Trash Tips for a Green Holiday Season


More refuse is produced during the holiday season than any other time of the year.  Presents leave us with mountains of boxes and wrapping paper, while holiday parties can generate enormous amounts of cans, bottles and jars; not to mention all of those Christmas trees.  Holiday Trash Tips and information on holiday collection schedules are posted online at

Honolulu Wins City Livability and Gold Excellence Awards

The City & County of Honolulu was honored with two prestigious awards this summer in recognition of H-POWER’s commitment to sustainable solid waste disposal.  Honolulu received the 2016 City Livability Award from the U.S. Conference of Mayors and, for the second time in three years, Honolulu’s waste-to-energy facility, H-POWER, won the Solid Waste Association of North America (SWANA) Gold Excellence Award in the waste-to-energy category.  Honolulu’s H-POWER facility successfully combines refuse-derived fuel and mass burn technologies – an achievement that has put it at the forefront of waste-to-energy innovation.


In a statement, Honolulu Mayor Kirk Caldwell commended H-POWER’s commitment to meeting Oahu’s waste management and energy needs.  “With the addition of a third boiler and a sludge intake facility at our nation-leading waste-to-energy plant, we are now diverting nearly 80 percent of our municipal waste stream from Oahu’s only landfill, and making great strides toward Hawaii’s ambitious goal of 100 percent renewable energy by 2045.”

The U.S. Conference of Mayors’ City Livability Awards Program recognizes mayoral leadership in developing and implementing programs that improve the quality of life in America’s cities.  Click here to view the City Livability Award Video.

The (SWANA) Waste-to-Energy Gold Award recognizes excellence in the design, management and operations of projects that produce renewable energy from solid waste, whether through direct combustion or through other methods.  Click here to view the 2016 Excellence Award Entry.

Nothing Wasted, Nothing to Landfill.

2015 Waste Data Sorts It Out for Recycling and Energy

Analysis of Oahu’s 2015 waste processing data has been completed, including all waste recycled, incinerated and landfilled. In 2015 the City and County of Honolulu (City) successfully diverted more than 78% of its Municipal Solid Waste (MSW) from the landfill through recycling and waste-to-energy, a stat that puts it among the nation’s leading municipalities in landfill diversion.   When waste from construction and demolition (C&D) projects is included in this calculation, the landfill diversion rate is about 75%.

Almost 37% of MSW was diverted from the landfill through recycling and nearly 42% was diverted through waste-to-energy.  Of the remaining 22% of material that was disposed of at the landfill, about 5% was MSW, with the other 17% consisting of ash and noncombustible residue from H-POWER waste-to-energy.

Through increases in recycling and waste-to-energy, the City anticipates further reductions in the amount of material going to the landfill in the coming years.  A new sewage sludge receiving station at H-POWER began operation in May, 2015 that diverts an additional 20,000 tons of sludge and 20,000 tons of bulky items from the landfill annually.  All medical waste, except for the sharps, is now processed at H-POWER.  The City is also working to redirect other wastes from the landfill to H-POWER, including Auto Shredder Residue (ASR) (about 25,000 tons) and other special wastes.  Within five years, the City hopes to have plans for reutilizing H-POWER ash as well.

Curbside Recycling Hits Recovery Milestone

In a completely fitting Earth Month coincidence, as of April 2016 the City’s curbside “blue cart” program has recycled 150,000 tons of cardboard, newspaper, plastic, glass and metal containers since its inception in 2009.  That’s the weight of 667 Statues of Liberty, or about 74 space shuttles!!

Blue carts 020The City’s curbside recycling program began in October 2007 with a pilot program in Mililani and Hawaii Kai.  Following the pilot, islandwide expansion to 160,000 single family homes began in 2009 and was completed in 2010.  Since 2009, the curbside recycling program has seen steady 2-4 percent annual increases in recovery.  For the current fiscal year, the program is projected to recover close to 24,000 tons of material – an increase of more than 5 percent from the previous year’s tonnage.  What’s more, the curbside program has also enjoyed comparatively low contamination (non-acceptable material) rates, averaging between 10 and 11 percent since the start, which is great for a program that’s still relatively young.

The curbside recycling program has and will continue to play a pivotal role in helping the City to achieve its goal of diverting as much material from the landfill as possible.  The recyclables that the City collects in its blue cart program are a valuable resource; they are sent to facilities where they are processed into feedstock that’s used to make new products.  Using recyclable materials in the manufacturing process helps to conserve natural resources and reduce energy consumption.  Keep up the good work, Oahu!
