The Plastic Lumber Company, Inc., (PLC) is a manufacturer that takes in post- consumer plastics (i. e., empty milk jugs) and recycles those plastics into a “plastic lumber” that can be used to build furniture, decking, and a variety of other items. Because Plastic Lumber has a strong focus on sustainability, the company managers try, whenever possible, to use recycled materials and to invest in sustainable projects.
