Here is LH Agency's Effort to Extend Service Life of Bantargebang Landfill
Reported by Toni Riyanto | Translated by Nugroho Adibrata
The Jakarta Environment (LH) Agency already has several steps to optimize the Bantargebang Landfill in Bekasi, West Java, which was previously predicted to reach maximum capacity this year.
Landfill Mining is an approach used to develop the capacity of the Bantargebang Landfill in extending its service life
Those several steps are through landfill mining that is no longer active and the construction of a Waste Power Plant (PLTSa).

Landfill mining continues to be conducted at the Bantargebang Landfill with the potential to provide benefits in the provision of land that can be reused and the utilization of the waste mining results, which are used as fuel for the cement industry.
LH Agency Acting Head, Syaripudin said that the waste entering the Bantargebang Landfill was still high. He assessed, the height of the zone is getting more ideal. Moreover, the availability of land is decreasing.
"Landfill Mining is an approach used to develop the capacity of the Bantargebang Landfill in extending its service life," he expressed, Thursday (7/1).
He explained it is an inactive zone of landfill mining with the characteristics of waste that has been decomposed to be reused thus it can extend the landfill's service life in the hope that it could be used for other environmental purposes.
"Old piles of waste from landfills have the characteristics of decomposed waste. Generally, the remaining material has a high calorific value, making it ideal for processing one of them into alternative fuels," he explained.
He went on to say that the main purposes include space conservation and extending the life of the landfill, elimination and mitigation of potential sources of contamination, energy recovery, and material recycling.
"It also aims at reductions in cost management systems and development or land reuse," he continued.
He added that efforts to optimize the landfill were also executed with the construction of a Waste Power Plant (PLTSa), which is a collaborative project between the Agency for the Assessment and Application of Technology (BPPT) and the Jakarta administration, which is currently a pilot project in Indonesia.
PLTSa is included in the National Strategic Project (PSN), according to Presidential Regulation (Perpres) number 58/2017 on National Strategic Infrastructure Projects.
Its implementation was set in Perpres number 35/2018 on the Acceleration of Construction of Waste Processing Installations into Electrical Energy based on Eco-friendly Technology whose implementation will be prioritized in 12 major cities in Indonesia, one of which is Jakarta
"PTLSa Merah Putih is the first waste power plant in Indonesia," he explained.
He expressed that it was designed to operate continuously 24 hours per day. It uses waste fuel with 700 kW capacity for the internal operation of the PLTSa unit.
It also benefits the availability of alternative waste processing, which is able to reduce waste significantly, quickly, eco-friendly, and can generate electricity.
Then another benefit is to gain learning in thermal waste processing or incinerators for implementation in similar large-scale waste processing facilities in the future.
"This is in line with the vision of the Bantargebang Landfill as a research and study center for solid waste," he uttered.
