APPLICATION OF BIOCHARS BASED ON SEWAGE SLUDGE FOR ENVIRONMENTAL PROTECTION PURPOSES

Biochar obtained from sewage sludge is considered one of the most interesting end products in a closed-loop economy based on wastewater. In the study, biochar samples were obtained, physicochemical and sorption characteristics of the obtained material were determined. A comparative analysis of the characteristics of biochars based on sewage sludge and coals obtained by carbonization of birch and pine sawdust was carried out. It was found that biochars obtained from various wastes (sawdust of woody plants and sewage sludge) exhibit comparable sorption capabilities with respect to the organic dye methylene blue.
