The trial is part of a collaboration pilot between the (state electricity company) PT PLN and the ministry to conceive an Indonesian National Standard (SNI) Plan for the Pulang Pisau steam electric power plantBanjarmasin, South Kalimantan (ANTARA) - The Ministry of Public Works and Public Housing has conducted a trial to utilize coal-burning waste from a steam electric power plant, known as fly ash and bottom ash, as road foundation.
The trial was conducted by the ministry's National Road Implementation Agency office in Central Kalimantan, with ash waste supplied from the Pulang Pisau steam electric power plant in Pulang Pisau District.
"The trial is part of a collaboration pilot between the (state electricity company) PT PLN and the ministry to conceive an Indonesian National Standard (SNI) Plan for the Pulang Pisau steam electric power plant," Manager of PT PLN's Palangkaraya power plan control unit Heni Setyo Handoko stated here on Friday.

Handoko noted that the two waste mixtures tested during the trial are each 50 percent of fly ash and bottom ash, with seven percent of cement of the entire mixture and a select heap composed of 70 percent of fly ash and 30 percent of bottom ash.
If the trial, currently taking place at a location within the Pulang Pisau power plant complex, yields a positive result, then the next stage of the trial will continue on a section of a national road in Central Kalimantan, he remarked, adding that the trial result will serve as reference for the SNI formulation.

"We hope the result would yield a positive result, and (the mixture) can be used on public roads," Handoko stated.
The ministry had earlier requested an SNI approval on the utilization of ash waste for road construction to the National Standardization Agency (BSN), he noted.
Fly ash is a fine particle residue produced from burning coal that is captured by an air pollution control equipment called electrostatic precipitator, while bottom ash is the residue of coal that is extracted routinely from a power plant facility.
