Biogas and Bio Energy

National biogas and manure management programme

The Govt. of India launched National Project on Biogas Development i.e., National Biogas and Manure Management Programme in the year 1981. The programme was included in the Prime Minister's Twenty Point Programme in view of its importance to the rural areas.

Objectives
  • To provide energy in a clean, un polluting form for cooking
  • To make available enriched fertilizer as a by – product for supplementing and optimizing the use of chemical fertilizer
  • To reduce pressure on dwindling fuel wood supplies and prevent indiscriminate deforestation
  • To eliminate the smoke-filled cooking environment, reduce drudgery and prevent eye and lung diseases to rural women and children
  • To bring about improvement in rural sanitation.

Benefits

  • Tearless cooking and clean environment in the kitchen leading to healthier life for women and children
  • Provides nutrient rich manure
  • Saving of fossil fuels generating employment to rural workers
  • Each Biogas plant of 1 m 3 capacity saves about 1266 kgs of firewood or 222 liters of kerosene or 12 cylinders ( 174 kgs) of LPG per year

During 1840 year, some progressive farmers in Maharashtra have come to know that if dung is digested in anaerobic condition, the manure value is dung will be substantially improved apart from getting combustible gas for cooking and lighting. Scientists and technologists started work to designing a cheep and durable equipment/system for generation of Biogas and Appliances. KVIC has come out with a design for generation of Biogas with aerobic digestion. If contains two major segments viz., digester, a gas holder with guide frame and gas distribution system. Digester is made dorm the building material available in local area. Gas holder and other components are fabricated in work shop centrally and transported to the places where ever required. Subsequently a cheaper and effective model was developed by AFPRO called "Deenabandhu" which can be constructed with local materials like bricks, cement and sand and biogas generated using dung.

NEDCAP has started implementing the Biogas programme from the year 1982-83. The initial stages of implementation of the programme, 4 cum 6 cum capacity KVIC model biogas plants were constructed. It was observed that KVIC model biogas plants are comparatively expensive and need periodical maintenance. Since, 1990-91, the Corporation is popularizing the Deenabandhu model as it was found to be less expensive and more efficient. The programme gained momentum and the same model is continued. The Corporation has installed 2.50 lakhs above biogas plants so far.

Based on cattle population and dung availability in Andhra Pradesh State, the number of family-size biogas plants that can be installed are estimated at 10.90 lakhs. The cattle is mostly available in rural areas and the cooking energy required for farming community who possess cattle population should be met through generation of Biogas. Production of Biogas not only hygienically meets the cooking energy requirements of the farming community but also provides rich nitrogenous fertilizer.

The pre-requisites to construct the Biogas plants to the farmers/beneficiaries are

  1. Space to construct the Plant
  2. Water facility
  3. Cattle.
