Begoña Galindo, AIMPLAS, indicated that the bio-plastics are expected to grow from 2% of the world market in 2015 to 40% in 2030. She presented the example of fish processing waste: 2 million tonnes/year is generated annually in Europe. Testing in the DAFIA project www.dafia-project.eu (see pinfa Newsletter n°86) has shown that DNA and gelatin recovered from fishery wastes can be an effective flame retardant in polyamide combined with lignosulphonates (UL94-V0, 1.6 mm, at 20% loading). Challenges include higher smoke production than with commercial phosphorus flame retardant, black colour and deterioration of mechanical properties.
