'Plastisoil' could mean cleaner rivers and less plastic waste

A new cement-like material that could be used to form sidewalks, bike and jogging paths, driveways and parking lots, may be able to lessen two environmental problems, namely plastic waste and polluted rainwater runoff. The substance is called Plastisoil, and it was developed by Naji Khoury, an assistant professor of civil and environmental engineering at Temple University in Philadelphia. In order to make Plastisoil, discarded polyethylene terephthalate (PET) plastic bottles are pulverized and mixed with soil, and then that mixture is blended with a coarse aggregate and heated. The result is a hard yet non-watertight substance, similar to pervious concrete or porous asphalt.
