The project will develop a waste processing facility which will use moving grate technology to process approximately 400,000 tonnes of municipal solid waste, commercial and industrial waste and/or pre-sorted construction and demolition waste per annum to produce approximately 36MW of baseload power for export to the grid.
How the project works
The Kwinana facility will use Keppel Seghers moving grate technology, which thermally treats the waste and converts the recovered energy into steam to produce electricity. Metallic materials will be recovered and recycled, while other by-products will be reused as construction materials.
Area of innovation
The Kwinana Waste to Energy facility is an important and significant renewable energy project for Western Australia and Australia. It will be the first thermal utility scale Waste to Energy facility constructed in the nation, diverting approximately 25 per cent of Perth’s post-recycling rubbish from landfill sites.
When complete, the facility will divert 400,000 tonnes of household, commercial, and industrial waste from landfill each year, which represents a quarter of Perth’s post-recycling rubbish. The facility will use the residual waste to generate energy, recover and recycle metals, and re-use the remaining ash residue as construction materials. Once operational, the facility will result in an overall reduction of carbon dioxide emissions of more than 400,000 tonnes per year, which is equivalent to taking 85,000 cars off the road. The facility will also export 36 MW of electricity to the local grid per year, sufficient to power more than 50,000 households.
