emission assessments that may be used with varying assumptions and system boundaries. The aim of this paper is to illuminate how methodological choices affect the results of studies estimating GHG emissions from DH systems, and to suggest how awareness of this can be used to identify possibilities for GHG emission reductions. DH systems with CHP production and industrial excess heat are analysed and discussed in a systems approach. We apply different methods for allocating GHG emissions between products and combine them with different system boundaries. In addition, we discuss the impact of resource efficiency on GHG emissions, using the framework of industrial symbiosis (IS). We conclude that assessments of the climate impact of DH systems should take local conditions and requirements into account. In order for heat from CHP production and industrial excess heat to be comparable, heat should be considered a by-product regardless of its origin. That could also reveal opportunities for GHG emission reductions.

    The construction industry is associated with low productivity growth rates and environmental harm and, has a crucial role to play to reach the SDGs adopted by the UN in 2015. Construction logistics offer useful solutions to improve both the productivity and sustainability of the industry. The purpose of this paper is to investigate, in detail, the environmental impact of construction transport and whether the building certification scheme for a construction project has any influence on its transport arrangements. The analysis in this paper is based on a multiple case study of 40 Swedish projects. The results show that construction projects with better environmental ratings generated less emissions from construction transport. However, among the ten projects with highest transport/m2, five were certified. Construction logistics solutions (CLSs) such as terminals and checkpoints are useful in reducing the number of transports, and thereby reducing emissions. But the usefulness of a CLS is influenced by gross floor area and type of project, as well as the phase which the solution is implemented in. This study contributes to a better understanding of construction transport patterns and reducing environmental harm of these transports. The results of this paper are beneficial for construction site managers, logistics consultants and transport companies, helping them to implement CLSs in a more useful way, depending on the phase and type of project.

    Screening of environmental pressure from products in the Swedish railway infrastructure: Implications for Strategic Environmental Management2007In: Resources, Conservation and Recycling, ISSN 0921-3449, E-ISSN 1879-0658, Vol. 52, no 2, p. 248-265Article in journal (Refereed)
    Abstract [en]

    This paper proposes a method to be used in environmental reviews as an initial tool for estimating upstream environmental pressures from material use in organisations dealing mostly with construction materials. Upstream environmental pressures are often omitted in environmental reviews from organisations and instead tend to be site specific, with a limited life-cycle perspective. This paper uses the Swedish National Rail Authority as a case to present the approach. An energy indicator is used to estimate the environmental pressure of material use.

    In the studied building project, a small set of products contribute to a major part of the material use and the material-related energy use. The energy use is almost exclusively of nonrenewable energy carriers. The three most important products are all homogenous and non-complex, which makes the energy indicator well suited for the analysis. The organisation can use the results to focus on the most important products and also to see which parts of the organisation contribute to the material-related energy use. Rail traffic in Sweden is almost exclusively from non-fossil-based energy carriers. This highlights the importance of the infrastructure to the overall environmental pressure of the railway. Consequently, if road transport were to shift away from fossil fuels, railways earlier environmental advantages would diminish, since research suggests that railway infrastructure is more energy intensive than road infrastructure.

    The economic conditions for urban infrastructure mining: Using GIS to prospect hibernating copper stocks2015In: Resources, Conservation and Recycling, ISSN 0921-3449, E-ISSN 1879-0658, Vol. 103, p. 85-97Article in journal (Refereed)
    Abstract [en]

    In this article, we suggest a methodology that combines geographic information systems (GIS) and material flow analysis (MFA) into a secondary reserve-prospecting tool. The approach is two-phased and couples spatially informed size estimates of urban metal stocks (phase 1) to the equally spatially contingent efforts required to extract them (phase 2). Too often, even the most advanced MFA assessments stop at the first of these two phases, meaning that essential information needed to facilitate resource recovery, i.e., urban mining, is missing from their results. To take MFA one step further, our approach is characterized by a high resolution that connects the analysis of the stock to the social practices that arrange material flows in the city, thereby enabling an assessment of the economic conditions for secondary resource recovery.

    To exemplify, we provide a case study of the hibernation stock of copper found in disconnected power cables in Linköping, Sweden. Since 1970, 123 tonnes of copper or ≈1 kg per person have accumulated underneath the city, predominantly in old, central parts of the city and industrial areas. While shorter cables are more numerous than long ones, the longer ones contribute to a larger share of the stock weight. Resource recovery in specific projects reliant on digging comes at great costs, but integrating it as an added value to ordinary maintenance operations render eight locations and 2.2 tonnes of copper (2% of the stock) profitable to extract. Compared to the budget sizes of regular maintenance projects, the integrated recovery of a significant share of the stock comes with relatively small economic losses. Therefore, we suggest integrated resource recovery and regular maintenance as an interesting environmental measure for any infrastructure provider to engage with.

    What if everyone becomes a sharer?: A quantification of the environmental impact of access-based consumption for household laundry activities2020In: Resources, Conservation and Recycling, ISSN 0921-3449, E-ISSN 1879-0658, Vol. 158, article id 104780Article in journal (Refereed)
    Abstract [en]

    In order to meet the EU’s climate and resource efficiency targets, changes of our daily-life behaviors as well as business models are necessary. We developed a system dynamics model to analyze the environmental benefits of a transition from ownership-based to access-based household laundry activities. The model considers demographic, technological and behavioral aspects and assesses the environmental impact of laundry activities. The results indicate a significant potential of the sharing economy. The model is applied to the Swedish as well as the European context and allows cross-country comparisons. A higher utilization of shared machines, and extended lifespans of the machines can cut CO2 emissions by a third and avoid raw material usage in production. The carbon intensity of the energy mix is also important for the impact of the sharing economy.
