The ultrafine particles emitted by cars and trains impair the air quality in many cities. Braking also releases ultrafine particles into the environment. Measuring no more than a virus in size, they penetrate human tissue and are damaging to health. In the podcast, Christophe Rocca-Serra, founder and CEO of Tallano Technologie, talks about the braking system he has designed which reduces particle emissions by 90 per cent. These are vacuumed directly at source from the brake shoes to ensure they cannot disperse into the environment. In addition to the podcast, other InnoTrans media releases are also highlighting rail technology and mobility innovations. InnoTrans director Kerstin Schulz will present the InnoTrans Report – a B2B trade magazine – and the InnoTrans Daily newsletter.
