  • Biogas will make a convenient alternative to alleviate the energy crisis in the farm sector including farmers' households, apart from providing a good quality manure devoid of viable seeds of weeds.
  • Biogas is generated through the anaerobic digestion of organic wastes mainly cattle dung. An average Indian farm family normally has two or three cattle for basic agricultural operations.
  • The dung from these animals can be efficiently used. Increased popularization of biogas plants has led to about 16 lakh family - type biogas plants in India, starting from a meagre 1000 plants approximately in 1972-73. In Tamil Nadu state alone there are about 1. 5 lakh number of biogas plants.
