Recycling and Landfill Diversion

Recycling Data Tables
Future Plans

Below are Oahu's solid waste generation rates for calendar year 2016. Although waste to the landfills and H­-POWER is tracked monthly, recycling data is provided by recycling companies, including some businesses that recycle their own waste, that are surveyed annually. (In some cases, where exact amounts are unknown, estimates are used.) Recycling data for 2016 was gathered and compiled during the first half of 2017; updated charts and analysis are posted below. Recycling data for 2017 will be gathered and compiled during the first half of 2018 and posted by mid year.


Oahu’s waste data is presented in two charts:

  1. TOTAL WASTE, which includes Municipal Solid Waste (MSW) and Construction and Demolition (C&D) material, processed through recycling, waste-to-energy or landfilling; and
  2. MUCIPAL SOLID WASTE (MSW) includes everything but C&D material.

Both charts, which present data for the most recent five (5) calendar years (2012-2016), illustrate how Oahu’s waste has been diverted from the landfill at increasing rates through recycling and waste-to-energy.

TOTAL WASTE data is presented in the chart below. For 2016, rates for C&D material recycling and disposal continued to rise as a result of ongoing major construction projects on island.  C&D recycling, general material recycling and waste-to-energy combined to divert more than 76% of Oahu's total waste from landfills. 

Total Waste Rates 2012-2016

There are two landfills on Oahu: the City’s Waimanalo Gulch Sanitary Landfill (WGSL), which is designated for MSW, and the privately-­owned PVT Landfill, which is permitted for Construction and Demolition (C&D) waste only. 

MSW data is presented in the next chart. An increase in the waste-to-energy rate combined with strong recycling numbers helped Oahu achieve a new high MSW landfill diversion rate of over 80%.  Important to note that of the roughly 21% of material landfilled at WGSL in 2016, less than 6% was MSW, with the rest consisting of ash and non­combustible residue from H-POWER.

MSW Rates 2012-2016

For a breakdown of Oahu's waste by type and tonnage, see the 2006 Waste Characterization Study. For a further discussion of solid waste projections for 2018, see future plans.

Recycling data: The City has gathered annual recycling data since 1988 (except for 1989 and 1990). The tables below provide detail of tons recycled by material type. General material recycling on Oahu has increased by more than 500% since 1988 to over 400,000 tons today.  Recycling of construction and demolition (C&D) materials, such as concrete, rock and asphalt, accounts for an additional 800,000+ tons to the recycling rates, for a total of over 1.2M tons recycled for 2016. While C&D recycling rates tend to fluctuate based on the volume and type of construction projects undertaken from year to year and the market value of the recyclable materials, rates have risen significantly over the past few years.
