Proven Composting Solutions

Our designs are based on deep scientific understanding of the composting process, our rigorous engineering approach, and our nearly 20-year quest for continuous improvement.

We are proud of the depth and breadth of compost facilities that we have engineered and built. We believe that there is no single system, mixer or cover that is so perfect it works in every application. Rather, that each facility requires a customized design and an appropriate technological solution to achieve its process, market and financial goals.
