Mr. Xiem plans to raise 50 pigs in the near future so borrowed to build a 23 cubic-meter biogas digester. This investment will help him decrease the cost of cooking fuel, provide clean and safe fertiliser for his tea plantation, and especially, to avoid pollution.
Mr Xiem’s community still has many households that need to build biogas digester units because of the large number of livestock producers. Many areas do not have drains for animal waste, which is causing serious pollution problems for the families in that area.
