The Sigma Group started studying the possibility of creating environmentally friendly products from aluminum dross over 10 years ago in partnership with Shanghai Jiaotong University. From 2018 onwards the Sigma Group has been conducting its own R&D and possesses the ability and technology for aluminum dross detoxification and the creation of new construction materials – synthetic stone and precast concrete. In addition the detoxified aluminum dross can also be used as mineral admixture to create high strength castable refractory materials and concrete pavement bricks.
