A new law has strengthened a sustainable aviation fuel project in Hayward, Wisconsin, that aims to convert woody biomass — trees and forest residues — into jet fuel for commercial and military turbines.

The legislation, signed into law this month, gives the Hayward initiative a firmer policy foundation as its developers work to scale forestry-derived fuel production. The project sits at the intersection of two pressures on the US aviation sector: airline demand for lower-carbon fuel to meet net-zero commitments, and a persistent supply shortage of qualified sustainable aviation fuel that has kept prices well above conventional Jet A.

Wisconsin's northern forests supply the feedstock logic. The Hayward area, a historic timber region, has access to the low-grade wood, harvest residuals and thinnings that forest-to-fuel processes can use without competing with food production — a common criticism of crop-based biofuel pathways. Forestry stakeholders in the state have promoted such projects as a way to add value to a resource that often goes unharvested or is left to burn or decay.

For airlines, the arithmetic is straightforward. Sustainable aviation fuel accounts for a small fraction of global jet fuel consumption, and carriers from major US network operators to cargo airlines have signed offtake agreements with producers at premium prices to build supply chains ahead of regulatory mandates and voluntary carbon targets. A new domestic production node in the Upper Midwest would shorten logistics for Midwest hub operations and add volume to a market where every new facility matters.

The law's passage also signals state-level willingness to compete for advanced-biofuel investment, which has concentrated to date on the US Gulf Coast and West Coast. States that pair feedstock access with supportive statutes are better positioned to attract the capital these plants require — capital that remains the gating factor for most announced projects, whatever their technical maturity.

The project's developers now face the standard sequence for any fuel venture targeting turbine use: securing financing, completing engineering, obtaining environmental permits, and achieving qualification under ASTM standards before the first commercial gallon reaches an airport fuel farm. Certification, not announcement, determines whether a project contributes to airline decarbonization targets.

If the Hayward facility advances on schedule, Wisconsin would join the growing list of states converting forest biomass into certified jet fuel — a pathway airlines are watching closely as they weigh how to meet fuel-related emissions commitments with supply that remains scarce and expensive.
