1 The Flour Pot Bakery Waste Audit & Biogas Potential Danielle Keeter Bioenergy Summer School Internship 2009 The Flour Pot Bakery’s stand at the Haile Village Farmer’s Market

2 The Inspiration for this Project Ryan Graunke’s paper “Food and Fuel: Biogas Potential at Broward Dining Hall”Ryan Graunke’s paper “Food and Fuel: Biogas Potential at Broward Dining Hall” Won the Student Research on Campus Sustainability Award from the Association of the Advancement of Sustainability in Higher Education (AASHE).Won the Student Research on Campus Sustainability Award from the Association of the Advancement of Sustainability in Higher Education (AASHE). e2008.pdfhttp://www.aashe.org/documents/resources/Graunk e2008.pdfhttp://www.aashe.org/documents/resources/Graunk e2008.pdfhttp://www.aashe.org/documents/resources/Graunk e2008.pdf _1d195ecbab.jpg?v=0

3 Experiment Goals Conduct waste audit for The Flour Pot BakeryConduct waste audit for The Flour Pot Bakery Quantify average methane output from food wasteQuantify average methane output from food waste Use food waste as feedstock for anaerobic digesterUse food waste as feedstock for anaerobic digester

4 Methods Waste stream separated into: Waste stream separated into: Compostable paperCompostable paper Food wasteFood waste Recyclable metal/plasticRecyclable metal/plastic Plastics 1-7 and most metals 5Plastics 1-7 and most metals 5 Non-recyclableNon-recyclable Grind food waste to start homogenizing the sample Grind food waste to start homogenizing the sample Blend sample in food processor to complete homogenization Blend sample in food processor to complete homogenization Food waste then baked to analyze volatile solid contentFood waste then baked to analyze volatile solid content

5 The Process of Anaerobic Digestion Source 4

6 Anaerobic Digester Technology Anaerobic digester design: continuous stir tank reactor. Energy Park’s anaerobic digester:Energy Park’s anaerobic digester: 1 lb daily1 lb daily 100 liters daily at peak100 liters daily at peak

7 The Benefits of Biogas Provides power from waste Provides power from waste Decreases amount of material going to landfills Decreases amount of material going to landfills Nutrient rich output Nutrient rich output Use as fertilizerUse as fertilizer May be scaled according to project size May be scaled according to project size Provides local source of power Provides local source of power 8/images/best2.png
