Anaerobic Digestion is rapidly becoming a popular technology for breaking down organic matter into biogas. This biogas can then be utilised within generators to produce electricity.

Traditional anaerobic digestion plants are constructed at ground level and normally feature a number of tanks, storage vessels and other associated plant. This can be a blight on the landscape in particular sensitive locations.

GPJ Consulting Engineers have designed proposals for a number of discrete mixed plug flow digesters which are constructed below ground with minimal effect on the surrounding landscape. A feature of this particular design is the lack of moving parts within the digester, which simplifies operation, reduces maintenance and lowers installation costs.
