This dairy farm located directly on Lake Champlain will soon have its own Watershed Digester system.

Our new “Watershed Digester” concept interconnects a variety of known practices and technologies for a result greater than the sum of its parts. It is ideally suited for dairy regions with serious water quality problems caused in large part by phosphorus runoff from farms.

By quantitatively demonstrating a reduction in phosphorus, farms are now able to access grants and incentives that focus on water quality. In many regions this means the farm’s EQIP allocation from NRCS. Hundreds of thousands of dollars made available each farm bill.

For example, the environmental focus in Vermont is high phosphorus levels in Lake Champlain. Fortunately, when digesting is combined with the separation of liquids and solids, it becomes more manageable.  The bedding solids contain a higher level of phosphorus and the liquid fraction significantly less than raw manure. Along with less phosphorus, the liquid digestate has higher liquidity so it is more easily drag lined and injected in fields. The excess bedding solids can be sold as soil amendment to plant nurseries. It can also be sold, after being used(!), to compost companies and transported off the farm. This further reduces overall phosphorous levels.

Our unique, economical digester for mid-size farms (250-750 milking) is the centerpiece for a system mitigating phosphorus runoff.

In Vermont the Natural Resources Conservation Service (NRCS) is all about improving water quality in Lake Champlain

Our Watershed Digester concept starts with slurry feedstocks then branches out to create farm revenue from electricity, heat, bedding and water quality improvement. Call us for more details.
