New materials? Before 1940 approx . 80 % of monetarily accessible biodegradable plastic and its monomers were found and portrayed 1938 Polyethylen In the 70s: Oil emergencies (1973) Set point for further improvement In the 80s: Oil emergencies (1980) – pilot plants for bioplastics Oxodegrable items – repressed the further advancement ?
