Other biomass
Plants for producing biogas from certain industrial wastes have been found to be economically viable, with payback periods as low as 2-4 years for larger plants when credits for waste treatment or disposal are taken into account. A few such technologies are currently being used commercially in Victoria, although there is a significant untapped potential energy contribution from this source.The Carrum and Ballarat sewage plants use the biogas they produce for heat and electricity production and a factory at Ballarat produces biogas from potato wastes. The annual primary energy contribution from these sources in 1982-83 was estimated to be 0.3 PJ. A plant has been built as a result of a joint Victorian Solar Energy Council and industry project to convert starch processing wastes to biogas to contribute a further 0.1 PJ per annum.
At a disused municipal tip in the City of Northcote, Victoria a demonstration project has begun operation using biogas from extraction wells as fuel for an engine-generator supplying electricity to the local distribution system for consumer use.
