EcoPlanet/Susteno

A resource saving concrete made of processed mixed granulates from demolition rubble

Identification

Susteno is the first resource-saving concrete in Switzerland made of high quality processed mixed rubble from demolition projects. 85% of demolition rubble is recycled in Switzerland, and Holcim found a way to close the material cycle for the remaining 15% that would otherwise be landfilled. This conserves scarce landfill space (around 1200 truck loads in 2020), conserves primary raw materials, and saves 10% CO2 compared to a CO2-optimised Swiss mass concrete (30% vs a type I concrete). The CO2 savings in 2020 were equivalent to 4700 people flying from Zurich to New York. Susteno is also a solution for companies that recycle concrete and mixed demolition waste and are looking for a sustainable alternative to landfilling the unusable fine fractions. Susteno is the next generation of mass concrets with a more ecological footprint and complies with all norms. This solution demonstrates how the construction sector can play a key role in the transition to a circular economy.

Implementation Stories

EcoPlanet/Susteno by Holcim
Implemented by HSG Foundation in Saint Gallen (Switzerland) in 2016

The HSG Foundation – a non profit which aims to promote the University of Saint-Gallen in its development as one of the leading international business universities – used the cement as part of their new learning center construction. They called upon Sou Fujimoto architects for the design and Holcim to supply Susteno 4 materials for the building. For the realization of “the SQUARE” premises, approximately 1,000 tons of Susteno were used among other Holcim materials (EvopactPLUS and EvopactZERO).

Result

By using holcim ecoplanet / susteno forthisproject,a 10% co2 reduction was achieved compared to the use of an optimized swiss mass cement
