The foul smell of piling garbage at the largest landfill in Bali, the Suwung landfill, has been a source of disgust for the Balinese.
Thanks to technology, however, people on the island-province can now look forward to making use of their waste.
Home to household waste from four areas of Bali - Denpasar, Badung, Gianyar and Tabanan - the landfill receives as much as 800 tons of waste per day.
As two third of the waste is organic, it releases methane gas -- the source of the "foul smell" and is one of the greenhouse gasses that contributes to global warming - to the atmosphere.
The Bali administration, working with PT Navigat Organic Energy Indonesia (NOEI), set up an integrated waste management system at Suwung by building its first biogas plant.
The plant would capture methane gasses and turn it into energy in the form of electricity. The plant will also help rehabilitate the landfill site.
"By August 2008 the facility would be able to produce two megawatts for public use," PT NOEI spokesperson Bernt Bakken said Sunday.
The facility was launched by the Bali Governor Made Dewa Beratha on Dec. 13, sporting the momentum of the United Nations Climate Change Conference that ended on Dec. 15.
It is the first project in Bali carried out under the United Nation's Clean Development Mechanism (CDM) -- a carbon trade scheme that enables a group of developed countries and countries in transition, which are binding for emission cuts to earn emission reduction credits by promoting sustainable development in developing countries.
Indonesia has 11 projects under the carbon trade scheme registered at the CDM executive board so far, with only two of them approved by the board.
The biogas plant project would reduce around 123,423 tons per year of the amount of methane gasses released to the atmosphere, cutting the greenhouse gasses that contribute to global warming.
Bakken said from 2010, the facility would produce 10 Megawatts of electricity.
State Electricity Company (PLN) has signed an agreement to buy power from the biogas plant.
PT NOEI uses a Jenbacher machine, distributed by GE Energy. GE Energy country executive Gatot Prawiro said waste-to-energy conversion was a good solution to provide energy in areas that has no access to the national power grid.
Bali is still dependent on Java for power supply, with 130 Megawatts of the 439 Megawatts needed to power Bali comes from the Paiton Power Plant in East Java.
