Special Issue Information

Dear Colleagues,

This Special Issue will showcase impactful papers focused on applying circular economy strategies along the vehicle life cycle, from manufacturing to recycling.

Over the last few decades, the demand for natural resources has increased exponentially. As a result, ensuring the sustainable use of natural resources is a major concern. Simply looking at the expansion of the list of critical materials published by the European Commission is enough to understand that urgent action is needed.

Vehicle manufacturing is one of the sectors that demands a large quantity and variety of materials. A conventional car is made of more than 50 different types of metals and more than 23 different types of plastics, most of which are crucial in their design but also critical from a sustainability perspective.

Moreover, the replacement of current cars for the new generation of vehicles, which are cleaner, safer, and connected, will increase the demand of critical materials in the manufacturing of some components, e.g., batteries, electronics, microchips, sensors, permanent magnets and touch screens.

As a result, the availability of raw materials is a matter of concern for the automobile industry; therefore, new sustainable and circular approaches must be urgently applied.

This Special Issue investigates how vehicles can become more sustainable regarding raw materials and how scarce resources can be recovered.

We welcome all contributions tackling this broad area of research. Topics of interest include, among others, the following:

  • ELV recycling improvements;
  • Metallurgical processes to recover critical raw materials;
  • Innovative processes for plastic recycling;
  • Eco-design approaches;
  • Next generation of batteries;
  • Reusability and retrofitting alternatives;
  • Opportunities that new technologies offer to improve vehicle recycling;
  • LCA applied to vehicle design, manufacturing or recycling processes;
  • Disassemblability, recyclability and eco-design strategies;
  • Circular economy strategies applied to automobile manufacturing sector;
  • Product end-of-life management;
  • Waste management practices;
  • The economic assessment of circular manufacturing practices;
  • The environmental assessment of circular manufacturing practices;
  • The social assessment of circular manufacturing practices.

I look forward to receiving your contributions to this Special Issue.

A conventional vehicle requires more than 50 different metals in its manufacturing, most of which are critical. Given this circumstance, enhancing sustainability from a raw materials perspective requires improvements in the disassemblability of car parts. This enhancement aims to yield metal-rich fractions, enabling the application of effective recycling processes for the recovery of critical metals. This helps avoid the downcycling that occurs in conventional shredding processes. The present study was undertaken to analyze the challenges associated with disassembling components of significant value due to their metal content. The methodology comprises two distinct main stages: an identification of critical car parts and an assessment of disassemblability. The selection of car parts was determined by the criticality of each one through the thermodynamic rarity indicator. Disassemblability was studied experimentally, encompassing three different levels. This classification defines the stages from extracting parts from the vehicle and obtaining recycling fractions in their purest form: ferrous metals, aluminum, non-ferrous metals excluding aluminum, and plastics. This methodology was implemented on two vehicles manufactured by SEAT: SEAT Leon models II and III. As a result, not only was disassemblability information about these car parts collected, but several ecodesign recommendations were also identified as valuable guidance for future designs, specifically aimed at enhancing metals’ recyclability. In conclusion, it must be acknowledged that contemporary vehicle design often prioritizes cost-effective manufacturing processes. However, this approach may compromise the disassemblability and recyclability of the product. The ongoing transition to electric vehicles necessitates a re-evaluation of design principles, particularly from the perspective of the circular economy. Full article
