Degradable, biodegradable and compostable plastic bags may not be any better for the environment than standard plastic bags. Also, these bags do not necessarily reduce the use of plastics and are made with combinations of plant and/or synthetic plastic material.
The Victorian Government’s three-month public consultation in 2017–18 on our approach to banning plastic shopping bags attracted an overwhelming response of more than 8,000 submissions. Two thirds of respondents supported including biodegradable, degradable and compostable shopping bags in the ban. Submissions noted that there is much confusion around whether these bags are more environmentally friendly than typical plastic bags.
