Bioplastic

Common card · No. 246104

Bioplastics (or bio-based plastics) are plastic materials produced from renewable biomass sources rather than petrochemical sources. This definition distinguishes it from biodegradable plastics, which are plastics that degrade by the natural action of microorganisms such as algae or bacteria. In the context of bioeconomy and the circular economy, bioplastics remain topical. The four main classes of bioplastics can be described as such: Natural biopolymers: bioplastics processed from biopolymers with added plasticizers or stabilizers, such as polysaccharides (e.g., corn starch or rice starch, cellulose, chitosan, and alginate) and proteins (e.g., soy protein, gluten, and gelatin) or some forms of lipids (e.g., paraffin, lignin, and acetin) Chemical synthesis: bioplastics chemically synthesized from sugar derivatives (e.g., lactic acid) and lipids (such as vegetable fats and oils) from either plants or animals Microbial synthesis: bioplastics formed from fermentation of sugars or lipids...
