The system considered here is based on the life cycle of the bridges (“Fig. 5”) that com-
prises several processes:

The production phase of steel and concrete elements, from raw materials extraction to
the production of finished products
Transportation of steel and concrete elements to the construction site
Erection of the bridge
Use phase
Dismantling
Transportation to end-of-life treatment sites
End-of-life (EOL) phase
