Lexmark Return Program Cartridges are sold at a discount versus the prices of regular laser printer cartridges in exchange for the customer's agreement to use the cartridge only once and return it only to Lexmark for remanufacturing or recycling.\n\nRegular cartridges without this license/agreement sold at regular prices are also available. Regular cartridges are also recyclable at no cost through Lexmark Cartridge Collection Program. Lexmark Return Program Cartridges are always made with all new parts.\n\nLexmark Return Program Cartridges & Our Environment\n\nLexmark recycles Return Program Cartridges, keeping them out of the waste stream. In 2002, Lexmark's remanufacturing efforts kept close to one million laser cartridges out of landfills. Return Program Cartridges are a great choice for the environment. Other recycling and remanufacturing options are available with regular cartridges.
