What are the different types of biodegradable plastics?

There are 2 main types of biodegradable plastics: oxo-biodegradable and hydro-biodegradable. Both first undergo chemical degradation, the former by oxidation and the latter by hydrolysis, resulting in physical disintegration of the plastics and a drastic reduction in molecular weights. In both cases, biodegradation follows with the same end result &#; conversion into carbon dioxide, water and biomass.

In terms of differences, hydro-biodegradable plastics degrade and biodegrade more rapidly, and tend to have much shorter lifespans than oxo-biodegradable plastics. In contrast, oxo-biodegradable plastics are less expensive, possess better mechanical properties and are easier to process and manufacture (as they can be incorporated into standard manufacturing processes without the need for specific manufacturing equipment).

Biodegradable plastics - types and applications

The plastics sector is undergoing a revolution. If there is a clear trend in this industry, it is the search for more sustainable materials for the manufacture of biodegradable products.

Many companies and enterprises have taken up the challenge of reducing the use of conventional plastic and replacing it with more environmentally responsible alternatives. And, although in many applications it is hard to believe that conventional plastic can be replaced, there are many products that could be manufactured in a more eco-friendly way.
