By implementing several initiatives to optimize resource use and minimize environmental impact, this project serves as a prime example of our commitment to circularity.
Walter Díaz, Head of Quality, Environment, and Energy for the project, explains that 2.3 km of polyethylene pipes from the project's bypass system—temporary infrastructure ensuring brine transport during pipe replacement—have been repurposed for recycling. This initiative promotes the circular economy and reduces waste generation.
Reusing Milled Pavement
The milled pavement from the project has also found a second life. The Sallent City Council will reuse 657 m³ of asphalt from Section VII for future works. Meanwhile, the company Deumal will use 70 m³ of asphalt from the Sant Benet road section to produce new bituminous mixtures.
Additionally, 40 certified PEFC wooden units have been acquired for the project, guaranteeing their origin from responsibly managed forests.
Environmental Improvements
This new infrastructure brings significant environmental benefits: it reduces the salinity of the Llobregat and Cardener rivers, replaces an outdated system with a modern, safer, and more efficient one, and promotes the use of reclaimed water in mining operations, freeing up potable water for other purposes.
The Quality, Environment, and Energy Department ensures compliance with the project’s environmental requirements by reporting relevant data and verifying its accuracy. Furthermore, the circular economy measures implemented are closely monitored to share best practices and replicate them in other projects.
