1 Family Size Anaerobic Digester in Mexico University of the West – Sustainable Investing Club Bio Impacto Farbod Safaei, Juan Valencia, Lam Le

2 Work in Process Technical Aspects Social & Environmental Aspects Economic Aspects Project Costs & Possible Returns Anaerobic Overview Total Project Cost Government Subsidy Cost to System Owner Sales of Carbon Credits Micro Financing Upfront Investment

3 Biogas vs. Other Fuels Fuel Specific Energy (MJ/Kg) Energy Density (MJ/L) Energy Per CO2 (MJ/Kg) Notes Animal Manure N/A Common respiratory diseases Increased infant mortality. Wood Poor labor efficiency Deforestation and desertification. Charcoal30N/A8 Low particulate matter High Carbon Monoxide Inefficient production process Ethanol Reduces food supply Very clean burning Natural Gas (Liquefied) Very efficient burning Fossil fuel Produces Propane as a by- product Biodiesel May be renewable Biogas55 23 (Liquefied) 20

4 Problems & Opportunities in Mexico Feedstock (Manure & Crop Waste) Waste Management (Black Water) Import Gas from the U.S Access to Electricity and Gas Electricity Price Natural Gas Price

5 Anaerobic Digestion Overview Bio Waste Anaerobic Digestion Biogas Heat Fertilizer CHP Bio Fuel Electricity

6 Fixed Dome Anaerobic Digestion Pros Low cost No moving parts, long life No rusting parts Underground construction Local employment Cons May become porous or crack Biogas pressure fluctuates Cooler than ideal temperature

7 Environmental Benefits Improvement of Air, Water Quality Reduction of Deforestation and Degradation Source: Biogas Support Programme (BSP) Nepal 1 AD =

8 Social Benefits 1,100 hours per year (3 hours per day) Reduction of Workload (Cooking + Collecting) Reduced disease outbreaks Reduced per capita spending on healthcare Improvement of Sanitation And Health (Human & Animal) Source: Biogas Support Programme (BSP) Nepal Creation of Employment and Economic Activities 1 AD = Energy Independent Households

9 Economic Benefits Source: Vietnam Biogas Programme $ per year Savings of Fuel Cost 67% Increase of Livestock Production 5-20% Increase Crop Yield (Using Fertilizer) 1 AD = $ 515

10 Benefits Summary Reduced Electricity & Fuel Cost Increased Production of Crop & Livestock Reduced GHG Improved Soil Conditioning Less Pollution, Less Chemical Fertilizer, Less Waste to Water System Better Waste Management Reduced Chemical Fertilizer in Food Production Time savings Reduced risk of waterborne and respiratory disease Income from Credits Sales Reduced Chemical Fertilizer Cost

12 Project Financing Government Subsidy Sales of Carbon Credits Cost to System Owner Micro Financing Upfront Investment Total Project Cost

13 Government Subsidy Banco de Desarrollo (Mexican Development Bank) BusinessInfrastructureHousing Rural Financiera Rural FIRA Up to 50% (Project Under $1 MXN)

14 Carbon Credits Sales CMD Pros: More attractive Higher values and more predictable Cons: Complicated & Expensive Procedures Small size project Voluntary vs. Pros: Less standardized Less effected by CDM commitment period Cons Less potential buyers

15 Micro-Financing Micro Financing Private Equity P2P Lending Philanthropic Organization

16 Work in Process 2.0 Government Subsidy Sales of Carbon Credits Micro Financing Detailed Working Plans Sustainability Metrics Financing Plan

17 Thank You Q&A
