According to the World Health Organisation (WHO), a staggering 99 per cent of the global population breathes air that exceeds WHO air quality limits and threatens people’s health. More than 6,000 cities across the globe are now monitoring air quality, but the people living in them are still breathing unhealthy levels of fine particulate matter and nitrogen dioxide, with people in low and middle-income countries suffering the highest exposures.   In Europe alone, air pollution kills more than 1,200 children and teenagers per year, according to a report released by the European Environment Agency (EEA). It also significantly increases the risk of disease later in life. Meanwhile, 78 out the 100 most polluted cities in Europe are located in the emerging Europe region, according to IQAir.  Shajjad Rizvi MBE, the CEO of Hungarian start-up Resysten, speaks with Andrew Wrobel about Clean Air, his company’s solution. It utilises advanced binding technology and the principles of titanium dioxide and sunlight, which purifies the air through photocatalysis eliminating harmful pollutants associated with various health conditions.  They also talk about the challenges of communicating innovative solutions to potential buyers and how businesses can offset their carbon footprint by cleaning their air.
