What You Should Know
As the nation’s first commercial-scale dry fermentation anaerobic biodigester, it is important to understand what the facility is and how it works. UW Oshkosh worked with BIOFerm Energy Systems, a subsidiary of Viessmann Corporation of Allendorf, Germany, where this technology is in full operation at several sites.
The majority of the input is provided by campus and local community sources with the remainder supplied from additional area partners.
- A dry biodigester can use waste from food, agriculture and yards.
- Inputs remain stationary and indoors throughout the process, while air filters remove any adverse smells.
- Anaerobic digestion uses input material that has moisture content less than 75 percent.
- No movement of organic matter, addition of liquid, pre-treatment of biomass or organic waste is required.
- No sorting of inputs is required prior to loading chambers, saving both time and money.
- The facility has low energy consumption, using 5 percent of the energy generated for plant operation.
- Waste water is eliminated, therefore removing risk of groundwater contamination.
