Singapore's Bottom Ash Tested for Use in Construction

If testing is successful bottom ash from Singapor's waste to energy facilities could be turned into building materials for the country's booming construction industry 23 November 2011 IBA Green testing Incinerator waste from Singapore For Treatment and Conversion to Safe Building Materials IBA Green, a wholly owned subsidiary of California based Pioneer Exploration, is testing bottom ash from a waste to energy facility in Singapore for its potential to be used as a construction material. According the company, it has developed a by-product line of building materials manufactured through a process of stabilising and treating incinerator bottom ash. IBA said that it is conducting the tests in response to a request for a proposal to convert the ash into much needed building materials for Singapore's booming construction industry. Currently Singapore's Semakau Landfill is receiving an estimated 500,000 tonnes of bottom ash each year, at a cost of over S$130 ($100) per tonne. The company expects its treatment to result in a solidified product which will yield an extractable metal content well below levels of standardised testing, and compliant with levels allowing its conversion into safe building materials. IBA said that this process could save Singapore millions of dollars in landfill costs and extend the life of the landfill. In addition, the resulting building materials will yield an additional revenue source. The company added that its conversion plants can be established on less than three acres of land - ideal for urban areas such as Singapore.
