Household Food Waste Practices Through the Lens of Social Practice Theory: A Theory-based Review

This theory-based review explores the application of the social practice theory in household food waste behaviour research using a combination of PRISMA, POWER and TCCM frameworks. Drawing on 40 high-quality peer-reviewed articles, the review offers a new classification of household food waste practices based on their nature, interrelatedness as well as how past research uncovered key elements of household food waste as social practices. This is the first article to conceptualize the continuum of interrelatedness (bundle, compound and complex of practices) and advocates for a shift from individualistic behavioural models to more complex perspectives to reflect shared household practices. The article proposes future research to focus on underexplored areas in theoretical frameworks, elements and contexts of social practice theory, contexts and methodologies.
