What We Do
We Provide Faster Alternatives to OEM Manufacturing

We specialise in the manufacture, repair and reverse engineering of components for the AD industry, providing dependable solutions when parts are worn, damaged or no longer available. Supported by our in-house CAD team, we can accurately design, adapt and improve components to suit real operating conditions and specific customer requirements.

We Are Known For Our Reliability
A key focus of our work is improving reliability. Where recurring issues arise, we don’t just replicate parts, we redesign and re-engineer them to improve lifespan and performance. We understand the pressures of keeping a plant running, which is why we prioritise efficient turnaround times and clear communication to help minimise downtime.

Servicing Anaerobic Digestion Plants Across the UK

Many anaerobic digestion plants rely on original equipment manufacturers located across Europe. When a critical part fails, waiting for replacement components can take weeks or even months.

We provide a faster alternative.

For example, a replacement digester screw from an OEM can take 12 to 14 weeks to manufacture and deliver. Our team can typically manufacture the same component in one to two weeks, helping plants return to normal operation far sooner.

Speed matters when your plant runs 24 hours a day. Our focus is simple. Deliver high quality parts and repairs as quickly as possible.

Frequently asked questions

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.

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.

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.
