Environmental impacts of waste management and valorisation pathways for surplus bread in Sweden
- 2020

- Bread waste represents a significant part of food waste in Sweden. At the same time, the return system established between bakeries and retailers enables a flow of bread waste that is not contaminated with other food waste products. This provides an opportunity for alternative valorisation and waste management options, in addition to the most common municipal waste treatment, namely anaerobic digestion and incineration. An attributional life cycle assessment of the management of 1 kg of surplus bread was conducted to assess the relative environmental impacts of alternative and existing waste management options. Eighteen impact categories were assessed using the ReCiPe methodology. The different management options that were investigated for the surplus bread are donation, use as animal feed, beer production, ethanol production, anaerobic digestion, and incineration. These results are also compared to reducing the production of bread by the amount of surplus bread (reduction at the source). The results support a waste hierarchy where reduction at the source has the highest environmental savings, followed by use of surplus bread as animal feed, donation, for beer production and for ethanol production. Anaerobic digestion and incineration offer the lowest environmental savings, particularly in a low-impact energy system. The results suggests that Sweden can make use of the established return system to implement environmentally preferred options for the management of surplus bread.

Aspects Affecting Food Choice in Daily Life as Well as Drivers and Barriers to Engagement with Fungi-Based Food-A Qualitative Perspective
- 2023
-
In: Sustainability. - : MDPI AG. - 2071-1050. ; 15:1
-
Journal article (peer-reviewed)abstract
- Fungi-based food is expected to contribute to more sustainable food systems. The present study has three focus areas: (i) aspects that affect food choices food in daily life, (ii) aspects that affect choices of fungi-based food in particular, and (iii) drivers that motivate, and barriers that prevent, engagement in cultivating fungi and cooking fungi-based food at home. One hundred and sixty participants, who were recruited using convenience sampling, filled out qualitative questionnaires. The results show that there are numerous aspects (e.g., environmental benefits, nutrition, sensory characteristics, production practices and ingredients) that are important when people choose food in daily life. In addition to curiosity, many of these aspects also affect the choice of fungi-based food. The study identified more drivers (e.g., self-providing, curiosity, awareness of ingredients) than barriers (time, knowledge, concerns about contamination) to cultivation and cooking of fungi-based food at home. The findings are relevant for the development of fungi-based food so that this type of food is engaged with, and so that it can contribute to more sustainable food systems.

Household Waste Sorting and Engagement in Everyday Life Occupations After Migration-A Scoping Review
- 2019
-
In: Sustainability. - : MDPI AG. - 2071-1050. ; 11:17
-
Journal article (peer-reviewed)abstract
- The aim of this scoping review was to gain an overview of the current state of the literature on the engagement in waste sorting post migration from an occupational perspective, in the light of two aspects sustainability efforts currently face: Increased human migration and environmental degradation. Both the resource recovery and occupational science literature were reviewed and analyzed. However, despite the current lack on studies on how migrants’ transition into waste sorting schemes at the household level, this scoping review was able to provide a broad picture of the engagement in daily activities that support sustainability, such as household waste sorting. Given the current initiatives to develop efficient resource recovery from waste, such knowledge contributes to efforts to engage households with different cultures and experiences in waste sorting. The results highlight the importance of future research to better understand how people who are new to waste management schemes experience these, and study the way that engagement in waste sorting shifts and transforms. This is because providing such knowledge can contribute to raising awareness of the environmental impact of waste sorting, and inform policies aimed at sustainable waste management.

Design affordance of plastic food packaging for consumer sorting behavior
- 2022
-
In: Resources, Conservation and Recycling. - : Elsevier BV. - 0921-3449 .- 1879-0658. ; 177
-
Journal article (peer-reviewed)abstract
- This research aims to understand why consumers miss-sort plastic food packaging and to what extent the design affordance of packaging can influence consumer sorting behavior. A photo-based observation study and semi-structured interviews were used to gain a deeper understanding of the miss-sorting behavior and how it could be affected by design affordance. This explorative study suggested that the packaging form, size, durability, haptic aspects, and visual communicative properties influence how consumers perceive the value of packaging. This is important, because packaging with low attributed values are not considered worth recycling or correctly sorted and are more likely to be miss-sorted. Hence, a well-afforded food packaging design is expected to improve how consumers perceive the value of packaging and to consequently improve sorting behavior.

A Procedure to Transform Recycling Behavior for Source Separation of Household Waste
- 2016
-
In: Recycling. - : MDPI AG. - 2072-4292 .- 2313-4321. ; 1:1, s. 147-165
-
Journal article (peer-reviewed)abstract
- Household waste separation at the source is a central part of waste management systems in Sweden. Resource recovery of materials and energy increased substantially after separate collection was implemented in the 1990s. A procedure to transform recycling behavior for the sorting of household waste—called the recycling behavior transition (RBT) procedure—was designed and implemented in a waste management system in Sweden. Repeated use of this procedure, which will assist in the continual improvement of household sorting, consists of the following four consecutive steps: (i) evaluating the current sorting behavior; (ii) identifying appropriate interventions; (iii) implementing the interventions, and; (iv) assessing the quantitative effect of the interventions. This procedure follows action research methodology and it is the first time that such a procedure has been developed and implemented for the sorting of household waste. The procedure can easily be adapted to any source separation system (which may have different local situations) and, by improving the source separation, will increase the resource recovery in the waste management system. The RBT procedure, together with its strengths and weaknesses, is discussed in this paper, and its implementation is exemplified by a pilot study done in Sweden.
