It may not be burning a hole in anyone’s pockets, but loose change that’s tossed in the garbage is padding the bottom line of a Chester energy company.

After realizing how many coins were going through its garbage-burning incinerators, Covanta Holding Corp. developed a system to sort them out. In a single year, Covanta now accumulates about $360,000 worth of salvaged coins, according to a Bloomberg report by Joe Ryan.

“I’ve been in this business 30 years,” Senior Vice President of Metals Management Steve Bossotti said. “When I saw the amount of coins coming out of that one plant, it was absolutely an eye-opener.”

A $70 million investment in powerful magnets back in 2011 returned $61 million last year alone through scrap metal sales.

The only catch is that the U.S. Mint last November suspended a program that paid for salvaged coins due to suspected counterfeiting. Because it can’t melt down the sooty coins or deposit them in the bank, Covanta is waiting on the government.
