New Eco-Efficient Building Processes
ACCIONA is trying to develop more environmentally-respectful building processes to replace those currently in use by way of employing differential technologies and waste re-use and remediation.
End of life tires in fills
ACCIONA has shown another of its lines of research to be a success: the re-use of shredded tires as fill for soil stabilization. A new way of recycling end-of-life (EOL) tires. The M-111 highway was the first time in Europe that a ramp measuring 200 meters in length by 8 meters in height at its highest point had ever been built using shredded tires. A total of 2,200 metric tons of tires were needed or, what is the same, a total of 240,000 tires were recycled, almost the total number of tires which are recycled in Madrid in one year's time.
Biotechnology in soil stabilization
ACCIONA has introduced for the very first time the
use of molecules from sugar cane as a chemical soil stabilizer
instead of the cement and lime used in conventional processes.
These are totally degradable, nontoxic, non-flammable,
non-corrosive liquid enzymes; their use therefore, as well as
having a lesser impact on the land, entails a reduction of CO2
emissions of 28.2 kg per m3.
