Volatile organic compounds (VOCs) are carbon-based compounds, many of which are hazardous to humans' health. EU-funded researchers coordinated efforts to apply nanotechnology to the capture and sequestration of these compounds.<\/p>\n
VOCs evaporate into the air at room temperature. The evaporation process produces tiny air-borne molecules that may be unsafe to those who inhale them, come into contact with them via skin, or drink them in contaminated water supplies. <\/p>\n
While the use of VOCs has been restricted in recent years, there are still thousands of products present in everyday life that contain VOCs. Removal of VOCs from waste air streams, whether at factories that use VOCs or at wastewater treatment plants that remove VOCs from wastewater, is commonly accomplished with separation membranes. <\/p>\n
The application of nanotechnology (technology on the scale of atoms or molecules) to membrane filtration of VOCs in waste air streams may greatly enhance functionality. <\/p>\n
Nanoparticles have the unique feature of having very high surface areas compared to their volumes. This surface area is extremely useful as a work surface for chemical reactions and absorption of other molecules. <\/p>\n
However, integration of nanotechnology with membrane separation technology for more efficient and greener removal of VOCs from waste air streams is an emerging, developing field. <\/p>\n
In order to coordinate efforts in research with those in industry and in policymaking bodies, European researchers initiated the ANVOC project. <\/p>\n
The main goal of the project was to organise a symposium bringing together stakeholders from all areas to disseminate knowledge to end users and to facilitate cooperation among research and development (R&D) bodies. <\/p>\n
ANVOC scientists met all goals, bringing together international experts in nanotechnology, membrane technology and air pollution control. <\/p>\n
The symposium presented R&D results, identified the types of membranes used in recovery of VOCs, and demonstrated the use of membranes in gas separation. In addition, valuable possibilities for future research collaboration were identified. <\/p>\n<\/p>\n
