Researchers Develop New Construction Material From Coal Ash Waste

A composite material made from plastic and coal ash could replace wood in construction. Although "fly ash" has been used to make concrete for some time, researchers at North Carolina A&T University have combined wet, rough coal ash, typically found in ponds and landfills, with plastic to create a material that is uncannily similar to wood, WUNC reported....
