Terry Ditton and his parents, Denise and Christopher, who are joint owners of Anambah quarry, will open the new facility on the quarry site on Monday, March 23.

"This has been in the pipeline and under construction for five years," Terry said.

"At the moment people in the west have no option but to take it to the tip which is a fair distance to travel, especially with a trailer full of wood waste, trees or stumps," he said. "We believe the western side of the city has been crying out for this."

The privately owned facility - named the Riverbend Organic Composting Facility - will sit inside the quarry, although the quarry operation will continue unchanged.

The Dittons say the idea for the waste facility was triggered by the amount of money they were spending on compost to mix through their quarry material.

"That was what sparked the idea," Denis said. "We thought we already have the space here for it, we're spending a lot of money on compost anyway, so why not build it ourselves and then sell the compost we make."

Like Maitland tip, those interested in using the facility will drive over a weigh bridge, have their load weighed, and then pay on the way out.

"We're starting off with an introduction special of $90 a tonne plus GST," Terry said.

He said the site was expensive to build as it required sophisticated technology.

"It's all computer controlled. The green waste has to be covered with a special membrane to keep the nasties in, then it has to be pasteurised and certified before it can be sold as compost."
