Purpose: Food waste is acknowledged as a major environmental issue, but the retail sector has only begun to recognise this in recent years. The purpose of this paper is to answer when, how and why food waste became important for retail in Sweden.Design/methodology/approach: A mixed-methods approach was used that included a literature review, quantitative data from retail, field studies, 11 interviews and a media study consisting of newspaper articles spanning 10 years. The combined methods provided qualitative rigor and saturation.Findings: Results show that the increased interest in the issue stems from several factors working together. These factors include the availability of data, the formation of actor networks working together, increased societal environmental awareness, attitude change amongst consumers and retail, and the role of media as an actor and a method for making the issue visible. In addition, results show how the issue surfaced further, as more data became available. Findings suggest that food waste became an environmental issue, and later, the focus shifted to finding solutions for retail.Originality/value: The results highlight the importance for policy to implement preventive measures and strengthen incentives for retail to work with reducing food waste. Such incentives should target cheap food, education, routines, legislation and business models throughout the food chain.

Today, considerable amounts of resources are landfilled or incinerated, and recyclable materials such as metal, glass, plastic, and paper are disposed of as residual waste instead of being sorted into recyclable fractions. Recycling is one way of transitioning towards a circular economy and a more resource-efficient society. However, in many older cities there is insufficient space for waste bins, which makes waste sorting difficult. The aim of the study was to test how the introduction of a new kerbside collection system, using different-coloured plastic bags, would influence the amounts of residual waste and separately collected food waste. Coloured plastic bags were introduced in an old city centre in Kalmar, in the southeast of Sweden. This type of kerbside collection was applied to 38 apartments with a total of 87 residents for four weeks. Results show that residual waste decreased directly by 15 percent and the collected amount of food waste increased directly by 35 percent. The residents perceived that the sorting system facilitated sorting and that the sorting of recyclable materials increased. Kerbside collection, close to properties, seemed to be an important factor in reducing the amount of residual waste, leading to increased sorting, and hence improved recycling.

For a recycling system to work, both stakeholders and households need to feel engaged in the process. When studying engagement in the context of recycling, it is clear that a broader view is necessary to understand the opportunities and limitations that exist among stakeholders and users. Service dominant logic is undertaken to shed new light on how stakeholders, with the household as a focal point, engage with each other in the service ecosystem. Thematic network analysis was employed using interviews with households, stakeholders, as well as workshops in a project about recycling. The analysis reveals four mechanisms (channeling information, managing different resources, understanding impact, and dynamic and time-related engagement). There are several goals and values present when stakeholders and households engage with each other. When values of different actors align, it provides a solid basis for collaboration. Engagement was also found to be time-related and linked to calculated or perceived future effects, but also required to be maintained with the integration of different resources (e.g. money, space, time, cognitive, emotional, bodily energy). In the short-term perspective, utilitarian (functional) values such as the function of the recycling house emerged essential, while the long-term perspectives included feelings about the environment or one's own contribution. Implications for waste management include the importance of recognizing the relation between, and the involvement of stakeholders and households, as well as understanding how these interact to optimize recycling systems.

Funding agencies and policy-makers have put increasing pressure on scientists to better clarify the usefulness of their research. It has been suggested that this may have led to an increased reflection on the societal relevance of research among the scientists themselves. However, this often is more an assumption than a carefully verified fact. This paper investigates whether reflection on societal relevance actually occurs and has a measurable effect on the choice of research and on dissemination activities performed by scientists. A survey was conducted among researchers in environmental science and technology at Swedish universities. Results show that researchers do frequently reflect upon the societal and environmental relevance of their work. We used path modelling techniques to assess how this influences their professional activities. Results show that reflection was important to explain both the choice of research and dissemination activities. Variables such as individual attitudes, experience and collaboration with external actors also affected these outcomes.
