"Things have been going well and the (ECS) Aerated Static Pile Composting System has worked great for nearly one year now. It has allowed for much more efficiency in our operations, produces a more consistent quality product, and very importantly has allowed us to manage the odor issues we had previously. Our markets are growing for finished compost and the future looks bright. We have showcased the facility to the Missouri Department of Natural Resources and US EPA Region VII officials and to elected officials from throughout the state last fall during the Missouri Municipal League Convention held in St. Charles County and all who have visited have been very impressed."Russell BatzelManager, Public Works Services GroupSt. Peters Missouri
