End of Life

The end-of-life phase includes everything that happens after the service life of the bridge. All the activities and processes associated with this phase are related with the demolition of the bridge and the treatment of the generated wastes. On one hand, demolition activities for the destruction or dismantling of the bridge will be necessary. These demolition activities take into account all the machinery necessary for this purpose. On the other hand, the treatment of generated wastes takes into account a greater set of activities depending on the purpose of the processing. In this case, the bridge will be destroyed, after which all the wastes will be transported to a sorting plant where the concrete and steel will be separated. The concrete will be crushed and transported to a landfill and in this way, the complete carbonation of the concrete [32] and thus a higher fixation of CO2 is assured. Seventy-one per cent of the steel will be recycled and in this way, the life-cycle of the bridge ends.
