In the US the University of Wisconsin-Oshkosh (UWO) is to install a dry fermentation anaerobic biodigester for the production of biogas from yard and food waste.
Designed by BIOFerm Energy Systems, a provider of clean renewable energy solutions, the $3.5 million (€2.6 million) plant will generate 3071MW a year of electricity and 4183MW a year of heat for the campus. Any excess power will be sold to the grid.
The system will divert an estimated 8,000 tonnes of organic waste a year away from landfill, including food leftovers from cafeterias located around the campus. It also has the ability to handle grass, animal bedding and methane gas.
2G-Cenergy, a Florida, US-headquartered manufacturer of CHP systems, will supply the 370kWh biogas CHP cogeneration system, which is to be located on Dempsey Trail, adjacent to the Witzel Avenue Campus Service Center at the university. The UWO owns and operates the plant.
The CHP plant uses the 2G optimus 370BG, an optimised MAN cogeneration gas engine fully integrated into the 2G biogas cogeneration technology package, especially developed for biogas operations. The plant is fully containerised and will be supplied as an all-in-one and connection-ready module.
The 2G system – the first genuine biogas cogeneration plant of this kind to be operated by UWO – has enough capacity to power a large portion of the university campus. An extension is planned for 2012.
