Types of Biodegradable Plastics

Most biodegradable plastics are a fusion of organic materials (cellulose and starch) and chemical compounds that decompose into methane, biomass, water, CO2, and mineral salt. There are two classes of biodegradable plastics namely oxo-biodegradable and hydro-biodegradable. In both, decomposition begins with a chemical procedure followed by a biological procedure. They have their foundations from plant-hydro-biodegradable plastics and petroleum-oxo-biodegradable plastics. Both classes give off carbon dioxide as they decompose; hydro plastic can also give off methane (CH4). 1. Oxo-Biodegradable Plastics Oxo-biodegradable plastics are made by adding a small piece of a fatty acid compound of explicit transition elements to ordinary plastic. The plastic does not emit methane when decomposing, unlike hydro-biodegradable plastic. It is mostly used and recycled alongside traditional plastic. Its products are durable and can last for up to five years and more if kept away from direct...
