6.2 Biodegradable, fossil-based plastics
Polybutylene succinate (PBS)
- belongs to the polyesters,
- PBS is synthesized by polycondensation of the two monomers succinic acid and 1,4-butanediol
- can be obtained from fossil raw materials, but also from glucose
- is also biodegradable in water
- can be easily processed (printing, welding, production of film)
- Packaging, disposable cutlery, mulch films, composite materials
Polybutylene adipate terephthalate (PBAT)
- Copolymer/ copolyester
- based on 1,4 butanediol, adipic acid and terephthalic acid
- mostly produced from fossil raw materials
- Similar properties to polyethylene
- good elasticity, thermal resistance
- Biodegradable, compostable in industrial plants
- Production of films for packaging, garbage bags, shopping bags or mulch films
- can also be used with starch to make starch blends
