Abstract: In a country like India, the number of people migrating to the urban areas is immeasurable and the amount of waste that is generated from various domestic and industrial activities is enormous. In India, due to lack of ability of the policy & legal instruments, limited financial assistance and inadequate technology, Solid Waste Management (SWM) is a multidimensional and rather demanding task. As per data released by the Central Pollution Control Board (CPCB), 70% of the sewage sludge generated in urban India is not treated and is disposed in an unsustainable manner. Sewage sludge continues to pose threats to the environment and human health in terms of the volume that is generated and the improper disposal techniques. Carbonization of sewage sludge is considered to be a promising technique for sludge volume reduction as well as providing us with an opportunity to utilize it for energy production and other alternative applications. Results of this study have shown that sewage sludge can be successfully carbonized to produce a bio-char, which can be used as an energy source or as an adsorbent for various environmental applications.
Keywords: carbonization, utilization, sludge, adsorption.
