Arecent Mount Gambier kerbside bin audit identified that more than half the general waste stream could be diverted away from landfill with food organics making up 27% of the average residential general waste bin.
The audit was undertaken by Rawtec and Dynamic 3E on behalf of the Mount Gambier City Council.
Council’s Environmental Sustainability Officer Aaron Izzard said residential waste was audited from a representative sample of the community across the three bin system including general waste, recycling and food organics/garden organics (FOGO) with results indicating contamination in all kerbside streams was above reasonable levels.
“In the 2016 audit food organics made up 36%, so while we are making good progress, 27% is still very high and equates to more than 1500 tonnes of food waste from Mount Gambier households going to landfill every year,” he said.
“We implore residents not to put their food waste in the general waste bin, but instead purchase a FOGO bin for a one-off fee of $85 or take advantage of discounts on composting gear through council’s partnership with Compost Revolution and start composting food scraps at home.
“Everyone can do their bit to help the environment and reduce the cost to the community – food waste should not be going in the general waste bin as all food waste – even bones, meat, dairy etc can go in the organics bin.”
Mr Izzard said the audit highlighted that on average residents generate 14.9kg of waste per household per week, while 30% of the contents of the average general waste bin could be placed in the recycling bin.
“Each household has a recycling bin with fortnightly collection and this result highlights a need for the community to better separate their waste and make proper use of the recycling bin system,” Mr Izzard said.
“The sample showed a contamination rate in the recycling stream of more than 22% with the most common contaminants including general waste, large e-waste, textiles and soft plastics.”
Mr Izzard said the composition of the FOGO recycling stream was identified as predominantly garden organics with a contamination rate of 3.4%. Of this, 2.8% was general waste either loose or in plastic bags.
“It is pleasing to see a low contamination rate in the FOGO bin, and this may be a result of the current opt-in system, however any amount of contamination makes the recycling and organics systems more expensive and less viable,” he said.
“Every little bit counts so we encourage all residents to choose the right bin, do not just throw it in.”
Mr Izzard said the audit results will be used to inform council’s waste services and education activities.
“Council will now continue to explore opportunities to increase education and communication around effective recycling and landfill reduction,” he said.
“Households are encouraged to access existing resources to assist in better understanding the most impactful actions thwat can be taken to reduce their waste footprint.
“Residents can obtain a copy of council’s ‘What to Recycle Where’ guide from the City of Mount Gambier website to better understand how to divert household waste away from landfill.
“There are also a number of educational videos on the City of Mount Gambier Facebook page and YouTube channel which help to identify which waste stream certain items should go in, and the ‘My Local Services’ app is a useful tool where residents can get bin notifications, work out what to put in which bin, and even report issues such as broken bins or damaged council infrastructure.”
