Metal Recycling the challenge of sustainable development at the beginning of the 21st century has become a systemic one, with environmental, social and economic dimensions on an equal footing. UNEP and the UNEP-hosted International Resource Panel consider that our contributions also need to be systemic, for example through the promotion of resource efficiency, improved materials recycling and life-cycle thinking.

The increasing demand for metals in the course of the last century, putting permanent pressure on natural resources, has revealed that metals are a priority area for decoupling economic growth from resource use and environmental degradation.
The imperative of decoupling will become even more pressing in the future with global demand for metals on the rise: In developing countries due to rapid industrialization and in developed countries due to modern, metal intensive technologies that are crucial not only but especially for the transformation towards green technologies.
Ensuring appropriate levels of supply while reducing the negative environmental footprints will, therefore, be essential on our way towards a global green economy. In this regard, recycling and thus resource efficiency plays a crucial role, as it decreases the necessity to fulfill the demand by exploiting our natural resources further.
Using secondary resources temporarily locked up in so-called “urban mines” hence decreases not only the environmental impacts associated with mining but also decreases the release of – partly toxic – wastes into the environment.
Taking into account that most modern technologies rely on ‘critical’ elements, which are not abundant in nature, it is of crucial importance to preserve and reuse them as much as possible.
The International Resource Panel’s working group on Global Metal Flows contributes to the promotion of an international sound material cycle society by providing a series of six scientific and authoritative assessment studies on the global flows of metals.
To achieve the best scientific results, it cooperates with a number of actors, including metal industry associations. The present, the report builds on the findings of the two previously published assessments of metal stocks in society and recycling rates, which came to the conclusion that despite huge metal “mines above ground”, recycling rates remain low.
It aims at leveraging the secondary production of metals through a close analysis of the necessary conditions and enablers of recycling.
