Project Development

• SCI sponsored missions in early 2004
• Waste Management and Energy Amongst Key Roadmap
  Issues
• Waste Tires a Major Concern Along Border
• City Needed to Rehabilitate Old Dump and Site
  Modern Landfill
• Electricity a Significant Municipal Expenditure
  US4M/year

5
Project Context

• Population of 600,000
• Rapid growth in population has stressed municipal
  infrastructure
• Dump Impacts on Environment
• Fires, air quality, LFG emissions
• Groundwater quality impacts
• Large scavenging community
• Scrap Tire Dumps are Breeding Ground for
  Vectors/Disease
• Gulf of Mexico Proximity Offers Good Wind Energy
  Potential

6
Renewable Energy as Sustainable Development

• Three Pillars Social, Environmental, Economic
• Do not leave our problems for future generations
  to manage
• Renewable Energy Sources
• Do not leave legacy environmental impacts
• Do not deplete existing resources
• Reduce greenhouse gases
• No environmental footprint
• Are economically viable
• Amenable to smaller distributed energy rural
  poverty reduction agenda

Matamoros Green Energy Facility

• Comprised of Three Energy Components World First
  Innovative Green Energy Facility
• Pyrolysis Transformation of Tires, Wood, and
  Other Wastes Into Electricity
• Technology Creates Syngas Fuel
• Recyclable Non-Hazardous Residuals Generated
• Landfill Diversion, Solution for Waste Tires
  Along Border
• LFG Capture From Dump
• Control of LFG Fires and Odours
• Reduced GHG Emissions and Dependence on Fossil
  Fuels
• Develop Wind Farm Along Drainage Canal
• Flat Terrain, Good Wind gt 8 m/s

8
Matamoros Green Energy Facility

• Overall Energy Potential 20 MW
• Greenhouse Gas Reductions
• Single Integrated Electrical Substation and Power
  Line Transmission Connection
• City Could Save Over US4M/Year in Electrical
  Bills
• Facility to be Developed at Old Dump Site
• Part of Overall Site Rehabilitation Plan
• Reasonable Post-Closure Land Use
• Opportunity for Local Job Creation at Plant
• New Modern Landfill Site Constructed
• Local Job Creation at New Landfill

Wind Energy Facility
18 Wind Turbines Height 70 Metres Diameter 54
Metres
Load Factor 30 Annual Energy Production
39,000 MW-hours Located along Existing ROW of
Drainage Canals
12
LFG Generation Potential

• Site Contains 1.2 Million Tonnes of MSW
• Estimated LFG Generation 290 scfm of Methane
• GHG Reduction 60,000 tonne CO2e/Year
• No Existing LFG Management System
• Landfill Fires and Air Quality a Major Concern
  Dump Closed
• Methane a Significant Greenhouse Gas

13
Scrap Tires as Solid Fuel

• Tires Offer 32,000 kJ/kg as Energy
• Mexico Generates 15 million Tires/Year
• 80 go to Dumps
• 15 in Cement Kilns
• 5 Recycled
• Approx. 25 million Tires Already in Dumps
• Illegal Importation of Tires from US a Concern

14
Additional Solid Waste Fuel Sources

• Wood Waste
• Generated from Manufacturing Industry Along
  Border
• Other High BTU, Non-Organic Industrial Waste
• Plastic, Rubber, Foam, Paper, Textiles, etc.

15
Pyrolysis Plant Components

• Pre-Processing Shredder for Size Reduction
• Achieve lt 50 mm Size, Remove Steel
• Retort Chamber to Gasify Solid Organic Fuel
• Creates Syngas at 750 to 850 oC in a Vacuum
• Residual Carbon Char Removed/Recycled
• Thermal Oxidizer for Combustion of Syngas and
  Destruction of HAPs
• Operates at 600 to 750 oC
• Heat Transfer from Exhaust Gases to Steam
  Boiler/Turbine Power Generation
• Combined with Gas Turbine Pre-Heater for Air
  Supply to Thermal Oxidizer
• Air Emissions Control Technology
• Wet Scrubber Using NaOH to Remove SOx and
  Particulates

16
Feasibility Study
