Compostable plastics are becoming more common and can appear to be an intuitive solution to plastic pollution but are they the best option?

COMPOSTABLE PLASTICS CAN NOT BE RECYCLED WITH OTHER PLASTICS

Due to their different composition, compostable plastics cannot be recycled in with other plastics. Their materials have different properties and would contaminate other conventional plastics if they were mixed together. Unfortunately, compostables often well-meaningly find their way into recycling streams, contaminating full batches of recycling and condemning them to landfill.

 

COMPOSTABLE PLASTICS ARE BAD NEWS IN THE ENVIRONMENT

Sadly, a turtle can choke just as easily on a littered compostable plastic bag as a conventional plastic bag.


COMPOSTABLE PLASTICS AND THE CIRCULAR ECOCOMY

The move to a circular economy is about eliminating waste and pollution, and that includes greenhouse gas emissions. A circular economy aims to keep materials in the productive economy and decrease the need for new materials. Any time a compostable plastic item is used once – no matter how it is disposed of – it is still a single-use plastic.

Where possible, we should be choosing products and packaging that can be reused, which will mean less single-use packaging being manufactured and less waste going to landfill or litter.
