1. Biomass to Energy at UW Oshkosh Michael Lizotte Director of Sustainability 2010 Biotechnology Vision Summit August 25 Madison Marriott West

2. UW Oshkosh Snapshot Founded in 1871 3rd largest university in Wisconsin (top 5% in USA) 13,200 students –9% increase over past 6 years –Growth Agenda - potential increase of 12% by 2025 (approaching 16,000) 1,500 Faculty and staff

3. Biomass (Food, Agriculture Waste, Yard Waste) Anaerobic Dry Fermentation Digester Biogas (Methane) Generator (CHP = Combined Heat and Power) Electricity, Heat and Compost www.biofermenergy.com/us Biomass to Energy

4. UW Oshkosh Renewable Energy Facility Methane Produced by Dry Fermentation of Organic Waste Burn biogas to generate electricity and heat Rooftop Photovoltaic Panels and small wind turbines Outreach, Education, and Research

5. GAS STORAGE GENERATOR GAS Sealed Chamber BioFerm System: 3 Basic Components

6. GAS STORAGE PERCO- LATE GENERATOR GAS Sealed Chamber “Dry” Process – water is recycled (no wastewater produced) “Percolate” – water, nutrients, microbes

7. GAS STORAGE PERCO- LATE GENERATOR GAS Sealed Chamber BIOMASS Add Biomass to Chamber…

8. GAS STORAGE PERCO- LATE GENERATOR GAS BIOMASS Oxygen is used up and methane is produced…

9. GAS STORAGE PERCO- LATE GENERATOR GAS BIOMASS HEAT ELECTRICITY HEAT Electricity and Heat are generated… Solid “digestate”  aerobic composter site (can be custom batched – e.g. organic)

10. MAIN CAMPUS URBAN SITING -- Facilities Management moved across the river (refurbished supermarket) -- Zoned for light industry -- Neighbors: -- sewage treatment plant -- yard waste dropoff site -- technical college -- senior center

11. UW Oshkosh Renewable Energy Facility UWO CSC Oshkosh Wastewater Treatment Plant Fox Valley Technical College Oshkosh Senior Center Oshkosh Yardwaste Collection Site WPS UWO Campus BIOGAS FEEDSTOCK ELECTRICITY HEAT Generators: 450 kW (330 + 120) Annual Electric: 3,000 MWh (ca. 10% of UWO) Annual Heat: 3,400 MWh (ca. 10% of UWO)

12. Hypothetical Feedstock Source Profile Tons Per Year Year ( Note: Facility lifetime is >20 yrs) Municipal Food Industrial Food Processor Waste Farm Waste Municipal Yard Waste UWO

13. The Bigger Picture for UW Oshkosh: 1.Renewable Energy Facilities serve as Learning Labs: -- Major: Biomass and solar -- Minor: Geothermal -- Demonstration: Wind 2.Research Laboratories for Service and Training: -- Biosolids and Water Testing (UWO strengths in Chemistry and Microbiology) 3.Renewable Energy Institute for Professional Development -- Short Courses, certificates, visiting scholars
