Biochar

Choose the Correct Answer

Correct Answer : Option c

Explanation
Biochar has been in discussion in India’s climate policy framework, particularly with the upcoming Indian carbon market that is set to launch CO₂ removal technologies in 2026. Biochar is considered an important tool for carbon sequestration, soil health improvement, and waste management.

Statement 1 is correct: Biochar is indeed a type of charcoal rich in carbon, produced from organic material such as crop residues, forestry waste, and animal manure. Unlike conventional charcoal used for fuel, biochar is specifically intended for environmental benefits like soil enrichment and long-term carbon storage.

Statement 2 is correct: Biochar is made by heating woody crop residues and other forms of biomass in a controlled environment with little or no oxygen (pyrolysis). Feedstocks commonly include rice husk, corn stalks, sugarcane bagasse, and forestry slash.

Statement 3 is correct: The standard process for producing biochar is pyrolysis, where organic material is thermally decomposed at high temperatures in the absence (or near absence) of oxygen. This makes the carbon stable and prevents it from quickly returning to the atmosphere.
