Bob Cappadona manages the fifth-largest recycling facility in the United States: Casella Waste’s materials recovery facility in Charlestown, Massachusetts. That’s where more than 30 area municipalities bring their curbside recycling for processing.
Cappadonna says the biggest issue he has to deal at his facility is what he calls “plastic bag contamination. Single-use plastic grocery bags can clog the automatic sorting machines used to make recycling financially feasible. The bags are such a problem that sometimes Cappadonna has to shut down his 700-ton a day process so employees wielding knives can climb in to the huge machines to cut errant bags out—a delay that can take hours.
