Holland recycles slag into insulation

The video discusses how Holland has developed a new industry by utilizing industrial waste, specifically glass furnace slag, which was previously discarded as worthless. The process involves mining slag heaps for raw materials, mixing them with other minerals, and reprocessing them in a furnace. The slag is then transformed into fine fibers, similar to mineral wool, which is used for building insulation. This innovation turns waste into a valuable product with a ready market, demonstrating the potential of creating something valuable from nothing.
