The administration in Balikpapan, East Kalimantan, is touting its waste management facility as being the best on the island, and perhaps even in Indonesia.
"We can make this facility a success because of the synergy between the city administration and the community," Ali Munsjir Halim, head of the municipal sanitation office, told The Jakarta Post recently.
"Cleaning up the environment starts at the most basic level, households, then neighborhood groups, villages, subdistricts and districts."
The facility, TPA Manggar, was built in 2000 but only began operating in 2002. It utilizes a landfill system.
Spread out over 25.1 hectares of land, it is divided into separate zones. The first zone, some 2.6 hectares, is expected to be completely full after nine years of operation. The second zone, measuring 3.3 hectares, is now being prepared.
The facility currently processes between 280 and 300 tons of waste daily, Ali said.
He said the waste management process began with households disposing of their garbage in containers provided by the municipality for every neighborhood group.
The garbage is then transported by truck to temporary landfills before being taken to TPA Manggar.
Once there, some 100 garbage pickers separate organic from inorganic waste.
The organic waste is then layered into the ground by excavators between alternating layers of soil. Methane traps are planted in the layers to make the process environmentally friendly, Ali said.
"These layers turn into a rich compost," he added.
He said an Australian company had recently signed a memorandum of understanding with the city administration to buy the compost after five years of processing.
Geo-membrane layers are also implanted to prevent alkalis formed during the decomposition process from entering the groundwater. They are instead channeled away in pipes to processing pools.
The facility boasts three alkali-processing pools made of concrete, each with a control well whose water is tested every three months for heavy metal content. Another pool will be built later this year to filter heavy metals.
"To date, all our water quality checks have met with required quality standards," Ali said.
The city administration has allocated Rp 4 billion (US$440,000) in its 2008 budget for the maintenance, running costs and development of the facility.
Ali said toxic and dangerous waste was managed at a separate site by a private company.
Visitors to TPA Manggar are often caught off guard by the scenic surroundings and rustic wooden bridges over the neatly arranged alkali-processing pools.
Vegetables are grown on open fields next to the pools, and there is a conspicuous absence of bad odors.
"It feels more like a recreation area than a landfill site," one visitor remarked.
"I have visited several waste management facilities across Indonesia, and this is the best I have seen so far," Harry Suryadi of Knight Journalism International said. [The Jakarta Post]
