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 wastewater line. All water-polluting substances are stored safely and permanently.<\/span><\/p>\n<\/p>\n

Silhouette Group uses its own water treatment plants<\/strong><\/p>\n

The family business only discharges wastewater when all legally prescribed parameters have been met. This is only the case for ten to twenty percent of the wastewater 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.<\/span><\/p>\n
