Remanufacturing is a central measure for increasing resource efficiency. The material and energy expenditure for the manufacture of a product and the associated costs are lowered. Through remanufacturing the original high level of value added is retained and the dependence on import of critical raw materials is reduced. Remanufacturing as a key component of a circular economy is viewed as being the preferred option for closing material loops, particularly compared with recycling, and possesses a high resource efficiency potential.
