On March 2023 a road at Penrith NSW become the first in Australia to include recycled coffee cups, the result of a project between State Asphalt Services and Closed Loop, the operator of the Simply Cups recycling program.
Closed Loop said the paper cups were a beneficial additive, and the roads had improved pavement durability and crack resistance, as well as wet weather skid resistance, a 24 per cent lower carbon footprint, and reduced noise levels.
