“…Some organic waste including food, dried leaves and woods. The high amount of organic materials in waste in the FDS may be dominated by the waste from the households, traditional markets, offices, hospitals (nonmedical), industry, garden/parks, hotels, schools, and tourism (3,10,11,15). While the least waste in the FDS is inorganic waste at around 36%.…”

“…On average, with a mechanical efficiency of 40%, the time for the anaerobic digestive-based WtE Plant to return relatively shorter capital than thermal technology is 1.13 years. At the end of the project period, WtE Plant's remaining equipment and buildings have a sale value of about 10% of their cost (3,26). Based on Table 1, the incineration technology provides greater economic benefits than other technologies.…”

“…On the other hand, 247 Final Disposal Sites (FDS) in Indonesia have been currently dominated by open dumping (26%), controlled landfill (25%), sanitary landfill (23%), semi-controlled landfill (3%), waste-toenergy (WTE) (1%) and unrecorded sites (22%). Based on the preliminary studies, the amount of waste in the Air Dingin FDS, Piyungan FDS, and Putri Cempo FDS has exceeded the maximum capacity limit, thereby potentially accelerating the lifetime of the landfill use and reduce the processing efficiency (3)(4)(5). This shows that waste management in the FDS currently cannot solve the waste problem and does not follow the Law No.…”

Introduction: Waste processing in Final Disposal Sites (FDS) in Indonesia is still dominated by open dumping. This condition causes health and environmental problems and inhibits the achievement of Sustainable Development Goals (SDGs) 2030. Waste is biomass that can be converted into electrical energy through the Waste-to-Energy Plant (WtE Plant) installation. This article aimed to illustrate the potential of WtE Plant in the FDS in Indonesia in supporting the achievement of SDGs 2030. Discussion: Most waste in the FDS are dominated by organic waste with the highwater content of 60-70% but have a calorific value almost equivalent to sub-bituminous coal. Most studies show the WtE Plant uses a thermal method (incinerator) than other technologies because it has a superior value in the technical aspects (easy operation and high generated energy around 9.86%), economy aspects (medium investment value, but high profit with moderate payback period around 6.5 years) environmental aspects (reduction of waste up to 70-80% and emissions), and lower public health impacts than those produced by open dumping and coal systems. For environmentally safe optimal results, it is necessary to reduce wastewater content, increase pollution control units, and implement an integrated monitoring system. Conclusion: The implementation of WtE Plant can accelerate to achieve the SDGs 2030, especially the 7th, 8th, 12th, and 13th goals concerning clean and affordable energy, decent jobs and economic growth, responsible consumption and production, and addressing climate change, respectively.

“…The right solution to reduce the increasing volume of waste is the construction of a Waste Power Plant (PLTSa). PLTSa is a type of new renewable energy in waste to energy (WtE) [15]. WtE utilizes the rest of human activities (in the form of waste) to be processed and used its heat energy to generate a boiler engine which is connected by a turbine and generator.…”

The city of Yogyakarta is the most significant waste contributor at the Piyungan Integrated Waste Disposal Site (TPST), Dukuh Ngablak. The need for land in landfill is getting higher and negatively impacts the environment, so processing waste into energy is one option. This study aims to answer whether the city of Yogyakarta is feasible in processing waste into energy. This study uses secondary data from the generation and composition of waste from the 2020 National Waste Management System. At the same time, the calorific value data is used from the literature study. The waste generation rate in 2020 in Yogyakarta City reached 0.09 kg/person/day. However, the waste generation produces a total dry weight of 274900.3 kg dry weight/day, while the complete potential energy recovery is 2290773.3 MJ/day. Therefore, the total calorific value of the Yogyakarta City waste generation is 6.37 MJ/kg, indicating a low value. This answers that waste processing with a thermal process is not suitable if applied with a mixture; therefore, high moisture waste must be separated first to produce a high calorific value.

A Techno-Economic Evaluation of Municipal Solid Waste (MSW) Conversion to Energy in Indonesia

Municipal solid waste (MSW) processing is still problematic in Indonesia. From the hierarchy of waste management, it is clear that energy recovery from waste could be an option after prevention and the 5R (rethink, refuse, reduce, reuse, recycle) processes. The Presidential Regulation No 35/2018 mandated the acceleration of waste-to-energy (WtE) plant adoption in Indonesia. The present study aimed to demonstrate a techno-economic evaluation of a commercial WtE plant in Indonesia by processing 1000 tons of waste/day to produce ca. 19.7 MW of electricity. The WtE electricity price is set at USD 13.35 cent/kWh, which is already higher than the average household price at USD 9.76 cent/kWh. The capital investment is estimated at USD 102.2 million. The annual operational cost is estimated at USD 12.1 million and the annual revenue at USD 41.6 million. At this value, the internal rate of return (IRR) for the WtE plant is 25.32% with a payout time (PoT) of 3.47 years. In addition, this study also takes into account electricity price sales, tipping fee, and pretreatment cost of waste. The result of a sensitivity analysis showed that the electricity price was the most sensitive factor. This study reveals that it is important to maintain a regulated electricity price to ensure the sustainability of the WtE plant in Indonesia.
