Biodegradable plastic. Biodegradable plastics are plastics that can be decomposed by the action of living organisms, usually microbes, into water, carbon dioxide, and biomass. [1] Biodegradable plastics are commonly produced with renewable raw materials, micro-organisms, petrochemicals, or combinations of all three. [2]
Bioplastic. Biodegradable plastic utensils. Flower wrapping made of PLA-blend bio-flex. Bioplastics are plastic materials produced from renewable biomass sources, such as vegetable fats and oils, corn starch and rice starch, [1] straw, woodchips, sawdust, recycled food waste, etc. Some bioplastics are obtained by processing directly from ...
Biodegradable polymers are a special class of polymer that breaks down after its intended purpose by bacterial decomposition process to result in natural byproducts such as gases (CO 2, N 2), water, biomass, and inorganic salts. [1][2] These polymers are found both naturally and synthetically made, and largely consist of ester, amide, and ether ...
Biodegradable plastic bags are nowadays as strong and reliable as traditional (mostly polyethylene)-bags. Many bags are also made from paper, organic materials like Manila hemp, or polycaprolactone. [2][3][4] A single use compostable bag from a grocery store. A tote bag made of Manilla hemp, produced by the Swiss bag company QWSTION.
Biodegradation is the breakdown of organic matter by microorganisms, such as bacteria and fungi. [a][2] It is generally assumed to be a natural process, which differentiates it from composting. Composting is a human-driven process in which biodegradation occurs under a specific set of circumstances. The process of biodegradation is threefold ...
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be molded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being lightweight, durable, flexible, and inexpensive ...

Polymer degradation. Polymer degradation is the reduction in the physical properties of a polymer, such as strength, caused by changes in its chemical composition. Polymers and particularly plastics are subject to degradation at all stages of their product life cycle, including during their initial processing, use, disposal into the environment ...
