(i) Biogas
(ii) Roof top rain water harvesting.
(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.
