Honolulu picks Hawaii Gas to supply it with renewable natural gas from wastewater treatment plant

By Duane Shimogawa, Pacific Business News.

Honolulu has chosen Hawaii Gas to supply the city with biogas from its Honouliuli Wastewater Treatment Plant in Ewa Beach in West Oahu.

A contract awarded to Hawaii Gas last week expires on Dec. 31, 2024, with options to extend. The city sent out a request for proposals for the sale of biogas from the plant in July 2015. The value of the contract was not immediately known.

The biogas at Honouliuli is currently burned and not utilized. Biogas is produced at wastewater treatment plants and landfills when biodegradable waste is broken down through chemical reactions and by microbes.
