Toward Zero Waste: Waste Pickers Running Biogas Plants in Mumbai, India | Other Worlds

Toward Zero Waste: Waste Pickers Running Biogas Plants in Mumbai, India | Other Worlds.

Classic example of waste creating real jobs for those who really need it (low-income group female waste pickers) in a city which badly needs (organic) waste management (Mumbai)

Kudos to NGO, Stree Mukti Sanghatana (SMS) for bringing to existence, Parisar Vikas (PV) program to train informal recyclers as “parisar bhaginis,” or “neighborhood sisters.”

A key innovation in PV’s model is the adoption of a locally viable technology for biogas creation, called the Nisargruna Biogas Plant.

Plant operation is relatively simple as the technology was designed to be used by non-skilled workers. (More on this in the above article)

Benefits:

  • Unlike composting operations, a biogas plant does not create unpleasant decomposing odors
  • Does not take up a large amount of space – Only 50 m2 are required for a plant that processes 100 kg per day.
  • The resulting biogas is 85 percent methane, more efficient than the 50 percent methane typical of most biogas plants, which SMS attributes to Nisargruna’s two-step aerobic/anaerobic process.
  • Reduces the need for waste pick up, transport, and disposal, as well as the pollution associated with these activities. It also avoids the pollution that results from landfilling wet waste: methane emissions, toxic leachate, and odors.

    • Commendable effort! I was impressed by this fact quoted: ‘The AD facility at Emerald Biogas can process card, plastics and other materials often associated with waste from supermarkets, fast food outlets, businesses and schools. The heavy duty depackaging process can handle the more difficult waste streams such as supermarket waste, which is often triple packed and manufacturing waste streams.’
