Biochar technology presents a promising pathway for carbon sequestration and waste management in India. However, its large-scale implementation faces significant challenges. Critically analyze the potential of biochar in India's climate strategy while examining the barriers to its adoption.

Introduction

Biochar, a carbon-rich charcoal produced from agricultural residue and organic waste, emerges as a sustainable solution for India's dual challenge of waste management and carbon sequestration. With India's carbon market launching in 2026, biochar technology offers multisectoral applications that align with the country's climate commitments and development goals.

Potential of Biochar Technology in India

• India generates over 600 million metric tonnes of agricultural residue and 60 million tonnes of municipal solid waste annually, providing abundant raw material for biochar production
• Utilizing 30-50% of surplus waste can produce 15-26 million tonnes of biochar, removing 0.1 gigatonnes of CO2-equivalent annually
• Byproducts include syngas (20-30 million tonnes) and bio-oil (24-40 million tonnes), potentially generating 8-13 TWh of electricity and offsetting 8% of diesel/kerosene production
• Agricultural applications improve soil water retention and reduce nitrous oxide emissions by 30-50%, crucial since N2O has 273-times the warming potential of CO2
• Construction sector applications show biochar-enhanced concrete can capture 115 kg of CO2 per cubic meter while improving mechanical strength by 20%
• Wastewater treatment potential exists with 1 kg biochar treating 200-500 litres of wastewater, addressing India's 72% untreated wastewater challenge

Barriers to Large-scale Adoption

• Absence of standardized feedstock markets and consistent carbon accounting methods undermines investor confidence
• Limited awareness among stakeholders and weak monitoring, reporting, verification frameworks
• Lack of coordination across agriculture, energy, and climate policy sectors
• Insufficient policy support and unclear business models for commercial viability
• Market uncertainties and evolving technologies create deployment challenges

Conclusion

While biochar offers significant potential for India's climate strategy through carbon sequestration, waste management, and rural job creation (approximately 5.2 lakh jobs), its success depends on systematic policy integration, standardized frameworks, and coordinated stakeholder support. Strategic implementation can transform biochar from a promising technology into a scalable climate solution.
