Jakarta. Jakarta's city administration has pledged to accelerate the construction of intermediate waste treatment facilities to convert waste to energy at four locations across the capital as the city's Bantargebang landfill in West Jawa would reach its full-capacity next year. 

"We want to look for breakthroughs in waste management and need to immediately improve ITF development in several points in the Jakarta area," Ahmad Riza Patria, Jakarta's deputy governor, said on Sunday. He was referring to the waste treatment facilities by its abbreviation.  

According to Jakarta's Waste Management Masterplan for 2012-2032, the city would build four ITFs in Sunter and Marunda in North Jakarta, in Cakung, East Jakarta, and Duri Kosambi in West Jakarta.

Still, the progress had been slow. The city broke the ground for Sunter facility in December 2018, but the construction has yet to start, due to financing and regulatory problems.

Under the plan, the ITFs might use incinerator, gasification, pyrolysis, or Refuse Derived Fuel (RDF) technologies to process the waste. The city expects the facility would be able to reduce Jakarta's solid waste by 80 to 90 percent of its current level. 

Bantargebang now receives 7,702 tons of garbage from Jakarta per day, but only able to process a fraction of the waste, Riza said. Households waste accounted for 85.3 percent of the trash, followed by markets (7.7 percent), self-contained area (3.4 percent), and water bodies (3.6 percent).

The administration estimated the 110.3-hectare garbage landfill would be overrun by next year, without any efforts to increase processing capacity or reducing the garbage intake.

Jakarta provincial government and Agency for the Assessment and Application of Technology (BPPT) inaugurated the operation of a waste-to-energy power plant in Bantargebang in MArch 2019. The plant can process 100 tons of garbage per day to generate electricity up to 700 kilowatts per hour.

The government aimed to use the project to showcase the construction of similar facilities across Indonesia. 

"We want to continue the cooperation between BPPT and the provincial government, which has been running for several years," Riza said.
