This document discusses biomass energy and biogas plants. Biomass is a renewable energy source derived from living or recently living organisms, including wood and plant or animal waste. Biomass can be used to generate electricity or produce heat through combustion, torrefaction, pyrolysis, or gasification. Biogas plants are discussed as an application of biomass energy. Biogas plants have advantages such as using cattle waste as a steady fuel source, reducing deforestation, and providing rural sanitation benefits. Biogas can be used for cooking, lighting, running pumps or generators, and producing electricity.

2. •Biomass is a renewable energy source that is derived
from living or recently living organisms.
•Biomass includes biological material, not organic material
like coal.
•Energy derived from biomass is mostly used to generate
electricity or to produce heat.
•Thermal energy is extracted by means of
combustion, torrefaction, pyrolysis, and gasification.
•Biomass can be chemically and biochemically treated to
convert it to a energy-rich fuel.
OVERVIEW

4. ENVIRONMENTAL
ADVANTAGES
•Renewable resource
•Reduces landfills
•Protects clean water supplies
•Reduces acid rain and smog
•Reduces greenhouse gases
•Carbon dioxide
•Methane

5. Disadvantage
• Biomass has a smaller energy
content for its bulk than fossil
fuels
• Costs of
labor, transportation, and storage
would then be higher

7. • RESOURCES OF BIOMASS
SUBSTANT
•Comes from the forest
•Can also come from plant and animal waste
•Wood and waste can be found virtually
anywhere
•Transportation costs

8. APLLICATION
BIO GAS PLANT

10. Advantages of bio gas plant
(a) Large cattle population in the countryside
ensuring steady source of supply of the raw
material required for running the gas plant.
(b) Helps in reducing the deforestation as it
arrests for cutting of trees for firewood.
(c) Helps in maintaining ecological balance.
(d) Helps in rural sanitation
(e) Lower capital cost and almost cost free
maintenance.
(f) Removes drudgery of women.

11. Uses of Gobar Gas
Generally the uses of the gas can be as
under 1) cooking
2) lighting
3) Motive Power a) run pump set b) chalf-
cutter
4) can produce electricity.
Motive Power can be produced by linking
the Gobar Gas to a duel fuel
engine, specially designed for Gobar Gas.
