Digesters

In order to generate energy from manure, you need to have the proper environment for bacteria to grow and a way to capture and utilize the biogas being produced.

Keller Engineers has designed systems that utilize organic waste such as livestock manure, food waste, and beverage waste to produce biogas. The biogas is collected and used to power generators to provide electrical energy.

In addition to producing energy and generating money, our clients have received residual benefits including reduced manure odors, nutrients in manure converted to a better plant accessible form, manure pH increased to eight, weed seeds digested by the bacteria reduced herbicide when manure is applied to land, and digested manure solids are dried and reused for animal bedding.
