Work began on the construction of 10 domestic biogas plants, which will supply energy for cooking and lighting to 10 households. The plants will convert cow dung into biogas, and produce a rich fertiliser as a by-product. The underground plants will be largely built from interlocking mud bricks which use locally available material (earth and water) plus a little cement. The fact that they interlock will massively reduce the amount of cement mortar needed for construction. And the brick making machine is manually operated.
