The importance of biochar & its role in carbon sequestration is growing as a climate mitigation strategy. Produced through the pyrolysis of organic biomass, biochar is a stable carbon-rich material that enhances soil fertility, improves water retention, and reduces methane and nitrous oxide emissions from soils. Scientists are optimizing biochar properties to maximize its carbon sequestration potential and its effectiveness in pollutant remediation. Integrated biochar systems in agriculture and bioenergy are creating sustainable waste management solutions while reducing atmospheric CO? levels. As global climate policies focus on carbon reduction, biochar is emerging as a vital tool for sustainable environmental management.
