Circular Economy Applied to the Automotive Sector
The linear model on which the automotive industry has historically relied, based on the sequence of production, use, and disposal, today shows all its environmental and economic limits. Circular economy offers a concrete alternative, capable of rethinking the vehicle’s lifecycle at every stage, from design to end of life. The scope of this transformation is enormous, as the automotive sector is one of the most complex manufacturing industries, with a significant impact in terms of resource consumption and waste generation.
Innovation in Design and Materials
The circular transition begins already at the design stage. More and more car manufacturers are adopting principles of modular design and easy disassembly. This facilitates the separation and recovery of components at the end of the vehicle’s use. The adoption of recycled and recyclable materials, as well as the development of biobased plastics and low-emission steel, reduces dependence on virgin raw materials and strengthens the resilience of supply chains. In some cases, companies are already introducing components made entirely from recycled plastic or textiles derived from regenerated fibers, showing that circular innovation can be integrated without compromising quality.
The Value of Reuse and Remanufacturing
A fundamental part of the circular strategy in the automotive sector concerns remanufacturing components. Engines, gearboxes, brakes, and electronic control units are recovered, refurbished, and reintroduced to the market with performance equivalent to new. This approach not only drastically reduces waste, but also creates new business opportunities based on advanced maintenance services and dedicated remanufacturing supply chains. Some groups, such as Bosch and LKQ, have built entire divisions dedicated to remanufacturing, with significant economic impact and considerable resource savings.
Batteries and Electric Mobility
The rise of electric mobility makes batteries a critical node for the circular economy. Major groups have already established closed-loop supply chains to recover critical materials such as nickel, cobalt, and lithium, reinserting them directly into production cycles. These processes significantly reduce environmental impact and help ease geopolitical pressure linked to raw material supply. Moreover, there is growing interest in so-called “second life,” using batteries no longer suitable for automotive applications in stationary energy storage, extending their utility and improving overall system efficiency. Companies such as BMW and Volkswagen have already launched pilot plants capable of recovering up to 95% of battery materials. This paves the way for a future where batteries are designed from the start to be fully circular.
Three Concrete Examples of Circular Economy in the Automotive Sector
Renault – With the Refactory in Flins, near Paris, Renault has created the first European plant entirely dedicated to the circular economy. In this facility, engines, gearboxes, and electronic components are remanufactured and put back on the market almost as new. This process delivers energy savings of up to 70% compared to producing them from scratch. The Refactory also hosts material recycling activities and projects aimed at giving electric vehicle batteries a second life.
BMW – The German group focuses on so-called circular design, which means designing cars with their future disassembly and recycling already in mind. The BMW i Vision Circular concept is an example: a compact car built entirely from recycled materials and designed to be 100% recyclable. Today, BMW already uses recycled plastics and metals in its production models and has launched partnerships to recycle electric vehicle batteries, recovering up to 95% of valuable metals such as lithium, nickel, and cobalt.
Stellantis – In Turin, at the Mirafiori complex, Stellantis has opened its first Circular Economy Hub, where engines, gearboxes, and batteries are remanufactured, and used vehicles are reconditioned. The company is also advancing “second life” projects for electric vehicle batteries. At Rome Fiumicino Airport, for example, old batteries have been transformed into a large renewable energy storage system, capable of powering part of the infrastructure and reducing emissions.
New Business Models and Services
The circular economy is not limited to the technical dimension of production and recycling, but also reshapes consumption models. The concept of exclusive ownership of a car is gradually giving way to shared-use formulas such as car sharing and long-term leasing. These services, in addition to optimizing vehicle use, encourage manufacturers to ensure greater durability, scheduled maintenance, and recoverability of materials, since the value of the asset does not end with the sale but accompanies the entire lifecycle. Another frontier of innovation is mobility as a service (MaaS). It integrates public and private transport on a single digital platform, reducing the total number of vehicles in circulation, and maximizing efficiency.
The Role of Policies and Alliances
The adoption of circular principles in the automotive sector is also supported by European and global initiatives, promoting extended producer responsibility and creating common platforms for the standardization of recycling processes. Alliances between manufacturers, suppliers, and research centers are already developing shared roadmaps to reduce natural resource use and cut emissions of CO₂. The Circular Cars Initiative, launched by the World Economic Forum, is an example of a platform aimed at uniting public and private actors to accelerate the transformation. Likewise, the European Commission is strengthening the regulatory framework through the Green Deal and the Sustainable and Smart Mobility Strategy, pushing for mandatory recycling targets and higher recovery rates.
Future Prospects
The potential of the circular economy in the automotive sector goes far beyond simple recycling. Recent studies estimate that widespread adoption of circular practices could reduce the consumption of raw materials needed to produce vehicles by up to 80%, while global mobility demand is expected to double by 2050. At the same time, the profitability of companies could increase significantly. This is thanks to the valorization of new supply chains, the sale of services, and the optimization of resources. For businesses, the challenge will be to reconcile economic and environmental objectives with consumer expectations, which are increasingly sensitive to sustainability issues.
Conclusion and the Role of Tondo
The automotive sector is at a crucial moment of redefinition. The circular economy represents a unique opportunity to combine industrial competitiveness, environmental sustainability, and technological innovation. From modular design to battery remanufacturing, from material recycling to shared mobility models, the ongoing transformation is no longer optional but a necessity. If pursued with consistency and long-term vision, it could lay the foundation for a new productive and economic paradigm capable of meeting the challenges of our time.
In this journey, organizations like Tondo play a fundamental role. We promote knowledge dissemination, foster dialogue between businesses, institutions, and citizens, and support the creation of collaborative ecosystems based on circular economy principles. Through research, outreach, and innovation activities, Tondo contributes to making the transition more tangible and accessible. This reincorces the awareness that a circular future in the automotive sector, as in many other industries, is not only possible but already underway.
