Enabling Safe Air Quality Levels In The Transport Industry With Game-Changing Air Filtration

点击翻译按钮获取中文摘要

The transport industry has been significantly impacted by the Covid-19 pandemic. People fear that virus-containing bioaerosols cause infection on board which has contributed to the spread of the pandemic. This is also compounded by reports of air-quality issues arising from the often-unpleasant odorous volatile organic compounds (VOCs) and airborne particles. This problem is global, affecting all types of transport including airplanes, trains, buses, cars and even passenger ships. Air quality could be greatly improved by introducing filters that not only kill viruses but also capture VOCs and odours, thereby reducing risks of infection and health concerns while boosting the confidence of passengers and crew in post-pandemic travel. Unfortunately, existing air-filtration technologies are unable to deliver the performance required even when used in combination (i.e. HEPA with charcoal filters). Therefore, alternative and novel solutions are required.Aqdot (a Cambridge-based SME) has a unique, proprietary VOC/malodour-capture technology (AqFresh) that is effective against a wide range of molecules that are unpleasant and/or harmful. The innovation is currently commercially available in home care, pet care and industrial cleaning products. This project aims to adapt the technology to meet the needs of the transport industry by developing scalable, ready-to-adopt air filters that bring together novel VOC/odour capture technology with antiviral capabilities, significantly improving air safety and quality in transport.The innovative filters, generated by impregnating appropriate polyurethane foam substrates with a unique coating formulation, will be designed to fit into existing systems of global filter manufacturers. The filters will be formulated and tested for anti-viral and VOC-reduction capabilities. These filter prototypes will then be incorporated and tested in operational environments by commercial manufacturers with a view for global roll out. Aqdot will partner with customers to allow rapid adoption of this innovation in their filtration frameworks in aerospace, automotive and public transport.Upon success, Aqdot's innovative air filters will bring major improvements in air quality for the transport industry worldwide to be free from viruses, VOCs and odours, minimising the risk of infections and health concerns onboard, helping to combat the immediate Covid-19 pandemic while reducing the impact of future potential pandemics. It will also assure safety and build confidence among passengers and crew to resume travelling following the pandemic, reinvigorating the transport industry and giving a much-needed boost to the economy. The project will demonstrate support for innovative UK-based SMEs, strengthen the UK technology portfolio and has significant export potential.After successful demonstration of the technical feasibility and potential of the innovative filtration technology combining VOCs/malodour capture and antiviral performance, the extension for impact will focus on speeding the market uptake of the technology. Key partners will be engaged in collaboration programs to assess the filters performance under operational conditions. A clear and detailed commercialization strategy will be put in place as well as key engagements will be established for definition of the supply chain for large scale production of the materials. In overall, the new filters will be ready for market adoption in a suitable format for large scale production and their market potential will be realised, strengthening the UK technology portfolio, minimizing the impact of Covid-19 and delivering extra benefits to society.
