Tittel

Investigating the fate of nanomaterials in waste water treatment plants; removal, release and subsequent impacts

Populærvitenskapelig sammendrag

The quantity of man-made nanomaterials (MNMs) being used in consumer products continues to increase. Some consumer products such as sunscreens and cosmetics directly expose humans and the environment to MNMs. However, potential concerns regarding the safety of nanomaterials to humans and the environment, have led to many technology applications actively 'locking away' MNMs during the lifetime of consumer products. Importantly, during or at the end of their life, most consumer products will enter a waste processing facility, e.g. WWTP or solid waste processing plant and MNMs will potentially be released. The NanoWASTE project seeks to fill existing knowledge gaps on MNMs 'end of life' and answer key questions for scientists and regulatory authorities.

 

The NanoWASTE project will investigate what happens to MNMs when they enter WWTPs. The NanoWASTE project will specifically study titanium dioxide (TiO2) and silver (Ag) MNMs as they are already widely used in a number of consumer products and found to enter waste water streams. In order to be able to follow the TiO2 and Ag MNMs in a complex WWTP system isotopically labelled versions will be synthesised and used in the project. One part of the work will study how the WWTP processes and conditions affect the physical and chemical properties of MNMs (e.g. size, aggregation, surface chemistry) through 'aging'. Importantly, the project will assess MNM removal efficiency during the waste water treatment process. A second focus is to see if there are any negative effects from MNMs which cause a decrease in the operational efficiency of WWTPs. MNMs entering WWTPs will either be removed from the water stream into the sewage sludge or pass directly through the system, exiting with the water effluent. Sewage sludge is often used further as an agricultural fertiliser whilst waste water effluent is typically discharged directly to aquatic systems. The environmental impacts of 'aged' MNMs in both waste water effluent and sewage sludge will be studied, including a comparison with pristine MNMs. In the final stage of the project, models for predicting MNM fate in WWTP processes will be developed

 

Overall, the project will provide a greater insight into the potential hazards of MNMs to both WWTPs and the environment. The project aims to challenge nanotechnology developers to consider 'end of life' as a key aspect of their design approach. The data generated in this project will be presented to stakeholders together with suggestions for protecting WWTPs from MNM impacts and for reducing MNM release from WWTPs. We hope that the knowledge generated can contribute to the development of future regulations regarding MNMs in consumer products and their disposal at 'end of life'.

Vitenskapelig sammendrag

The NanoWASTE project will investigate the fate of manufactured nanomaterials (MNMs) in waste water treatment plants (WWTP), impacts of MNMs on WWTP processes and the subsequent environmental impacts of MNMs in waste effluent. Traceable doped MNM test materials will be used to investigate the direct impact of MNMs on physical, chemical and biological WWTP processes and the ecotoxicity of 'aged' MNMs present in waste water effluent and sewage sludge. Overall, the project will provide a greater insight into the potential hazards of MNMs to both the WWTP and the environment. Understanding how MNMs behave, change and are removed in a WWTP will help develop relevant preventive measures to limit the release of MNMs during their production, use (e.g. in consumer products) and application in end-products or as components in other products or processes.

The project will challenge technology developers to consider 'end of life' as a key aspect of their approach at all life stages; production (industrial waste), use (discharge into waste systems) and waste/recycling. This project will include mapping of MNM sources leading into the WWTP and the development of models for predicting MNM fate in WWTP processes. Furthermore, the project will specifically develop new methodologies for characterising MNMs in WWTPs and how they are transformed (aged) during the process. Finally, the project will investigate the ecotoxicity of both pristine and 'aged' MNMs from WWTP water and sludge effluents in relevant environmental compartments. Importantly, the data generated in this project will be presented to stakeholders together with suggestions for protecting WWTPs from MNM impacts and proposals for reducing MNM release from WWTPs. We believe that the knowledge generated about MNMs in WWTPs can serve as a basis for development of future regulations regarding MNMs in consumer products and their disposal at 'end of life'.

 

Aim

To understand and model the fate and impact of manufactured nanomaterials (MNMs) through wastewater treatment plants (WWTPs) and their subsequent potential for environmental effects

 

Objectives

  • Use state of the art characterisation approaches to determine how the physciochemical characteristics of MNMs transform (‘age’) through laboratory scale WWTP processes

  • Determine the removal of MNMs in WWTP streams and quantify them in waste water and sludge effluents

  • Map MNM uses expected to lead into the WWTP and develop models for predicting MNM fate in WWTP processes.

  • Investigate the direct impacts of MNMs on WWTP microbial communities and emissions

  • Compare the ecotoxicity of pristine MNMs and MNMs ‘aged’ in the WWTP process in aquatic and terrestrial environments

  • Conduct validation field trials using samples collected from full scale WWTPs in Norway
