This handbook features best practices for integrating waste to energy and related technologies into the operations of various industries in developing Asia. It discusses current technologies, presents a conceptual example of municipal solid waste planning, and provides commentary on waste-to-energy initiatives. The importance of appropriate infrastructure as well as flexibility and openness to technologies and business models is emphasized. The handbook—and its complementary compendium of 18 projects—aim to support the efforts of developing countries in Asia and the Pacific to deploy and scale up technologies relevant to the circular economy.
