C.I.E. Compagnia Italiana Ecologia S.r.L.

Since 1980, CIE (Compagnia Italiana Ecologia) has operated as a company specialized in the construction of washing water treatment plants for metal finishing lines:

  • steel chemical treatments;
  • painting cars and household appliances;
  • extruded painting;
  • anodic oxidation;
  • aluminum extrusion;
  • aluminum cans;
  • coil painting;
  • general lines of aluminium.

In each of them, different types of treatments are available (washing, etching, phosphating, chromating, passivation, etc.). CIE's Research and Development department has also produced many innovations and patented processes such as:

  • recycling of rinse water with ion exchange resins;
  • processes for the recovery and reuse of alkaline and acid solutions;
  • detoxification of phosphating sludge;
  • super reverse osmosis for wastewater recovery;
  • multi-stage evaporators to reduce energy consumption.

Thanks to these solid capabilities, CIE was the first company able to install (in 1989) the first Zero Liquid Discharge (ZLD) process for a major steel manufacturer. Since 1989, more than 50 ZLD systems have been installed.

The latest technology patented by CIE (PUR-ALL) allows the creation of zero discharge (ZLD) systems without the use of UF, R.O. and Evaporator with a reduction in system and management costs of over 30%.

Since 2023 CIE has acquired the CISART brand, working as a designer and builder of OX Anodic and Aluminum Painting systems in full continuity with the historic brand both in terms of spare parts assistance and new projects.
