The grumpy bin:reducing food waste through playful social interactions

Domestic food waste is a world-wide problem that is complex and difficult to tackle as it touches diverse habits and social behaviors. This paper introduces the Grumpy Bin, a smart food waste bin designed for the context of student housing. The Grumpy Bin1 contributes to the state of the art of food waste prevention solutions by challenging the traditional approach on pervasive technology, which is commonly based on system-driven judgements and persuasive data representations. Instead, this design empowers users and their social acquaintances to collectively judge their actions, hence adding a layer of social mediation that is likely to increase the chance for behavior change.</p

Scale-Score: Investigation of a Meta yet Multi-level Label to Support Nutritious and Sustainable Food Choices When Online Grocery Shopping

Food consumption is one of the biggest contributors to climate change. However, online grocery shoppers often lack the time, motivation, or knowledge to contemplate a food's environmental impact. At the same time, they are concerned with their own well-being. To empower grocery shoppers in making nutritionally and environmentally informed decisions, we investigate the efficacy of the Scale-Score, a label combining nutritional and environmental information to highlight a product's benefit to both the consumer's and the planet's health, without obscuring either information. We conducted an online survey to understand user needs and requirements regarding a joint food label, we developed an open-source mock online grocery environment, and assessed label efficacy. We find that the Scale-Score supports nutritious purchases, yet needs improving regarding sustainability support. Our research shows first insights into design considerations and performance of a combined yet disjoint food label, potentially altering the label design space.Comment: Work in progress. arXiv admin note: text overlap with arXiv:2309.0323

Municipal Collection and Sorting Mechanisms: lifecycle pathway for recycled plastics

This report focuses on many of the processes plastic goes through from the point a consumer decides to recycle it until it is available for reuse in an IEM or AM facility. This includes the pre-sorting by consumers, kerbside collection, and the sorting mechanisms at different stages in the plastic waste recycling system

Social recipe recommendation to reduce food waste

Little attention has been given to food waste prevention in households by changing consumers' behaviors. In this paper, we present a social recipe recommender which is a mobile application being developed to reduce food waste in households by recommending recipes to a group of connected people. The application will allow the logging of food and waste related daily practices and will persuade a group of users to share their food by recommending recipes based on available ingredients within this group. The method of data collection, persuasion and the experiments are described through this paper
