One of the great problems of the environment and the protection of the community’s well-being is air pollution in urban areas. Pollutants are normally generated from traffic, heating and industrial production that accumulate in the lower parts of the atmosphere, in the absence of wind or precipitation. Until now, people have tried to fight this phenomenon passively, reducing the hours of heating and limiting traffic use. In large cities, pollution could be significantly reduced.

In fact, it is possible to clean the air of urban centres by using innovative cement materials made from “self-cleaning” ecological photocatalytic cement, in the refurbishment of roads and squares, the construction of infrastructure, the construction of buildings and the renovation of houses. This exceptional result is offered by “cement photocatalysis”, especially by the new eco.city product line which uses the TVActive technology of the Italcementi S.p.a group.
