A major study in Southeast Queensland is testing how quickly biodegradable plastics break down in waterways, as researchers search for solutions to the world's growing plastics problem.

The project is underway at the $13 million Australian Research Council Training Centre for Bioplastics and Biocomposites at The University of Queensland, which has been officially opened by the Deputy Chief Executive Officer of the Australian Research Council, Dr Richard Johnson.

"There is a lot of research on what happens to biodegradable plastic in soil, compost, on land, and in landfills, but we actually don't know what happens when these materials enter the marine environment."

Early results have found PHA plastics which are bioderived, degraded completely in water after 7 months but other bioplastics degraded by a little as one per cent in a year.
