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)
- 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.
