Covanta Energy Corp. has agreed on a new contract with the city of Quincy, Mass., to use the city’s municipal solid waste (MSW) for Covanta’s waste-to-energy facility in Rochester, Mass.

Covanta SEMASS L.P., a subsidiary of the Morristown, N.J.-based Covanta, said in a news release the extension of the current contract will begin in July 2013 and run for 10 years with mutual extension options. It provides the potential for recycling service after the city’s current contract expires next year.

Quincy will continue to use the MSW transfer station in Braintree, Mass, operated by Covanta and currently being renovated.
