Resource inflows are the products and materials used by the Group and its subcontractors (upstream value chain). The published amounts are expressed by weight. For VINCI, the most significant resources are the tonnage of aggregates, bitumen, asphalt mix, concrete, steel and wood. These resources may be purchased or extracted from quarries operated by VINCI companies. The definitions of these indicators and the data collection methods used are detailed in paragraph 5.3.5, “Resources, waste and materials”, of the methodology note, page 276.
Consumed resources
Consumed resources amounted to 75 million tonnes in 2024, 10% of which were recycled or reused. Bio-based materials, namely wood, represented less than 1% of consumed resources in 2024. Furthermore, 23% of the wood used was certified.

In 2024, VINCI companies generated and managed 27,927,000 tonnes of waste and materials. Inert waste and excavated soil accounted for 92% of this volume, mainly coming from the Construction business. These figures are likely to change significantly from year to year depending on the types of worksites in progress and their rate of advancement. For example, construction work can occasionally generate substantial amounts of excavated soil on large projects, while concessions generate a relatively stable amount of waste over time, at constant scope.
In 2024, more than 60% of the waste produced by VINCI companies was recovered. This recovery rate varies considerably based on the type of waste or material (16% on average for hazardous waste compared with 87% on average for inert waste), as well as on the region where Group companies operate. An average of 83% of the waste from VINCI Construction companies in France is recovered, versus 65% for the rest of the world.
In 2024, hazardous waste totalled 481,000 tonnes (less than 2% of the Group’s total waste) and included paint, aerosol sprays, solvents and waste electrical and electronic equipment. VINCI companies do not handle radioactive waste treatment.
In 2024, to develop reuse practices in the Building France Division of VINCI Construction and at VINCI Energies Building Solutions in France (see under “Actions to promote the use of construction techniques and materials that economise on natural resources” in paragraph 2.3.2.1, “Promoting the use of construction techniques and materials that economise on natural resources”, page 220), more than 7,000 tonnes of materials were included in a reuse programme. This volume includes materials that came from a reuse programme, such as ventilation ducts recovered during a cleaning operation and then refurbished for use in a new construction project. The figure also includes materials sent to reuse centres, such as false floor tiles carefully removed during a rehabilitation programme for reuse on a third-party project.
