The European Union-funded NanoSustain project is investigating four different products containing nanomaterials in an effort to answer end-of-life questions – can they be recycled, or can they be safely disposed of? – regarding such products. The four nanomaterials are: carbon nanotube epoxy resins (plastics for structural or electrical/anti-static applications); titanium dioxide (for paints); zinc oxide (for glazing products); and, nanocellulose (for advanced paper applications). Last week, a public dissemination event was held in Glasgow, United Kingdom, by the NanoSustain partners. Preliminary results were presented, including: the physical and chemical characterization of the dust particles from sanding painted boards; physiological responses to these particles; incineration of ground glass; and composting of nanocellulose papers. The partners reported that one of the main difficulties is that research results are often based on quite different starting materials, making comparisons difficult. The partners have created a database of research literature on the chosen materials, for use by the partners and members of the EU’s cluster on nanosafety research. The NanoSustain consortium has two years remaining in the project, and a second public dissemination event is planned for spring 2012.
