Question

Write short notes on the following.
(i) Biogas
(ii) Roof top rain water harvesting.


Solution

(i) Biogas:- Biogas is produced by processing residual waste from livestock (dung, manure and uneaten food), food production (fruit and vegetable waste, residues from meat, fish and dairy processing, brewery waste, food waste and much more) and effluents from industrial as well as municipal wastewater treatment plants. By constructing biogas power plants, agriculture assumes an important contribution to supplying energy from renewable resources as well as to the disposal of organic wastes. Digestates are produced as a by-product of biogas manufacturing, which can in turn be used as high-quality digestate.

(ii) Roof top rain water harvesting:- A water harvesting system in which rain falling on a roof is led through connecting pipes into a ferro-cement water collecting jar.
