Bio-plastics: boon or bane
Bioplastics are those types of plastics where carbon is derived from renewable feed stocks. They may be biodegradable or may not be. Basically Bio based plastics are consist of both fossil-fuel-based carbon and renewable. The percentage of bio based ingredients are used is over 70 now a days.
Polymers are studied in the fields of biophysics and macromolecular science, and polymer science (which includes polymer chemistry and polymer physics). Historically, products arising from the linkage of repeating units by covalent chemical bonds have been the primary focus of polymer science; emerging important areas of the science now focus on non-covalent links
Bioplastics are used for disposable items, such as packaging, crockery, cutlery, pots, bowls, and straws. Few commercial applications exist for bioplastics. In principle they could replace many applications for petroleum-derived plastics, however cost and performance remain problematic. As a matter of fact, their usage is favourable only if supported by specific regulations limiting the usage of conventional plastics.
