It can be burned, but now the cow dung stove has faded out of the farm and replaced it with biogas stove.

In recent years, no matter in the grassland in northern Tibet or in the valley in southern Tibet, the most surprising thing that Xinhua News Agency reporters found everywhere was that the cow dung stoves used by local farmers and herdsmen for heating and cooking for thousands of years gradually disappeared, while solar stoves with ether sunlight as energy source were everywhere.

At present, another treasure that can be used as fuel and turned into organic fertilizer has appeared in the rural areas of Xigaze and Shannan in Tibet, that is, the solar biogas digesters that are being piloted and promoted in some parts of Tibet by Tibet's science and technology departments.

Tsering Ouzhu, a 63-year-old Tibetan farmer in Bailang County, Shigatse, is deeply impressed by biogas cooking. He said, "In the past, housewives had to stay around the stove all day, but now they don't need it." According to Tsering Ou Zhu, before the use of biogas, the villagers always used cow dung to burn the fire, and they had to stick cow dung on the wall to dry it for the fire, which not only wasted labor and time, but also made the smoke from cow dung often make them jealous and sore.

Extended information:

Cow dung can be used as raw materials for chemical products besides combustion. The technology developed by Osaka University in Japan, which can efficiently convert methane into chemicals such as methanol, is expected to become a new source of income in Hokkaido.

methane produced by cow dung is mainly used for power generation, while methanol is used as raw material for producing various chemical products, and its use is gradually expanding. Located on the coast of the Sea of Okhotsk, Xingbu Town has concluded a cooperation agreement with Osaka University, and mass-produced technology development will begin in the autumn of 219.

In Hokkaido, where the dairy industry is developed, the technology of fermenting the feces and urine of livestock and then using the methane generated from it to generate electricity is becoming popular.
