In Australia, growing environmental concerns have driven a surge in bioplastics, but unclear labelling for disposal is creating challenges, according to a new report from Australia’s national science agency, CSIRO. The State of bioplastics in Australia report found consumer confusion over bioplastics, with many bioplastic items ending up in landfill or contaminating recycling and composting streams.
Plastics derived from fossil fuels account for 3 per cent of greenhouse gases. With global plastic production currently sitting at 460 million metric tons and estimated to double by 2040, demand for sustainable and bio-based alternatives is increasing.
The uptake of bioplastics is currently limited by high production costs, with most bioplastics in Australia imported from Thailand and Brazil.
“Bioplastics make up only 1 per cent of plastic used in Australia which provides a significant opportunity to create commercial opportunities, while reducing impacts on the environment,” said Dr Albert Ardevol, CSIRO’s Plastic Packaging Research Lead.
“Polylactic acid (PLA) is predominantly used in Australia for packaging but the majority ends up in landfill, which highlights the need for improved waste management and recycling infrastructure.
