Iron has been proven to be used since 4000 B.C. Iron is one of the most natural materials. On the world market, it is made of up to 50 percent scrap metal. The extraction of materials is accompanied by great environmental pollution (dust and emissions), which can, however, be minimised with the help of special pollutant control equipment to a level tolerable to the environment. We use (powder-coated) iron in our NOON lamp range.
