Abstract
This mini-review, enhanced with a bibliometric analysis, explores biochar production via sewage sludge pyrolysis and its diverse applications, employing a bibliometric method to map the scientific landscape and key research impacts. It outlines the pyrolysis technique, a process converting sewage sludge into biochar by heating in an oxygen-free environment, which minimizes waste while producing valuable biochar. The review assesses biochar’s characteristics-like its large surface area and porosity-beneficial for soil improvement, water filtration, carbon storage, and contaminant removal. It addresses production challenges and environmental benefits, urging further research to fine-tune pyrolysis and broaden biochar’s uses across various sectors.
