Food waste figures swell

Nine million kilograms (9000 tonnes) of food scraps have been collected and kept out of landfill as a result of the rollout of more than 440,000 food scrap bins across Auckland over the past seven months.

Warkworth and other urban areas in Rodney – although not Wellsford or Matakana – were among the last to receive their bins, with collections beginning last month.

Some areas have seen reductions in the weight of total refuse in kerbside rubbish bins by up to 20 per cent.

“Our aspiration for Auckland to become a zero-waste city by 2040 is much closer, with most residents now able to access the food scrap collection service,” Auckland Council planning, environment and parks committee chair Richard Hills said.

“Weekly amounts collected right now suggest we’re on track to collect over 35,000 tonnes in the first full year, well on the way to our yearly target of 40,000 tonnes.”

The scraps are trucked to a plant in the Waikato where a process called anaerobic digestion technology breaks them down into biogas and nutrient liquid fertiliser.
