The European Chemicals Agency (ECHA), as part of the activities of the European Union (EU) Observatory for Nanomaterials (EUON), is conducting a stakeholder survey on the substances available as nanomaterials in the EU market. The survey includes a market study of the nanomaterials, including substances, uses, volumes, and key operators in the EU. According to EUON’s May 21, 2021, news item, the survey aims to provide an overview of the substances that are available as nanomaterials on the EU market, as well as insight into their main areas of application and approximate volumes. Stakeholders are invited to complete a short questionnaire on the nanomaterial substances they produce, trade, or use. Respondents can also indicate their willingness and consent to participate in upcoming focus groups that are intended to provide a “realistic” projection of the growth of the nanomaterials market over the next five years.
