biomass containsa stored energy justify. how does bio gas plant help to reduce the problem of pollution
Answers
Answer:
Explanation:
bio-mass contains stored energy as:
(i) Biomass (animal and plant products) is used to form biogas
(ii) Biomass does not have a good heating capacity, it produces a lot of smoke
Cow dung, various plant materials like residue after harvesting the crops, vegetable waste and sewage are decomposed in the absence of oxygen to give biogas
Biogas is stored, and drawn through pipes for use
It is an excellent fuel, gaseous state, non-polluting and high heating capacity
The slurry left behind can be used as manure, rich in nitrogen and phosphorus
(b) Biogas reduces pollution in the following ways:
It burns without smoke, leaves no residue like ash in wood, charcoal and coal burning.
It provides a safe and efficient method of waste disposal, besides supplying energy and manure.
Biomass is formed from the dead or living organic waste. All the energy stored by an organisms body is the part of energy stored in biomass.In bio gas plant the organic waste like cow dung, plants waste like fallen leaves, branches etc. undergo breakdown by microbes in a digester tank. This results in the production of bio gas and a manure.
Explanation:
Biomass is the best source of energy but if it is directly burnt it causes pollution.
In bio gas plants the biomass of animals as well as plants under go breakdown process that produce bio gas and the residue is used as manure.
In this way bio gas plant plays a major role in reducing pollution.
