Answer: Agricultural residue and organic municipal solid waste
Notes: The Indian Carbon Market is set to launch in 2026, with carbon dioxide (CO₂) removal technologies like biochar playing a key role. Biochar is a carbon-rich charcoal made from agricultural residue and organic municipal solid waste. It is produced by heating crop residue at 400°C to 600°C in a kiln without oxygen. Biochar can store carbon in soil for 100-1,000 years, acting as a long-term carbon sink. In agriculture, it improves water retention, restores degraded soils, and reduces nitrous oxide emissions by 30-50%. In industries, modified biochar can capture CO₂ from exhaust gases, though efficiency is lower than conventional methods.
