Substitute raw materials and innovative resource technologies

Urban Mining - Resource substitution


Scientists examine
whether and how raw materials can be replaced in production processes by resource substitution. During the manufacture of many products, now there exists the possibility of using less resources or to replace them entirely in the ideal case. The alternative raw materials must ensure the same properties as the raw materials originally used.  Innovative technologies are being developed and tested to, for example, save rare earths in the production of components. Smartphones, laptops and batteries can only perform at current levels through the use of relatively rare metals. New approaches in production and optimized manufacturing processes reduce the use of this scarce resource or ideally even completely avoid them. Furthermore, accumulating recyclable materials are collected and recycled in the production process. Resource substitution makes it possible to avoid the looming shortage of these materials for key technologies.

> The best way to conserve scarce resources and to counter a looming shortage of raw material, is in the careful and sustainable use of the resources of this world.
