“…Biogas is the combination of different gases that can be used as fuel in a fuel cell (Abdalla et al, 2018;Afif et al, 2016;Afroze et al, 2020bAfroze et al, , 2020aAfroze et al, , 2019Radenahmad et al, 2016). Finally, the solid residue is the biochar which can be converted into activated carbon (Morni et al, 2018). Using the same precursor, different types of ACs can be produced by activating agents under different operating conditions (Yusuff, 2019).…”

Without pure water, it is impossible to survive for any living beings. The ratio of freshwater on our planet is very poor and the demand is increasing with time for the growing population. Furthermore, water is being contaminated by industrial and agricultural activities, pharmaceuticals, technocratic civilization, pesticides, garments, global changes etc. In addition to this, environmental pollution and global warming are swelling due to the greenhouse and harmful gases generated from the dumping and burning of fossil fuel. Addressing these problems, it is necessary to find out the cost-effective and environmental friendly processes to purify the contaminated water and air. Activated carbons (ACs) are one of the best solutions for removing the pollutants from aqueous and atmosphere as it is the carbonaceous materials with a high degree of porosity, well-developed surface area, and distinguished functional groups which are required for elimination of contaminants. The preparations of activated carbon are easy and safe processes, mainly from the pyrolysis or gasification of biomass with heat and/or chemicals. The recycling and regeneration of activated carbon after use are also essential for resource maintenance and environmental safety. Thus, AC can protect the ecosystem in a double direction by purifying the water and air from the pollutants.
