Tour de Trash 2016

28The City’s extremely popular Tour de Trash tour series is back for an 18th year!  Tour de Trash gives participants an up-close and personal look at some of the City’s dynamic recycling and solid waste management programs.  Back on this year’s schedule is the Green Business Recycling tour, which showcases the Reduce, Reuse and Recycling efforts of some of Oahu’s most environmentally conscious businesses.

Tour 1: Recyclers and Waste Processors

Date: Tuesday, April 19

Time: 8:30 – 1:00

Start-Finish: Kapolei Hale

The Recyclers and Waste Processors Tour visits the City’s HPOWER waste-to-energy facility, where all of Oahu’s trash is incinerated to generate electricity.  HPOWER’s capable of processing up to one million tons of trash per year and providing Oahu with up to 10% of its electricity needs; that’s enough electricity to power 60,000 homes.  The tour also stops at the 100+ acre Hawaiian Earth Recycling (HER) facility in Wahiawa, where the City’s green waste is recycled into mulch and compost.  Hear about the science behind the compost process; see the long open-air windrows of compost and get a peek at HER’s new advanced irrigation system in action.  At RRR Recycling Services participants will be able to walk the elevated sort line to see how nearly 25,000 tons of recyclables from the City’s curbside blue cart program are sorted into individual material types and processed for recycling.  And at the Waimanalo Gulch Sanitary Landfill tour goers will get to see and learn about the environmental protections employed by today’s modern landfill, including its complex liner, leachate catchment and methane recovery systems.

Tour 2: Wastewater Management

Date: Wednesday, June 29

Time: 8:30 – 12:30

Start-Finish: Kapolei Hale

On the Wastewater Management Tour you’ll find out what happens to the water you wash down the drain and flush down the toilet.  The tour visits the Honouliuli Wastewater Treatment Plant, where 25 million gallons of sewage per day are treated through screens, filters, and clarifiers which clean and separate liquids from solids.  The tour then travels to the Honouliuli Water Reclamation Facility, where the Board of Water Supply further processes the wastewater into cleaner water, which can be used for irrigation.  Collection System Maintenance will also provide a cool demonstration of how sewer pipes are serviced and maintained using a robotic Closed-Circuit TV camera and a Vactor truck.

Tour 3: Recyclers and Waste Processors

Date: Saturday, September 17

Time: 8:30 – 1:00

Start-Finish: Kapolei Hale

Sewage Sludge Now Going to H-POWER

This first-of-its-kind receiving station injects sewage sludge directly into H-POWER’s mass burn unit, where it is diffused into the refuse for incineration.  In the City’s continued effort to divert everything possible from landfill disposal, this new processing system at H-POWER enables the City to redirect more than 40,000 tons per year from the landfill; 20,000 tons of sewage sludge along with 20,000 tons of bulky waste that had to be combined with sludge to settle it properly in the landfill.

The 40,000 tons of additional sewage sludge and bulky wastes will be converted to energy equivalent to 22,000 barrels of oil, generating enough electricity to power 6,500 homes.  So much better than dumping it in a landfill!
