When in your house black crows give birth to white doves, then will you be called wise.

All operations are controlled by purpose-designed catchment and purification systems for water, fumes and dust particles coming from the grinding mill, the rotary furnaces and the refinery. They are state-of-the-art systems designed to contain waste and to not exceed emission levels. Storage of waste, of lead and paste slag and dross coming from the loading of the furnaces is all carried out on waterproofed floored areas equipped with channels to collect the harmful material so as to prevent any ground contamination. All waste water, including rainwater, is routed through a piped system which leads to a purification plant. Some of the water is recycled in the production process.
