Abstract: Urban food waste issues in developing economies have recently attracted the attention of policymakers, practitioners, and academics in the course of implementing the Paris Agreement and the SDGs. In our case study city of Bangkok, Thailand, household food waste generation doubled from 2003 to 2018, with a similar increase in per capita amounts. Using an extensive literature review, statistical models, and a questionnaire survey, the authors clarified factors influencing food waste generation and separation before disposal, and reuse/recycling activity in urban households. Results showed that pre-purchase checks can not only prevent food waste but can also increase the reuse/recycling of food waste. Citizens with higher levels of education and those showing more concern about social issues and global warming are more likely to separate food waste before disposal and to participate in reuse/recycling activities. Finally, this paper proposes a seven-stage action-based model of integrated strategies for improving household food and food waste management to prevent/reduce food waste generation as well as remedy existing policy gaps in Bangkok.
