Bangladesh is a developing country with a massive population of about 160 million. A huge amount of solid waste is being generated on daily basis here in this country. However, due to the lack of proper technology and implementation strategy, most of the generated waste is left untreated or recycled. The circular economy is not a new concept in Bangladesh. People have been practising the concept of circular economy for a long time with their indigenous knowledge and technique. Also, the business is informal in this sector and therefore ignored by the policymakers. This chapter investigated the current practice and future potential of circular economy in Bangladesh, as well as the legal framework to support the operation. First of all, concepts of circular economy and waste-to-energy approach within it have been discussed. Then, strategic and legal aspects of solid waste management in Bangladesh have been summarized. Existing practice of circular economy and waste generation and management scenario have been illustrated from a Bangladeshi perspective. Working principles of refuse derived fuel (RDF) have been discussed alongside the impossibilities of incorporating RDF technology in Bangladesh. Some examples of good practices have been provided as well.
