The pratice includes demolition and crushing works of motorway riders and bridges over the river for the realization of the 3th lane of the A4 motorway
The assignment includes demolition and crushing works of no. 9 motorway riders, no. 6 bridges over the river and the complete demolition of the viaduct on the River Tagliamento. These interventions are necessary for the realization of the 3rd Lane of the A4 Motorway by Km Progr. 63 + 300 Alvisopoli (Ve) up to Km 89 + 000 Gonars (Ud).
Demolition works will result in a demolition waste production (C.E.R. code 17.09.04), which is equivalent to about 35,000 m3 (about 70,000 ton); all the materials will be reused using several crushing campaigns with relative Environmental impact assessment screening procedure.
The treated waste will acquire different sizes according to the type of use, as indicated in the special tender specifications, and will be reused for the formation both of the bank of the third lane and for the formation of the new junction of new motorway riders.
In doing so, the only waste that will result from this recovery process will be the metallic and ferrous materials that will then be recovered at local recovery centers and / or steel mills.

Evidence of success
This practice is successful because it helps to riduce the amount of waste that usually is thrown in landfills.
Landfilling has often been a cheap way to dispose of waste, but Prandelli Santo Srl believe that reuse, recycling and recovery are better options for managing waste and preserve the environment.
So our company is satisfied of the environmental benefit that we are getting.
Potential for learning or transfer
The promotion of waste recycling and recovery techniques is an urgent necessity, especially today.
We think that is important to reuse the waste as much as possible to preserve the enviroment and prevent the saturation of landfills.
Also, in the case of excessive transport distances, the environmental benefit becomes a burden, so reuse and recovery are potentially the better beneficial options.
The World is still not sufficiently engaging in prevention and reuse, so we hope that this technique will grow as soon as possible and we want to make our contribution to it.
