By centralizing production volume in TechCenters

We process our spectacles at our dedicated TechCenters where we cut, edge and fit the lenses. By moving these processes from stores to industrialized facilities, GrandVision is able to better control its environmental footprint by driving efficiency gains in areas of energy use, transportation, water and waste management. The expected results from centralizing these activities include:


  • Increased efficiency in electricity and water usage due to more sophisticated equipment in the TechCenters
  • Higher precision and a reduction in material scrap, and therefore a reduction in waste volumes and environmental impact
  • Increased activity control executed by dedicated staff
  • A significant reduction in occupied space, leading to savings in supply and management resources


Currently, we have a network of 17 state-of-the-art TechCenters for industrial processes. In 2018, the percentage of spectacles processed in TechCenters as part of total spectacles sold increased from 67% to 70%. This increase was in line with the growth of our retail network, our centralization planning and our 2025 target to have at least 85% of our spectacles processed at our TechCenters.


Environmental pressure of our TechCenters


With the centralization of our cut, edge and fit facilities to GrandVision TechCenters, we are continuously reducing the environmental footprint of our production activities through efficiency gains in the areas of energy, water and waste management. The table below provides insights into the environmental metrics for our TechCenters, measured per spectacle processed. Compared to 2017, we have reduced the environmental pressure of our production processes.


  Total energy consumption (GJ) Total CO2 emissions (Ktons) Total water consumption (1,000m2) Off cuts offered for recycling (tons)* Energy efficiency (MJ per spectacle processed) CO2 efficiency (grams per spectacle processed)** Water efficiency (liters per spectacle processed)
2015 41,169 3.49 20.0 438 4.6 391 2.24
2016 43,728 2.98 23.2 596 4.2 284 2.21
2017 42,393 2.97 22.8 534 4.0 282 2.16
2018 45,151 2.68 22.91 516 3.9 231 1.98
2025 target - - - - - 205 1.87

*The scope of TechCenters of 2017 has been updated and excludes our TC in Switzerland, as this was only acquired in December 2017 - it is included in the 2018 data.


In 2018, we started increasing our insights into the waste management practices of our TechCentres. We are tracking different waste streams, including plastic packaging waste, paper and cardboard, residual waste that comes from cutting and edging lenses and scrapped stock (unused products). We aim for more efficient processes and as little waste as possible. In 2018, the waste we offered for recycling purposes increased from over 700 to 844 tons.
