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 teamed with Keller Engineers on several design-build projects for PennDOT. When selecting a designer, the more critical factors are trust and competence, more so than a low price. If your designer makes a mistake in quantities it can cost you a lot of money. We have stayed with Keller Engineers because we trust them to provide competent service at a competitive price. S.
