Bioplastic producer Cereplast says it has developed biodegradable, compostable plastics that can withstand freezing temperatures as low as -35 degree Celsius.
Standard polylactic acid (PLA)-based bioplastics can only withstand up to about 20 degree Celsius, says the company. The plastic can be ideal for frozen food applications such as ice cream containers.
With these fast developments, pretty soon bioplastics will be a standard material in our everyday lives. But maybe they have to come up first with alternative feedstock that does not compete with food.
