What is Sewage sludge derived biochar and its potential for sustainable environment in circular economy: Advantages and challenges about?

With the increase in population and wastewater generation, the management of solid by-products, including sewage sludge (SS), has become a challenge. This article reviews various advantages and challenges associated with the use of sewage sludge-derived biochar (SSDB) and its potential for application in environmental improvement toward the attainment of circular economy. SS is a semi-solid mixture of various components, including potentially toxic elements (PTEs), generated as a by-product from wastewater treatment plants. The economic feasibility associated with SS management is a primary challenge for wastewater treatment plants. The utilization of bio-waste after conversion into biochar is gaining impetus considering its application potential in various fields. Biochar is rich in organic matter and nutrients. Its highly porous structure makes it an attractive alternative to traditional waste management methods. The properties of biochar, especially sludge-derived biochar, are greatly affected by various factors such as residence time, moisture content, pyrolysis temperature, heating rate, etc. This paper reviews recent emerging fields of application for SSDB, including water an
