Information Sheet 31: GHG reduction using biogas technologies
Without significant cost or effort the upgrading of municipal and waste water treatment facilities and the treatment of residual food waste to produce biogas can contribute an additional 3.0 PJ of energy and reduce greenhouse gas emissions of 515 kt CO2-e pa by 2050. If national zero organic waste to landfill policies are enacted and agriculture is required to treat farm wastes to avoid runoff of nutrients into waterways then significantly more greenhouse gas emission reductions can be achieved. The biogas can be used to generate electricity, produce heat, used as a vehicle fuel and a feedstock for manufacture of bio-based materials.
