Porta Samedan is built with recycled building material
The new Engadine shopping center Porta Samedan is taking shape. It is built from recycled building materials. These come from the regional construction company Montebello and the LafargeHolcim subsidiary Holcim Schweiz AG.
The new Porta Samedan shopping center is being realized by Migros Ostschweiz and Pfister Immobilien AG . During these days, the concreting of the floors of the new building is taking place, according to a media release . When it comes to building materials, the partners rely on the circular economy. Recycled products are used for both concrete and cement.
The one main component in concrete is cement. This comes by train from the Holcim plant in Untervaz GR to the Upper Engadin, where Montebello produces the recycled concrete on site. The Holcim product Susteno is used. According to the information, this is the only resource-saving cement in Europe in which the fine proportion of mixed granulate from demolished buildings is used as an additive, which cannot be used in concrete production. Holcim can completely close the building material cycle with Susteno, as this material would otherwise have to be dumped.
The other main component in concrete are the aggregates. "Here we rely on recycling: instead of natural gravel, we use demolition material from the region," explains Flurin Wieser from the Engadin construction company Montebello.
"The Porta Samedan development shows that the building materials industry, with innovative products and solutions, is playing an increasingly important role in the transition to the circular economy and is making a significant contribution to a sustainably built future," said Philippe Rey, Head of Cement Sales German-speaking Switzerland at Holcim Switzerland.
Porta Samedan is scheduled for completion in 2021. Among other things, it will house the first Migros supermarket in the Engadine.
