The Jakarta
administration is planning to build three treatment centers that will use waste
to generate energy, Governor Fauzi Bowo said on Wednesday.
“What we
want is to turn waste to energy, and this process has already begun,” Fauzi
said.
The Cakung
Cilincing intermediate treatment facility in North Jakarta, which began
operating on Aug. 1., uses mechanical and biological technology to recycle
inorganic waste and to ferment organic waste to produce gas that can be used as
fuel. After processing, the waste is then sent to a landfill.
The
treatment center will be able to process 400 tons of waste daily until the end
of the year and 600 tons daily from January. It will reach its full capacity of
1,300 tons in July next year, he said.
When
running at full capacity, the Cakung Cilincing ITF will be able to produce 4.95
megawatts of electricity, or 445,669 million metric British thermal units of
gas fuel.
Fauzi said
that the two other intermediate treatment facilities, would be built in Sunter
and Marunda, both in North Jakarta, before the end of the year.
The
existing Sunter waste facility, which sits on five hectares of land, will be
upgraded into an ITF, Fauzi said.
“We are
going to enhance the technology at the Sunter processing station into an ITF,”
Fauzi said. “The city sanitation office will cooperate with private sector
companies interested in investing.”
The Sunter
ITF, Fauzi said, would use technology based on an incinerator that would be
capable of reducing the volume of waste by 90 percent, producing a large amount
of electricity and significantly reducing greenhouse gas emissions.
Eko
Bharuna, head of the Jakarta Sanitation Office, said the Sunter project would
be tendered in September.
“We are
involving the private sector under a build, own, operate and transfer
arrangement,” Eko said. “We have chosen this option so as not to burden the
regional budget.”
“Besides
building the various intermediate waste processing facilities that are capable
of handling large amounts of waste, the city administration will also develop
reuse, reduce, and recycle centers [Sentra 3R] in Jakarta’s five
municipalities,” Fauzi said.
“In the
future, all regional developers will have to build their own waste processing
facilities,” he added.
He said
that several developers, including Pantai Indah Kapuk, had already agreed to
build 3R centers in their estates. Pantai Kapuk Indah’s 3R center would use
integrated dry anaerobic digestion and composting technology and would be built
in cooperation with a private investor and the Tsu Chi Buddhist Foundation, he
said.
“The waste
at PIK will be processed into electricity and compost,” Fauzi said. “The main
difference with the ITF is that the 3R center will have a much smaller
capacity, of around 250 tons.”
Another 3R
center planned for Pesanggrahan, South Jakarta, will be built with the
assistance of the Public Works Office’s environmental sanitation unit, he said.
Fauzi added
that the city administration would not go ahead with a plan to build an
integrated waste processing plant in Ciangir, in Legok district, Tangerang. The
decision came after Tangerang authorities zoned the Ciangir area for
residential purposes.
The city
had purchased an area of 96 hectares in Ciangir and an environmental impact
study was conducted in 1999.
Fauzi said
that while the Tangerang administration had proposed a land swap, suggesting an
area in Jatiwangi, closer to Jakarta, the city authorities preferred to develop
the Ciangir land into residential estate in line with the new zoning
requirements.
With the
Ciangir ITF center scrapped, he said, the city would now have to rely on the
three planned ITFs.
“With these
three ITFs and the Bantar Gebang landfill, Jakarta’s waste problem will be
solved for the next decade, as their cumulative processing capacity will be
more than 8,000 tons per day,” he said.
