They are on the road, three in Ancona and one in Jesi, the four "smog-eating" buses of the Purifygo project, translated "Purify & Go", requested by Conerobus, the public transport company of Ancona and its province in collaboration with Ansaldo Trasporti. The buses are equipped with a filter system capable of stopping particulate matter with a diameter of less than 10 micrometers (PM10) and then collecting particles measuring PM2.5. Each bus covers a different type of public transport area, ranging from the city centre to the countryside. Each filter unit is capable of filtering 486,000 litres of air per hour. Assuming that each bus is in operation twelve hours a day, the filtering capacity of each system installed on the bus is 12 million litres of air per day per bus. Therefore, the four buses are able to filter a total of 4.2 billion litres of air during the three-month trial period. Once the experiment is over, indications can be obtained from the filters themselves on the degree of pollution in the areas covered. Comparing the different filters will allow the most effective materials to be chosen for the next industrial steps.
Real-time filter monitoringAnsaldo Trasporti, a company active in various branches of public transport, is collaborating on the project with the Italian company AGT Engineering, which runs the control centre in Rome, where the most important parameters of the system are monitored in real time. Particulate matter with a diameter of less than 10 micrometers and especially PM2.5 are increasingly linked to health problems such as asthma and lung cancer, and road traffic is one of the main causes of this type of pollution in urban areas. Ansaldo Trasporti is looking to the future of public transport with ever greener technologies. "Sustainability is an integral part of our corporate identity," said Gennaro di Sarno, CEO of Ansaldo Traporti, "our heritage is rooted in our determination to contribute to increasingly sustainable mobility through projects, investments and new partnerships. This project kicks off a new era of sustainable mobility, in which our company intends to play a leading role with projects and technologies that are increasingly geared towards safeguarding the environment".
