Over the past decade, Thailand’s waste management system has undergone significant transformations. Despite these changes, the country continues to grapple with various challenges, including limited public participation, inadequate institutional support, and low investment in the sector. Nonthaburi Municipality was chosen as the focus of the study due to the significant challenges it faces in municipal solid waste management (MSWM) stemming from population growth, migration, rapid urbanization, and economic expansion.

The manual aims to support both formal and informal recycling enterprises in preventing plastic pollution by advocating best practices and promoting proper housekeeping within informal recycling facilities, based on insights drawn from Nonthaburi Municipality.

This manual is published by the Regional Resource Centre for Asia and the Pacific (RRC.AP) of the Asian Institute of Technology (AIT) with support from ERIA's Regional Knowledge Centre for Marine Plastic Debris under the project "Development and Dissemination of Technical Guidelines for Plastics and Resin Pellets Leakage Prevention from Factories and Informal Recycling Sector in the ASEAN".
