Potential Renewable Energy from Landfill Waste and Refuse-Derived Fuel at Bantargebang

The Waste-to-Energy (WtE) and co-firing technologies are used for waste management in Indonesia. The Bantargebang Integrated Waste Management Site (IWMS) is a landfill that has already implemented WtE and industrial co-firing facilities in the form of Refuse Derived Fuel (RDF). The potential of Bantargebang IWMS for WtE and industrial co-firing materials is enabled due to the availability of raw materials in the form of Municipal Solid Waste (MSW) and Landfill Mining (LM), and facilities, such as the Waste Power Plant and RDF plant. Therefore, it is essential to study the chemical quality potential of raw waste materials and RDF products. This study aims to analyze the possible use of RDF for WtE in the industrial sector based on the chemical quality of RDF produced in Bantargebang IWMS. The results show that the Bantargebang IWMS via the Waste Power Plant offers WtE with a capacity of approximately 100 tons per day and an electricity output of around 750 kWh. The chemical quality analysis of MSW and LM raw materials indicated calorific values of approximately 1,943 kcal/kg and 2,415.98 kcal/kg, respectively, with 59% and 29% moisture content. This suggests that the raw waste materials processed in the Bantargebang IWMS meet the SNI 8966:2021 Class III quality standards for power plants. The Bantargebang RDF Plant has a processing capacity of 2,000 tons/day and produces approximately 700 tons/day of RDF. The processed waste was sourced from 1,000 tons of MSW and 1,000 tons of LM waste. The chemical quality analysis of RDF showed that it had calorific values of 2,962 and 4,289.6 kcal/kg. This indicates that the produced RDF is suitable for co-firing in the cement industry. PT Indocement Tunggal Prakarsa and PT Solusi Bangun Indonesia are the main off-takers of RDF produced from the Bantargebang IWMS.
