The new plant will recover up to 100% of the water used to dye textiles

Textile and apparel manufacturer Olimpias Group has opened what it claims is the first water treatment plant that can recover up to 100% of the water used to dye textiles, as part of wider efforts to make its supply chain more sustainable. 

The company, which is controlled by the Benetton family and supplies fabrics and clothing to Bennetton Group, says the new plant will be able to gradually recover up to 100% of the water used at its textile production plan in Osijek, Croatia. 

Olimpias' previous plant could only remove organic substances, and not inorganic components such as hardness, alkalinity, silica, chlorides, sulphates and heavy metals, so the water could not be reused. 

However, the new plant will allow Olimpias to recover around 70% or 1,000 m3 of water per day, compared to 10.5% previously, with significantly less water being used overall – 600 m3 per day, down from 1,600 m3 each day. 

In addition, the new purifying unit, as well as the nanofiltration and OX systems, are expected to result in energy savings, lower production costs, a 1,250 ton reduction in carbon dioxide emissions, and overall improvement in the quality of the finished product. 

“In our vision there cannot be sustainability without innovation,” says CEO Gianni Zanella. “Revolutionising the treatment of the processes water we can significantly reduce water and energy consumption resulting in an important positive impact on the environment, costs savings and improved finished product thanks to the higher quality of the reused water.”

The treatment plant is part of the Wasatex (Water Saving Process for Textile) project financed by the European Union as part of the Eco-Innovation programme.
