- Barriers to access-based consumption (ABC) have been extensively studied in different strands of literature. However, cumulative knowledge is not organized to date, and a comprehensive overview of barriers identified by empirical studies in diverse strands is lacking. Such a picture is essential for laying the ground for further change-oriented research and actual changes in practice. This article reports on the results of a systematic review on barriers to transitioning from ownership- to access-based consumption. The review focuses on the literature strands product-service systems, circular economy, sharing economy, and collaborative consumption. Through open and axial coding of 289 barriers reported in 45 empirical studies, we found 17 themes of barriers concerning consumers, business, and society. The analysis of the barriers reveals four significant insights important for the research and practitioner community:the overall experience of ABC and trust mechanisms need to be better understood;organizational aspects in traditional business need a system change;regulation plays a fundamental role in making ABC work for business, society, and sustainability; andsharing risks and experimentation for new learnings are necessary.These four major insights suggest that consumers need business and government to offer enabling conditions for ABC – spanning from raising awareness and understanding to improving user experience. Furthermore, businesses need governments to create the necessary structures to support ABC offerings – from decreasing risks to increasing incentives. How and which mechanisms can further facilitate circular behaviors is a salient topic for future investigations.

- In developing countries, urbanization and demographic changes are increasing food waste generation at household levels. However, it remains unclear how behavioural and personal characteristics influence the behaviours of urban consumers in developing countries regarding food waste. In this study, we extended the integrative model of behavioural prediction to examine the determinants of food waste behaviour amongst a sample of 698 urban dwellers in Addis Ababa, Ethiopia. The empirical results revealed that attitudes and perceived behavioural control were the most important predictors of intention toward food waste reduction. With regard to food waste behaviours, the results showed that the more an individual feels obliged to discard less food, the higher the odds that the quantity of food that gets wasted by the household would be reduced. Likewise, knowledge about the negative impacts of wasting food and an ability to interpret information on labels of food products were associated with decreased quantities of household food waste. In addition, lower psychological distance to food waste was generally associated with lower quantities of wasted food. Finally, sociodemographic characteristics and food-shopping routines were found to be significant predictors of food waste behaviours. Overall, these findings constitute an entry point for more research and policy measures in order to understand determinants of household food waste behaviours in developing countries and to design effective interventions to reinforce their behaviours towards more sustainable food consumption patterns.

Are second-hand shell jackets better than users think? A comparison of perceived, assessed and measured functionality throughout lifespans

- Using the case of outdoor shell jackets, this research studies obsolescence and potential lifespan extension by re-examining how product functionality, objectively and subjectively, develops over the course of product lifespans. In particular, the study focuses on second-hand stores for outdoor products. Functionality is indicated by user perceptions, visual assessments, laboratory measurements and price data, collected at first use, second-hand resale and end-of-life. Perceived functionality and price decline more rapidly (5–6 % per year) than assessed and measured functionality (around 3 % per year). This could be explained by properties related to appearance, which are not assessed nor measured but influence user perceptions and price. Discontentment regarding such properties appears more relevant for obsolescence than inadequate performance, suggesting the potential for design for attachment and timeless design. The relative stability of measured functionality over time suggests that a barrier for second-hand sales, concern about performance, could be ameliorated by a potential functionality-label.

Towards comprehensive assessment of mineral resource availability? Complementary roles of life cycle, life cycle sustainability and criticality assessments
- 2021

Forskningsöversikt (refereegranskat)abstract
- Regarding mineral resources, there is ambiguity around concepts such as scarcity, rarity, criticality and depletion and associated assessment methods. This paper investigates three method groups: life cycle impact assessment (LCIA), criticality assessment and life cycle sustainability impact assessment methods. The aim is to clarify how these method groups and concepts relate and their potential roles in a comprehensive mineral resource availability assessment. The study finds that their modeling approaches and practical implementations are sometimes misaligned with what they aim to assess. This results in similarities between methods from different method groups. Some LCIA-methods include elements which belong to criticality assessment, which could explain some of the ambiguity. A reason for misalignment is a lack of distinction between mineral resource stocks, funds and flows. The lack thereof also results in invalid impact pathway cause-effect chains and imprecise terminology allowing for misunderstandings in the “resource debate”. Distinguishing between mineral resource stocks, funds and flows resolves misalignments within methods and between method groups and, in turn, ambiguity around concepts such as scarcity, rarity, criticality and depletion. It follows that long-term scopes need to include assessments of depletion of ecospheric stocks. Methods focusing on factors which represent or can influence magnitude and location of technospheric flows are suitable for short term scopes. Different types of technospheric funds, such as resources in active use, end of life products and landfills, can be relevant in short, medium and long-term scopes. Altogether, assessments of stocks, funds and flows are complementary parts of a comprehensive mineral resource availability assessment.

- Rare Earth Elements (REEs) are one of the most important–albeit critical–commodities for our green technologies. However, there is a general perception that REEs are produced using mining and processing techniques that are unsustainable. Life Cycle Assessment (LCA) is the most widely accepted methodology to evaluate the environmental impacts of rare earth oxide (REO) production. This article aims to provide a synthesis of the currently existing LCA studies on REEs using two strategies. Firstly, an overview of published LCA results of REO production. Secondly, a detailed LCA using the best available life cycle inventories (LCIs) in order to: i). evaluate the state-of-the-art LCI for this sector ii). Understand better the impacts related to each of the three main production routes and iii). Contribute to the development of a preliminary benchmark for the sector. The analysis of the published LCA results reveal that the three main methodological issues with published LCAs are data gaps, allocation, and waste management. The dominating contributor to the global warming potential of the production of REOs in all two of the three routes is chemical extraction and separation.

Sustainability indicator identification and selection for an innovative conceptual system: Phosphorus recovery from dairy wastewater
- 2024

Ingår i: Resources, Conservation and Recycling. - 0921-3449 .- 1879-0658. ; 207

Tidskriftsartikel (refereegranskat)abstract
- In Europe, a decrease in the availability of phosphate rock resources has led to the development of emerging technologies for phosphorus recovery, with the purpose of generating products that can be used as fertilisers. An innovative conceptual system dedicated to the phosphorus recovery from dairy wastewater is considered in the paper. New technologies need to be assessed using relevant sustainability indicators. In this study, we developed an approach for identifying and selecting indicators. Based on searches of literature and expert interviews, three different tools were developed: an indicator screening framework, a questionnaire for finding actor priorities, and a list of indicator selection criteria. The new approach was successfully used to narrow down an initial set of 382 indicators identified in the literature to 26 that were considered representative and practicable for the assessment of the considered system.

Tidskriftsartikel (refereegranskat)abstract
- Supply network collaboration has been recognised as a vital enabler in the transition to a circular economy. Even so, the existing literature has directed limited attention to the nature of these relationships and the motivation behind them. Hence, there is a need to understand the actual activities of actors engaged in collaboration to address this knowledge gap. The steel industry presents an interesting example. Given that more than one-third of the world's steel production originates from scrap, its supply is essential to the survival of the steel industry. Based on an explorative case study, this paper investigates collaboration of steel producers, a procurement intermediary and scrap dealers to facilitate steel recycling. These actors deal with the practical challenge of variation in the quantity and quality of steel scrap by engaging in various types of collaboration. This paper seeks to analyse the nature of these collaborations and answer the question of why actors engage in supply network collaboration. The paper identifies a complex web of relationships and outlines differing motives for and against collaboration, with specific focus on three types. While quality control is the main motive in dyadic vertical collaboration between a buyer and a supplier, efficiency is the main motive for both horizontal collaboration between buyers and lateral collaboration amongst all actors in the supply network. Thus, this paper adds to the conventional wisdom of sequential, dyadic, linear and vertical relationships, providing a deeper understanding of the types of supply network collaboration from the underexplored context of steel recycling.

Consumer preferences for visually sub-optimal food: Role of information framing and personal goals
- 2022

Ingår i: Resources, Conservation and Recycling. - : Elsevier BV. - 0921-3449 .- 1879-0658. ; 184

Tidskriftsartikel (refereegranskat)abstract
- This study investigates how framing in relation to environmental consequences directs consumers to prioritize among gain, hedonic, and normative goals when accepting suboptimal food to reduce food waste. A random sample of 1,704 United States consumers completed a three-wave survey instrument, including repeated discrete choice experiments. Goals related to gains deteriorated substantially over time. Goals for reducing environmental impact by purchasing sub-optimal food were stronger and more time-invariant. There was no increase in goal strength for reduce environmental impact due to the type information provided. Furthermore, there was no support for a lower decrease across time in normative goal strength due to exposure to positive framing. There were combined effects of information and time, respectively. Five latent groups were identified. These results are relevant for actions to increase the acceptance of suboptimal food, finding that differences in consumer preferences are attributable to goal type and goal strength.

How product characteristics can guide measures for resource efficiency - A synthesis of assessment studies

Tidskriftsartikel (refereegranskat)abstract
- A circular economy aims at decoupling value creation from resource throughput. For circular economy to contribute to environmental and resource improvements, there is need for critical assessments regarding in what general situations, beyond individual cases, solutions may lead to improvements. On the product-level, there is need for synthesized knowledge accounting for a wide range of contexts and environmental impacts. We investigate what resource efficiency (RE) measures result in reduced physical flows and environmental impacts, depending on the characteristics of products and their life cycles. The study is limited to physical measures on a product system level, irrespective of manner of implementation. A library of comparative assessments (primarily life cycle assessments and material flow analyses) was built, covering a wide range of products and RE measures. A framework was formulated for analysing for which product characteristics a measure tends to improve RE, and under which contexts there are trade-offs to take into account. For example, sharing of products is best suited for durable and infrequently used products that tend not to reach their full technical lifetime. A trade-off is that sharing can increase transportation for accessing shared stock. The identified key product characteristics were: whether products are consumable or durable, active or passive, typically used for their full technical lifetimes or discarded before being worn out, the product’s frequency of use and whether function remains at a product’s end of use. Pace of development matters for suitability of measures for active, durable products, while complexity is relevant for restorative measures and recycling.
