1. Fossil or Mineral Fuels come from fossilized remains of dead animals and plants. Called non- renewable resources: (from millions of years exposed to heat and pressure from within earths crust; depletes faster than new ones being formed; burning produces about 21.3 B tons of carbon dioxide per year) 2. Biomass a variety of carbon-containing substances derived from living matter like fuel wood, bamboo, twigs and leaves, agricultural residues such as husks, stalks, vegetable oils & animal wastes. Used as fuel to obtain energy; burned to generate heat and provide illumination. 3. Ways Thermal Energy from Biomass are used: a. by boilers burned to boil water and produce steam b. by gasification converted into a gas that is burned for various applications 4. Biomass Gasification converts solid biomass to combustible gases with high conversion efficiency (85%) producing cleaner, steady and high temperature flame. 5. Bio-fuels come from hydrocarbon plants. Feedstock is planted first. Propagation scale is extensive to be viable. 6. Bio-fuels program for energy sufficiency and fuel diversification while meeting environmental challenges through utilization of bio-fuels (sunflower, hanga, petroleum nut, coco bio- diesel). Most feasible is bamboo which is the fastest growing timber plant on earth with many applications as a wood substitute. 7. Sustainable characteristics of bamboo: a. grows rapidly than trees like 400 mm or 15 per day b. matures in 4 to 5 years c. multiple harvests every 2nd year upwards d. lives up to 100 years e. produces biomass of up to 40 tons/hectare per year in a well managed bamboo stand or plantation 8. Advantages and uses of bamboo a. substitute for lumber b. effective for erosion control, watershed protection, soil remediation, carbon sequestration, environmental greening and for food 9. Sustainable village-level bio-fuel program using bamboo as feedstock in a 2000 hectare project (please refer to presentation slide) 10. Bio-oil is an organic liquid fuel from fast pyrolysis Fast pyrolysis is a rapid thermal decomposition of organic materials in the absence of oxygen 11. Bamboo as feedstock of bio-oil and bio-gas for power production. Good heating value. 12. Bio-coal is torrefied biomass; aka e-coal, green coal. No smoke/odor, clean, hydrophobic MCis 1%, easy to mill, friable, decay resistant. 13. Final cost of coal is $150.00 and above including pollution control costs, emissions costs, disposal fees and fuel costs versus e-coal with final cost of $60.00 nd below given carbon credits and other offsets. 14.
