Materials Processing of Mendota Heights, a big collector of electronic waste, this month agreed to a $125,000 fine by the Minnesota Pollution Control Agency (MPCA) for improperly storing 5 million pounds of crushed cathode ray tubes in 2013-14.
The glass-and-lead tubes from TVs and computers dating back to the 1960s were stored in 128 semitrailers at several sites around the Twin Cities without permission of MPCA or without a waste-contingency plan. This is the largest sanction since Minnesota changed its law in 2007 to require reuse, recycling or proper disposal of 70 million tons or so annually of consumer-and-office electronics.
Tod Eckberg, MPCA state program administrator for electronic waste, said a tipster put MPCA on to the situation and that Materials Processing cooperated and sent the material to a hazardous-materials storage facility in Illinois last year, after talks with MPCA.
"They should have contacted us if they were in a pinch, and we would have figured something out," Eckberg said. "The risk is that the trailers weren't secure and there was potential for releases and spills when nobody is keeping an eye on this.
"After we found out about this, we told [Materials Processing] that we needed to locate, inspect, document violations and move forward with enforcement. We send it to a recycler or hazardous waste landfill."
Materials Processing President David Kutoff said last week: "We've dealt with it and moved on. At no time was there a member of the public or the environment at risk. We worked with MPCA to make sure things were taken care of properly."
Kutoff said he was holding the inventory pending results of tests with a smelter operator to extract the lead from the glass through a process they hoped would make the embedded components easier and more valuable to recycle.
"We learned it was not possible," he said. "We had an inventory on hand if the process worked so we could feed it for recycling. It went from a product that could be recycled to one that had to be sent for treatment and disposal."
