“…In 2020, a total of 9,878 tonnes of MSW was burned at PLTSa Merah Putih producing electricity of 784 MWh, and 1,917 tonnes of fly ash and bottom ash (FABA), during 226 operation days [8]. While during the first semester of 2021, the pilot plant has been operated for 174 days, and a total of 5647.1 tonnes of MSW was burned to generate about 1,000 tonnes of FABA [9]. The generated FABA is disposed of as the landfill near the pilot plant.…”

Municipal solid waste incineration (MSWI) has been adopted in Indonesia to reduce the volume and mass of municipal solid waste. However, as a by-product of waste combustion, fly ash generation cannot be avoided. It can cause an environmental problem if not managed properly. Hence, this study aims to investigate the characteristics of fly ash generated from Indonesia’s first waste-to-energy incineration pilot plant and its potential utilization. Fly ash was characterized using X-Ray fluorescence (XRF), BET surface area measurement, pore size distribution (PSD), scanning electron microscopy with energy-dispersive spectrometry (SEM-EDS), and X-ray diffraction (XRD). The characterization results showed that calcium was predominant, around 28%, followed by titanium, silica, iron, and aluminum, with values of 7.10%, 5.70%, 4.40%, and 4.30%, respectively. These results demonstrated that MSW incineration fly ash was classified as a very active high-calcium fly ash. The surface structure of fly ash was flaky and complex, with some irregular material. The particle size distribution of fly ash shows that the diameters of most particles were nearly 12 μm. The specific surface area of fly ash was 3.06 m2/g, the total-pore volume was 0.01 cm3/g, and the average pore size was 11.82 nm. In addition, the environmental risk assessment was evaluated using the toxicity characteristic leaching procedure (TCLP). TCLP concentrations of heavy metals, including arsenic, barium, beryllium, cadmium, chromium hexavalent, copper, lead, mercury, nickel, selenium, and zinc, were lower than the regulatory level, indicating a low environmental risk. Therefore, it has great potential for utilization as a paving block mixture material.

Rapid population increase, coupled with increasing urbanisation and industrialisation, is expected to create substantial demand for waste-to-energy (WtE) facilities in Indonesia. While the Indonesian government is working towards proper and economic handling of waste, there is a need to move beyond traditional incineration processes to more advanced WtE technologies in order to mitigate the adverse environmental impact. Along with this, a proper waste sorting system also needs to be established to improve the functioning of WtE facilities. However, challenges persist, including high capital costs, limited waste feedstock availability, and social acceptance concerns. Additionally, worries have been raised regarding the environmental and health impacts of WtE facilities, particularly their potential emissions of pollutants such as dioxins and furans. Overall, while WtE holds the potential to contribute to sustainable waste management and renewable energy development in Indonesia, careful planning and management are essential to ensure environmental, social, and economic sustainability. This study employs the Policy Effectiveness Assessment, guided by the Policy Implementation Theory, to evaluate WtE policies in Indonesia. By examining the intersection of environmental sustainability and socio-economic factors, the article aims to provide valuable insights into the effectiveness of current WtE policies. Through combining environmental, socio-economic, and technological perspectives, the article strives to offer a nuanced understanding of the challenges and opportunities, paving the way for informed policy decisions and sustainable waste management practices in the country.
