Project Details

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 and food and beverage waste to produce biogas. The biogas is collected and used to power generators that provide electricity.

In addition to producing energy and generating money, our clients have received residual benefits such as:

reduced manure odors
nutrients in manure converted to a better plant accessible form
manure pH increased to eight
weed seeds digested by the bacteria reduce herbicide use when manure is applied to land
digested manure solids are dried and re-used for animal bedding

We have worked with Keller Engineers for structural and civil engineering support on six projects over the past five years and have been very pleased with the results. Our projects tend to be complicated phased renovation/ addition projects calling for creativity in planning and construction. I have been particularity pleased with their responsiveness to issues that arise during construction which is of particular importance to us and our clients. Vern L.
