Through implementing a dry fermentation anaerobic biodigester system, UW Oshkosh is creating a better environment for the campus and local communities. The plant will lengthen the lifespan of landfills, increase capacity at compost sites and decrease energy consumption and cost of moving waste.
Through a dry fermentation process, only 60 percent of waste that goes into the biodigester is left over after the 28-day cycle. This remaining organic material is equivalent of advanced stage compost and be further processed and used around the UW Oshkosh campus and city of Oshkosh.
Turning waste into a resource
Food scraps, yard waste, food processing waste and agriculture waste are all considered organic waste added to landfills and compost piles every day. Instead of dumping and ignoring this waste, the biodigester is turning organic waste into a resource producing up to 5 percent of campus’s electricity and heating needs.
Reducing greenhouse gas emissions
By monitoring decomposition of organic waste in a controlled environment, the UW Oshkosh biodigester system is able to capture generated methane that would otherwise be released into the earth’s atmosphere in an open, uncontrolled environment.
