Kerbside Waste Audit 2014

The 3 Bins and a Basket kerbside service is a significant investment for Council that has the potential for important economic and environmental returns. How great these returns are will largely depend on the actions of residents.

Kerbside Waste Audits

In May 2014, KESAB Environmental Solutions was engaged by the City of Burnside to undertake a follow-up Kerbside Waste Audit in order to identify how our City has progressed since the implementation of our 3 bin system in December 2012 and initial Kerbside Waste Audit in June 2013.

Per the previous audit conducted by KESAB Environmental Solutions in June 2013, three hundred randomly selected red, yellow and green lid bins were audited across the City. The results of our second audit were truly outstanding, and residents should be extremely proud of their switch from the split bin to the three bin system.

Burnside residents have further increased our diversion of household waste from landfill from 60% to 62.5% (the June 2013 audit identified an increase in diversion rates from 46% to 60% following our switch to the 3 bin system). This years' diversion rate is one of the highest in the nation, and is one that this Community should be very proud of.

The amount of contamination in the yellow lid (reuse/recyle) bin continues to negatively influence our ongoing attempts to reduce waste to landfill, with the number of recyclabe products placed in plastic shopping bags prior to being placed into the recycle bin. This year's contamination rate was dramatically influenced by the careless disposal of nearly 30kg of Copper Sulphate in hessian bags. Not only is this inappropriate for a recycle waste stream, it also presents numerous environemental and safety risks.  The Community is reminded that rinsing/wiping out recyclable containers prior to placing these into your recycle bin will further assist in reducing our contamination rate into the future.

This most recent audit demonstrated again that we need to:

  • get more food waste out of our red lid bin and put it into the green lid bin; and
  • stop putting our recyclables in plastic bags and into the yellow lid bin – recyclable items should be placed loose into the recycling bin.

Of the 7.7kg of waste generated on average per household per week and placed into the red lid (waste to landfill) bin, over half of this waste (3.6kg) was in fact food and therefore could be directed to your green organics bin.  Further to this, of 7.7kg of waste generated on average per household per week, only 2.7kg of materials CANNOT be diverted from landfill - this means that 5kg per household per week of recyclables and organic materials are being placed into the waste to landfill bin.  More can be done without too much effort.

Environmentalist Jon Dee has launched a website to motivate householders to save money, reduce food waste and share great recipes among family and friends. Contributors include Gardening Australia host Costa Georgiadas and South Australia’s own Maggie Beer.

Australians waste about 4 million tonnes of food a year, and that’s a conservative estimate”, says Jon. “A lot of people think food waste is benign, that it just rots gently in the ground. It generates methane, one of the worst greenhouse gases, at least 20 times worse than carbon dioxide. We’re wasting huge amounts of resources and energy".
