An environmental problem, a technological solution that draws on the past: recovering the ashes to use them in an economy of value as fertilizers or detergents.
Now, the ashes and lapilli specifically are volcanic ones, resulting from the eruptions of lava and which, remaining on the ground, have a strong negative value in terms of pollution. with tons of volcanic ash and lapilli.

The Reucet project (Recovery and use of Etnean volcanic ash) has studied the possibility of transforming them into civil and environmental engineering solutions. Concrete, mortars, plasters, traditional brick products for road foundations, for geotechnical works, up to solutions in which it is used as an absorbent with the aim of reducing pollution.
Paolo Roccaro, full professor of Environmental Health Engineering of the Department of Civil Engineering and Architecture (Dicar) at the University of Catania, is the manager of the project, financed by the Ministry of the Environment with 71 thousand euros.
The issue was addressed with an interdisciplinary approach which involved various research groups coordinated by Salvatore Damiano Cafiso, Loredana Contrafatto, Ernesto Motta and Federico Vagliasindi del Dicar, Antonino Pezzino and Marco Viccaro from the Department of Biological, Geological and Environmental Sciences and Enrico Ciliberto from the Department of Chemical Sciences.
