Bioplastics and Biobased Adhesives. A new plastics industry buzzword has recently appeared, namely bioplastics. The term is often misunderstood or misapplied, which is understandable as its definition is somewhat flexible. Though only about 1% of plastics production worldwide is bioplastics, their use is growing. They hold the promise of lower environmental impact by encouraging renewable sources of plastic monomers. What Is a Bioplastic Exactly? Bioplastic refers to a family of materials, not a single substance. Essentially, a bioplastic is plastic material derived from plants. It may or may not be biodegradable. A less precise definition would be that it is plastic not derived from petroleum, which most plastics are.
