Greenstar Recycling has expanded its carton recycling program to six municipal markets.

The Houston-based Greenstar said that in cooperation with the Carton Council, of Vernon Hills, Ill, Greenstar’s carton recycling markets now are Akron, Ohio; Allentown, Pa.; Dallas; Des Moines, Iowa; Pittsburgh; and San Antonio. Greenstar has worked with each of the cities to add carton recycling to their recycling service offerings.

Greenstar has installed new processing equipment at several of its facilities to maximize carton recycling. The equipment can recognize cartons and separate them from other items in the stream.
