Using recycled plastic for the production of asphalt is the goal of the project financed by the Veneto Region promoted by the Veneto Green Cluster Regional Business Network (RIR).
The project, part of the Advanced Systems for Waste Recovery (SARR) presented by the Green Tech Italy business network, was launched in March 2018 by a working group that sees the joint participation of companies and a university center.To innovate the production of asphalt reducing the use of fossil materials and increasing the disposal of exhausted asphalt, rubber and plastic.
This is the objective that the working group in Veneto has brought together the forces of the Department of Molecular Sciences and Nanosystems of the University of Venice with those of private companies such as Elite Ambiente and Execo of the Ethan group, Chimicambiente, Crossing and IFAF. A project in which they are also collaborating from the USA and Spain, with the University of Alabama and the Aimplas Technology Center in Valencia.
The activity involves using a mixture of plastics and / or waste rubbers for the production of asphalt. The use of additives such as rubber and / or plastic to asphalt is known to improve its characteristics such as wear, resistance to temperature changes, drainage, silence. The first months of common work have served to identify an operating protocol for mixing plastic and / or waste rubber with the asphalt that can be integrated into the existing production process and the classification and retrieval of the available raw materials and selection of those that can be used for the process recovery / recycling. The activity is now entering the stage because the next step will be the start of production tests and the verification of the characteristics of recycled asphalt.On the basis of what has been developed in the previous phases, samples of virgin asphalt and recycled asphalt will be produced in different reaction conditions.
The asphalt samples will subsequently be tested in comparison to traditional asphalts and the subsequent analysis of the results will allow the calibration, optimization and validation of the processes. The industrialization phase will then require the implementation of techniques, today precisely in the implementation phase, with the aim of obtaining a process that has a cornerstone in the search for sustainability.
