Polymers are used in a range of materials; chemically speaking, they are compounds with molecules bonded together in long, repeating chains. They are often man-made, using petroleum derived, non-renewable resources. Common petrobased polymers include:
13 Bioplastic Innovations That Might Save the Environment - Bioplastic could be the solution to the growing accumulation of hydrocarbon-derived plastics.
Basic Polymer Structure - From Penn State, this source covers the four basic polymer structures and links to information on how different polymers are used.
Bio-based polymers can be direct or "drop in" replacements for petroleum-derived polymers and offer near-identical properties, or they can offer entirely novel characteristics. Some polymers that may include biologic feedstock are TPU, PE, and PLA.
