Waste-to-Energy Expansion and Refurbishment Project
As a land of beauty packed with residents and tourists year-round, there simply isn't a lot of space available on the Hawaiian Island of Oahu to send municipal solid waste to landfills. A key solution to address this dilemma is an advanced waste-to-energy facility that sits on a 23-acre industrial park in Kapolei, Hawaii. For the past two decades, this facility has transformed about 2,000 tons of municipal waste a day into energy that is sold to the local power company—enough to support 45,000 homes, leaving just 10 percent of the original waste volume as residual ash. Waste is combusted in water-cooled furnaces using refuse derived waste (RDF) technology at temperatures higher than 1,800 degrees Fahrenheit. Recent upgrades to pollution control systems use fabric filters to meet or exceed all state and federal emission standards.
HDR provides owner's engineer services for an expansion of the existing facility and refurbishment of existing equipment components. The expansion will add a single train mass burn unit to increase system flexibility and ensure that the facility will continue to operate well into the future. The new unit will be equipped with state-of-the-art air pollution control equipment that should allow it to lower NOx emissions below those of similar facilities in the continental United States. HDR provides construction monitoring and startup oversight for this 900-ton-per-day expansion unit that is scheduled to be complete in 2012.
