Filtral
PV installation at Filtral headquarters
The photovoltaic system installed on the hall roof in Burgfarrnbach has been supplying around 90,000 kWh of solar power since the autumn of 2021. This is fed into the site’s own network, where it can then be used directly by Filtral. A total of 41% of the solar power produced is used by Filtral itself (FY 2023/24), while the surplus is sold back to the Infra Fürth public grid as renewable energy.
The photovoltaic system has allowed Filtral to reduce its grid consumption by more than 50% compared with 2020.
The annual CO2 saving amounts to approximately 40 tonnes compared with the German electricity mix. Moreover, this PV system generates enough electricity to supply the equivalent of 30 households.
Sustainable glasses made from recycled material
Filtral will continue to rely on recycled materials when it comes to manufacturing its glasses.
Since as early as 2021, recycled plastics have been used to produce the models offered as part of Filtral’s reading aid collection. We are proud to say that today all plastic frames are manufactured on the basis of 100% recycled material.
In the summer of 2025, 45% of all sunglasses offered under the Filtral brand will have frames made from recycled materials – with either the frame granulate obtained from recycled plastic or the frame made of recycled metal. In many models, recycled materials are also used in the lenses.
Advantages of recycled plastic:
Reduction in the use of fossil fuels
Manufacturing process protects valuable resources and the environment
Reduced waste
EcoVadis sustainability rating
In March 2024, Filtral was awarded a gold medal by EcoVadis for its commitment to sustainability. This result places Filtral in the top 5% of companies to have been evaluated in the past 12 months.
EcoVadis is the global standard for corporate sustainability ratings. The evaluation comprises 21 sustainability criteria covering four core thematic areas: the environment, employment and human rights, ethics and sustainable procurement. Around the world, more than 125,000 companies have been assessed to date. Ratings awarded by EcoVadis are based on international sustainability standards, such as The Ten Principles of the UN Global Compact, the conventions of the International Labour Organization (ILO), the Global Reporting Initiative (GRI) standard and the set of international standards for social responsibility under ISO 26000. As such, the corporate sustainability ratings offer evidence-based analysis of the performance of the company in these areas, in addition to an achievable roadmap for continuous improvement.
Primetta
As is the case with Filtral, Primetta also makes use of recycled materials to increase the sustainable credentials of the sunglasses and reading glasses it offers. In terms of the plastic glasses, the frame granulate is obtained from recycled plastic. Both the collections of sunglasses and reading glasses are made from 43% recycled material – and the trend here is rising each year.
As far as packaging is concerned, Primetta relies on tissue paper: we do not use polybags at all for our reading glasses, while we have cut our usage of these by 80% for sunglasses.
