7. Engine and generator running on Syngas BEST Demonstration Plant

8. Data Collection Engine Control Panel 40 Thermocouples Syngas Analysers Data Loggers

9. Biomass Feedstock A complete range of biomass feedstocks have been evaluated Over 150 hours C4H4 runtime in total Feedlot Manure Poultry Litter Paper Sludge Wood Waste Rice Hulls Corn Trash Cotton Trash Woody weeds Green Waste

10. C4H4 Gas Analysis Gas analysis with GC (Gas Chromatograph) after gas clean-up Greenwaste feed Gas CV approximately 7 MJ/kg [range 6-12 MJ/nm 3 ] Gasifier gas approximately 3-4 MJ/kg depending on feed Clean gas suitable for use in engines or boilers Minimal ‘’tar’’ < 250 mg/m 3 from hot gas filter prior to scrubbing Renewable source of energy

11. Char Analysis Char yield between 27 and 50% of feed (dry) Activation to give high surface areas – up to 800 m2/g Sampling possible directly from kiln or char activator 50% Carbon from biomass remains in char – sequestration potential Greenwaste Char Analysis Chicken Litter Char

12. Char as a Soil Amendment Collaborative Char research with NSW Department of Agriculture and The University of New South Wales. Soil structure (tensile strength) Cation exchange capacity Water holding capacity Soil permeability Nutrient retention Enhance soil carbon Liming value Available nutrient content (NPK) Reduced soil greenhouse gas release

13. Agricultural Trials
