Can dried cow dung really be burned?

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

In recent years, whether in the grasslands in northern Tibet or in the valleys in southern Tibet, the most surprising thing that Xinhua News Agency reporters found in various places is that the cow dung stoves used by local farmers and herdsmen for heating and cooking for thousands of years have gradually disappeared, while solar stoves powered by ethereal sunlight can be seen everywhere.

Now, in the rural areas of Xigaze and Shannan, Tibet, another kind of treasure that can be used as fuel and turned into organic fertilizer has appeared, that is, the solar biogas digesters being piloted and promoted by the Tibet Science and Technology Department in some parts of Tibet.

Tsering Ouzhu, a 63-year-old Tibetan farmer in Bailang County, Shigatse, was deeply impressed by biogas cooking. He said, "In the past, housewives had to sit around the stove all day, but now they don't need it." According to Tsering Ou Zhu, before biogas was used, villagers used cow dung to make fires. It was not only time-consuming but also time-consuming to stick cow dung on the wall to dry before making fires. The smoke from cow dung often made their eyes red-eyed.

Extended data:

Besides burning, cow dung can also be used as a raw material for producing chemicals. The technology developed by Osaka University in Japan that can efficiently convert methane into chemicals such as methanol is expected to become a new source of income for Hokkaido.

Methane produced by cow dung is mainly used for power generation, and methanol, as a raw material for the production of various chemical products, is gradually expanding. Located in the Sea of Okhotsk, Xingbu Town has concluded a cooperation agreement with Osaka University, and will start mass production technology development from the autumn of 20 19.

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