Service features
We regenerate used etchants and sell it as new etchants.
Used etchants discharged at printed writing board manufacturers are recycled into ferric chloride solution and sold to printed writing board manufacturers. This regeneration of used etchants produces multiple by-products in its process. We sell ferric chloride solution, which exceeds the required amount to be reused as new etchants, as a flocculant for wastewater treatment of sewage and various factories, and for the treatment of livestock feces and urine. Ferrous chloride solution is sold as a reducing agent for wastewater containing chromium. We also recover cooper contained in used ferric chloride solution and sell it to steel manufacturers as copper pellets and copper powder.
