UPDATE: The enhanced soil resulting from a mix of human waste and crushed green waste will benefit the whole region, the director of a waste management company says.
C-Wise director Andy Gulliver said it would help a whole range of users in the community, from farmers to parks and gardens to home gardeners, to build healthy soils.
"When waste goes to landfill they generate methane and nitrous oxides which are important greenhouse gases," he said.
"By recycling those wastes we actually generate beneficial uses for those wastes."
EARLIER: A trial mixing human waste with crushed green waste has started on the Fraser Coast.
QMulching and C-Wise have combined to trial the mulch, which is expected to improve crop conditions and fertilisation.
It has been going for about six weeks and is expected to produce about 400,000 tonnes annually.
Fraser Coast Mayor Gerard O'Connell said the trial would benefit the region.
"It's one of the most innovative things we can do," he said.
"I'm even interested to see if there are some new crops that can be introduced here on the Fraser Coast.
"I see this as economic development."
