Every drop is precious
Worldwide, 2.2 billion people have no access to clean drinking water. This makes it all the more important for the Silhouette Group to use every drop of water efficiently and save water. The premium eyewear manufacturer from Austria is the only eyewear producer in Europe to be certified by the European Union's Eco Management and Audit Scheme (EMAS).
The Silhouette Group uses three service water wells to irrigate the near-natural garden areas in Linz. This saves 1.5 million liters of drinking water per year. The extracted groundwater is returned to the water table through the natural soil. In addition, the company takes the utmost care to ensure the quality of the waste water. The temperature, pH value and quantity of the waste water are constantly monitored, as are its nickel, copper and chromium content. It is discharged into the sewer via a separate production waste water line. All water-polluting substances are stored safely and permanently.
Silhouette Group uses its own water treatment plants
The family business only discharges wastewater when all legally prescribed parameters have been met. For ten to twenty percent of the wastewater, this is only the case after all pollutants have been removed from the water in the company's two water treatment plants. Once the solids have been removed and filtered, the process water can be reused several times - a sustainable process. The Silhouette Group attaches particular importance to releasing 0% microplastics into the groundwater during lens production. This is made possible by a closed, ultra-modern production cycle. Milling residues and chips are consistently recycled.
