Biopolymers are compounds made by all living organisms, including plants. Polymers are made of repeated units of the same or similar structure (monomers) linked together. Rubber, starch, cellulose, proteins and DNA are examples of natural polymers or biopolymers. By combining different biopolymers, materials of highly specialised or even novel properties can be made. These bio-based materials can be used to replace oil derived polymers such as plastics, for example PVC (Polyvinyl chloride) which is one of the most commonly used plastics.
Examples for uses of biopolymers:
- Alternative sources of natural rubber with beneficial characteristics
- Starch (in combination with other materials) can be converted into a plastic material that is used to make biodegradable bags, pots and foams.
A large number of restricted substances can be found in consumer products which are biopolymer based. In particular,a number of chemicals under REACH regulation, such as lead; cadmium, formaldehyde and mercury.
