SUSTAINABLE WASTE MANAGEMENT

As an island city, waste management for Honolulu is more
complex than for comparable communities on the continent. The
City administration has endorsed the statewide Aloha+ Challenge
waste reduction goal of 70% by 2030, and we continue to reduce
the amount of waste going to our only landfill. We are committed
to tracking the amount of waste we generate on O‘ahu, increase
the amount diverted away from our landfill (currently approaching
90% capacity), and develop strategies for source reduction.

Understanding the close nexus between waste and climate
change, we will track and report on the percentage of plastic in the
waste stream. Both the decomposition and incineration of plastic
material releases greenhouse gas pollution into the atmosphere.

In 2018, to determine the most effective strategies for managing
solid waste, key City departments, including the Resilience Office,
and nonprofit stakeholders partnered to help update the City’s
Integrated Solid Waste Management Plan (ISWMP), to guide new
waste goals for the City over the next ten years.
