There is still time to reserve a seat for the Tour de Trash: Recycling and Demolition Recycling on Thursday, August 22nd. As construction of roads, rail, housing, and buildings continue on Oahu, learn how some companies are transforming this material into new, usable forms. Tour and transportation are completely free. Call 768-3200 now to sign up.


Visit West Oahu Aggregate to see how they separate and recycle demolition material for a variety of different purposes. Dirt is recycled into quality topsoil, rocks are crushed into various sizes for wall building and ground cover, and concrete and asphalt are used for aggregate in their recycled, ready-mix concrete.


PVT Land Company operates Oahu’s only construction and demolition landfill. Up to 80% of the total debris processed at PVT is recycled or processed into feed stock.  Learn how the feed stock is converted into synthetic natural gas through their gasification process.  The natural gas that is generated creates enough energy to power about 12,000 homes. Other material like metals are recycled overseas and rock and concrete are mixed as aggregate into road pavement.


Island Demo offers building deconstruction services to salvage as much as possible from demolition projects for reuse and recycling. Take a tour around their inner-city transfer station, which serves as a convenient option for contractors who can be spared the delivery to the PVT themselves.


There is one more Tour de Trash event scheduled for 2019. We are currently adding to a waitlist for our Tour de Trash: Recyclers and Waste Processors on Saturday, September 21st.  Call 768-3200 to sign up.

Tire Recycling

What happens to your old tires when you exchange them for new tires at a retailer or wholesaler?  What do you do with tires that you no longer need and want to get rid of?  These are valid questions for anyone who owns a vehicle.  The City provides the answers and services to dispose, or for some tires, recycle.

New tire purchases require the retailer or wholesaler by law to accept and recycle your old used tires.  They are also required to charge a fee to dispose of tires even if the buyer chooses to keep their tires.  This fee is used to pay for the cost to contract a tire recycling business to pick up the tires and prepare them to be shipped to the mainland to be transformed into recyclable products.

Homeowners who may have collected a few tires are able to dispose of their tires at City disposal facilities.  The City provides six public refuse convenience centers and two transfer stations on Oahu.  Residents are able to take up to four (4) passenger tires per month.  Heavy truck or equipment tires will not be accepted.  Tires collected at City sites are disposed of at H-Power and are used as an excellent fuel source to generate electricity for our island homes.  For more information, please visit our website at or call us at 768-3200 and press option 7 for assistance.

The always FREE Tour de Trash allows participants a behind the scenes look at how trash, wastewater and recycling is handled on Oahu.  The goal is to raise public awareness to help facilitate better public discussions and decision-making on recycling and waste management initiatives.

Tour 1: Recyclers & Waste Processors

Date: Tuesday, April 16th, 2019

Time: 8:30am-1:00pm

Start/Finish: Kapolei Hale

The recyclers and waste processors tour follows the path of our opala from the blue, green, and gray carts to their respective sorting, composting, and waste-to-energy facilities. This tour is a great introduction to the City’s main solid waste programs and starts off with a visit to the City’s H-POWER waste-to-energy facility, where all of Oahu’s trash is incinerated to generate electricity. H-POWER is capable of processing up to one million tons of trash per year; providing Oahu with up to 10% of its electricity needs – 70 megawatts of power, or enough electricity to power 60,000 homes. The tour also stops at RRR Recycling Services where all of the City’s curbside blue cart material is received and processed. Tour goers will follow the recycling stream through the elevated sort line and see how paper, plastic, metal, and glass are separated and prepared for shipping to overseas end users. At Hawaiian Earth Recycling (HER) participants will see how yard waste from the curbside green bins is recycled into mulch and compost. HER staff will explain the science behind the composting process; from mulching and open air windrow management to screening and mixing their final product. At Waimanalo Gulch Sanitary Landfill tour goers will learn about the environmental protections employed by today’s modern landfill including its complex liner, leachate catchment, and methane recovery systems.

Tour 4: Reuse Tour (Brand new tour in 2019!)

Date: Tuesday, July 23rd, 2019

Time: 8:45am-12:45pm

Start/Finish: Kapolei Hale

This brand new tour will feature organizations that are doing their part to reduce our waste at the source. Part of their work includes salvaging or accepting donations of construction material, tools, appliances, furniture and other home goods to be refurbished, resold and reused. Re-Use Hawaii is a nonprofit organization established in 2006 whose mission is to reduce waste through alternatives to demolition from public donations of building materials. They redistribute these materials to the community as an affordable resource. They also work to deconstruct instead of demolish buildings in order to salvage the reusable material. The Salvation Army is an international organization that came to Hawaii in the 1890s. Their mission is to aid in providing for the material, emotional and spiritual needs for those requiring assistance. At their headquarters, we will see how they provide housing and work for those in need, receive truckloads of donations from around the island, sort, refurbish, distribute to their other thrift stores and resell the items to help support their cause. Honolulu Habitat for Humanity is part of a global, nonprofit organization that seeks to eliminate substandard housing through constructing, rehabilitating and preserving homes. Their ReStore section is a home improvement store and donation center that sells new and gently used furniture, appliances, building materials and home accessories to the public at a fraction of the retail price. Proceeds raised at ReStore go towards supporting their mission of providing housing for those in need.
