TRENTON, NJ — Five Walmart stores on the East Coast will be the first to test a new collection system for 28 types of trash that TerraCycle turns into new products. Brigades currently have to mail in trash they collect. The collection system at the five Walmart's, going into place Oct. 1, will allow anyone to drop off any waste that New Jersey-based TerraCycle accepts in converted 20-foot trailers at Walmart stores in Secaucus, Vineland, Deptford East and Lanoka Harbor, all in New Jersey, and Tullytown, Penn.
