Bali will be the first province in the country to produce electricity using organic garbage, with zero waste.

PT Navigat Organic Energy Indonesia, an British-based power company is developing an installation in Suwung final waste site in Denpasar, using 10 hectares of land granted by the provincial administration.

"We are developing a waste-driven power plant that we call Integrated Waste Management (IPST) Sarbagita, an acronym for Denpasar, Badung, Gianyar and Tabanan," Navigat Organic Energy president director Soeyoto told The Jakarta Post on Tuesday.

Those four regencies have agreed to provide all necessary facilities, including garbage supply, he said.

"We will need 800 tons of garbage a day, from four regencies (Denpasar, Badung, Gianyar and Tabanan) to be used as raw-material for the power plant," Soeyoto said.

The plant, with a total investment of 20 million Euros (more than US$31 million), would use Galfad technology (gasification, landfill gas and anaerobic digestion) from the United Kingdom to create electricity.

"After we receive waste from the four regencies, we will separate the organic from inorganic waste," he said.

The wet organic waste, he said, would be crushed, dried and later be transformed into compost and would undergo a process called anaerobic digestion, to produce gas.

While the dry organic waste, he said, would go though pyrolyzes and gasification processes.

Gasification is the process of converting biomass into combustible gases using a thermal process. This process will produce synthetic gas which can be converted into electricity after undergoing a process in a boiler machine.

"The whole process will yield zero waste," he said, adding that the project would be conducted in phases.

"In the first phase, we will produce two megawatts of power this October," he said.

The second phase in June 2009, they would double the production into four megawatts and 9.6 megawatts in 2010, he said, adding that his company had made a deal with the state-owned PT PLN to supply electricity to Bali.

"We signed an agreement with PLN in Nusa Penida yesterday," he said.

Soeyoto said Similar technology was already being used in other countries but they had not put it together into an integrated system like the one in Bali.

Separately, PLN Bali distribution office head Sudirman said that he expected the waste-driven power project would help PLN save money.
