Biogen Greenfinch

Location: Milton Ernest, Bedfordshire
Years: 2005-present
Leader: John Ibbett


Biogen promotes, develops and utilizes new technologies to respond to today’s environmental challenges. They deliver eco-technology solutions that meet those challenges while supporting the sustainability of the environment, farming and rural communities. Biogen was established to develop a new farm based on Anaerobic Digestion (AD). AD is a natural biological process using naturally occurring micro-organisms to break down organic matter into fertilizer while producing biogas. The anaerobic bacteria utilized in the process are commonly found in soils and deep waters. AD is split into three main stages: hydrolysis, acidogenesis, and methanogenesis. After methanogenesis, a combined heat and power engine is used to conver the biogas into heat and electricity.

Biogen uses its own pig slurry to feed the AD process and also provide a local recycling solution for other food chain waste in the UK.
