London produces approximately 1.3 million tonnes of organic waste per year. The application of anaerobic digestion is one of the most promising ways to reduce the impact this waste has upon the environment. 

The project aims to install and monitor a novel and affordable anaerobic digester (manufactured by BioBolsa in Mexico) at an urban farm pilot site within the Greater London area.

Low cost bio digesters can be used to treat organic waste within urban areas, with the benefit of reducing CO2 emissions from refuse collection vehicles. The digester also adds value to the waste treatment process by simultaneously producing biogas for combustion and liquid fertiliser for use by the farm and local gardeners.
