Recent Gearbox Repair
We have recently finished work on a Huning planetary gearbox, including bearing replacement and installation of a new spline shaft.
Following strip-down and inspection, worn components were identified and replaced to restore correct tolerances and performance.
We completed the bearing change and housing inspection, manufacture and fitment of new spline shaft, before alignment and reassembly to specification.
All work was carried out to ensure reliable operation in demanding AD environments and minimise unplanned downtime.
Built Around Speed and Reliability
Quick Turnarounds
We focus on rapid turnaround for both manufactured components and repairs on anaerobic digestion sites. In many cases we can produce replacement parts such as digester screws in one to two weeks, compared with typical OEM lead times of twelve to fourteen weeks.
Extensive Knowledge Across Our Team
Our team has developed extensive knowledge of AD plant equipment and the challenges operators regularly face. This allows us to identify issues quickly, understand the demands placed on each component, and manufacture or repair parts with confidence.
Solutions Focused
Every plant and every piece of equipment presents slightly different challenges. Components often fail due to wear, operational conditions, or unique design characteristics. Our approach is focused on practical problem solving. We assess the component, understand the cause of the issue, and manufacture or repair the part to ensure it performs reliably once returned to service.

Frequently asked questions
What types of machinery do you manufacture for anaerobic digestion plants?
We manufacture a range of specialist components used within anaerobic digestion facilities, including digester screws, augers, conveyors, and other fabricated machinery parts. Our team can produce replacement components for existing equipment or manufacture new parts based on your plant’s requirements.
Can you repair existing anaerobic digestion machinery?
Yes. We regularly repair and refurbish worn or damaged components used in AD plants. In many cases repairing an existing part is faster and more cost effective than waiting for a new component from the original manufacturer.
Do you only work with UK anaerobic digestion plants?
While many of our clients are based in the UK, we can manufacture and repair components for AD plants across the wider industry. Our goal is to support operators who need fast and reliable engineering support.
