Every year JR Richards supplies Dubbo Regional Council with 1200 tonnes of compost at a heavily discounted rate that's created from the food organics and garden organics that goes into the green bins.

The green waste from Dubbo, Mid-Western and Narromine councils is sent to the Dubbo Regional Organics Processing Plant and turned into organically certified compost.

Council's acting manager of open space Wes Giddings said it was used on the Lady Cutler Ovals, South Dubbo Ovals and Victoria Park No. 2 and 3 Ovals.

"The compost will enhance the turf quality and improve the makeup of the soil, improving the playing surfaces of our fields," Mr Giddings said.

JR Richards facilities manager Mark Darwin said the compost was sold to businesses across Dubbo, but also as far as Albury-Wodonga. Being organically certified, Mr Darwin said it was well sought after to help put carbon back into the soil.

It's why what residents put into their organic waste bin is so important.

"We'd love to see people put more food waste in the green bin. People are still putting it in the red bin and when it goes to landfill it generates a lot of methane. Whereas when we go through our process we turn it into something that can be reused. It's really important to put the good waste in the green-lidded bin," Mr Darwin said.

"We need the nitrogen as well. Food waste brings us a lot of properties we can't get just out of trimmings, especially in drought when a lot of the green waste that comes in is quite dry. Food waste helps with that immensely."

Contamination is also a struggle.

Mr Darwin said it was an ongoing process to educate residents about the right bin for their rubbish. He said a common issue was people who throw their general waste into the organics bin because their general waste bin is full.

"If we see contamination we can press a button inside the truck and that will actually take a photo and record where it was taken from. Then we can send a letter to residents explaining that they've had contamination in there and educate them on what they can and can't put in the bins," Mr Darwin said.

It takes only four months from when the bin is collected until it can be sold as compost to businesses like council.

"It's a good opportunity to return that waste back to the residents. You turn that waste that could have gone to landfill into something that will help grow the grass for kids to play on," Mr Darwin said.
