Sustainable production

Climate neutrality as a goal

A manufacturer of intelligent lighting solutions such as TRILUX can undoubtedly generate the greatest effects in favour of climate and resource protection via its efficient and sustainable products. However, all processes in production, administration and transport also offer potential for more sustainable management. This is why TRILUX is working systematically to optimise them and to minimise their impact on environment and climate. Energy efficiency, CO2 emissions, water consumption, reducing waste and avoiding environmental risks are important approaches here.

Water as a precious commodity

Water consumption is measured at all locations and continuously reduced through measures. Waste water is discharged exclusively into municipal sewage systems in accordance with official regulations. In Arnsberg, a water treatment plant is operated for this purpose to adjust the pH value.

No infringements and sanctions in 2019

The minimum standard for the TRILUX Group with regard to climate and environmental protection consists of the respective legal requirements at the locations. All relevant regulations are continuously monitored and their compliance is checked by regular audits. These measures are reliably effective. Throughout the TRILUX Group, no statutory violations were registered in 2019, nor were sanctions imposed in the area of environmental protection.The sites Arnsberg, Alhama de Aragón and Zaragoza in Spain have a certified environmental protection management system in accordance with ISO 14001. Arnsberg also has and a certified energy management system in accordance with ISO 50001.

Permanent balancing and optimisation

As part of its environmental reporting, TRILUX continuously records values on energy consumption, greenhouse gas emissions, water withdrawal and waste generation. This database is used to identify potential for improvement and to derive realistic objectives for even greater sustainability. 

The statistics show: energy and water consumption are declining overall. Any deviations can be explained, e.g. at the Cologne location due to the expansion of the site.

Numerous successful measures

This positive development was achieved through a variety of measures. The spectrum ranges from energy efficiency measures for machines and buildings and the digitalisation of all order-related data to reusable packaging along the entire value chain. Several positive effects were achieved at once, for example, by introducing paperless contract production. On the one hand, all paperwork (test instructions, assembly instructions, drawings, packaging instructions, TQ control certificates, current value tables, etc.) is no longer required, and on the other hand, considerable savings are released in internal logistics because parts are now delivered precisely to the piece and there are no more returns to the warehouses.

In addition to the introduction of digital order data, TRILUX put many other sustainable ideas into practice, of which only a few will be listed here:

  • Solvents must be used for degreasing and cleaning of metal parts. These solvents are reprocessed in a closed circuit with fully automatic filter systems and returned to the cleaning process.
  • The oil sludge resulting from the degreasing of the steel sheets is retained in separators. Residues are disposed of separately from other types of waste.
  • Painting is carried out with solvent-free powder coatings.
  • Cooling systems with closed water circuits reduce the water requirement considerably.
  • In the manufacture of plastic luminaire covers, the plastic waste produced is recycled and returned to the production process.
  • Hot water boilers with exhaust gas heat consumers and automatic, pressure-dependent and speed-controlled circulation pumps lead to considerable energy savings.
  • At the Arnsberg location, TRILUX operates a photovoltaic system with 6,240 modules which can deliver over 500 kW (peak) and supply more than 100 homes with environmentally friendly electricity.

Well on the way to Group-wide climate neutrality

Having already achieved so much, large goals can be set with determination. TRILUX aims to achieve climate neutrality at all locations worldwide by 2025. Direct and indirect emissions will already be reduced by at 10% per year in the coming years. Sustainable production will contribute to this as much as sustainable TRILUX products and business models.
