Develop.
and Testing of Compounds Containing Ground Athletic Shoes
Summary:
Washington State alone disposes of ~ 5 million athletic shoes each year.
Few technologies are available to convert the rubber from those shoes
into viable products. This project demonstrated that ground shoe soles
can be cleaned and potentially used as a feedstock for compounded door
mats and new shoe soles. A major technical challenge is removal of non-magnetic
aluminum from the ground rubber manufacturers.
