Green and High Tech Asphalt for AOC Italia

6 October 2023

Over 6,000 m² of roads at the AOC Italia plant in Filago were renovated using a high-tech and sustainable asphalt system, containing graphene and recovered difficult-to-recycle hard plastics waste such as old toys, old CD cases and fruit boxes. 

Through using this technology, about 2.5 ktons of old asphalt, 227 tons of bitumen (-93%), 3,821 tons of aggregates, 270 truck journeys used to transport materials, over 647,000 kWh of energy (equal to the monthly needs of 2,880 families) and 175,000 kg of CO2 eq (-61%) were saved. In addition, 4,400 kg of recycled hard plastics were recovered and two-thirds of the aggregates used for repaving have been recycled.


Novel technology

A green, innovative and sustainable asphalt made with specially selected recycled hard plastics (such as some types of toys, old CD cases and fruit boxes) and graphene was used for the renovation of the internal transit area of the AOC Italia  in Filago (BG). Iterchimica, AOC Italia, and Vezzola Spa joined forces in their commitment to sustainability, exploiting novel technologies for the construction of the new road surface.

AOC Italia used a special asphalt enriched by Gipave and Superplast technologies. Gipave is a technology patented by Iterchimica based on graphene and hard plastics which is derived from an innovative technology resulting from a six-year research project, conducted by Iterchimica (BG) specialized in sustainable solutions for the road sector, with G.Eco of the A2A Group, the University of Milano-Bicocca and Directa Plus, a graphene manufacturer. 


Green recognition

Gipave has been certified as PSV (Plastic Second Life) technology and Iterchimica has recently finalized an EPD (Environmental Product Declaration) for the system. Superplast is a technology that modifies, enhances and improves the performance of asphalt pavements.

The use of Gipave guarantees greater performance in terms of strength and durability, increasing the useful life of the road surface compared to the incumbent technologies currently used on the market, and greatly reduces environmental impact thanks to a reduced maintenance requirement. 

With regard to the circular economy, the technologies allow reducing the consumption of energy and non-renewable raw materials, while reusable and fully recyclable products and materials are deployed.

"We are very happy to realize together with AOC the new green renovation of the internal roads at the Filago production plant, demonstrating the attention to sustainability and the intention of the companies to apply the principles of the circular economy", said Federica Giannattasio, CEO of Iterchimica. “I would like to thank AOC Italia for adopting Gipave, a patented technology already used for the renovation of the A4 Turin-Milan motorway and for the road surface of the San Giorgio bridge in Genoa".


Great collaboration

AOC has a strong focus on sustainable product development, including low-VOC resins, lightweight carbon fiber-based composite solutions, resins incorporating bio-ingredients, and resins based on post-consumer plastic waste. Filago is home to one of AOC's largest production sites, as well as a major research and development center. 

Up to 50 heavy vehicles pass through the AOC Filago site every day for the delivery of raw materials necessary for production, and for loading finished products shipped to customers all over the world.

"In line with our desire to improve the eco footprint of our company, we are taking multiple actions for reducing energy consumption and emissions from our production activities”, - explains Umberto Colpani, manager of the AOC plant in Filago. “We are very happy that through the collaboration with Iterchimica we can renew the asphalt of our plant with minimal environmental impact".

Vezzola Spa took care of the removal of the previous asphalt and the reconstruction of the wear and binder layers for a total thickness of 10 cm (4 cm of wear with Gipave and 6 cm of binder with Superplast). The company supplied the aggregates of natural and regenerated origin used for asphalt, looking for the best type of material, suitable for pavements subjected to heavy wear, and took care of the laying of 1,450 tons of bituminous conglomerate. Its subsidiary Antonutti Srl followed the laying and milling phases of the asphalt, which uses two-thirds of regenerated aggregates, in compliance with the tight time schedule and the high safety requirements imposed by the Filago plant.
