Alter Trading Corp. has purchased Wausau Scrap and Recycling Corp. (WSRC) for an undisclosed amount.

The St. Louis-based scrap metal recycling firm Alter acquired Wausau, based in Wausau, Wis., an industrial scrap recycling firm operated by the Wallach family since 1951. Peter Wallach managed the business from 1966 until his passing last year, according to a news release.

"Peter ran a great business and was a strong supporter of all local business in the Wausau area; and we look forward to continuing in his footsteps," said Bill DeWindt, regional director of operations of Alter’s northern Wisconsin business.

Said Toby Wallach, WSRC chairman and Peter’s wife of 53 years, "After working for decades to build this business and maintain good family-supporting jobs for our community, we were committed to finding a buyer that would continue our traditions of integrity and fairness by valuing the employees and providing excellent customer service. With Alter, a family-oriented group with a great reputation, we found the honest, dedicated leadership that will continue this company's success into the future."
