The agroindustry byproducts when mixed with cowdung can be used for the generation of biogas. The biogas generated can be further compressed and desulphurised to produce BioCNG. The BioCNG produced can be used as fuel in vehicles alternate to petrol and diesel. This will be very ecofriendly and economical technology.
