![]() In this regard, developing and populous countries may support economic growth by utilizing low-cost methods for producing biochar and employing it in local agriculture. This quantity will rise to about 138 Mt DS sewage sludge and 16985 Tg CO 2-eq emissions in 2050, a 20% increase. According to estimations, the worldwide SS output and associated CO 2-eq emissions were around 115 million tons dry solid (Mt DS) and 14,139 teragrams (Tg), respectively, in 2020. The worldwide potential of SS output and CO 2-equivalent emissions in 2050 were predicted as factors of global population and common disposal management in order to create a futuristic strategy and cope with the quantity of abundant global SS. Additionally, the preparation of SSB has an increased ash content, a lower yield, and a higher surface area as a result of the rise in pyrolysis temperature. Lower hydrogen/carbon ratios in SSB generated at higher pyrolysis temperatures point to the existence of more aromatic carbon molecules. Comparing the features of SSB obtained at various pyrolysis temperatures revealed changes in its elemental content. ![]() The preparation of sewage sludge biochar (SSB) and its impacts on soil characteristics, plant health, nutrient leaching, and greenhouse gas emissions (GHGs) are critically reviewed in this study. ![]() Assessing the risk of various disposal techniques can be quite useful in recommending appropriate management. Sewage sludge (SS) has been connected to a variety of global environmental problems. ![]()
