A Galician research team has developed a new system, pioneer in Europe, heavy metals such as iron and aluminum recycling. This is material that after collecting them are reused in the engineering industry. The coruñesa Sogafrisa company, specializing in the treatment and recycling of hazardous industrial waste, has successfully completed the testing phase of its plant, at a cost of 1.5 million euros.

To date, the metal remains buried in a security deposit where were stored indefinitely. However, a multidisciplinary group of chemists and engineers gallegos has designed a system of treatment with which they will be treated and processed 15,000 tonnes of this waste of the aluminium industry. During the process of upgrading separate components such as iron, graphite, and refractory material. They subsequently Sievers and crushed on machines which secrete metals, so extract iron and aluminium which will be integrated, again, in the industrial process. The non-metallic elements will be used to produce cement.
