Angela Bywater - Senior AD consultant

Angela has a background in IT and project management, having worked for a number of well-known UK companies, including House of Fraser and Sun Life of Canada. Since 2001, she has since been involved in a number of AD reports and projects; notably for the Royal Agricultural Society of England (RASE), which attracted significant worldwide interest; for Glasu (Welsh Government) on Farm AD & chicken manure; for the International Energy Agency Task 37 on small-scale AD; and RE-fuelling the Countryside for the RASE. A mine of useful information, Angie is currently working on setting up the UK’s AD Network and coordinates ADnet, a BBSRC funded initiative aimed at furthering innovation and promoting cutting-edge AD research.

James Murcott – Senior AD engineer

James is the founder and director of Methanogen UK Ltd, a British company, built on 40 years’ experience of designing, manufacturing and building anaerobic digesters for farms, sewage treatment, food waste and abattoirs. He also founded Farmgas, the UK’s largest AD company in 1974. His UK farm digesters alone have a combined operating time of more than 400 years and his company WRI created a market for their award-winning AD compost.  His latest designs include a range of micro-scale digesters and full-scale automatic de-gritting digesters, the latter a major AD innovation, allowing gritty feedstocks such as unwashed sugar beet and slurry from cows bedded on sand to be fed directly to the digester. A well respected in the UK’s AD sector, James brings a wealth of expertise to LEAP’ team.
