Bio-Energy*

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 
earth’s 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.
