With a mixture of hydro- and biomass power, the site has been meeting its energy needs through 100 percent renewable sources. The amount of the booked renewable electricity would satisfy the electricity needs of about 1.500 Italian families and contribute to avoid more 1.500 tons of carbon dioxide emissions annually.

To counteract water scarcity in specific production regions, the eyeglass lenses plant reuses wastewater from operations processes for uses with lower water quality requirements. This results in an annual avoided water consumption of about 100 m³, the equivalent necessary for satisfying the yearly water drinking needs of 100 people.

The Bangalore factory collects rainwater on a surface of 1.200 m² on the factory roof and uses it for lenses production. This way, the avoided consumption of the municipal drinking water, about 690.000 liters a year, is available for the citizens in an area facing water shortage during the drought season.

Renewal of a compressed air system always leads to higher energy efficiencies, but in this case has also triggered the idea in our engineers in Guangzhou to recover the exhaust air generated by reusing it in the warming of our tinting baths: about 90 MWh consumption less, the equivalent of a domestic energy consumption of 30 Chinese families.

For the production of ophthalmic lenses, the production site uses almost 100 percent solar energy instead of fossil fuels.

The plant in the Petrópolis site uses renewable hydropower electricity, allowing the avoidance of about 550 t CO₂ per year, an amount similar to the CO₂-fixed by a wood of 400 trees.

The plant in Hebron has partnered up with a local business from the automotive industry. The partnership allows reusing the spent alcohol from the lenses production process as a raw material for the manufacturing of new alcohol-based products. Every year about 150 kg of potentially harmful volatile organic compounds can be therefore recycled.

With an investment of more than $1 million, production in Tonsley is being converted from wet-edging of lenses to dry-edging with CNC-controlled machines. In this way, no wastewater is produced during the production process.
