Clean contaminated material

A clean material can help filter precipitation before being absorbed into the ground, has been patented by civil engineering and environmental engineering researcher Naji Khoury (Temple University).

Naji Khoury used a mixture of recycled plastics bottles and earth to create a substance called plastisoil , similar to cement. When mixed with coarse aggregate such as stone, gravel and heat, this mixture produces a foam-like substance that is water-repellent and porous like plastic, can be filtered to remove or reduce pollutants. like engine oil.

When using this material to build pavements, roads, parking lots, etc., when rainwater flows through, it will filter the dirt before the water penetrates into the ground, reducing the environmental pollution. . It is estimated that about 30,000 recycled plastic bottles will produce 1 ton of plastisol foam to reduce waste to landfills. At the same time, plastisil production uses less energy than cement or asphalt, costing many times cheaper.
