Remanufacturing involves reclaiming products after they’ve been used one or more life cycles. The manufacturing process is started again with the materials that are essentially free. Remanufactured can cost, on average, half of what new ones do, and the business can be terrifically profitable for companies that do it well. As a general rule 70% of the cost to build something new is in the materials and 30% of it in the labour. Caterpillar Inc., in Corinth Mississippi is one such company involved in remanufacturing.
