PolyU Project On Mitigation of Traffic-related Air Pollution Granted Green Tech Fund

The Green Tech Fund approved a HK$5.56 million grant to Prof LEE Shuncheng of the Department of Civil and Environmental Engineering at Hong Kong Polytechnic University (PolyU) to conduct research on the “Development of nanotechnology-based hybrid air cleaning system towards green transport.” The research aims at reducing multiple traffic related air pollutants in semi-confined Hong Kong's Public Transport Interchanges (PTI), without influencing traffic flow or modification of original infrastructures. This project develops a nanotechnology-based hybrid regenerable air cleaning system (RACS) by adapting advanced technologies such as active sampling system, green energy, novel air cleaning modules designed by the PolyU team. The as-designed RACS will be applied to remove traffic-related emissions of nitrogen oxides (NOx), fine suspended particulates (PM2.5), volatile organic compounds (VOC), and ozone (O3) in selected PTI in Hong Kong. The well-designed RACS is portable and could be tailored to various micro urban environments. It will first conduct field test at selected PTI in Hong Kong, and then expand for potential application in areas with dense traffic emissions such as closed street canyons, train stations, runways, customs ports, car parks, taxi stands, tunnel, airport, etc. The expected deliverables of this 24-months project will enable efficient mitigation of traffic-related air pollution, supporting the Hong Kong Government to realise green transportation and create a more liveable environment under the Hong Kong Clean Air Plan 2035. Green Tech Fund (GTF) The Government set up the Green Tech Fund (GTF) in 2020 to fund research and development (R&D) projects which help Hong Kong decarbonise and enhance environmental protection. The assessment committee is chaired by the Director of Environmental Protection and comprises members from academia, industry and green groups.

PolyU researchers compile world’s first “atlas” of airborne microbes that provides an important new perspective for public health research

Bacteria are truly abundant across the Earth’s surface, from the soil to the oceans. The microbial population of the air that surrounds us is comparatively unknown, but a research expedition led by PolyU scientists is about to change that. After nearly a decade of effort, they have compiled a comprehensive map of the world’s airborne microbes, providing fresh insights into how these species interact with the surface environment – as well as their likely future changes. A cubic metre of “empty” air contains 10,000 bacteria or more, and interest in the role of air as a habitat – not merely a conduit – for microbes has grown enormously since the start of the COVID-19 pandemic. In collaboration with researchers on the mainland and the US, the PolyU-led team spent around a year sampling airborne microbes across the world, from ground level to mountaintops. Combining their own results with the most accurate global data collected in past studies, they and their research partners compiled the first ever atlas of the global airborne microbiome. The atlas provides a wealth of insights into the microbial communities floating above the ground. There is no doubt that the air is a unique harbour of bacterial life. Genetic analysis by the team showed that the core communities – the handful of species that form an outsized proportion of the microbe population – were not the same in the air as those in marine or soil ecosystems. In fact, even though the air is a free-flowing medium with seemingly no internal boundaries, these core bacterial communities are distinctly localised and stable. The research team analysed the bacterial communities of 370 individual air particulate samples collected from 63 sites around the world, ranging from those at ground level (1.5 – 2 m high) to rooftops (5 – 25 m high) and high mountains (5,238 m asl), as well as from densely populated urban centres to the Arctic Circle, for a more diverse coverage in terms of altitudes and geographic regions. Prof. Xiang-dong LI, Chair Professor of Environmental Science and Technology and Dean of Faculty of Construction and Environment of PolyU who led the research team, said, “We have verified that human activities have certainly changed the structure of microbiomes in the natural ambient air, particularly with a higher abundance of pathogenic bacteria in urban air. Having experienced the pandemic for three years, people now pay more attention to this invisible but influential microbial community. The research outcomes could be served as a critical reference for predicting planetary microbiome responses and the health impacts of inhalable microbiomes with future environmental changes.” The researchers estimate that the total number of microbes occupying the sea or soil is thousands of times larger than those in the air. Nonetheless, the aerial diversity of microbes – known as “richness” – is just as high. This suggests that surface habitats directly contribute microbes to the air. Overturning previous assumptions, vegetation is not the main terrestrial source of airborne bacteria, and the Earth’s vast tracts of soil provide very small fraction. The crashing of waves, the shaking of leaves, and even frequent activities and constant respiration of animals and humans are bigger drivers of bacterial exchange between the surface and the air. Macroscopic life, notably animals and plants, is most diverse in equatorial regions (consider, for example, warm and wet rainforests), and its diversity decreases closer to the poles. For microbes, the picture is more interesting – moving from the equator, diversity maximises at mid-latitudes before falling away again. This pattern was well established for terrestrial and aquatic microorganisms, but the new atlas confirms that it applies to the airborne microbiome, too. The authors surmise that the “bump” in diversity at mid-latitudes is caused by stronger sources of microbial input to those regions. Overall, the researchers estimate that half of airborne bacteria originate from ground sources. Urban air has especially high rates of human-associated bacteria – some harmless, others pathogenic. Direct transfer of germs from people to air is not our only effect on the airborne microbial world. Broad-scale activities such as industrialisation disrupt natural environments and impact air quality. This weakens the environment’s “filter” effect on microbial structure, making the composition of airborne bacteria more affected by random processes – although weather still plays an important role too. The close relationship between modern human activities and the microbes around us underscores the need to predict future changes accurately. The inhalable infectious bacteria that proliferate in cities are particularly of concern considering rapid urbanisation and our growing understanding of airborne contagion, spurred by COVID-19 research. Climate change is another impetus, given the marked effect of temperature on microbial richness, as revealed by the atlas. Hence, the study provides an invaluable resource and an important new perspective for future public health research. The PolyU team collaborated with Prof. James M. TIEDJE, University Distinguished Professor at Michigan State University and scientists from mainland China in the study. The findings were published in the Proceedings of the National Academy of Sciences (https://www.pnas.org/doi/full/10.1073/pnas.2204465119), a peer-reviewed journal of the USA National Academy of Sciences.

The collaboration echoes President Xi Jinping’s earlier call for Hong Kong to ‘strengthen the collaborative development of enterprises, universities and research institutions, and to develop into a global scientific and technological innovation hub’. SHKP and PolyU will join hands on three research projects: green application: developing a smart, efficient and flexible energy management system; green building materials; and green construction processes. The teams will explore how to translate research into applications to help Hong Kong develop into a smart and carbon-neutral city. SHKP will also launch the SHKP x PolyU Building Homes with Heart Scholarship Programme to support 56 outstanding students to pursue studies in construction, real estate and engineering-related disciplines at PolyU. The signing ceremony was witnessed by Paul Chan, Financial Secretary of the HKSAR; Zhang Zhihua, Director General of the Youth Department of the Liaison Office of the Central People's Government in the HKSAR; Dr. Lam Tai-fai, PolyU Council Chairman; Professor Wong Wing-tak, PolyU Acting President; Raymond Kwok, SHKP Chairman and Managing Director; and Adam Kwok, SHKP Executive Director. The MoU on SHKP x PolyU Building Innovation & Technology Research Projects was signed by Eric Tung, SHKP Executive Director, and Professor Christopher Chao, PolyU Vice President (Research and Innovation). Eric Tung also signed the MoU for the SHKP x PolyU Building Homes with Heart Scholarship Programme with Professor Ben Young, PolyU Vice President (Student and Global Affairs). Details of the research projects and the scholarship programme are at Annex. Guest of honour Financial Secretary Paul Chan said: “We expect the construction volume in Hong Kong will increase to about HK$300,000 million per year. Such a huge volume of projects will provide exceptional development opportunities for the construction industry. Nevertheless, the industry will also face various challenges and need to find ways to, for example, deal with labour shortages, have a better control of construction costs, optimize the management process, further improve construction safety and reduce carbon emissions to contribute to society as a whole. Innovation and technology is a key to addressing these challenges. The application of academic research outcomes will allow the construction industry to increase their use of innovative technologies, which would be of enormous benefit.” SHKP Chairman and Managing Director Raymond Kwok noted that the Report to the 20th National Congress of the Communist Party of China highlighted the importance of ‘talent as our primary resource, and innovation as our primary driver of growth’. Recently when Chief Executive John Lee delivered his Policy Address, he also clearly pointed out that innovation and technology (I&T) will be a key impetus for Hong Kong's high-quality economic development, and that it is essential to commercialize research results through collaboration between the industry, academic and research sectors. Raymond Kwok said: “We hope to leverage PolyU’s strengths in academic research and our extensive practical experience to promote innovation and technology research in the construction industry. The National 14th Five-Year Plan laid out plans to achieve ‘peak carbon and carbon neutrality’. Our initiative will help Hong Kong become a green, low-carbon international I&T hub.” He added that SHKP also places great emphasis on talent development, and that it is important to remember that ‘Hong Kong will prosper only if its young people thrive; that Hong Kong will develop only if its young people achieve well-rounded development; and that Hong Kong will have a bright future only if its young people have good career prospects’. The SHKP x PolyU Building Homes with Heart Scholarship Programme aims to support promising PolyU students with limited means to study construction, real estate and engineering-related disciplines. He hailed PolyU as a cradle for cultivating talent for Hong Kong’s construction industry, adding its graduates have contributed a lot to the development of both the industry and the city. He noted a number of PolyU graduates have joined SHKP and supported the development of its premium properties and hoped PolyU students will continue to help advance the development of building technologies. PolyU Acting President Wong Wing-tak said: “PolyU attaches great importance to transforming research into practical applications. We are delighted to collaborate with Sun Hung Kai Properties, one of the largest property developers in Hong Kong, to leverage their experience in developing high-quality property projects. By combining PolyU’s outstanding scientific research achievements in developing innovative technologies including smart energy systems, green building materials, decentralized construction process, etc. with Sun Kung Kai Properties’ expertise, we strive to achieve the three goals of carbon reduction, energy savings and digitalization to reduce emissions and improve efficiency on SHKP’s buildings.” Professor Wong expressed his thanks to SHKP-Kwoks’ Foundation for its support to PolyU in setting up a scholarship scheme to help outstanding students with financial difficulties, and believed that this collaboration will not only promote the advancement of new green technologies, but also nurture a new generation of talents who will benefit the entire industry, helping Hong Kong to become carbon neutral and creating a sustainable future for wider society.” SHKP Executive Director Adam Kwok said: “SHKP and PolyU joined hands in 2005 to optimize the energy-saving performance of ICC through the use of green and smart building technology, which proved to be a great success. Not only has ICC obtained a number of international green building certifications, its LEED (Leadership in Energy and Environmental Design) platinum score, awarded by the US Green Building Council, is also the highest among commercial buildings in Hong Kong. SHKP is delighted to partner with PolyU again to translate the outcomes of their scientific research into applications, using green applications, green materials and green processes to help Hong Kong achieve net zero and develop into a world-class smart city. The smart energy management system in the Group’s High Speed Rail West Kowloon Terminus Development alone is estimated to be able to reduce 3.6m kg carbon emissions each year, which is equivalent to planting 160,000 trees. SHKP is keen to play a key role in Hong Kong’s transformation, realization and commercialization of building technology research outcomes, and in the nurture of young talent.”
