Our team have a track record of delivering successful anaerobic digestion (AD) projects, going all the way back to developing one of the first AD plants in the UK over 15 years ago. AD continues to be at the forefront of our market leading work.

We have built up a team of specialist engineers from a range of disciplines who have a significant track record in the delivery of AD projects, and we can offer a full cycle service for your project from feasibility (including feedstock assessment and large scale pilot trials) to procurement, planning, permitting and construction.

For post construction we can help assist with all plant operations, technical support, and plant upgrades to enable our clients to secure long term, stable running of their AD plant.

We have significant project experience across a wide variety of sectors including distilling and brewing, chemicals, pharmaceuticals, food and drink and agriculture.

We strive to be at the forefront of AD development and are continually looking for ways to integrate the newest AD technology with concomitant biotechnologies, recently investigating the application of algae as a clean-up mechanism for biogas. We regularly collaborate with research groups, private industry and public and private funding groups to finance, design and build innovative AD projects.

Services we provide:

  • AD and Biofuels project identification and feasibility studies;
  • AD feedstock assessment;
  • Development of investment grade business cases for AD and Biofuels projects;
  • Pilot plant trial operation and management;
  • Contract drafting (IChemE suite and NEC3);

  • Project management of AD detailed design, construction (inc. procurement) and commissioning;

Project Examples


  • As Comhairle nan Eilean Siar moved away from landfill to finding sustainable solutions for domestic and commercial waste Uisdean and his team identified AD as a viable option and after detailed consideration of all options backed by detailed research and expert advice he was tasked to deliver the (then) highest value capital project ever envisaged by the Council. This involved detailed financial negotiations at the highest levels as well as a detailed 7-year delivery plan, involving major stepped structural changes in the service delivery to ensure that the structure were in place for the delivery of the capital project. Uisdean and I worked very closely to find practical, financial and political solutions to all the problems, and when the budget was halved by Government, he was still able to design and deliver the project on time and to the new budget. Since then, Uisdean has gone from strength to strength in the private sector providing solutions to firms of all sizes with a variety of business needs. I cannot recommend Uisdean highly enough.
