- Abstract:
- Nanomaterials (NMs) are typically regarded as materials that have one or more dimension of < 100 nm in size. Due to their extremely small size, nanomaterials exhibit properties that are vastly different from their 'bulk' chemical. These novel properties are therefore currently being exploited in a wide range of products, including pharmaceuticals, cosmetics, coating materials, electronic items and catalysts and a number of other applications are in the pipeline such as use, gene therapy, food packaging, advanced tyres, semiconductors and for use in bioremediation of contaminated environments. Nanotechnology is therefore a very rapidly growing sector of the material manufacturing industry that has already captured a multibillion market and by 2015 this market is forecast to be worth 2 trn Euro. As the nanotechnology sector increases in size, the amounts of NMs released to waste streams will increase and the types of NMs in waste are likely to become more diverse. Increases in NM concentrations in waste streams might affect the performance of some waste treatment methodologies or the acceptability of a waste product to an end user. As many waste products (e.g. animal manures and slurries, compost, sewage sludge and anaerobic digestate) are applied to the natural environment as fertilisers and soil conditioners, it is likely that emissions of NMs to the environment will increase and this could result in adverse impacts on organisms in the environment and on the services that the natural environment provides. Many of the NMs are produced using expensive, low yield production methods resulting in large volumes of waste and/or are made of rare elements where available resources are under threat of depletion. The development of approaches for recovery of NMs could offer a wide range of benefits in that they could begin to address the problem of resource depletion and would result in reduced emissions of NMs to soils and water bodies thus reducing potential impacts on the environment and the delivery of the associated ecosystem services. However, while a wealth of work is now being performed on the hazards of NMs to the environment and human health, limited work is being done on NMs in waste and on methods for recovery of NMs from waste streams. With the continued rapid growth of the nanotechnology sector, there is therefore a real need to understand the potential risks associated with NMs in different waste products to the environment and ecosystem service delivery and to develop recovery and other waste management approaches for controlling these risks. This catalyst project, involving leading experts in nanotechnology, green chemistry, bioremediation, environmental chemistry, ecotoxicology, ecology and environmental economics from the academic, business and government sectors, will therefore synthesise knowledge on the nature and amounts of NMs in waste streams in the 2020s, the potential impacts of these NMs on the health of the environment; and potential approaches for recovering NMs from different waste types. The project will involve a detailed review of the literature and expert interviews as well as an expert workshop. A stakeholder workshop will be staged to promote end user engagement in the project. The key outputs of the project will be a publication in a high impact journal and a highly innovative interdisciplinary proposal for submission to the second phase of the NERC funding programme.
