From environmental problem to possible raw material. Etna’s volcanic ash, which covers roads, roofs and agricultural fields in eastern Sicily after every eruption, could soon change status: no longer a special waste to be disposed of, but a resource to be reused in different production cycles. This is the change of perspective at the center of the technical-scientific conference “Sustainable reuse of volcanic ash from Etna,” scheduled today at the Regional Palace in Catania.
The initiative is promoted by the Water and Waste Department of the Regional Department of Energy and Public Utilities and the Department of Civil Engineering and Architecture of the University of Catania. The goal is to bring together institutions, universities, research organizations and companies on how to enhance a material that has always accompanied the life of Etna’s territories but has so far been treated almost exclusively as a cost to be managed.
The new decree
During Etna eruptions, in fact, volcanic ash can quickly accumulate in built-up areas. Municipalities are forced to organize collection and disposal operations that involve substantial expenses and complex procedures. Instead, the idea behind the new regional approach is to transform this natural material into an economic and industrial resource.
The turning point is represented by Implementation Decree No. 8 of Feb. 22, 2024, issued by the Water and Waste Department of the Sicilian Region, which introduces guidelines for the recovery and reuse of volcanic ash within various production processes. The measure aims to define standards and procedures to encourage the recycling and use of lava material, while reducing the burden on local governments.
According to Regional President Renato Schifani, the project is an example of innovation applied to natural resource management. The benefit is twofold: on the one hand easing costs and procedures for municipalities called to clean up the cities after the so-called “ash rains,” and on the other hand incentivizing companies to use volcanic material as a new raw material.
The potential
There is no shortage of potential. Scientific studies conducted in recent years have shown that Etna ash can find application in a variety of sectors, from construction to the production of infrastructure materials, to agriculture and the creation of innovative mineral-based products. A use that would reduce the consumption of traditional raw materials and make the most of a resource available in large quantities in the area.
The Catania conference will consist of two working sessions throughout the day.
For the promoters of the initiative, this is an important step to initiate a more modern and sustainable management of a natural phenomenon that is part of the identity of the Etnean territory. In fact, transforming volcanic ash from waste into a resource means placing it in a circular economy logic, reducing public costs while creating new opportunities for the local production system.
It is an approach that also fits in with Europe’s Green Deal strategies, which aim to reduce material waste and enhance the reuse of available resources. In this case, the raw material comes directly from Europe’s most active volcano. And what until now was considered only an emergency to be managed could become, at least in part, a new development opportunity.
