Sun lenses with Bio-based materials

Two main renewable factors contribute to the CO2 reduction of the manufactured lens:

1. The use of a mass balanced bio-based material
2. The purchase of renewable electricity

In the lens production process, 39% bio-based raw materials (from the waste produced by the agricultural industry) partially substitute the fossil-based material throughout the value chain and 100% of renewable electricity is used.

The carbon footprint of this lens has been reduced by 50% compared to a fully fossil-based manufacturing process.*

_{*The statement refers to a cradle-to-gate system embodying all upstream activities and including all processes at the Italian production site related to the manufacturing of the polyamide lens/shield/goggle. Global warming effect from end-of-life (lens disposal) is not included in the evaluation. With reference to the sustainable polyamide lenses manufactured in the Italian production plant, ISO14067:2018 GHG emissions calculation rules have been applied making use of the most recent and available data (from October 2020 to September 2021) for the Life Cycle Inventory phase (collection of process inputs and outputs data) that include effects in the value chain of biogenic carbon sequestration.}
