More resources to rise from ashes
Instead of ending up in the Semakau Landfill, more metals found in the incinerator ash will be recovered and given a new lease on life from the second half of next year. That is when a metal recovery facility for incinerator bottom ash (IBA) ? or ash collected in pits at incineration plants ? could be up and running in Tuas, according to the National Environment Agency (NEA).
The agency recently called a t6ender to develop and operate the facility which will recover ferrous metals ? those with iron content and magnetic properties ? and non-ferrous metals, such as aluminum and copper, from bottom ash generated at the four incineration plants here. Over 1,500 tonnes of bottom ash are generated a day, and the NEA projects that the figure could rise to about 2,100 tonnes by 2023. Metals make up about 8 to 15 percent of the bottom ash by weight.
The facility is part of the government’s plan to put incinerated ash to greater use and prolong the lifespan of the Semakau Landfill beyond 2045. It is developing environmental standards and application guidelines for ash reuse over the next few years but is, in the meantime, “looking at initiatives to recover metal from IBA as part of resource recovery”, the NEA stated in its tender.
