It’s time for bioplastics to be plasticsPosted on March 10, 2017 by DrRossH in Plastic Waste News
“I wish people would stop calling PLA* a bioplastic…” said Steve Davies, director of public affairs and communications at NatureWorks during a recent meeting of the Sustainable Packaging Coalition’s Industry Leadership Committee on Bioplastics. “…and start thinking of it as one more functional material—dare I say it…another plastic.”
The world of bioplastics has exploded, and there is an amazing breadth of materials that can be classified as bioplastics. Part of the reason, arguably, is the far-reaching definition of a bioplastic. The most commonly used definition, popularized by European Bioplastics, is that a bioplastic is bio-based, biodegradable or both. To unpack this, that means that a bioplastic can be inherently non-biodegradable. It means that a bioplastic can contain 0% bio-based materials. A bioplastic may be 100% fossil-based. It can be any combination of being partially bio-based, fully bio-based, non-bio-based, biodegradable, compostable or non-biodegradable, so long as it is not both non-bio-based and non-biodegradable.
There are four basic permutations of these characteristics, and bioplastics encompass three of them:
It is correct that the world of Bioplastics has become very confusing and the word is often used to the sellers advantage rather that what the buyer thinks he is getting.
