Finishing the second phase of application of EQUINOX project in Madrid (Spain)

16 june 2017

The consortium of LIFE EQUINOX project has working this week on the Madrid’s streets in the second phase of application of photocatalysis treatment on asphalt paving, whose aim is the elimination of Nitrogen Oxide (NOX) in the urban environments. The final goal of this project, led by CARTIF, is improving of air quality in cities throughout the development of these ‘new anti-polluting roads’.

The elimination of Nitrogen Oxide is got applying the heterogeneous photocatalysis, that uses a photocatalyst (Titanium dioxide TiO2) and solar radiation. The treatment is applied in order to evaluate the capacity of eliminate the contaminants originating from the traffic. In this second phase, the goal is to know the results when the treatment is applied on newly extended pavement and in mixtures with high level of voids. For these reasons, the streets of Alberto Aguilera, Carranza and the roundabout of Ruiz Jiménez, all of them in Madrid, have been choosen.

In the first phase, carried out in the summer of 2016, the treatment was applied in the streets of Bravo Murillo, Fuencarral, Carranza, Alberto Aguilera, Blasco de Garay, Galileo, Vallehermoso, Cea Bermúdez, Fernández de los Ríos, Fernando el Católico, Arapiles, Quevedo y Ruiz Jiménez. In these places, levels of air quality are being analysed since last summer.

The consortium of EQUINOX is integrated by Madrid City Council, ELSAN, REPSOL and CARTIF.
