Sustainable production at LTT
Sustainability has become a core issue in modern society. It focuses on conserving resources and meeting present needs without placing excessive strain on the systems involved. Ensuring these cycles remain regenerative is crucial for the long-term, environmentally responsible use of resources.
Sustainability plays a key role in many areas, whether in the production of goods, energy policy or personal lifestyle choices.
At LTT, we are committed to environmentally sound practices as part of our contribution to a sustainable future.

Quality
With our DIN ISO 9001 and DIN ISO 14001 certifications, we uphold our high quality standards while ensuring environmental sustainability.
Quality management (DIN ISO 9001)
Efficient and reliable processes are essential for manufacturing high-quality products. By streamlining our production workflows, we can avoid unnecessary scrap and reduce our energy consumption and material wastage. This not only supports sustainable resource utilisation but also results in efficient production processes that meet customer expectations.
Environmental management (DIN ISO 14001)
Our workflows are characterised by efficiency and environmental awareness. We prioritise resource conservation and the implementation of ecologically sound processes. Through the corresponding measures, we help to minimise environmental pollution and promote the sustainable use of resources. We strive to design our processes and workflows in harmony with nature, recognising our responsibility to future generations.
Energy
Processing plastics is energy-intensive – they must be melted, shaped and then cooled. However, compared to the production of steel or aluminium parts, plastic processing is significantly more energy-efficient. That said, generating energy from fossil sources results in CO₂ emissions.
To keep our CO₂ emissions as low as possible, we focus on the following:
- Selecting energy-efficient injection moulding and thermoforming machines whenever new equipment is procured.
- Using waste heat from production to heat our facilities.
- Implementing energy management systems to further reduce our energy consumption.
Supply chain
We place a major emphasis on the quality and origin of our raw materials. For this reason, we source our pure-grade raw materials exclusively from reputable manufacturers, preferably within our region, who adhere to recognised quality and environmental standards. We do not use raw materials of questionable origin. This approach enables us to maintain short transport routes and minimise unnecessary CO₂ emissions.
Sustainability and environmental protection are also central to our production processes. Plastic waste, such as sprues or edge trimming, is collected and sorted by type, re-ground and returned to the production cycle. This allows us to achieve an internal reuse rate for plastics of over 95%. Additionally, all our products are clearly labelled to ensure they can be sorted correctly for material or energy recovery.
We also offer our customers the option of bio-based plastics, provided this is both technically feasible and environmentally beneficial. This means we can manufacture bio-based moisture-proof luminaires, further contributing to environmental conservation. Sustainability is at the core of everything we do, and we remain committed to using resources responsibly and in an environmentally sound manner.
