Metals – an indispensable resource

Whether in smartphones, electric vehicles, wind turbines, or medical devices, metals and metallic compounds are present in nearly all modern devices and applications. They form the often invisible backbone of emerging technologies, industrial processes, and energy systems, and are indispensable to today’s society.

Key metals and alloys – and their applications:

Copper

enables electrical conductivity in cables, chargers, and electric motors

Aluminium

provides lightweight and durable housings for vehicles and devices

Lithium

enables energy storage in batteries for smartphones, laptops, and electric vehicles

Indium

is used in touchscreens and modern display technologies

Cobalt, nickel, manganese

enhance battery performance and extend service life

Rare earth elements (e.g. neodymium, dysprosium)

are used in high-performance magnets for wind turbines and electric motors


In our daily lives, we rarely think about the role these materials play. We often replace our devices after only a few years—not necessarily because they no longer work, but because batteries wear out or newer models become more appealing. As a result, valuable raw materials end up forgotten in drawers, discarded with waste, or only partially recovered through recycling. At the same time, many of these resources are limited, and their extraction is associated with significant environmental impacts.

What if we used our resources more wisely?

Instead of continuously extracting new raw materials from increasingly remote parts of the world, we could keep the materials already contained in existing products in circulation, reuse them in new applications and preserve their value for longer.

This means more than simply collecting, sorting and recycling end-of-life products. A circular economy starts much earlier in a product’s life cycle. Products should be designed from the outset to be modular, repairable and easy to disassemble, helping to conserve resources and extend their useful life.

The benefits of this shift affect all of us:

  • For the environment: Less environmental damage from resource extraction and significantly lower emissions during manufacturing and processing.
  • For the economy: Lower material costs, greater resource efficiency and reduced dependence on vulnerable global supply chains.
  • For society: Longer-lasting products, easier repairs and a more responsible use of our planet’s resources.

Yet, as logical as these solutions may seem, putting them into practice remains challenging. We often lack a clear understanding of how circular systems work and what happens to materials once products reach the end of their life.

UniGR-CIRKLA helps make these complex processes tangible. The project provides knowledge on how circular economy principles can be integrated into products, buildings and infrastructure, as well as into many other areas of everyday and professional life. It brings together cutting-edge research in materials science, engineering, georesources and economics with practical examples from industry, businesses and local initiatives across the Greater Region spanning Luxembourg, Germany, Belgium and France.

It aims to create a shared understanding of how metals and materials can remain in use for longer through repair, reuse and recovery, and which decisions are key to shifting from a linear to a circular system—from waste to value, from short-lived products to long-lasting resources.
