Currently, daily cooking in Thma Sa is done with open fire and wood. As a result, large amounts of firewood are needed and cut in the area. To reduce this, BCDO is promoting small low-cost biogas installations as an alternative to the firewood to the villagers of Thma Sa. As a side product, the remains of the biogas process can be used as fertilizer for organic farming.
The pictures below illustrate the simpliciy of the biogas production, starting from the low-cost setup and the freely available cow dung or kitchen remains as the natural resource until the gas hub is working.
