Tibet builds 114,000 biogas pits since 2006


A total of 114,000 biogas pits have been built in its rural areas since Tibet launched a biogas pits construction project in 2006.

According to a plan of the central government, 155,705 pits should be built at an investment of 65,926 yuan (9,651 U.S. dollars) in 53 counties of Tibet, said Du Jie, deputy director of Tibet's Agriculture and Animal Husbandry Department.

To date, nearly 570,000 households of farmers and herdsmen have acquired access to the use of this clean and convenient engergy, which in turn help them with an improved living.

Daily life use of biogas has changed somewhat Tibetan farmers and herders' traditional, old way of life. Whereas, mostly in the countryside of Tibet, humans used to share dwelling spaces with livestock, they now enjoy a separate, clean living environment by using biogas energy.

Meanwhile, the use of biogas has converted the "three wastes" -- straw, dung and garbage into "three treasures" -- fuel, animal feed and fertilizers, bringing about great economic and environmental benefit.

The users have also channelled biogas to greenhouses to grow vegetables for sale to increase their income as well as for balanced diet. The existing 2.28 million square meters of greenhouse supported by the 114,000 pits are estimated to reap 20 million yuan (2.93 million U.S. dollars) in income within years.

Besides, using biogas instead of cutting trees for fuel is especially significant for protecting Tibet's fragile eco-environment.
