"There are many advantages to biogas technology for people living in the rural areas of a developing country. A biogas plant can digest materials that are readily available on small farms, such as animal dung and crop wastes. Biogas digestion not only produces a clean, high-grade fuel gas, it also gives a residue that is a good fertilizer. Biogas can also be used in engines to drive machinery and water pumps."
