**2. Conclusion**

The chapter explored the possibility of using biochar from agricultural wastes as a suitable alternative for the remediation of environmental pollutants, soil conditioning and the long-term biochar application in the environment. Agricultural wastes biochar can ensure environmental safety and sustainability. Minerals biochar can significantly impact biochar attributes therefore, the type and amount of minerals in biomass must be optimised for the intended environmental application. Biochars have made substantial breakthroughs in reducing greenhouse gases emissions, reducing soil nutrient leaching, sequester atmospheric carbon into the soil, increasing agricultural productivity, and reducing bioavailability of environmental contaminants. Biochar has been widely known for its ability to serve as remediator of contaminant, plays a vital role climate change mitigation and bioenergy production. The incorporation of biochar into the soil improves plant health and crop productivity.
