•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

ENVIRONMENTAL ADVANTAGES

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

Disadvantage

• Biomass has a smaller energy content for its bulk than fossil fuels• Costs of labor, transportation,

and storage would then be higher

• 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

APLLICATION BIO GAS PLANT

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.

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.
