Clearing and recovering spoil on our construction sites
Rising to the environmental challenge posed by construction-site spoil, we have sought to offer a reliable, safe solution for optimising resources.
A consortium consisting of Bouygues Travaux Publics, Soletanche Bachy, and Suez has been tasked with building a new metro station (Fort d’Issy-Vanves-Clamart) that will form part of the planned Line 15 underground rail bypass encircling Paris. In the long term, this new line should unclog the Parisian public transport network and serve the surrounding departments efficiently. Here we take a look at the solutions we have devised in partnership with Suez.
How could we manage the 43 million tonnes of spoil produced by construction of the Grand Paris Express transport line ? How could we rise to this serious environmental challenge? Among other fields, Suez has long specialised in handling contaminated land and recovering earth. It has shared this area of expertise with Bouygues Travaux Publics, Soletanche Bachy, and the Société du Grand Paris (public body in charge of new infrastructure in the Parisian conurbation).
- Types of earth are categorised through samples analysed by independent laboratories. The land is then excavated.
- Suez transports the earth to the appropriate recovery and processing centres while ensuring a high level of safety and transparency, and strict traceability of the portions of earth analysed.
- A specially created software program set up by the Société du Grand Paris enables Suez to give information on the site and its processing centres.
In total this complex project involves:
– 180,000 tonnes of earth examined then excavated at depths reaching 40 metres and volumes reaching 1000m3 per day.
– two thirds of this earth is unaffected or only slightly affected by pollution naturally existing in deep-lying earth.
Suez ensures optimal recovery of the earth and helps reach the target set by the Société du Grand Paris: to recover 70% of the spoil.

Objective: zero waste…
Regulatory pressure is growing on how building and public works waste is processed. The sector produces 70% of waste in France (245 million tonnes, 46 million tonnes of which from the construction sector).

Anticipating in construction for reversible and sustainable buildings
This is an entirely new approach to construction, a more ethical and sustainable one. It involves predicting changes in usage, and the reversibility of a building after construction The aim is to be able to change the building's purpose easily to accompany changes in lifestyle and in the regions themselves.

How can we develop and build in the context of “Zero net artificialisation” ?
23,000 hectares: this is the average annual area of natural, agricultural or forest land reallocated to urbanisation in France over recent years, the equivalent of 2.2 times the area of Paris, 33,000 football pitches or 19 million parking spaces. A figure which makes France one of the worst European students with regard to restraining real-estate development. The impact on biodiversity and CO2 emissions are such that there is an urgent need to hold back this effect. Although the target of Zero net artificialisation (ZAN) was written into the national biodiversity plan in July 2018, the strategy, method and means of bringing this into reality remains to be specified. Likewise the search for a denser, viable and liveable urban development model in large conurbations as well as town centres and small and medium-sized towns.

Cities Are Taking Steps to Become Carbon Neutral
Responsible for 67% of global GHG emissions, cities are on the front line of this challenge. Two high-emissions sectors - transport and construction - are of direct concern to them. What are their margins of manoeuvre and trajectories to become low carbon and carbon neutral? What are the major assets of the local scale?

Photovoltaic : where are we?
“At the end of the crisis [health linked to the Covid-19 epidemic], the questions [regarding energy policy] will need to be readdressed.” So said Pascal Roger, president of the Federation of energy environment services (Fedene) to News Tank Cities on 01 April 2020. Currently, new renewable energies represent a prospect for ecological transition for this sector with photovoltaic in the lead, between giant power plants and innovative installations. Where are we ?
