We do our utmost to ensure the safety of people and the environment since most of our operations involve aggressive substances and demanding processes. Careful management of raw material resources and compliance with the principles of responsible care are of vital significance to us. This is why we have been recycling our two largest by-products, sulfur dioxide and hydrogen chloride, since 1970; they are reused as starting materials for manufacturing sulfuric acid and hydrochloric acid respectively.
