Altair Chimica is one of the leading players in producing potassium inorganic derivatives and is part of the Esseco Group, the industrial group that has been developing products for almost a century to ensure high performance and safety in the field of inorganic chemistry and oenology. In 2005 Altair has been the first European KOH producer to fully convert to mercury-free membrane cell technology. The new mercury-free chlor-potash plant, build on green field to avoid any potential mercury contamination, was the first one in Europe and, from a technological point of view, among the most advanced in the world for the production of very pure potassium derivatives. Altair Chimica works everyday to foster a useful and sustainable innovation of processes, technologies and products, in close collaboration with universities (Firenze, Pisa) and the CNR (National Research Council, the largest public research institution in Italy).
