Covanta Energy Corp. is upgrading its waste-to-energy facility in Niagara Falls, N.Y., at a cost of about $30 million.

The Morristown, N.J.-based Covanta is undertaking four infrastructure improvements to give the company the flexibility to manage and optimize waste supply, according to James Reagan, manager, corporate communications and media relations, in an e-mail.

The improvements include a special waste handling facility to prepare waste for processing; a new rail infrastructure that will enable the facility to accept waste by rail; the installation of a new steam pipeline to send steam to neighboring businesses; and a natural gas-fired boiler that produces steam to back up the facility’s waste-to-energy boilers.

The project will create more than 20 permanent jobs.

The facility processes 2,250 tons of waste per day.
