Are compostable plastics the best option? – AustraliaPosted on September 15, 2023 by DrRossH in Landfills and Disposal
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.
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.
