Remanufacturing Remanufacturing is the process of restoring a used product to the specifications of the original manufactured product using a combination of reused, repaired and new parts. It is a sustainable way to preserve resources, reduce environmental impact and waste. We are actively scaling our remanufacturing capabilities, with dedicated projects now successfully underway in some of our factories. Our selected facilities have launched their first full-cycle remanufacturing initiatives, recovering and upgrading existing luminaires to a near-new condition. The process involves careful inspection, cleaning, and reassembly using a mix of existing components and the latest energy-efficient technologies - including LED upgrades and smart control integration. In one of our remanufacturing projects, 300 existing luminaires were recovered and upgraded with new LED components while retaining most of their original structures. By keeping the housings and mechanical parts in perfect working order, we were able to conserve around 65% of the materials originally used to manufacture these luminaires. This approach drastically reduced
Retrofit LED kits improve safety with 50% less energy in CNA Tunnel
The Contournement Nord d’Angers (CNA) tunnel, a twin-tube, two-lane passage on the A11 motorway that facilitates traffic between Nantes and Paris. It was lit by 1,068 PF5 luminaires installed in 2008. After more than 15 years in service, Cofiroute, the concessionaire and operator of the tunnel, decided to upgrade to LED lighting as part of its sustainability commitment to reduce energy consumption and improve uniformity in the tunnel. Originally designed for discharge lamps, the PF5 can be retrofitted with LEDs to deliver a higher light output with less energy, lower maintenance costs and reduce carbon emission. As the PF5 luminaires were still in excellent condition, Cofiroute chose to retrofit rather than replace them. This allowed the luminaire bodies, junction boxes and distribution network to be preserved. We redesigned the tunnel lighting installation to create a curve as close as possible to the CETU (French Centre for Tunnel Studies) curve for an efficient and economical installation. Using our high performance LED optics, we reduced the number of luminaires needed to light this 1.7km tunnel to 925, further reducing energy and maintenance costs. Now equipped with the latest generation white LEDs, the PF5 luminaires deliver a bright light with exceptional colour rendering to optimise the visual perception of drivers and improve safety in the tunnel . The energy efficient LEDs have reduced the total power of the installation by more than 50%, significantly reducing the energy consumption. By reusing the existing luminaires, Cofiroute has minimised the resources and energy needed to relight this tunnel, contributing to a more circular economy.
the need for new raw materials, avoided unnecessary waste and the environmental impacts associated with manufacturing and transporting entirely new products, thus significantly minimising the environmental footprint of the project. By carefully integrating advanced LED technology, we have extended the life of these luminaires and improved their energy efficiency - all while maximising the reuse of existing resources. This and other real-world successes demonstrate that remanufacturing can deliver both environmental and economic benefits. It maximises the value of existing equipment, minimises material waste and offers cities and customers a sustainable, futureproof solution to their lighting needs.
