The allowance of recycled and sustainable materials in
construction will, in the long run, help airports meet sustainable
goals — but more needs to be done. The FAA is looking at a
variety of materials that could help make projects last longer, or
reduce their ongoing carbon footprints.
Such materials will not be AIP-eligible, however, until and if
they have been progressed through FAA studies and evaluation,
largely at the FAA William J. Hugh’s Technical Center in Atlantic
City, N.J. All of these actions ultimately will contribute to
improving the sustainability of airfield construction projects,
which in turn will help sustain a healthier environment.

The FAA is looking at the potential for several new
materials to be used at airports, to boost sustainability
of maintenance efforts and construction projects.
