Italcementi announced on 25 May at the Milan congress of the Italian Federation of Scientific and Technical Associations that it had developed a special type of ecological cement that would allow large cities to tackle NOx emissions.
When in contact with sunlight, the product’s components release substances that will neutralise the polluting effects of nitrogen oxide. Levels of CO2 and SO2 are also expected to go down.
Designed to coat large urban surfaces such as roads, its developers have claimed that the new cement could cut pollution in a city like Milan by one-third. A 15 per cent coating of outdoor surface in Italy’s cities would cut pollution by 50 per cent, according to Italcementi experts.
