Synthetic polymers with their non-renewable nature cause serious environmental problems. The limited availability of raw materials and the non-degradable nature of such synthetic polymers limit their use in purposes such as food packaging, thermal insulation, etc. Therefore, Scientists around the world have focused on the development of "green foams" with unique properties for the production of various functional materials. Natural fibers are widely used as a reinforcing material in thermosets due to their low cost, abundance and special properties. And thermoplastics are used. In addition, these materials have positive environmental benefits and favorable recyclability. If these materials are supposed to be increasingly sustainable and help to reduce the negative effects caused by plastic waste, we must solve the challenges in their production and use.This study focuses on recent developments in biodegradable foams, synthetic processes adapted to produce foams such as extrusion, baking, etc., properties and applications of various types of foams including starch and cellulose based foams and their polymer blends, challenges in the development of bioplastics, pathways New to obtain bioplastics, progress in the bioplastics industry and social allocation for these plastics are discussed.
