Terminology –Bioplastics

By Miriam Wilcox-Barsalou,on October 1st,2010%

Bioplastics are often used to describe plastics that are biodegradable,but there are other requirements. The book Green Plastics by E.S. Stevens defines bioplastics as follows:

“Bioplastics is a concise –and suitable –name for biodegradable plastics whose components are derived entirely or almost entirely from renewable raw materials. A bioplastic contains one or more biopolymeric substances as an essential substance.

-E.S. Stevens 2002

Bioplastics may include a combination of biopolymer(s),plastizer(s) and other additive(s). Since this book was written 8 years has elapsed and the definition of bioplastic has evolved and shifted slightly.

Plastics from Renewable Feedstocks

Recently the bioplastics that is most often seen in the press is Poly(lactic) acid,or PLA. It is best known for being made of non-petroleum materials,biodegradable and causing issues with existing waste disposal infrastructure. It is also being used in several bioresorbable medical implants.

In fact a lot of people seem to associate bioplastics with a material that degrades in a reasonable period of time either through biodegradation,oxy-degradation or composting.

However a bioplastic recently being noticed does not degrade. They are essentially traditional plastics made of renewable feedstock. These plastics are 100% recyclable in mainstream recycling their . . . →Read More:Plastics from Renewable Feedstocks
