As you know, I built my artistic project “Lacer/actions” through the macro photographs of the decomposed and torn advertisings of the posters on the outdoor billboards. So, this is an interesting new: in an effort to contribute to improve the environment, the Guggenheim Museum Bilbao has decided to use a special coating in its outdoor advertising campaign materials that turns them into active air purifiers. This treatment is based on the natural process of photocathalysis, which causes a purifying effect similar to that of trees.
Thus, the large banner announcing the exhibitions on the Museum facade, the banners advertising the exhibition of artist Olafur Eliasson installed today in the lampposts along some of the main Bilbao streets, or the tram which will be entirely covered with advertising vinyl, will all be treated with Pureti® Print. Developed in collaboration with NASA and certified by different international laboratories, this technology is used by Estudios Durero during the production of the Museum’s graphic communication materials.
The present impact of these outdoor advertising campaigns could be equivalent to the air purifying effect of over 700 trees.
As Juan Ignacio Vidarte, Director General of the Museum, puts it: “a technology that allows us to help purify the air in our city was a great opportunity to go a step further in the Museum’s commitment to contribute, in all aspects possible, to stop climate change. Just as we are cutting down power consumption thanks to the change of the lighting systems in the Museum galleries, the possibility of purifying the air while acquainting our audiences with our art program was a great chance.”
A tested technology
The scientific basis of Pureti® Print is photocathalysis, a chemical reaction triggered by sunlight that turns oxygen and water vapor in the air into cleaning agents of pollutants such as NOx, SOx, or VOCs, as well as bacteria, mold, and bad odors. The benefits of this technology have been recognized by Tecnalia, a benchmark center in photocathalysis in Spain.
Pureti® Print is part of the European Project iSCAPE conceived to respond to the most important challenges that Europe will need to face in the future, with measures such as the development of actions to improve air quality and reduce pollution. Said project is part HORIZON 2020, the most important European Union Framework Program for Research and Innovation.




    1. Thank you so much Mr C! Yes, it is a positive new about Museum Guggenheim and Bilbao. It is an amazing Spanish city where art has the power to heal and to build a better urban life. I been there some years ago and I was really impressed by the City. Thank you and have a great day!

  1. Fantastic! I remember Bilbao and Guggenheim so well from my visit there in 2000. And of course all the Tapas Bars! Wonderful regenerated area.

    1. Yes Marysia, Bilbao is an example of urban regeneration, with more than 400 shops of all kinds. The city centre is an example of the best 20th century architecture, with buildings that have been housing the main institutions and companies in Bilbao for more than a hundred years. It is an outstanding architectural site, always designed by the best local architects.
