2. ENERGY TECHNOLOGY Biomass origin - Resources – Biomass estimation. Thermochemical conversion – Biological conversion, Chemical conversion – Hydrolysis & hydrogenation, solvolysis , biocrude , biodiesel power generation gasifier , biogas, integrated gasification.

3. Biomass Biomass is plant or animal material used as fuel to produce electricity or heat. Examples are wood , agricultural residues and waste from forests , waste from industry, yards or farms and households.

4. Biomass origin Biomass contains energy  first derived from the sun Plants absorb the sun's energy through photosynthesis, and convert carbon dioxide and water into nutrients (carbohydrates). The energy from these organisms can be transformed into usable energy through direct and indirect means

5. Biomass Resources

6. Biomass Resources Agricultural Residues Animal Waste Forestry Residues Wood Wastes Industrial Wastes Municipal Solid Wastes and Sewage

7. How is biomass energy generated? Most electricity generated from biomass is produced by  direct combustion . Biomass is burned in a boiler to produce high-pressure steam. This steam flows over a series of turbine blades, causing them to rotate. The rotation of the turbine drives a generator, producing electricity.

8. What are the types of biomass energy? We use four types of biomass today Wood and Agricultural Products Solid Waste Landfill gas and Biogas Alcohol fuels (like Ethanol or Biodiesel) .

9. Why biomass is the best energy source? Biomass is always and widely available as a renewable source of energy. It is carbon neutral. It reduces the overreliance of fossil fuels . Is less expensive than fossil fuels . Biomass production adds a revenue source for manufacturers . Less garbage in landfills.
