Since 2011, an effort to begin to understand the emerging issue of wastes containing nanomaterials has started. The use of various nanomaterials has been growing exponentially in recent years and an increasing number of products now use these materials, delivering a number of benefits to consumers. As a consequence more and more of these materials appear in different waste streams. However, very little is known about the way nanomaterials behave in different waste treatement operations. There is therefore a significant need for research and OECD has been mandated to explore this issue in order to facilitate governments’ decision making in this area.

OECD activies therefore focus on sharing information and coordinating research efforts between OECD member countries.
