Abstract

Waste management in Jakarta is currently faced with a shortage of landfill space, and landfill mining could be a solution to this problem. The waste excavated from landfills can be utilized as compost, soil amendment, or RDF (refuse-derived fuel). This study aims to analyze the potential for landfill mining materials from two inactive zones of Jakarta's largest landfill, Bantar Gebang, and using those materials as compost and RDF. It was found that the material excavated from this landfill was dominated by soil-like materials (33–35%) and plastic (26–31%). The soil-like material had a 47–51% water content and a 4.42–6.23 C/N ratio, and it did not meet Indonesia's national standard for compost. The materials for RDF had 13–15 MJ/kg calorific values, 48–50% water and 24–27% ash contents, and a possibility of high chlorine emission. No RDF standard is currently available in Indonesia, but the materials did not meet the European standard. It is suggested that soil-like materials be used for soil amendment instead of compost; plastic waste and other combustible materials should be separated and dried to fulfill the RDF standard.
