PORT COMMISSION BUDGET AMENDMENT NO. 2
Sustainable Aviation Fuels Fund Allocation for Municipal Solid Waste Study
Statement of Intent
In 2017, the Commission, as part of the Century Agenda, set a 10-year goal of having 10% of the
fuel used at Sea-Tac Airport to be from sustainable sources found in the region. This would
eliminate approximately 70 million gallons of fossil fuel which is equivalent to 682,000 mt of
greenhouse gas (GHG) emissions.
In 2019, the Port funded WSU to identify potential feedstocks to produce Sustainable Aviation
Fuel (SAF). The WSU found Municipal Solid Waste (MSW) to be the most readily available
sustainable feed stock in the region.
King County provides waste services to 37 of the 39 cities in the county. The county is also working
on a strategy to preserve landfill capacity and has been exploring options for waste to energy. As
the King County landfill nears capacity, the County needs to decide whether to further develop
their landfill or find other uses for its waste stream. As waste, composting, and recycling
dynamics change in the Puget Sound region, understanding the potential levers and drivers for
converting MSW to liquid fuels is critically important. This project could help address the Port’s,
the County’s, and the region’s challenges. The goal is to form a partnership with King County and
other potential regional partners that would include a jointly funded study on the technical and
economic feasibility of using King County’s and other regional entities that manage MSW to
produce sustainable fuels. This funding would help generate support for creating production
facilities to serve west coast clean fuel markets.
The Executive Director responded to the Energy and Sustainability recommendation to fund this
study that funding would be allocated when the Port secured funding from our partners. King
County has set aside $250,000 for a study specifically to partner with the Port of Seattle on an
MSW study. This amendment fulfills the Port of Seattle side of that partnership.
Text of the Amendment
Allocate up to $250,000 in 2021 from the Sustainable Aviation Fuels and Air Emissions Reduction
Fund, contingent on the King County contribution, to evaluate the technical, logistical and
financial feasibility of partnering with King County and other potential regional partners on
converting regional Municipal Solid Waste to sustainable liquid fuels, including on-road,
maritime, and aviation.
