As a renewable energy source, biogas has gained considerable importance, especially in the last decade in many countries. Currently, there are approximately 7,000 facilities operating in Germany with a total electric power of 2.8 Gigawatts. The electrical energy produced by these plants is equivalent to the production capacity of the average size of two and two nuclear power plants. In other words, electricity needs of 13% of all private houses can be met by biogas.
Biogas is a flammable gas obtained from biomass processing. Biogas is derived from only animal or vegetable, organic raw materials, unlike other combustible gases (eg natural gas): Biological wastes, organic wastes from food industry, energy crops such as corn or sugar beet, and animal feces formed in animal husbandry can be used as substrates in biogas plants..
Dairy wastes are the best and free sources of fuel available in-house thus these are the most suited industries for biogas production. The cost of producing biogas energy is very minimal. Pakistan is the 5th largest milk producing country means have one of the largest cattle herd in the world and with emerging Dairy Farmers the biogas plants can fulfill their energy needs with the animal waste that they produce. New controlled dairy farms consume more electricity as compared to conventional dairy sheds. As these farms are located in the remote areas so they face electricity shortage power outages. Biogas produced from Cow/Buffalo dung can replace high-cost Diesel electricity production.
Revgreen Pakistan has successfully finished and monitoring many projects. in Lahore, Islamabad, Karachi, sheikhupura, and in many villages as well.
