Morand Constructions Métalliques builds its first decarbonized steel structure
Morand Constructions Métalliques installed the first decarbonized steel structure in Switzerland for the construction of a new car dealership. As a result, the carbon footprint of the construction has been reduced by a factor of seven compared to classic steel.
The metal construction company Morand Constructions Métalliques based in Enney has built Switzerland's first supporting structure made of decarbonized steel for the newDIMAB car dealership in Rossens. At 333 kilograms of CO2 per tonne, decarbonized steel releases seven times less carbon dioxide, according to a statement from Stahlbau Zentrum Schweiz ( SZS ). Classic steel from the steel mill causes 2300 kilograms of carbon dioxide per ton.
According to the information, the ecologically sustainable steel beams were produced in an electric arc furnace from scrap steel and with 100 percent renewable electricity. At 600 kilograms of CO2 per tonne, the recycling of steel also releases comparatively few greenhouse gases and has been common practice for more than 100 years. If electricity from 100 percent renewable energy sources is also used during production, "the environmental impact of decarbonized steel is almost halved – and at a small additional price of 2 to 4 percent," it says.
