A California-based company said it plans to submit a proposal to dispose of ash from the Honolulu’s waste-to-energy power plant by converting the residue into environmentally friendly construction materials.

Officials from IBA Green Inc., a subsidiary of publicly traded Pioneer Exploration, said today the company would used its patented technology to treat the toxic ash and render it inert.

“We believe that our technology and the resulting building material by-products can address several issues facing Honolulu, not the least of which is the immediate reduction of toxic incinerator bottom ash from being deposited in the landfill,“ said Angelo Scola, IBA Green chief executive officer. “That same ash once treated can then safely be converted into nonhazardous eco-friendly building materials, thereby reducing some of Honolulu’s dependency on expensive imported building materials and providing the municipality additional revenue. “

The city’s waste-to-energy plant at Campbell Industrial Park, also known as H-POWER, generates enough electrical energy to power 50,000 homes. The city is in the process of adding a third boiler and making other improvements that will boost its generating capacity to be able to serve 75,000 homes.
