Food, green waste processing plant to be built in Wahiawa
A processing plant for “invessel conversion” will be built early next year in Wahiawa to convert green waste, food waste and sewage sludge into a marketable soil amendment.
Hawaiian Earth Recycling LLC has won a city contract for the project, which will be located on 112 acres of vacant land along Wilikina Drive.
According to city Environmental Services Department spokesman Markus Owens, HER will finance, design, engineer, construct, test, operate and maintain the facility for 10 years, and the city will pay it $118 per ton to cover the project costs.
The city made a conditional award in mid July for the project, which is expected to eventually keep 100,000 tons of waste per year out of the Waimanalo Gulch landfill. Building the plant will take about two years.
