- To overcome decline in air quality in Delhi issue, India is testing Swedish technology — torrefaction that can convert rice stubble into ‘bio-coal’.
- The government has funded a pilot project at the National Agri-Food Biotechnology Institute in Mohali (Punjab) with a Swedish company to evaluate the feasibility of the technology.
- Torrefaction is a thermal process to convert biomass (at 250 degrees celsius - 350 degrees celsius) into a coal-like material, which has better fuel characteristics than the original biomass.
- Advantages - Torrefied biomass is more brittle, and less energy-intensive. It will reduce CO2 emissions by 95%.
- It has lower sulfur and ash content (compared with coal), etc.
