Environmental degradation has been on the increase due to an increase in anthropogenic activities to meet the demand of the geometric growth of the human population. This study conveys a sustainable idea of protecting the environment through the use of cheap and eco-friendly materials. The large volume of biomass waste in open spaces may cascade to deteriorate the environment and pose a serious public health risk. Pyrolysis converts biomass waste into valuable products like biofuels, biochar, and gas. Biochar is a solid product of biomass thermochemical conversion (pyrolysis) rich in carbon and open pores that is applicable to advancing environmental sustainability since it has multiple uses as carbon sequestration, soil fertility improver, and contaminant removal. Biochar largely contains carbon (C), making it a structurally stable natural storehouse of carbon, which can help reduce the emission of greenhouse gases (GHG) and mitigate climate change. Its addition to soil achieves improved soil fertility, water retention capacity, and the availability of major or micronutrients, serving as a soil enhancement for agri-food production. Biochar has the potential to remediate polluted soil as well as minimize the seepage of pollutants into groundwater, ensuring the protection of ecosystems and human health. Its pores, surface area and other physiochemical properties make it a potential material to be utilized for the purpose wastewater treatment since it adsorbs contaminants and remove pollutants from the water. It can also be pyrolyzed to obtain biofuel, and its use in transportation aligns with the sustainability goal since it reduces emissions and improves material.
