With its waste-to-energy facilities in Oahu, HPower is one of many such operations across the United States and the world that use modern environmentally sound technology to convert ordinary trash into clean renewable energy.

The facility is capable of processing 2,160 tons-per-day of municipal solid waste into refuse derived fuel (RDF) for combustion, while generating up to 57 megawatts of energy from this renewable source.

That's enough to support more than 45,000 homes.

At HPower, non-hazardous municipal and commercial solid waste is combusted in water-cooled furnaces at temperatures greater than 1,800 degrees Fahrenheit. The process reduces the waste to an inert ash that is only about 10 percent of its original volume.

HPower also features a system that recovers ferrous and non-ferrous metals from the waste stream for use by local metal dealers. This is an additional benefit that increases recycling levels in our partner communities.

HPower is equipped with modern air pollution control technology and monitoring devices, which maintain strict state and federal emission standards and have consistently demonstrated outstanding performance in all its environmental testing.

Since it’s inception in 1987, HPower ash has never failed the required Environmental Protection Agency test to determine its non-hazardous content. HPower ash is safe and regulated by the State Department of Health as a non-hazardous waste consistent with management practices for municipal solid waste ash elsewhere in the United States.

• By combusting Oahu’s non-hazardous municipal solid waste, HPower conserves scarce landfill space while reducing imported oil used to make electricity.
• Over the past 12 years HPower processed more than 2,000 tons of municipal solid waste each day – enough waste to fill Aloha Stadium more than seven times – reliably, cleanly and effectively.
• HPower reduces our dependence on imported oil – having saved Oahu the equivalent of 10 million barrels of imported oil. By providing up to 7% of the electricity used on Oahu HPower helps Hawaii achieve its goal of becoming more energy self-sufficient by reducing its dependence on imported fossil fuels.
• HPower is a proven technology – reliably, cleanly and effectively reducing by 90% the volume of waste that would have gone to the landfill - saving Oahu the equivalent of two landfills the size of Waimanalo Gulch Landfill. Thanks to HPower, we have avoided filling several hundred acres of landfill space.
• HPower recovers 20,000 tons for ferrous and non-ferrous metal for recycling each year, enough metal to manufacture 18,000 automobiles and 3.5 million aluminum cans.
• HPower minimizes impacts on air quality by closely monitoring the air emissions on a real-time basis and adhering to strict state and federal requirements.
• Each year, HPower spends more than $6.5 million on equipment and services from local vendors in Hawaii, further boosting our local economy.

HPower is proudly involved in local organizations including the Kapolei Rotary Club. HPower also sponsors the Kapolei Family Fun Run to benefit literacy programs and the Waianae Comprehensive Health Care Fun Run.

Each year, HPower participates in the Hawaii Food Bank’s food drive, collecting an average of 2,000 pounds of food annually.

Given HPower’s technical nature, it’s no surprise that HPower is a proud sponsor of a statewide science fair and school career days. HPower also contributes to the travel expenses of science fair winners enabling them to compete at the district and national levels.

HPower provides the popular “Science Screen” programs for the Leeward School District. These videos, brochures and teacher guides are aimed at middle and high school levels, providing teachers with modern science education curriculum for use in the classroom. HPower will be making an exciting announcement for further support to this program.

HPower adopted Kapolei Elementary School, supporting school initiatives throughout the year. As one part of that commitment, HPower donates the “Earth Preservers” curriculum to the 5th grade classes in an effort to make learning about protecting our environment enjoyable.

As a sponsor of “Project Graduation,” HPower supports Leeward High School graduating seniors and their alcohol-free graduation parties.
