Most residential and general commercial trash is disposed of at H-POWER.
H-POWER began operation in 1990 and today converts approximately 2,000 tons of waste per day into enough electricity to power 60,000 homes. H-POWER produces up to 10% of O‘ahu’s electricity and reduces the volume of refuse going to landfill by 90%. On O‘ahu, waste-to-energy works in partnership with recycling efforts to significantly reduce the amount of waste going to landfills. In addition to reducing the volume of waste entering the plant by 90% through incineration, H-POWER is actively engaged in recycling. Virtually 100% of the ferrous and nonferrous metal is recovered for recycling. The facility’s pre-processing system uses magnets to pull metals from the waste stream and eddy current separators extract non-ferrous metals from the ash, diverting approximately 20,000 tons of ferrous metals (tin cans) and 2,500 tons of non-ferrous metals (aluminum, copper, gold, silver and other precious metals) to recycling annually. Moreover, H-POWER reduces our dependence on imported oil. One ton of trash produces saleable energy equivalent to one barrel of oil. One ton of trash processed by H-POWER also reduces one ton of greenhouses gases compared to landfilling the same ton of trash.
In May 2015, H-POWER opened a first-of-its-kind sewage sludge receiving station that injects sewage sludge directly into the facility’s mass burn unit where it is diffused into the refuse for incineration. This enables the city to redirect more than 40,000 tons per year from the landfill; 20,000 tons of sewage sludge along with 20,000 tons of bulky waste which had to be combined with sludge to settle it properly in the landfill. The 40,000 tons of additional bulky wastes and sewage sludge will be converted into the energy equivalent of 20,000 barrels of oil, generating enough electricity to power 1,500 homes.
