daily upated news at News ABA requests compostable bags into bag ban discussions The Australasian Bioplastics Association (ABA) has called for support of certified compostable bags as an alternative to single use lightweight plastic bags. The ABA welcomes discussions and the recent Australian Ministerial Roundtable regarding more states banning single use conventional polyethylene plastic bags. With South Australia, the ACT, Northern Territory and Tasmania having already banned lightweight plastic bags, New South Wales, Victoria and Queensland are currently discussing their options. South Australia, the Northern Territory, the ACT and Tasmania did not ban certified compostable shopping bags. The ABA supports bans on conventional plastic bags. Conventional polyethylene plastic bags may seem useful for shopping and the like, but they are not compostable, not biodegradable, are rarely recycled at end of life, instead ending up in landfill or as unsightly litter. In a similar call to the one made by the Australian Organics Recycling Association (AORA), the ABA is requesting to have certified compostable bags exempted from a ban on conventional polyethylene plastic bags. In Australia approximately 14 million tonnes of organic waste is generated annually of which significant amount is food waste. Organic waste is the second largest volume of waste generated by industry and households. Diverting organic waste from landfills in Australia represents an immense opportunity. Used as a convenient way to capture food waste, certified compostable bags can be disposed into green waste bins and sent to composting. Certified compostable bags are digested by microorganisms in the compost, in exactly the same way as food waste. The compost can be used to improve agricultural soil quality by returning carbon and other nutrients back into the soil. Australian soils are generally carbon deficient and adding compost to these soils, solves several problems at the same time-diverting food waste from landfill, emission reduction associated with reducing organic content in landfills and improved agricultural soils with increased organic content. Rowan Williams, President of the ABA explains, “Certified compostable means compostable and biodegradable. Collecting food waste in the home in conventional plastic bags condemns the contents and the bag to landfill. Source separation of the food waste into certified compostable bags will allow the local council, processor or organics recycler to know that the bag can safely pass through their operation without having to be diverted to landfill. The bag and its contents will completely disappear in a composting environment, within the composting process cycle. Conventional polyethylene bags, no matter what additives are used which are claimed to cause biodegradation, will never achieve the required performance of these standards. Be safe, be sure, be certified.” It is important to understand that oxo-degradable, biodegradable and certified compostable are not the same thing. Unless bags are Australian Standard AS 4736-2006 certified compostable or Australian Standard AS 5810-2010 certified compostable they are not considered suitable for use in organics recycling. The ABA performs verification of claims made by individuals and companies that wish to have their claims of compostable and biodegradable products, verified.
