Experts react to single-use plastic ban

A senate inquiry into Australia’s recycling industry has recommended that all single-use plastics should be banned by 2023.

The decision could potentially include products like takeaway coffee cups, chip packets and takeaway containers.

Professor Sankar Bhattacharya from Monash University’s Department of Chemical Engineering said time is of the essence to find a new home for recyclate stockpiles.

“Now that China has stopped taking our trash, we’re scrambling to figure out how to keep all those good intentions out of the landfill,” he said.

“The majority of the plastics we use in our daily life – different grades of polyethylene, polypropylene, polystyrene and even polyvinyl chloride, to some extent – can be processed into liquid fuel.

“That’s what China was doing with the plastic recyclables it bought from us. They’re now realising that their domestic production of waste products is so large that they cannot process any more by bringing in waste plastics from other countries,” he said.

Katherine Gaschk, a Research Masters from Murdoch University said she was pleased with the Senate inquiry’s findings.

“The sooner we accept the need to stop using plastics and change from our current mode as a throw-away society, the better for the future health of our planet,” she said.

“Ultimately it is human behaviour that is responsible for plastic pollution. Removing the plastics will certainly help to reduce pollution, but there is also a need to educate retailers, consumers and manufacturers about the impacts of plastic pollution and how we can reduce our dependence on plastics.”

Simon Lockrey, a Research Fellow from RMIT University’s School of Design warns that while the ban would be great in theory, there may be rebound effects.

“For instance in food systems, packaging can save food waste in the supply chain, from farm to plate,” he said.

“Without acknowledging other changes to that system when taking away single-use packaging, we may move the waste burden, sometimes to more impactful levels. For example, packaging can be a low impact compared to food waste impacts.

“Therefore, it would be good with this senate initiative to see the complimentary strategies for industries using single-use packaging to make sure we are in a waste reduction winner all around,” Mr Lockrey said.

Thavamani Palanisami, a Senior Research Fellow at the University of Newcastle’s Global Centre for Environmental Remediation said what should be the next step.

“Tags such as ‘biodegradable’, ‘bio-based’, ‘100 per cent degradable’ need to be regulated,” he said.

“We need to create public awareness about types of plastic and their individual behaviour.

“We need to set standard testing methods to verify the biodegradability of the plastic items tagged as ‘biodegradable’,” Dr Palanisami said.
