Samsung's S.T.A.R. Program is a free service brought to you by Samsung for our business and consumer printer customers willing to take responsibility in helping to keep the environment clean. This environmentally conscious program safely reprocesses empty cartridges into their major usable component materials (plastics and resins, metals, non-metal materials, packaging cardboard, and other miscellaneous materials) and then makes those recovered materials available to the raw materials marketplace for reuse in new manufacturing for a range of products.
