Another PS product maker, Solo Cup Co. of Lake Forest, Ill., also launched a recycling initiative last month, teaming with TerraCycle Inc. of Trenton, N.J., which works with schools and nonprofits to recycle snack-food packaging. Solo will make a 2-cent donation to schools, nonprofit groups or Keep America Beautiful for each trademarked Solo Squared PS drinking cup that is collected and sent, at Solo’s cost, to TerraCycle, which turns the recycled material into benches, playground equipment and other outdoor products.
