5 Plasco Conversion vs. Torch in a Pot

6 Maximum Value 99.8% of waste is converted to clean fuel and valuable products

Waste heat is recovered for additional power.

8 Operational Experience Over 1 Year of Operations have focused on : Identify methods for handling variability in waste Identifying bottlenecks in the process Identifying inefficiencies in the process Engine Efficiency started feeding at 11:24 steady-state at 13:05 begin shutdown at 20: Syngas Composition % % Average Fuel Input = 1322 kw 80% % Feedstock HHV (MJ/kg) Syngas LHV (MJ/m3) Fuel Input (kw) Average Engine Efficiency = 38% 60% 50% 40% 30% % % :30 11:00 11:30 12:00 12:30 13:00 13:30 14:00 14:30 15:00 15:30 16:00 16:30 17:00 17:30 18:00 18:30 19:00 19:30 20:00 20:30 21:00 Time 11:00 12:00 13:00 14:00 15:00 16:00 Time 17:00 18:00 19:00 20:00 0 0% 10/25/ :31 10/25/ :38 10/25/ :45 10/25/ :52 10/25/ :00 10/25/ :07 10/25/ :14 10/25/ :21 Time Material LHV LHV of Syngas CO in Syngas (mol%) CO2 in Syngas (mol%) H2 in Syngas (mol%) O2 in Syngas (mol%)

Dioxins and furans are not directly comparable against jurisdictions but are provided for information purposes

11 Environmental Benefits Net Reduction of Greenhouse Gas Emissions

12 Displacing Emissions Sources: 1. Landfill with Power Generation: NPRI data for Vancouver Landfill, Power Generation: BC Hydro data for Burrard Thermal 3. Waste Trucking: Fleet Average Emission Factors for Garbage/Recycling Truck Fleet, Emission Reduction Options for Heavy Duty Diesel Fleet Vehicles in the Lower Fraser Valley, 2005

13 Plasco understands community interests Plasco is completely transparent Public website with: Emissions Performance Trends Regulatory Submittals Engineering Reports Project Background Information

14 Zero Risk Business Model PlascoEnergy builds, owns and operates its patented Conversion System No capital required from customers No operation risk In operation 12 months after permitting Environmental performance is guaranteed Long-term budgetary certainty competitive tipping fees are fixed for 20 years Revenue sharing above an agreed threshold
