It means that 40% of the raw material used to produce our cookware comes from iron reprocessed from manufacturing waste and pieces with small imperfections. This reprocessed material is melted and properly mixed with the new raw material. Additionally, a very small amount of reprocessed iron is collected from outside our factory and goes through a rigorous selection process. The quality of our recycled iron is crucial to a world-class final product.
In fact, quality control is the reason we don't use 100% recycled iron. Our 40% blend ensures the highest possible grade. Using 100% recycled iron would impact the quality, resulting in a softer piece.
