saving CO2 emissions mass-balanced** polycarbonate per lens ** Mass balancing is a bookkeeping method that is used to record and track the mass flows of plastics, for example, along the entire value creation chain. In the manufacturing process, some fossil-based raw materials are replaced by more sustainable alternatives, for example through the use of biomass or recycled raw materials. The mass balancing approach enables manufacturers to verify the use of bio-based raw materials or recyclate within a balance sheet period and to mathematically allocate the bio-based or recycled content to a proportion of the plastics produced, resulting in a material with a significantly lower CO2 footprint. However, the exact proportion of bio-based or recycled material in the end product can no longer be precisely determined. At uvex, mass-balanced material is used in the lenses of the planet models, enabling a significant reduction in their CO2 footprint. By purchasing mass-balanced polycarbonate, uvex is helping to replace fossil-based raw materials with bio-based materials. 13 % 9916000 100 % 117
