Pollution control technology wins Royal Society award

Nano-prorous fibres trap carbon dioxide and other pollutants so they can be removed and recycled back into the production process

A new technology that could drastically reduce the amount of pollution emitted by a range of industrial processes has received a prestigious award from the Royal Society.

The technology traps carbon dioxide (CO2) and other pollutants so they can be removed and, where possible, recycled back into the production process.

Although its first applications are most likely to be in the beverage industry, the technology could find uses in other areas, such as removing benzene from petrol vapour at filling stations.

The technology is made up of nano-porous fibres that have tiny pores less than 1,000th of the width of a human hair and contain materials which trap volatile hydrocarbons and other gases so they can be removed from the air flow.

Early trials of the technology have shown that it uses less than five per cent of the energy needed by the cleaning processes currently used in industry.

The £185,000 Brian Mercer Award for Innovation from the Royal Society will be used to help develop the technology to a stage where it has proven its commercial viability.

"It is great to have won such a prestigious award that will help us take this technology forward," said Dr Semali Perera, who developed the technology with research officer Chin Chih Tai in the University's Department of Chemical Engineering.

"The technologies currently used to clean process waste are usually energy hungry themselves, so our technology offers a great saving and could help to reduce the environmental impact even further."

Devices using the technology could be tailored to remove or recycle a diverse range of gases by varying the composition of fibres employed. Because the fibres can be 'spun' with a high surface area to volume ratio, these devices have superior efficiency and can be constructed in compact configurations making them suitable for applications in which space is a particular constraint.

"I have been very impressed by the support that RIS has provided both in helping to secure this award, and more generally in advising on the commercial direction for our research," said Dr Perera.

"Commercialisation of this technology would not have been possible without RIS's assistance in the filing the patent applications that cover our developments."

According to figures recently released by the Department for Environment, Food & Rural Affairs, net emissions of carbon dioxide in the UK were over 500 million tonnes in 2005. This represents about two per cent of the global man-made emissions.

"The technology could make an important contribution to cutting emissions of a range of different pollutants," said David Coleman, Technology Transfer Manager at the University of Bath who has been working on the commercial strategy for this technology.

"Although our initial thoughts have been geared towards the beverage industry, where recovery and reuse of CO2 could lead to significant operational savings, there are clear opportunities in a wide range of other different areas as well.

"The House of Commons Science & Technology Committee in 2005 stressed the importance of having zero-emission processing plants and encouraged greater deployment of CO2 capture, reuse and storage.

"This technology goes some way to achieving this, and we therefore believe that it could have a very exciting future."

The technology has also received significant industrial backing, in particular from Colin Billiet, the former CEO of domnick hunter group Plc. Colin Billiet is now working with the University on a new spin-out venture, 'nano-porous solutions Limited', in which it is intended that the novel technology will be developed further and commercialised.

"The technology developed by Dr Perera at the University of Bath offers fantastic potential, especially in environmental applications where CO2 and Volatile Organic Compound recovery are important areas for business development," said Mr Billiet, CEO for the new company.

"The novel nano-porous fibre technology provides for much lower energy consumption as well as providing solutions for which current technology is unsuitable.

"I am excited to be working with the University of Bath and with this new and innovative technology which has the potential to have a significant positive impact on the environment world-wide."

"We're delighted to be working with Colin Billiet," commented Dr Perera. "He has a vast amount of experience in this industry and has already contributed significantly to our commercial thinking."

The Brian Mercer Awards for Innovation were established by the Royal Society in 2001 as the result of a bequest received from the late Dr Brian Mercer. Dr Mercer was an enthusiastic inventor and entrepreneur and these awards aim to encourage these qualities in the next generation of scientists.

In 2005, Professor Julian Vincent from the Department of Mechanical Engineering at the University of Bath won a Brian Mercer Feasibility Award to help develop novel dehumidifier technology inspired by the desert cockroach.
