Biochar, long valued for its role in soil enhancement and carbon sequestration, is now gaining momentum across diverse industries such as construction, waste management, textiles, and renewable energy. This talk explores how biochar is evolving into a scalable, carbon-negative solution aligned with ESG goals. Drawing on techno-economic analysis and global case studies, we identify key commercialisation barriers—such as inconsistent standards and policy gaps—and propose solutions including life cycle assessments, inclusive governance models, and region-specific pyrolysis technologies. A coordinated effort across government, industry, and academia is essential to unlock the full environmental and economic potential of biochar filters.
