Directa Plus PLC (LON:DCTA) has noted the opening on Monday, August 4 of the new Genoa San Giorgio Bridge in Genoa which was constructed using Iterchimica's Gipave asphalt supermodifier for its road pavement, which contains graphene and a specific type of technically-selected plastic which is usually sent to waste-to-energy plants.
The new bridge, replacing the old Morandi Bridge structure that collapsed on August 14, 2018, was completed just 22 months after the disaster to designs by Genoa born Renzo Piano.

Gipave was developed by Iterchimica with the support of Directa Plus and resulted from a three-year research programme with a patent filed in 2017. To date, two trials have been initiated or completed in the UK in Oxfordshire and Kent and seven more were carried out at various sites in Italy.
The improvement of structural performances will extend the pavement's service life, thus reducing maintenance operations and the related costs. In addition, once laid, asphalt with Gipave can be 100% recycled, which reduces the emissions of CO2 eq in the atmosphere and the extraction of new materials from quarries and first-use bitumen. Moreover, this new technology also allows the recycling of the plastic, which can be sent to waste-to-energy plants.
In a statement, Giulio Cesareo, founder and CEO of Directa Plus commented: "At a time when the whole world is watching the launch in Genoa of the new Genoa San Giorgio Bridge, we are proud to have participated in this major symbol of hope for all of Italy. The use of Gipave in asphalt, enhanced by G+ graphene, is exactly aligned with the bridge's sustainable agenda and provides Italy with a shining example of the future of infrastructure projects.
"This is a signal that our G+ graphene technology is mature in construction markets and can improve performance and reduce environmental costs. I congratulate our partner Iterchimica on its contribution to the new Bridge"
Federica Giannattasio, Iterchimica CEO, added: "This is an Italian technology to build green, high-tech, highly resistant, eco-sustainable and 100% recyclable road pavements. It generates environmental and economic benefits for users and is a product that helps to meet Green and Circular Economy standards, UN Sustainable Development Goals and the COP 21 Paris Agreement."
