Strawberry shields forever: bioplastic cuts fruit waste

Strawberries come packaged with a hidden environmental toll in Australia: a lot of clear plastic that does not get recycled. But researchers from the University of Queensland have developed a different way to keep the fruit safe while ensuring biodegradable punnets can return to the farms from which they came.

The co-director of the Centre for Advanced Materials Processing and Manufacturing, Dr Luigi Vandi, partnered with PhD candidate Vincent Mathel to produce the bioplastic material in an effort that has taken three years.

Their environmentally friendly packaging uses biodegradable plastic produced by bacteria and blends it with pine sawdust to give it added durability.

Among the world’s largest plastic consumers, Australians used 3.9 tonnes of plastic in a year and recovered 14.5%, the most recent government statistics show.

When University of Queensland researchers considered developing biodegradable plastic to address the issue, strawberries were a natural focus due to the amount of plastic used to transport them.

“There’s about 125g of strawberries in a punnet and the punnet itself is maybe 12g to 14g, which is quite a lot,” Dr Luigi Vandi told AAP.
