100% Renewable Energy in Varese¹

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.

Reuse of Wastewater in Tijuana²

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.

Water savings through new manufacturing process in Tonsley⁸

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.

Turn waste into raw material in Hebron⁷

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.

Renewable energy procurement in Petrópolis⁶

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.

Rainwater Recycling in Bangalore³

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.
