Optimisation de l'impact environnemental de nos processOPTIMIZING THE ENVIRONMENTAL IMPACT OF OUR PROCESSES

Producing while controlling energy, water and raw material consumption, with lower CO2 emissions and waste, is the shared ambition of each of our sites. A key element of our competitiveness, the tangible reduction of our environmental impact was top on the cards in 2018. With clear ambitions to remain exemplary by 2022.

water consumption in 2018


In 2018, we continued the modernization of our furnaces. A latest-generation furnace was commissioned in Spain in October 2018 and is showing a reduction in gas consumption of around 10% per year. And this summer 2019, we will thoroughly modernize our American furnace. We are therefore continuing to renew our production facilities and we are ultimately committed to reducing our overall energy consumption while increasing our production capacity. We have also launched the ISO 50001 certification project (energy management reference system) at all our sites by 2020. Our largest glass plant in Mers-les-Bains is already certified.


Carbon dioxide emissions decreased by 1.96% between 2017 and 2018, a reduction of over 4,722 metric tons in the CO2 discharged into the atmosphere. The operation of our largest furnace rebuilt in our Mers-les-Bains plant in 2017 contributed significantly to this by allowing us to substitute fuel oil with much less emissive gas. Overall, our fuel consumption for the group was reduced by more than 75% per ton of glass produced between 2017 and 2018. Our 2022 objective is to reduce our CO2 emissions to 0.9 metric tons per ton of glass drawn, a 25% decrease compared to 2016.


The objective is to recover 97% of our waste by 2022. By focusing on mapping our waste, we will continue to reduce it and increase its value. Thus, our Verescence Orne and Verescence Somme sites have together managed to reduce the weight of their lacquering sludge by 40% by implementing a pressing process to recover wastewater for reuse in the production process. In 2018, the Verescence group improved its percentage of reused waste by +2%, for a total of 85.9% of recovered waste.


We are working to optimize the water cycle, maximize wastewater treatment, and reduce our consumption. Each site is autonomous with regard to carrying out an exhaustive monthly water consumption assessment by detailing the quantities of water withdrawn, recycled for industrial use and discharged. This data collection allows us to diagnose our consumption performance. In 2018, for example, the La Granja site reduced its water consumption by 20% by optimizing the rules for filling its retention basin and eliminating all unnecessary consumption. This glassmaking site currently consumes less than 1.7m3 of water per ton of glass drawn: this is the best performance observed in the Verescence group. Numerous projects are in progress: converting Mers-les-Bains into a so-called “dry” plant, by collecting rainwater and treating wastewater. In 2018, the group succeeded in reducing its water consumption by 20%, from 4m3 of water per ton of glass drawn to 3.2m3. Our overall objective for 2022: 2.5m3 of water consumed per ton of glass drawn, i.e. -55% compared to 2016.


Verescence was a pioneer 10 years ago in the development of “water-soluble” lacquers. Our intention is now to eliminate the use of solvent- based paints by 2019. To this end, we are raising awareness among our customers and offering alternative solutions. After Spain and the USA, our Verescence Orne site has completely eliminated the use of solvent-based paints.
