Engineering & Plant Operation

Marches Biogas is an anaerobic digestion (AD) engineering company that was formed in 2009. The company has extensive experience of plant design, equipment manufacture, installation and ‘operation and maintenance’ from years of working within the industry and having built and maintained over 30 anaerobic digestion plants across the UK, ranging from 50 kWe to 2MWe utilising feedstocks including energy crops, farm slurries, food and industrial wastes.


Water Authorities

Marches Biogas works closely with Water companies and their partners helping them to maintain and operate their sludge digesters safely and efficiently.

This work includes trouble shooting both biological and mechanical process issues, maintenance of boilers, surplus gas burners, pressure relief equipment, mixing and heating systems, DSEAR & site safety surveys and lithium trace tests.


The Future

While Marches Biogas has always offered independent AD engineering services a significant part of the business has been the design and installation of turnkey AD plants.

There has recently been a decline in the demand for these types of projects so over the past months we have been working to refocus the business through the delivery of our core services by setting up separate support and consultancy divisions. This is now being formalised through the establishment of Evolution Biogas and Principle Biogas.

Evolution Biogas is the support division of Marches Biogas Ltd. Evolution Biogas supports operational anaerobic digestion plants throughout the UK and continually works to improve the performance of facilities through the provision of the following independent services:

  • • Biological Support
  • • Feedstock Planning and Advice
  • • Reactive Mechanical, Electrical and Instrumentation Support
  • • Proactive Mechanical, Electrical and Instrumentation Support

    As a family farming partnership it was important we chose a company that would provide an AD plant that was not only well built, easy to maintain, cost-effective and efficient but also flexible to our requirements. Marches Biogas has more than exceeded all these requirements, always going that extra mile with an attention to detail second to none.
