It seems not to be that bad in Europe, but when you start to dig into the data \u2013 especially (when you look at) fine and ultrafine particles, some of them are not even visible but they have a detrimental effect to the health.\u2019<\/p>\n<p class=\"selectionShareable\">According to the World Health Organization, air pollution currently poses the biggest environmental risk to human health.<\/p>\n<p class=\"selectionShareable\">\u2018The fact is that locally some pretty high levels have been recorded in Europe, which means that there is a need to clean up the air,\u2019 said Theron.<\/p>\n<figure id=\"attachment_531\" aria-describedby=\"caption-attachment-531\" style=\"width: 1687px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/scienceblog.com\/wp-content\/uploads\/sites\/4\/2018\/10\/theron.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-531\" src=\"https:\/\/scienceblog.com\/wp-content\/uploads\/sites\/4\/2018\/10\/theron.jpg\" alt=\"Jean-Jacques Theron says that an outdoor air filter needs to be able to deal with a wide variety of particles.

Image credit &#8211; EU<\/figcaption><\/figure>\n<\/div>\n<p class=\"selectionShareable\">To tackle the problem, Theron\u2019s team decided to adapt a filter designed to capture vehicle emissions so that it could clean the air of particulates. In line with the prize criteria, they had to ensure that it was sustainable, compatible with the environment and affordable.<\/p>\n<p class=\"selectionShareable\">\u2018We adapted and developed the filter concept which was initially invented at Corning for mobile emissions. The main challenge here, and one of the reasons why we could not just stick it outside, is the large diversity of particles for outdoor applications &#8211; dust, fly ash, smoke, aerosols, fumes, mist and condensing vapours &#8211; versus the ones from mobile emissions &#8211; soot particles from internal combustion engine emissions,\u2019 said Theron.<\/p>\n<p class=\"selectionShareable\"><strong>Honeycomb<\/strong><\/p>\n<p class=\"selectionShareable\">The key to the filter is the honeycomb design and ceramic materials. As air passes through the structure, particulate matter sticks to the walls, leaving clean air to be expelled.<\/p>\n<p class=\"selectionShareable\">\u2018The honeycomb structure is geared to obtain a very large filtration area over a very small space,\u2019 said Theron. \u2018And the ceramics are important firstly because we have the opportunity to manipulate them into honeycomb structures and secondly because the ceramic is porous, which enables it to capture the finer particles.\u2019<\/p>\n<p class=\"selectionShareable\">The material that forms the filter is called cordierite \u2013 it\u2019s made from a blend of clay, alumina, talc and silica. \u2018These are all-natural inorganic materials,\u2019 Theron said. Cordierite has a high melting point, which makes it very durable.<\/p>\n<figure id=\"attachment_532\" aria-describedby=\"caption-attachment-532\" style=\"width: 1790px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/scienceblog.com\/wp-content\/uploads\/sites\/4\/2018\/10\/system-crop.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-532\" src=\"https:\/\/scienceblog.com\/wp-content\/uploads\/sites\/4\/2018\/10\/system-crop.jpg\" alt=\"The ceramic filters have been tested in a prototype system but the final design of a full-size filtration station is still being worked out.

Image credit &#8211; Corning Incorporated<\/figcaption><\/figure>\n<\/div>\n<p class=\"selectionShareable\">The combination of material and design leads to a highly effective filtration system. The design of the final system is still being finalised, but a full-size unit could be around 10 metres tall and deliver 3.6 million cubic metres of purified air every day.<\/p>\n<p class=\"selectionShareable\">The researchers will use some of their prize money to work out how many units would be needed to ensure clean air in a given area, and the stations will be designed to adapt to various pollution levels so the strength of the filtration process can be adjusted.<\/p>\n<p class=\"selectionShareable\">In collaboration with the team in China, Theron\u2019s lab placed prototype filter stations in Shanghai, China and north of Paris, France, and monitored their performance. They found that it helped to keep the level of particulates smaller than 2.5 microns below the World Health Organization threshold for clean air of\u00a0<a href=\"https:\/\/ec.europa.eu\/eurostat\/web\/products-datasets\/-\/T2020_RN210\" target=\"_blank\" rel=\"noopener noreferrer\">10 micrograms per cubic metre<\/a>.<\/p>\n<blockquote>\n<p class=\"selectionShareable\">&#8216;Some pretty high levels have been recorded in Europe, which means that there is a need to clean up the air.&#8217;<\/p>\n<p class=\"selectionShareable\">Jean-Jacques Theron, Materials Director, Corning European Technology Center<\/p>\n<\/blockquote>\n<p class=\"selectionShareable\">The stations also collect air pollution data on a daily basis, providing a high-quality dataset that will allow the scientists to track pollution levels over time and make adjustments to the filtration strength levels as necessary.<\/p>\n<p class=\"selectionShareable\">The technology is still in the prototype phase, but the money from the Horizon Prize will go towards getting it onto the market, hopefully in time for the 2024 Olympic Games in Paris. Theron envisages that the filters will be officially launched at the Olympics, and the stations could be placed in the Olympic Village, with the goal of providing the athletes with a source of high-quality purified air.<\/p>\n<p class=\"selectionShareable\"><i>Originally published on <a href=\"https:\/\/horizon-magazine.eu\">Horizon<\/a><\/i><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>A new type of outdoor filter that could cut city air pollution and is scheduled to be debuted at the 2024 Paris Olympics has been awarded the \u20ac3 million\u00a0Horizon Prize on materials for clean air.
