Abstract

River debris is the main problem from the negative impact of poor waste management. The composition of river debris in Jakarta consists mostly of plastic waste. Plastic waste from river debris has an opportunity for energy recovery. This study aimed to see the potential for utilizing river debris in energy recovery in power plants. This research was conducted at three sampling shelter points in Pesing, Pluit, and Perintis. Waste generation and composition were quantified using the load count method on Indonesian state standards for seven consecutive days. River debris generation in Pesing, Pluitm, and Pernting averaged 7.2; 3; and 1.8 tons/day. More than 60% (w/w) of plastic bag waste was found in the Pesing and Pluit shelters, while 67.3% was found in the Perintis shelter. Based on the calorific value of each plastic waste, the energy potential from plastic waste recovery can reach 16,197,109 kWh/year. This is equivalent to an electricity supply of 0.05% of the total electricity demand in Jakarta.

Abstract

Marine debris in Jakarta is a complex problem because the amount is too large every day. Addressing this critical gap, this study proposes a model for efficient waste transportation through the development of an Intermediate Transition Station (ITS) system. This system not only facilitates the effective movement of waste but also incorporates a recovery process to reduce the volume of debris before it reaches the landfill. The ITS serves as a pivotal node in the waste management network, ensuring the continuity of waste flow from accumulation points to processing facilities. With the ITS, the total marine debris managed amounts to 39.96 tons/day, of which 9.33 tons/day is recovered, leaving a significantly reduced residue of 25.63 tons/day or 1.134 m3/day for landfill disposal. Implementing the Haul Container System (HCS) within this framework, the study demonstrates that waste transportation from the ITS to Jakarta's Bantar Gebang Integrated Waste Processing Site can be streamlined to just 3 trips/day. By providing a structured and strategic approach to marine debris transportation, the ITS model aims to prevent the re-pollution of Jakarta's water bodies and significantly reduce the carbon footprint by 67.2% from current conditions, thereby offering a sustainable solution to this pressing urban environmental challenge.
