Way of harness of biomass energy
Solid biomass, such as wood and garbage, can be burned directly to produce heat. Biomass can also be converted into a gas called biomass or into liquid biofuels such as ethanol and biodiesel. These fuels can then be burned for energy.
Biogas forms when paper, food scraps, and yard waste decompose in landfills, and it can be produced by processing sewage and animal manure in special vessels called digesters.
Ethanol is made from crops such as corn and sugar cane that are fermented to produce fuel ethanol for use in vehicles. Biodiesel is produced from vegetable oils and animal fats and can be used in vehicles and as heating oil.
