Managing the spoil excavated is a major challenge. The type of soil
encountered varies widely by location, and the speed at which
the earthworks progress requires appropriate, custom solutions.
A single tunnel borer can extract over 2,000 tonnes of earth per day,
and hundreds of tonnes are excavated daily for each station during
the earthworks phase. While the Environmental Code classifies spoil
management as a form of waste management, spoil should no longer
be destined for landfills. Instead, it should be treated as a resource – a
flow of material to be processed and recycled. In line with this circular
approach, Société du Grand Paris has set a target of recycling 70% of
its spoil. To achieve that target, it has implemented strict traceability for
spoil.
