1. Benefits of Circular Economy in Auto Parts
Environmental Impact
Switching from a linear to a circular economy in auto parts delivers measurable environmental benefits. For example, refurbishing an engine generates just 15% of the emissions required to produce a new one. Similarly, remanufacturing critical components like combustion engines can cut Global Warming Potential by up to 79%. These reductions come from minimizing the need for mining and processing raw materials.
Electric vehicle (EV) battery production is a prime example of how circular practices can address sustainability challenges. In December 2022, Northvolt, a Swedish battery developer partly owned by Volkswagen, created battery cells using recycled nickel, manganese, and cobalt. These materials were recovered from waste, and the company has already secured over $55 billion in contracts from major clients like Volvo and Polestar. Meanwhile, Bolder Industries achieved over a 90% reduction in greenhouse gas emissions and water usage by producing carbon black alternatives from old tires by 2025. In Europe, remanufacturing keeps approximately 150,000 tons of materials in use every year, ensuring access to scarce resources like rare-earth elements and other Critical Raw Materials. These environmental gains also set the stage for substantial economic opportunities.
Economic Implications
The cost savings from circular practices aren’t just good for the planet - they’re also good for business. Remanufacturing can lower production costs by 40% to 60% compared to manufacturing new parts, boosting profit margins. On the consumer side, remanufactured parts are typically 45% to 65% cheaper than new ones, and they still come with warranties. By 2030, the automotive industry could unlock between $475 billion and $810 billion in economic value through remanufacturing and material recovery.
"Remanufacturing can reduce costs by 40 to 60 percent, directly boosting margins versus newly manufactured parts." - McKinsey
The scale of these efforts is already significant. In 2024, LKQ Corporation processed 735,000 vehicles worldwide and sold nearly 12 million salvaged and remanufactured parts. This thriving secondary market not only reduces reliance on volatile raw material supplies but also helps mitigate risks from shortages.
Operational Feasibility
Modern technology has made circular practices more practical and efficient than ever. For instance, Novelis implemented advanced scrap-sorting systems in 2024 to recover high-quality aluminum from old vehicles, which is then reintegrated into the production chain. Tools like AI-driven scrap sorting, IoT-enabled predictive maintenance, and blockchain for tracking materials in real time are revolutionizing how companies manage their resources.
The market for remanufactured automotive components is expected to grow significantly, from $27 billion in 2022 to $42 billion by 2030. Renault Group's "Refactory" initiative, launched in September 2025, focuses on refurbishing vehicles to extend their lifespan. The company has also committed to increasing vehicle usage rates by at least 20% through innovative mobility services. With recycling efficiency for vehicles projected to rise from 78% today to 97% by 2040, circular operations are becoming not only feasible but also a standard part of the automotive industry.

2. Challenges of Circular Economy in Auto Parts
Economic Implications
The promise of savings through circular practices is appealing, but achieving profitability is no easy feat. Collecting and processing used auto parts requires hefty initial investments in specialized facilities. On top of that, the unpredictable timing and condition of incoming used parts create logistical headaches. These issues often lead to higher costs from overtime labor or expedited shipping. Pricing these parts is another hurdle. Differences in product age, condition, and limited quantities make it nearly impossible to gauge price elasticity accurately.
"Remanufacturing undoubtedly makes logistics, pricing, and operations more complex" - McKinsey
Adding to the complexity, the market for high-quality secondary materials is both limited and volatile, leading to long-term sourcing challenges. Navigating these financial and operational difficulties requires advanced systems to maintain profit margins. These hurdles, both economic and logistical, make it tough for businesses to fully embrace circular models.
Operational Feasibility
Modern vehicles pose significant technical challenges for recycling. Each car contains around 30,000 components, many of which are made from multi-material composites or are permanently fused together. For instance, vulcanized rubber in tires forms chemical bonds that cannot be reversed, while fiber-reinforced plastics degrade during recycling, losing their original properties . These limitations mean that over 80% of end-of-life plastics in the U.S. end up in landfills.
Additionally, the shift from mechanical to electronic components complicates remanufacturing. Tasks like software updates, sensor testing, and electronic diagnostics require specialized skills, clean-room environments, and advanced training. Robert Casper from the University of Bayreuth highlights the confusion surrounding the classification of used parts:
"The interpretation of the status of cores is often a matter of discussions. Can cores be seen as a used spare part? As old metal? As a scrap part? As hazardous waste?"
This lack of clarity makes logistics and regulatory compliance even more challenging. While Europe collects 89% of end-of-life materials for recycling, inefficiencies reduce the effective recycling rate to 78%. These technical and regulatory hurdles create additional challenges for circular practices.
Environmental Impact
Circular practices often come with environmental trade-offs. Recycling facilities can generate pollution and must handle hazardous materials like oils and battery chemicals from end-of-life vehicles. Additionally, many materials undergo "downcycling", where their quality diminishes, limiting their reuse in automotive applications .
Switching to bio-based materials isn't a perfect solution either. For example, while natural rubber can enhance biodegradability, its rising demand has contributed to deforestation in Southeast Asia. Electric vehicles, though offering lower lifetime emissions, have a more carbon-intensive production process due to the mining of battery metals and their heavier weight.
Currently, only 3% of plastics used in car manufacturing are recycled into new products. Mechanically recycled polypropylene, for instance, loses 15% to 20% of its strength compared to virgin materials. The EU's upcoming requirement for new vehicles to include 25% recycled plastic by 2038 will demand 1.4 billion kilograms annually, but projections suggest only 800 million kilograms of suitable recyclates will be available. These challenges highlight the environmental complexities tied to circular practices in the automotive industry.
