Turin is one of the most polluted cities in Europe, with an annual average of 39 micrograms per cubic meter. The idea of the project is to repurpose the soil excavated from the construction of the 57 km railway tunnel that will connect Turin to Lyon in order to mitigate the city's pollution
Sponge Mountain in Turin. Artificial mountain absorbs air pollution
Sponge Mountain is architect Angelo Renna's project for an artificial mountain which, by re-using soil excavated from the construction of the Turin-Lyon high-speed railway would be able to absorb the city's pollution
This is an incredible amount of waste that can be used in an intelligent way, as quarry soil has a better capacity to sequester CO2. The mountain measuring 90 metres high and spread over 11 hectares, is capable of capturing CO2 from the atmosphere thanks to its engineered soil: a mixture of sand, cement and other types of terrain
In addition, the 'sponge mountain' could be a green landmark in the city and a place where people can go for a walk or a run. A large number of researchers took part in the project, called the Success Project, in order to better capture carbon and support the biodiversity of the ecosystem
