For the Capital to meet its waste minimisation and zero carbon targets the council has to change the way it deals with sewage sludge.
Currently, WCC disposes of its wastewater (sludge) by mixing it with rubbish at the landfill, which requires a lot of general waste to offset it, at a ratio of no less than 4:1, but that's causing knock on effects for waste minimisation targets and it's a liability for the council under the ETS.
So what is the state of the art, but costly solution being proposed?
