Beyond the bin: demographic characteristics and attitudes associated with dumpster diving. The UK as a case study

Dumpster diving is the practice of sourcing discarded food from supermarket bins or ‘dumpsters’. The practice of dumpster diving to source food has emerged in a number of affluent countries reflecting systemic inefficiencies in food distribution and waste management that are common across high-income countries. Addressing these issues is critical for achieving global targets such as SDG 2 (Zero Hunger) and SDG 12.3 (halving food waste). This research aims to identify 1) which demographic characteristics are associated with dumpster diving practices, and 2) which attitudes and concerns are associated with dumpster diving practices. The current research analysed data of the Food and You 2 (2023-24), an Official Statistics survey. Using the data from respondents across the UK (n = 5861), a series of binary logistic regression models identified 1) the socio-demographic, socio-economic and geography related characteristics, and the 2) attitudes and concerns associated with dumpster diving practices. We demonstrate that those who have a long-term health condition, children in the household, use food banks or live in urban areas are more likely to have started sourcing food from supermarket bins. Conversely, those who are concerned about food poisoning and being able to eat healthily are less likely to have started dumpster diving. This research provides an evidence base for policy makers to take urgent action in providing increased support and an alternative food source for vulnerable groups. Although this study focuses on the UK, the findings have broader relevance for global food security. • Dumpster diving is a prevalent practice in the UK with 4.7% of adults having started sourcing food from bins or waste areas in the previous 12 months. • Those who have a long-term health condition, children in the household, or use food banks are more likely to have started dumpster diving. • Concern about food poisoning and being able to eat healthily are barriers to dumpster diving. • The prevalence of dumpster diving reflects systemic inefficiencies in food distribution and waste management across high-income countries.
