Information Sheet 47: The role of biogas in transition to low carbon economy
Processing residual waste can lead to a significant reduction in GHGs
Bioenergy Association has updated previous analysis and the new work shows that anaerobic digestion has the potential to eliminate 1,811 kt CO2-e pa of greenhouse gas emissions by 2050. This all can be achieved using well-established technology and existing waste materials with many other associated environmental and socio-economic benefits. The biogas can be used to generate electricity, produce heat, used as a vehicle fuel and a feedstock for manufacture of bio-based materials, further offsetting greenhouse gas emissions by substituting carbon-intensive fuels and resources. This is 4.6PJ of energy.
To achieve this greenhouse gas reduction requires rethinking how we treat waste has to be based on three principles;
- A national policy of zero organic waste to landfill by 2040.
- Minimise, recycle and reuse as much waste as economically possible.
- Aim to extract maximum value from waste by processing residual waste into compost, fertiliser and energy.
