Biochar

Biochar Latest News

The Indian carbon market set to be launched in 2026, CO2 removal technologies such as biochar are expected to play a crucial role. 

About Biochar

• Biochar is a type of charcoal rich in carbon and is produced from agricultural residue and organic municipal solid waste.
• It offers a sustainable alternative to manage waste and capture carbon.
• It is granular material obtained by heating crop residue at 400°C to 600°C in a kiln-shaped structure in the absence of oxygen.
• Advantage of Biochar: It can hold carbon in the soil for 100-1,000 years due to its strong and stable characteristics, making it an effective long-term carbon sink.

Potential Applications of Biochar

• Agriculture: Applying biochar can improve water retention, particularly in semi-dry and nutrient-depleted soils. This, in turn, can abate nitrous oxide emissions by 30-50%.
• Biochar can also enhance soil organic carbon, helping restore degraded soils.
• Industries: In carbon capture applications, modified biochar can adsorb CO₂ from industrial exhaust gases. However, its carbon removal efficiency is currently lower than that of conventional methods.
• Construction sector: Biochar can be explored as a low-carbon alternative to building materials and makes building materials a stable carbon sink.
• Wastewater Treatment: Biochar offers a low-cost and effective option to reduce pollution.
