Biogas Used for Electric Power

In an earlier blog, I talked about anaerobic digestion––the degradation of organic material by anaerobic bacteria. The anaerobic digestion process is not just used in the treatment of human wastewater. It can be used with any type of manure or organic waste product. During this biological degradation, a combination of methane gas and carbon dioxide is produced. This biogas may be used to raise the temperature in the digester itself, making it more efficient to heat buildings or to produce electric energy to be sold back to the grid.

The following article discusses a startup in Wisconsin that is using a co-feed stock system utilizing whey from cheese making, waste soy protein and other waste food products to produce electric energy for the local grid.

I don’t think this is way off the mark since I know of at least one start-up facility in Kentucky with the same idea.
