Optimising resources thanks to the circular economy

Given the growing scarcity of natural resources, VINCI intends to limit its impact by moving towards a circular economy. This includes improving our design and production processes, reducing extraction of virgin raw materials, implementing efficient techniques, adopting effective behaviour patterns, and reusing and recycling.

RETHINKING THE WAY WE CONSUME, PRODUCE AND MANAGE OUR RESOURCES

VINCI intends to limit the impact of its activities by moving towards a circular economy. Doing this entails rethinking our supply chain to reduce the extraction of virgin raw materials, consume mainly reused or recycled products and sustainable materials, and significantly reduce the waste we produce.
This means bringing all our suppliers, clients and partners together to find the best ways to reduce the use of virgin raw materials, and reuse the waste we inevitably generate as a resource for our own or other activities – with a focus on encouraging local solutions. For example, we offer clients recycled materials made with waste generated by our own activities.


VINCI IS MOVING
TOWARDS A CIRCULAR ECONOMY.

A STRATEGY OF CONTINUOUS IMPROVEMENT

Committing to a circular economy approach means revising all our current procedures. The key challenge is to limit our footprint by reducing the extraction of virgin raw materials, implementing efficient techniques, adopting effective behaviour patterns, and reusing and recycling.
Focusing on our sourcing means improving our waste management, especially by developing innovative solutions to reduce and recover both our own and our clients’ waste.

Optimising resources thanks to the circular economy - Our commitments

VINCI’s ambition is to apply a circular economy approach to all our activities.

IMPROVE WASTE SORTING AND RECOVERY

VINCI is taking action to reduce the amount of waste generated by its construction activities and its concession users and to systematically recover it.

ACTIONS TAKEN

Reducing waste at source
• Implementing plans to manage waste materials at worksites.
• Rolling out programmes to phase out single-use plastic products at some entities in partnership with retail brands.

Recovery
• Improving waste sorting.
• Systematically recovering waste (including targets by geographic area at some entities).

PROMOTE CONSTRUCTION TECHNIQUES AND MATERIALS THAT ECONOMISE ON NATURAL RESOURCES

As raw materials sourcing is a central issue, we use eco-design approaches to projects and give precedence to reused or recycled materials.

ACTIONS TAKEN

Eco-design
• Using smaller amounts of resources in construction by eco-designing projects and reducing waste at source.
• Filing patents on eco-designed products.

Supply chain
• Favouring the use of secondary, recycled or reused materials in each major supply chain (aggregates, steel, inert materials, biomass, etc.).
• Encouraging the use of reusable or recycled materials when serving as programme manager on concessions.

EXPAND THE OFFER OF RECYCLED MATERIALS TO LIMIT EXTRACTION OF VIRGIN MATERIALS

Some of our business activities involve producing materials (quarrying, in particular). Their principal goal is to develop more alternatives to raw materials, i.e. offer recycled materials and expand their recycling capacity.

ACTIONS TAKEN

Recycling
• Increasing the number of permanent sites able to take in and process recycled materials.

Promoting
• Promoting our choice of recycled materials.

“Zero waste to landfill” airports

“Zero waste to landfill” airports

After VINCI Airports took over the concession for Salvador Bahia airport in January 2018, it became the first Brazilian airport to set itself the objective of recovering all its waste. The airport’s large-scale environmental requalification programme included creating a new sorting centre with an optimised waste management system. All the airport’s waste was recovered in 2020, compared with 1% before VINCI Airports became the concession holder. The programme also focused on creating a plant to treat all the airport’s wastewater and recycle it in toilets, green areas and airport airconditioning. Salvador Bahia was recognised as “Brazil’s most sustainable aerodrome” by Brazil’s National Civil Aviation Agency and also received several international awards, including “ACI-LAC Green Airport Recognition”.

Aggregate recycling and recovery with Granulat+

In France, annual aggregate requirements amount to 560 million metric tonnes. With 130 Granulat+ sites across France, Eurovia (VINCI Construction) offers a range of alternative construction materials. The idea is to use fewer quarried materials by recycling inert worksite waste. Eurovia, which combines this activity with its quarry business, has become France’s leader in recycled construction materials with an annual production of 12 million metric tonnes.

MILLION METRIC TONNES OF RECYCLED CONSTRUCTION MATERIALS PRODUCED A YEAR.

Fully recycled roads

Fully recycled roads

Eurovia has developed an innovative very-high-percentage recycled road renovation process using a specific mobile continuous asphalt plant designed in partnership with Marini-Ermont. After completing a 1 km test section of the world’s first fully recycled road on the VINCI Autoroutes motorway network in France, Eurovia applied the process to road sections in three French departments (Charente, Charente-Maritime and Vienne). It was able to increase the aggregate recycling rate to 70% by reusing planed material as a new road surface layer directly on-site.

Blastfurnace slag to replace cement

Blastfurnace slag to replace cement

To produce its Exegy low-carbon concrete, VINCI Construction replaces clinker – the main component in traditional cement and largest source of greenhouse gas emissions – with alternative binders made from blastfurnace slag. Ground slag, a by-product from the manufacture of iron, has a small carbon footprint. VINCI Construction also teamed up with specialist Ecocem to develop an innovative solution that activates the ground slag increasing the clinker replacement rate to nearly 100%. Exegy is a way of recycling blastfurnace slag in concrete that still offers the same technical properties as traditional concrete, and notably the same degree of resistance. It was used, for example, to construct l’archipel, VINCI Group’s future head office – the first time it was used for the structural elements of a building in France. At the same time, VINCI Construction is conducting a research and development program into the suitability of other alternative mineral binders.

Reusing worksite materials

Reusing worksite materials

The construction sector is moving towards a circular economy with the 3R concept of “reduce, reuse and recycle”. La Ressourcerie du BTP is a concrete example of the circular economy model. The marketplace, which was developed at the Group’s innovation and foresight platform, Leonard, aims to promote the reuse of materials from finishing works and offer employment opportunities to people on integration programmes. The main challenges posed by this process are identifying the potential of objects and materials, and ensuring their recovery and traceability. 2021 target: after the pilot phase, to take it to the next level and roll out the La Ressourcerie offer.


LA RESSOURCERIE IS A MARKETPLACE THAT ENCOURAGES AND FACILITATES THE REUSE OF MATERIALS.

Encouraging motorists in Lima, Peru to recycle their plastic wast

Encouraging motorists in Lima, Peru to recycle their plastic waste

Pex, the Peruvian automatic toll collection subsidiary of VINCI Highways, enables its users to pay for toll and parking services in Lima by recycling plastic bottles. Lima’s drivers can deposit plastic bottles in a recycling robot which, thanks to artificial intelligence, evaluates the value of the materials deposited and automatically assigns “green credits” for each bottle deposited. The amount can be consulted directly on the mobile application and can then be used as a means of payment for the various services offered by the VINCI Highways subsidiary in Peru, such as subscriptions to Lima’s expressways or parking in the Real Plaza parking lots in the Peruvian capital.

Smart Waste Management

Smart Waste Management

Optimised waste management involves streamlining waste transport. Axians (VINC Energies) helps its clients optimise waste collection. In the Netherlands, for example, sensors placed in the containers alert waste managers when they are full so they can optimize vehicle sizes and collection routes.
