Sustainability
Our daily business is driven by our mission to drastically reduce energy demand in Europe through efficient and circular lighting, to increase the profitability of businesses and to promote a circular economy. That is why we produce exclusively in Germany and design our GLT TUBES to be energy-efficient, durable and recyclable. As a family business, we have geared all our business activities and processes towards maximum sustainability. In this way, we want to make an important contribution to achieving the European climate targets. This sustainability strategy is firmly anchored in our company DNA.
Quality and maximum energy efficiency
Our brand product, the GLT TUBE, is ENEC-certified according to the international standard IEC/EN 62776 for LED tubes for temperature ranges between -40°C to +70°C and can claim the title of "best technology available on the market" according to the current eco-design guidelines of the EU. This means immediate savings of up to 80% in operating costs and CO2 emissions compared to conventional fluorescent tubes. Thanks to this outstanding quality and durability, we have been offering intelligent and flexible rental models for more than 10 years. These enable immediate savings without tying up capital.
Environmental Product Declaration EPD
Sustainability must be assessed. This is why the GLT TUBE has been certified in the form of an EPD (Environmental Product Declaration) in accordance with international standards ISO 14025 and EN 15804. We disclose all the energy and environmental impacts of our GLT TUBE. Whether raw materials, product components, production process, transport or recycling - every step is verified by independent auditors and the environmental impact is analysed on the basis of life cycle assessments over the entire product life cycle. You can find the EPD for the GLT TUBE here.here.
Benefits of using the GLT TUBE
There are numerous advantages for B2B customers, local authorities and planners when using the GLT TUBE with EPD certificate:
- GLT TUBE is certified as an LED light source for sustainable construction (recognised as a sustainability certification system for buildings).
- GLT TUBE is an important building block for sustainability strategies for companies, organisations and the public sector.
- GLT TUBE as a light source enables certified measurement and evaluation of the energy and environmental impact of lighting and increases the value of the property.
Environmental certificate for Aspach site
GLT has successfully achieved ISO 14001:2015 environmental certification at its production site in Aspach, underpinning our commitment as a family-owned company to aligning all business activities and processes with maximum sustainability. We offer our employees a healthy, attractive environment with a wide range of training opportunities.
Made in Germany
Since 2010, we have been developing and producing our efficient and sustainable GLT TUBES exclusively in Germany according to the highest quality criteria. This means that we adhere to the strict European regulations on energy efficiency, circular economy, freedom from pollutants and reparability of products out of conviction. Our production site in Aspach near Stuttgart is also subject to the strictest environmental criteria.
Circular Lighting
The GLT TUBE is manufactured in Germany and is 90% recyclable. Whether you buy or rent - at the end of the service life or at the end of the rental period, we take back the GLT TUBES, repair them or return the raw materials to the cycle. The reusable system of the GLT TUBE is unique on the LED market and directly benefits our environment.
The life cycle assessment of the GLT TUBE convinces EnBW
A study completed in May 2022 by the Fraunhofer-Institut für Bauphysik IBP on behalf of EnBW Energie Baden-Württemberg AG analyses the advantageousness of the GLT TUBE using the example of the GLT TUBE 150 in the impact category EF3.0 Climate Change compared to comparable competitor products. The aim of the study was to develop the life cycle assessment of the GLT TUBE in order to be able to use it in the overall economic efficiency calculation and implementation concepts at EnBW Baden-Württemberg AG. Compared to fluorescent tubes, the GLT TUBE is already beneficial after 15 days, compared to LED tubes after 101 days. The energy efficiency and resource efficiency of the GLT TUBE is particularly emphasized. You can see a summary of the study here.study here.
