Proven Composting Solutions

Our designs are based on deep scientific understanding of the composting process, our rigorous engineering approach, and our 25+ year quest for continuous improvement.

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