What our clients say

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.
