MUNICH, Germany — BMW Group is going green with the color blue.
BMW gave a nod to sustainable tire and rubber technology at the launch of its i Vision Circular concept car, billed as "a compact BMW for the year 2040 that is focused squarely on sustainability and luxury."
The four-seater electric vehicle (EV) has been designed to circular economy principles, with a particular focus on the use of secondary materials, BMW said at an IAA Mobility 2021 event.
These materials, such as recycled aluminum and secondary steel, can "bring about a major improvement in a vehicle's carbon footprint, especially on the supply chain side," the company said.
BMW said its vehicles currently are manufactured using nearly 30% recycled and reused material on average, whereas the "secondary first" approach is intended to increase this figure to 50%.
Moreover, the EV is said to be optimized for closed materials cycles, with "100% use of recycled materials and 100% recyclability." This involves using materials that have already completed a product life cycle, alongside certified bio-based raw materials, BMW said.
Another aspect is the use of a small number of different mono-material groups with connections that can easily be undone to aid recycling. So, instead of bonded connections or composite materials, BMW's concept EV uses connection types, such as cords, press studs and quick-release fasteners.
