The double materiality assessment performed by Nexans has shown that mining operations for copper production have significant environmental impacts on ecosystems, including soil, air and water pollution, water use, and biodiversity loss. The two main suppliers of copper cathodes for Nexans’ facilities in Lens (France) and Montreal (Canada) have also validated this materiality assessment of the copper value chain, during interviews. By substituting primary resources with secondary resources, such as recycled copper, we can reduce our dependency on natural resources, shrink our environmental impact, and decarbonize our cable systems, leveraging Nexans’ end-to-end vertical expertise.

Helping to build a circular economy is one of the main ambitions of the Group’s sustainability policy. It encompasses strategies to preserve resources, extend product life spans or reuse products, and reduce waste. Our policy applies to all Nexans entities around the world.

Because circularity is increasingly central to the Group’s strategy, in January 2023, Nexans created a circular economy technology platform, working with an ecosystem of global industrial, academic and advisory stakeholders:

• universities and research labs, such as Université Claude Bernard Lyon-1 (CP2M, IMP and ISA) and Université Jean Monnet (IMP St Etienne), to develop technical building blocks for the recycling of polymer waste, and ENSAM and Institut Laplace, to increase the life span of cables
• industrial players, such as Suez, Arkema, Elkem, Hutchinson, Michelin and Trelleborg Industrie (via the PYROCA and RENOV collaborative projects funded by ADEME), to develop recycling technologies for complex polymer waste
• suppliers of non-ferrous metals and polymers, for the testing and certification of low-carbon circular resources
• industrial companies, to assess new circular economy technologies
• strategic customers, to develop the circularity of products and services and explore opportunities for reuse

Customized recycling solutions

We not only manufacture cables, we also recycle them responsibly. Choosing Nexans’ recycling services means getting a financial return from end-of-life cables as well as helping to protect the environment.

Recycling with Nexans also offers these advantages:

• Innovative technology for copper and aluminum cable grinding
• Turnkey logistics solutions
• Full transparency and traceability of all operations

Responsibly produced copper certified by the Copper Mark

In 2023, the Group became one of the first cable manufacturers to receive the Copper Mark, attesting to the copper industry’s contribution to the UN’s Sustainable Development Goals (SDGs). The rigorous Copper Mark assessment process investigates each copper production site to independently verify the application of responsible practices.

Nexans’ metallurgical facilities in Montreal (Canada) and Lens (France) have both been awarded the Copper Mark. They were assessed against a set of 32 internationally accepted sustainability criteria, in line with environmental, social and governance standards. The Group is one of the first cable and wire rod manufacturers and one of the first copper rolling mill operators in North America and Europe to earn this certification. We will shortly be launching the Copper Mark assessment process for our two other mills, in Peru and Chile.

This Copper Mark recognition highlights Nexans’ global leadership in sustainable electrification. As a member of the UN Global Compact since 2008, the Group upholds ten fundamental principles in the areas of human rights, labor practices, environmental protection and anti-corruption. We have also incorporated Sustainable Development Goals (SDGs) into our corporate social responsibility priorities. And in 2023, Nexans pledged to reach net-zero emissions by 2050, in alignment with the Science Based Targets initiative (SBTi).

Copper recycling

Nexans is working to increase the amount of recycled copper used in our cables to reduce natural resource consumption and shrink their environmental impact. By vertically integrating scrap metal into copper processing, we can incorporate a significant share of recycled copper into our upstream production. The Group aims to include 30% of recycled content in copper bars produced at the Lens facility by 2030.

In 2023, approximately 33,600 metric tons of copper scrap were reused in Nexans’ casting facilities in Canada, France and Peru, covering about 5.4% of the Group’s needs.

In other countries, the Group has also undertaken to send metal waste to suppliers for recycling. These suppliers then incorporate the recycled metal into new bars sold to Nexans.

Thanks to this copper recycling capacity, we can reduce our carbon footprint while preserving natural copper resources. However, availability of copper scrap is a crucial prerequisite to increasing the recycling rate. We are working with the Group’s customers to expand the collection of copper scrap.

Reintegration of recycled materials

Recovery of aluminum scrap

The other main nonferrous metal used in cable manufacturing is aluminum. The Group obtains aluminum scrap from its cable manufacturing and recycling processes and sells it to aluminum suppliers. Nexans then repurchases aluminum with recycled content.

At the end of 2022, along with its German partner Trimet, an aluminum production and recycling company, the Group launched Europe’s first aluminum rod containing 10% of recycled aluminum. The process used to recycle aluminum cable scrap uses only a fraction of the energy needed to produce primary aluminum. Nexans used this innovative recycled aluminum rod, supplied by Trimet, to manufacture new power cables.

Around 74,000 metric tons of aluminum were used in new cable production in 2023.

Recycling of polymers

Several initiatives are also under way to better recover plastic waste, such as PVC, PE, XLPE and filled polymers. The aim is to move from a linear model to a circular one, where used materials are reintroduced into cable production. In December 2022, Nexans obtained a large grant from ADEME, the French Environment and Energy Management Agency, to explore the recyclabilty of polymer waste with other industrial and academic partners. Significant research was undertaken in 2023 to explore the recycling of XLPE and elastomer waste.

Recycled polymers are also used in packaging, such as Mobiway cable drums made of 100% recycled polypropylene and the various films used to wrap cable spools. The Group is a member of the Circular Plastic Alliance and is participating in a pilot project in Belgium that collects plastic film from customers for recycling and reuse in new plastic film.

Ecodesign and data transparency

Ecodesign is the design of products and services in a way that minimizes their environmental impact throughout their life cycle. Nexans applies ecodesign principles in two ways:

• using a qualitative approach, considering every stage of our products’ life cycle
• using a global, quantitative approach based on life cycle assessments performed in compliance with ISO 14040 and ISO 14044

Life cycle assessments quantify the impacts of design choices at every life cycle stage (from the extraction of the necessary raw materials to manufacturing, distribution, installation and usage, through to end-of-life management). The Group has more than 15 years of experience in conducting life cycle assessments. This analysis helps Nexans identify areas where products can be improved to reduce their environmental impact, for example, by substituting primary resources with secondary resources.

The Group communicates the results of our products’ life cycle assessments using the Product Environmental Profile (PEP) method developed by the PEPecopassport® program, of which Nexans France is a founding member. It meets ISO 14025 criteria on Type III environmental declarations, which report on a product’s environmental performance.

The Product Environmental Profile aligns with the following standards:

• a recognized methodology based on the ISO 14040 series, which describes the principles, framework, requirements and guidelines for life cycle assessment best practices
• product category rules developed jointly with other electrical and electronic equipment manufacturers, in line with ISO 14025
• an internationally recognized methodology (CML) for assessing life cycle impacts, using indicators recommended by French standards EN 50693 and EN 15804, which include 15 mandatory environmental indicators (global warming, water scarcity, water pollution, air pollution, etc.) as well as 17 mandatory indicators for monitoring energy consumption, water consumption and waste

Each PEP is checked by an independent verifier holding PEPecopassport® accreditation.

At the end of 2023, Nexans had recorded 288 PEPs covering more than 5,600 product references used in different markets around the world, including France, Belgium, Italy, Canada, Sweden and Chile. 16.8% of Nexans 2023 sales were covered with a third‑party verified PEP. In France, these environmental declarations are mainly used to meet building certification requirements, such as for the E+/C- label for positive-energy, low-carbon constructions.

Training in these areas – life cycle assessments, the Product Environmental Profile and ecodesign – was completed by 34 employees in 2023 (56 in 2022).
