Extending the useful life of consumer products is a critical element in the circular economy. Although commercial repair is an established part of the global economy, the repair is often conducted informally. This means that non-commercial repair ecosystems exist, including the international network of repair cafés, spreading worldwide to over 2000 repair cafés in 37 countries (April 2021). As the first review on this topic, this article investigates and gains more knowledge about repair cafés, and critically assesses their role as a sustainability initiative, i.e., how the concept may translate into a broader sustainability context. A systematic literature review (2010–2020) was conducted, including 44 articles in descriptive and content analyses. The bibliometric data revealed an increase in the number of publications on repair cafés, particularly over the last four years, indicating that repair cafés as a research topic have started to gain attention, and this is likely to grow in numbers. However, the significant number of different places of publication indicates that this is not (yet) a well-established field with defined research channels. The content analysis revealed that the concept has spread to a range of different contexts, beyond the original scope, influencing the mindset and acts of a broad field of practitioners. This indicates a wide range of possibilities for the expansion of the concept of repair cafés, bringing different expectations on calling into question the future role of repair cafés. However, the aims of the people involved in repair cafés span from the altruistic and strategic, over personal gains, to critical consumer, financial and educational aims. This may challenge repair cafés’ future role(s), i.e., ambitions set by the international organisation of repair cafés. Notably, the ambition for actors at the micro-level is to feed in data on repair and achieve ‘collaborative repair’, as the aims of the people involved are complex, and their expectations lack alignment, both vertically and horizontally.

A circular economy (CE) aims to reduce waste and encourages keeping products, components, and materials circulating in the economy. Furthermore, following the European waste hierarchy, preparing for re-use (PfR) is regarded as a better waste management option than recycling. Nevertheless, too many products with a reuse potential end up as waste. This includes residuals from products that have no major value and are therefore not demanded by the current system. As a result, products are prematurely recycled. This contradicts both the priority order of the waste hierarchy and the principles of a CE. This article investigates the potential of and constraints to reusing products that are disposed of at municipal recycling stations. It aims to improve our understanding of these issues and offers possible solutions that could enable municipal waste companies to transition from waste to resource management and reach the upper levels of the waste hierarchy, preparing waste for re-use. Interviews with relevant stakeholders, desk studies and knowledge obtained from participating in waste conferences over the past 3 years are all used to analyze PfR practice at five municipal waste management companies in Denmark. Pioneers with respect to circularity in the waste sector, which have been experimenting with and initiating PfR schemes concerning a range of products, including building materials, furniture, white goods and bicycles, are considered because they support the inner cycles of the CE. However, results reveal that the current transition consists of complex processes connected to an ambivalent legal framework and struggles over access and rights to resources. Further, a more coherent conceptual understanding of PfR is needed as the current understanding has a too narrow focus on restoring product value rather than coupling PfR processes to the market. Thus, challenges to achieving higher PfR rates seem to go beyond engaging in strategic partnerships, creating financial incentives and setting separate targets for PfR. Consequently, a more holistic investigation appears to be necessary to deepen our understanding of processes of resource management and use and the contestation that exists over these. Furthermore, a wider mapping of the actors operating in the tension area of PfR, including their willingness to cooperate and negotiate a zone of agreement, could prove beneficial to practitioners and policy developers alike.

Concrete is the most commonly used material worldwide, often associated with an irreversible production process and waste generation at the end-of-life. As such, the concrete industry holds large untapped potentials for moving towards more circular economy (CE) practices. Product service system (PSS) offerings incentivize CE through extending product use, improving product performance and developing responsible end-of-life and take-back strategies. A broader definition of the concept of PSS is suggested, and a conceptual framework for realizing CE at the ‘product’, ‘service’ and ‘system’ dimensions is provided. The framework is applied to the case of concrete industry in Denmark. The aim was to cast new light on how the concrete industry can realize CE through a broader ‘product’, as well as ‘service’ and ‘system’ perspective. The selected case is analyzed through nine semi-structured interviews, additional secondary data, and follow-up dialogue with selected stakeholders. Results indicate a ‘product’ perspective may lead to savings on input material cost, improved efficiency of resource use, and reduced concrete waste quantities. A ‘service’ perspective can bring new market opportunities for concrete producers to adapt solutions to users’ needs. A ‘system’ focus calls for new forms of organization and collaboration, as well as the expansion of networks within and across different stakeholder groups.

The circular economy (CE) gives rise to paradigm shifts in the understanding, practice and regulation of waste, challenging a waste sector built for the linear waste paradigm of waste streams rather than value streams. We examine how a waste management company developed value streams, caught between increasing competition for waste types with high market value, and rigid regulation limiting the development of new streams. This cross-pressure necessitates new knowledge and practices to not only transform waste streams into value streams, but also to prioritize the inner circles prescribed by the CE paradigm. There is a potential for increasing reuse of products that have been collected as waste or handed in at municipal recycling stations. However, if the product value is not sufficient to be attractive for the existing market, then the value must be added, and a market must be created. There is a great deal still to learn about what it takes to create value out of waste products and what the role of municipal waste companies is in that process. Our findings indicate that unlocking the potential of waste (in this case, old bricks and waste electrical and electronic equipment) has been far from straightforward. Value must be created through several activities, requiring collaboration between a range of actors as well as new knowledge and business competencies. This contribution aims to open discussion on what it takes for waste management companies to navigate the new complexities in the transition from waste to resource management.

This article argues that participatory approaches are essential for transitioning the waste sector from a linear to a circular paradigm. This transition involves reinterpreting waste as a resource and emphasises critical strategies for waste prevention and reduction of use – a shift that calls for real-life examples involving local communities in waste management. The article unfolds exemplary cases from Southeast Asian and Scandinavia to understand how new participatory cases in waste management are established, anchored and supported. To facilitate such waste management innovation, the article introduces theories on participation and empowerment, explores various participatory approaches to empowering stakeholders in the waste sector, and discusses the possibilities for and constraints on citizen and stakeholder participation in waste management. The findings indicate that empowerment – encompassing values such as care, respect, critical thinking and local resource control – introduces a sustainability dimension to waste management, sparking potential for future advancements. The cases examined illustrate the pivotal role that universities and public sector waste companies can assume in promoting dynamic circular pilot projects at the local level. The flexibility of local governance structures appears to play a significant role in the cases explored, underscoring the need to balance local adaptability and national frameworks to foster meaningful progress towards circular waste management practices. Future studies could explore how critical strategies focused on waste prevention and reduction of use can reinforce the transition towards interpreting waste as a resource.
