5.4.5 Resources, waste and materials
- Purchased resources The published data corresponds to resources directly purchased by VINCI companies. The amount of these resources, expressed in tonnes, is obtained from physical data also used by the Group to calculate upstream Scope 3 emissions (see paragraph 5.4.3.3, “Scope 3 greenhouse gas emissions”, page 290). Intercompany sales in the Group are eliminated. Purchases by subcontractors or by companies mandated by the Group are not included in purchased resources.
- Materials produced, including recycled materials This indicator corresponds to the real tonnage of materials (natural and recycled aggregates) that VINCI’s quarries and recycling facilities extract or produce in their own operations.
- Consumption of recycled materials (steel, aggregates and asphalt mix) The percentage of steel of recycled origin was obtained by calculating a ratio based on physical data from suppliers of steel to VINCI Construction companies. The percentages of aggregates and asphalt mix of recycled origin were obtained from physical data.
- Produced waste Waste is defined as any substance or object that the holder disposes of, intends to dispose of, or has an obligation to dispose of. Produced waste includes waste from fixed sites, waste produced by concession users and waste generated from construction or maintenance work for which the contract includes waste management. The amount of waste is expressed in tonnes and obtained from physical data. If multiple Group companies are working on the same project, one as program manager and the others as contractors, only the contractors report on waste tonnage to prevent double counting. Waste produced by the Group includes inert materials, non-hazardous waste and hazardous waste, according to the definitions given by the European Environment Agency and the EU Waste Framework Directive (2008/98/EC).
- Excavated soil This indicator corresponds to the tonnage of excavated soil removed from VINCI company worksites. Soil that is reused on site is excluded from the published data. The published data reflects physical data or, if physical data is not available, estimated data.
- Recovered waste The waste recovery rate is calculated as the amount of recovered waste divided by the total amount of produced waste, both expressed in tonnes. VINCI distinguishes between the material recovery of waste (recycling, backfilling of quarries, etc.) and energy recovery from waste (incineration with energy recovery). The reuse of excavated soils outside of the extraction site is another form of recovery.
