Technology

Our proposed Anaerobic Digestion (AD) plant will treat food waste from the South London area.

AD is a process whereby plant and animal material (biomass) is converted into useful products by micro-organisms in the absence of air.

Biomass is put inside sealed tanks and naturally occurring micro-organisms digest it, releasing methane that can be used to provide heat and power.

Compost materials are then matured and can be used as a fertiliser as it is rich in nutrients. The digestate from the AD process can also replace some synthetic fertilisers.

This means AD can help reduce fossil fuel use and reduce greenhouse gas emissions. 

AD is not a new technology and there are a growing number of AD plants in the UK processing our waste and producing energy.
