On-site recycling IOC/Luca Delachaux

Again in a spirit of sustainable development, the International Olympic Committee (IOC) has recycled all the concrete used in its former administration buildings for use in the construction of the new Olympic House. To make this operation worthwhile from an energy point of view, the IOC decided to recycle as much as possible on site. Such an operation does not allow much in the way of grey energy savings. Rather, the benefits are mainly a reduction in road traffic (less pollution for those living nearby, plus reduced energy and carbon footprint), natural resource savings (no need for new gravel) and the space saved in rubbish dumps.

A concrete mixer and all the other machines needed to sort and crush the concrete were installed on the site. A number of tests were carried out by a specialist laboratory to find the mixture for the recycled concrete that would meet the mechanical needs of the civil engineer. Once the calculations had been made, it was agreed that the recycled concrete could be used in different amounts to create the watertight wall around the Olympic House site, and in the apron and outside walls of the underground part of the building. The ultimate objective is to recycle all the concrete used in the old IOC administration buildings.

“ This approach saved us numerous lorry journeys, natural resources like gravel, which is not in limitless supply in quarries, and space in rubbish dumps, which are starting to reach saturation point. This is the first time we have mounted an operation like this on such a big scale. ”
