Covanta Expands Waste-to-Energy Plant in Honolulu

Covanta Energy Corp. has expanded the waste-to-energy facility in Honolulu.

The Morristown, N.J.-based Covanta said in a news release the expansion added a third boiler, which increased the facility’s capacity by 900 tons of municipal solid waste (MSW) per day. The expansion brings the facility’s total daily capacity to 3,000 tons and allows Covanta to process all of the post-recycled MSW for Honolulu and Oahu Island at the unit.

The facility is owned by the city and county of Honolulu but Covanta designed, built and operates the facility.

The expansion enables the facility to produce about 90 megawatts of renewable energy, or close to 8 percent of Oahu’s power needs. 

With the completed project Covanta begins a new 20-year operating agreement with the city and county.
