The refurbishment of a significant part of the flight infrastructure of the Sardinian airport was carried out by Gruppo Vitali Spa, a leading group in the field of large-scale infrastructures for mobility and real estate development, with a specific focus on economic circularity and the re-use of processing materials.
The operations concerned the extraordinary maintenance of the northern perimeter road of internal connection; the extraordinary maintenance of the Mike junction with adjustment of the width and lift of the road and the refurbishment of the entire center line. In detail, about 13,000 square meters of flooring have been restored, no longer performing. Road signs have also been restored; guard rail elements and vertical signs have been replaced and integrated. The work on the Mike connection covered a total area of about 60,000 square meters.
The activity in this case was necessary to modulate its portance, in anticipation of a reuse in the future. The existing flexible flooring has been completely redone, with a new underlay package that guarantees higher performance; a new LED lighting system has also been implemented. Started in December 2020, the work has been completed according to schedule. But what most marked the operations was the focus on economic circularity. According to the paper “The circular economy: an opportunity to rethink construction” written by the Ministry of Economic Development, In fact, in Italy the construction sector produces about 60 million tons of waste every year and almost 90% of this escapes from the recycling chain. Vitali, with the airport of Cagliari demonstrates how it is possible – as well as absolutely necessary – to introduce sustainable behaviour also in the construction sector.
By installing the mobile plant of Euromecc, Vitali has processed, recovered and reused directly on site, the secondary raw materials resulting from the operations carried out on the track. The resulting materials from excavations and demolitions have been adequately treated and reused.” In this the materials have found new life thanks to the specific processing plants that have allowed their reuse with consequent saving of virgin material as well as decreased traffic of means for the transport of said materials, resulting in savings in terms of CO2 emitted.
The recovery of scrapped materials through processing with specific plants also positioned within the site has allowed to achieve multiple results: • Avoided use of virgin materials and excavation;
– Zero traffic of vehicles to and from the airport for these materials, resulting in savings in terms of CO2 emitted;
– More flexible management of materials produced;
– Improved economic performance. Tangible results 100,000 cubic metres of materials entirely reused It is the size of a small quarry.
With this intervention, the excavation of virgin material was avoided. 6,000 trips less Thanks to the solutions adopted were avoided more than 6,000 vehicles in transit from and to the airport. LED lighting The new ALVs will ensure considerable savings in terms of consumption over the next few years.
