The present-day ecological challenges compel businesses to clear standards. Here, the goal is to guide the direction of technology, economy and ecology in the same direction and in an environmentally compatible manner for the future of humanity. One very important aspect in this respect is the introduction of efficient energy and environmentally closed material cycles.
As is well-known, the extraction of aluminium requires a relatively large amount of energy. However, this ostensibly inefficient energy use, is very rapidly compensated by processing, usage, and, finally, in recycling. Thus, Küffner aluminium frames and skirting profiles can even be used after decades, without any loss and repeatedly recycled.
