Anaerobic digestion (AD) is a major investment. Farms typically spending anything between £1.5m and £3m for a farm-scale system.  The return (for electricity generation) could be between £300k/yr (250kw) and £750k/yr (500kw).  Optimising the performance of these AD plants is key to a successful business.

We can advise on all stages of the process, from feasibility, planning and permitting, to compliance.

Achieving compliance

Whether you have a permitted or exempted anaerobic digestion process, you will also need to meet the conditions of the permit and planning.

We are ideally placed to help you with any anaerobic digestion-related compliance issues you may have, including:

  • Complaints about odour in the countryside
  • Meeting the obligations of the Silage Slurry and Agricultural fuel oils (SSAFO) regulations and NVZ rules for digestate recycling. These are in place to minimise the risk of pollution from structures and field activity.
  • Ensuring your system meets the construction guidance on silos and tanks and lagoons produced by the Construction Industry Research and Information Association (CIRIA).
  • Ensuring you have enough storage capacity over the closed spreading period.

Our expertise

Our engineers have over 40 years of AD experience. We have audited over 1000 farms with silos and lagoons for pollution pathway and have written the report that was sponsored by the regulator.
