4. Process Overview Ultra-Clean Gasifier Small Scale FT Process WET-EIG’s Technology 4

5. Human Sludge Processing Dewater Originally sewage is ~80% water, so de-water to ~40% Waste heat will reduce this to ~30% before entering gassifier Gasify & Clean Scrub away sulphur (H2S), nitrogen (N2) and oxygen (O2) Produce clean synthesis gas (CO and H2) Burn to generate electricity or condense into diesel Generates ~1.2 MWhr/tonne of dewatered sludge, or Produces ~230 litres/tonne of dewatered sludge 5

6. Technology Background Since 1990 the Company has installed over 1000 low NOx burners It has set the California’s emissions standards 4 times, currently < 9ppm NOx, < 50ppm CO First experience in gasification in Daoling, China in 1993 Makes 24,000 gals/day of fuel from tyres Pyrolizetyers at 400-450°C to make black oil suitable as coal substitute for power production, but not good for autos, more like light bunker fuel with ~0.4% sulfur Built a similar 12,000 g/d tyre plan in Nankang, Taiwan in 2000 Produces a cleaner fueld Italy glass recycling plant Since 4yrs, 100 kg/hr, remove plastic & metals from auto glass Heat used for power generation to run the plant, though still in pilot Larger plant being designed at 500 kg/hr 220 kg/hr plant in Oregon generates 265kW net power Human sludge plant in Los Angeles (Carson), demo plant @ 50 kg/hr Has led to orders for 4 plants at 1-10 ton/hour for Brazil, China, Malaysia, India 6

7. Pyrolysis Step Processes carbonaceous material, such as coal, wood chips or sewage sludge into carbon monoxide and hydrogen (CO + H2) Partial vacuum – reduces oxygen content in the chamber Reducing oxygen content reduces CO2 + SOX formation Patented burner system leads to lowest NOX emissions in the world Rotating feed column circulates coal in reactor over a period of time (30mins -55mins) Inert ash is collected at the base of the reactor Ideal feedstock Water content ~25% Increases hydrogen production Low ash / high calorific condition Low Sulphur Reduce cost of clean up stage 7 C + H2O -> H2 + CO

8. Low Temp Gasifier Technology Gasifies organic matter, coal or pet-coke at 750-1000 F to produce syngas (H2, CO and CO2) Syngas used to create synthetic diesel and other petroleum products Remainder used to generate electricity for plant Operates too cool to for CO or NOx 400-650°C (750-1200°F) vs 980-1650°C (1800-3000°F) 12 proven units in the field operating various feedstock Coal, pet-coke, municipal solid waste (MSW), tires, plastics Automatic augur system removes slag Less maintenance, longer catalyst life 8

9. Steam Reforming step The F-T process requires a ~2:1 hydrogen to carbon monoxide ratio Most coal types do not produce enough hydrogen Additional hydrogen is created in the reforming step Pyrolysis step also produces a large amount of methane, perfect for reforming with steam CH4 + H2O  3H2 + CO CH4 + 2H2O  4H2 + CO2 Depending on operating conditions either reaction 1 or 2 will be favoured. Reaction 2 generates more hydrogen but as a consequence generates more CO2 % gas composition after pyrolysis 9

10. Fischer-Tropsch Process As previously stated the H2 and CO must be fed into the reactor as 2:1 ratio to maximise conversion efficiency All sulphur and other contaminants must be removed to prevent poisoning the catalyst The process uses a floating bed reactor with a high boiling point fluid to transport the F-T catalyst Encourages mixing and reduce chance of carbon deposits on catalyst There are 2 types of catalyst WET-EIG Asia promotes Iron Oxide Cheaper but more susceptible to pressure changes. Produces lighter hydrocarbon chains Cobalt Produces a constant stream of product not depending on pressure. Also catalyst tends to produce heavier compounds, ideal for refinery specification Reaction formula: 10 (2n+1) H2 + nCO -> CnH2n+2 + nH2O

11. 50kg/hr Test Plant 11 In addition to sewage sludge, the company has gassified over 75 types of coal, a dozen different plastics, rubber, rail road ties, municipal solid waste, medical waste and biomass (rice straw, grass, wood chips, soy bean shells, switch grass), chicken manure, cow dung, etc. Test burn of synthesis gas Burner / Gasifier Fischer Tropsch Unit Synthetic Diesel

12. Sewage Sludge-to-Diesel Pilot Plant 12 Human sludge plant in Los Angeles (Carson), demo plant @ 100 kg/hour Has run 24 hours/day almost continuously since January, 2009 Avoids $70/ton transport charge to San Diego Reduces volume by 92%, lose 1.8%, remaining residue (carbon/phosphorus) makes good fertilizer Give back surplus water Currently planning for 60 ton/hour plant for 3.5 million population of Long Beach and surrounding area

14. 2 venturi scrubbers

15. Remove particulates

16. Cool syngas

17. 1 gas compression unit

18. 1 desulphurization unit

19. 3 towers if sulphur content is over 1%

20. 1 reforming step – hydrogen production

21. Steam injection

22. 2 PSA (Pressure swing adsorption) units

23. Captures and separates H2 and CO

24. Enables plant operator to control gas ratio in F-T process

25. 1 F-T reactor for liquid fuel production

27. Sewage Plant Capacity Plant size depends upon size of legacy deposit and on-going population needs 15 Note: on a wet basis the figures above will be 5x larger

28. Versatile FT system No water for sewage sludge Other feed stocks require little water (1.5 litres water / litre diesel) Competing systems use up to 24 L water / L diesel High yield (~65% efficiency, best in class) Actual conversion depends energy content of the feedstock Testing with many dozen types of coal, waste, biomass and sewage sludge Sulphur content easily removed Coal illustrates that yield depends upon heat value of feedstock Sewage sludge varies by diet, but is roughly 10,000 BTU/lb or 5,600 kcal/kg 16

29. Plant can be configured to produce just electricity, just fuel or a combination Factors to consider Generating electricity is less expensive, but power is very difficult to store Better overall conversion efficiency, though it also depends upon turbine efficiency A range of fuels can be produced In addition to diesel, the plant can produce gasoline, jet fuel and, if there is demand for it, then certain waxes Output: Power vs Fuel 17

30. Sewage to Power Economics 18 Note: Capex depends turbine cost (ranges $0.7-1.3m/MW); returns also depend upon sales price of power ($/kWhr).

31. Sewage to Fuel Economics 19 Note: Returns depend upon sales price of fuel ($/L).
