Cardboard boxes, stacked in teetering rows, 9 feet high and 14 feet deep, were so sprawling that the inspectors needed cellphones to keep track of each other. http://www.nytimes.com/2013/03/19/us/disposal-of-older-monitors-leaves-a-hazardous-trail.html?hp&_r=1& The layer of broken glass on the floor and the lead-laden dust in the air was so thick that the inspectors soon left over safety concerns. Flat-screen technology has made those CRT or cathode ray tube monitors and televisions obsolete, decimating the demand for the recycled tube glass used in them and creating what industry experts call a “glass tsunami” as stockpiles of the useless material accumulate across the country. Recycling agencies have contacted the Environmental Protection Agency asking for immediate help dealing with the rapidly growing stockpiles of the glass, much of which contains lead. Storing millions of the monitors in warehouses is sometimes illegal since there are federal limits on how long a company can house the tubes, which are environmentally dangerous. Each one can include up to eight pounds of lead.
