HOUSEHOLDS are still filling about 60 per cent of their red bins with food waste instead of using the new green bins, according to JR Richards operations manager Sean Pleasance.
All organic waste from the green bins is sorted on a concrete floor at the Ophir Road Resource Recovery Centre to remove things that shouldn’t be there before it is fed into a shredder and taken to Euchareena Road to be made into compost.
There was little food waste to be seen during a tour of the $5.5 million recovery centre yesterday.
“Organic waste is vital to the composting process,” Mr Pleasance said.
“We need it to make it meet Australian standards.”
Mr Pleasance said most residents were getting the message about what waste went in what bin, but staff were still seeing minor contamination in the green bins.
“It’s critical we remove the contaminants before it gets to the [compost] tunnels,” Mr Pleasance said.
“Otherwise the whole load could be contaminated from just five kilograms.”
To meet the conditions of the waste project’s approval all inert waste, that will never break down, must be bailed and wrapped in plastic before it is buried at the Euchareena Road landfill.
Processing organic material and making it into compost and compressing inert waste was saving a substantial amount of landfill space, Mr Pleasance said.
