The term "biodegradable" ensures products' reliability in the environment without harmful effects. The ASTM (e.g., ASTM D5511-18 and ASTM D5526-18, American Society for Testing and Materials) defined biodegradable materials as materials that exhibited 70% degradation during 30 days under anaerobic conditions . Under aerobic conditions, ASTM D6400-19 and ASTM D6868-19 require 90% mineralization degradation of the material into CO2 within 180 days . Biodegradable polymers can be synthesized or extracted from different sources (Figure ). They can be obtained from agro-resource biomass (i.e., agro-polymers). They can be extracted from microorganisms. They can be obtained from the conventional synthesis of bio-derived monomers. Petrochemicals are important sources of monomers used for the synthesis of degradable polymers. They can be classified as (Figure ):-(1) Natural-based materials, e.g., polysaccharides (e.g., cellulose, lignin, starch, chitin/chitosan) or proteins (e.g., collagen, Silk fibril (SF)).
