Compressed Biogas and SATAT

About Biogas

  • Energy is produced from organic waste. Converted into energy by direct combustion or by conversion of such wastages into alcohol, methane, or other storage fuels.
  • Bio-gas is produced naturally through the process of anaerobic decomposition from waste and bio-mass sources like agriculture residue, cattle dung, municipal solid waste, farms, gardens, kitchen waste, night soil waste, sugarcane press mud, sewage treatment plant (STP) waste, etc. It contains 60-65% Methane, 35-40% CO2, 0.5-1% H2S and rest is water vapour.
  • Gases emitted from Biogas = Methane (60-65%), CO2 (35-40%), Hydrogen Sulphide (0.5-1%), Ammonia and the rest is water vapour.
  • National Biogas and Manure Mgt Prog (NBMMP)
    1. It is a Central Sector Scheme. Setting up of Family Type Biogas Plants mostly for rural and semi urban areas.
    2. Under MNRE and implemented by State nodal Agencies, KVIC, BDTCs.
  • GOBARDHAN (Galvanizing Organic Bioagro Resource Dhan) Yojana
    1. To convert waste into Biogas & compost. = Benefit people + clean village + helping rural people especially women.
    2. Kerala installed 1st Biogas plant under Gobardhan Yojana.

Compressed Biogas (CBG)

  • CBG is similar to commercially available natural gas in its composition and energy potential.
  • It is produced naturally through a process of anaerobic decomposition from waste/bio-mass sources like agriculture residue, cattle dung, municipal solid waste etc.
  • After purification, it is compressed and called CBG, which has pure methane content of over 90%.
  • CBG can be used as an alternative, renewable automobile fuels & it is marketed through OMCs. It can also replace CNG in automotive, industrial and commercial uses.
  • CBG to be brought under Priority Sector Lending.
  • CBG potential is high in Tamil Nadu.

SATAT initiative (Sustainable Alternative Towards Affordable Transportation)

  • Under MoPNG. To set up Compressed Biogas (CBG) production plants. It has 4 objectives:
    1. Utilising > 62 million metric tonnes of waste generated every year in India,
    2. Cutting down import dependence,
    3. Supplementing job creation in the country, and
    4. Reducing vehicular emissions and pollution from burning of agricultural/organic waste.
  • Benefit both vehicle users - farmers & Entrepreneurs.
  • Promise for Municipal SWM & tackle Air Pollution.
