Energy-from-Waste Project to Expand in Honolulu

Honolulu’s HPower currently converts 854 tons of municipal waste to energy every day. Thanks to a new agreement with the city, the  operation will expand, bringing its capacity up to 900,000 tons per year.

The process combusts waste materials at temperatures of more than 1,800 degrees Fahrenheit, turning it into an ash residue that can be used in roads.

In the process, the new expansion’s output will be nearly 84 MW of electricity, which is 6% of the island’s electricity usage; it will eliminate the need for nearly one million barrels of oil a year. It is expected to be completed by late 2011 or early 2012.
