To limit the use of natural resources, more recycled materials must be available. VINCI companies work to increase the share of recycled materials used, either in their construction processes or with their partners when acting as programme managers. They also deploy materials recycling solutions, by developing their own recycling sites, improving their techniques to provide larger amounts of recycled materials and working on the environmental benefits of these solutions for their customers.
The Road France Division of VINCI Construction has set the following targets: 80% of sites operating in the circular economy, 25% of asphalt mix made with reclaimed asphalt pavement at worksites, and a twofold increase in the production of recycled materials between 2019 (10 million tonnes produced) and 2030. This issue has garnered increasing interest from customers in the development of innovative products and processes that use smaller amounts of natural resources and energy. Currently a market leader in construction and industrial waste recovery, VINCI Construction is continuing the rollout of Granulat+, its brand that applies circular economy principles to construction materials, throughout France. Forming the largest network of sites for treating mineral waste from the construction and manufacturing industries in the country, 130 quarries and processing facilities equipped with dedicated waste collection, sorting and recycling capabilities have joined the Granulat+ programme. The recycled materials thus become certified, quality aggregates. Each Granulat+ site sorts all the waste collected, optimises recycling and recovery, and guarantees traceability of the waste treated. The programme aims to improve the treatment of recycled materials so that they can be used for more noble purposes. For example, excavation material from construction sites, which used to be considered final waste, can now be fully recovered. Granulat+ sites are spread throughout France, forming a dense network that favours short circuits and optimised packaging that rationalises consumption (big bags for urban or small-scale worksites). Progress in recycling techniques should eventually pave the way towards “perpetual quarries”, which would operate without virgin mineral deposits.
When acting as programme managers, VINCI’s concession companies are also involved in promoting recycled materials by including materials recycling requirements in their programme specifications. At VINCI Autoroutes, pavement renovation contracts include targets to maximise reuse of asphalt mix generated by worksites as new asphalt mix (see paragraph 3.3.1.1, “Responsible sourcing actions”, page 241).

VINCI Construction develops innovative solutions. Since 2015, its Road France Division has been using a solution that recovers up to 100% of materials from old road surfaces and uses them to build new roads. To reach that target, the next-generation TRX 100% continuous mobile asphalt plant was eco-designed, and a new approach to the formulation methodology was developed to guarantee asphalt mix quality. This approach involves collecting 100% of the pavement milled to prevent waste, while limiting the use of natural aggregates and bitumen. The technical department for the Greater Paris area has also created a road material out of recycled plastic that is recyclable and does not contain bitumen. An initial 12 sq. metre test demonstrator was built, and the project received further support from the department of Yvelines west of the French capital to use the material to lay a 100-metre section on a bike lane in 2022.
Land recycling refers to developing property on obsolete land that has been restored and repurposed because it no longer serves its previous purpose or the buildings on it have fallen into disrepair. The notion of recycling applies when activity has stopped or is planned to discontinue in the near future. Examples of land to be redeveloped include abandoned industrial facilities, dilapidated housing, polluted land, and obsolete office complexes or shopping areas (see paragraph 3.4.3.1, “Actions to reduce impacts”, page 250). VINCI Immobilier has set a target to generate more than 50% of revenue through land recycling by 2030. This commitment is demonstrated through actions in the areas of soil remediation, resource conservation and avoiding land take. Significant progress was made towards this goal in 2022, with more than 57% of VINCI Immobilier’s revenue generated through land recycling.
