Environmentally friendly innovation in the construction industry
Griesser has switched to more sustainable aluminum with a reduced carbon footprint. By increasing the use of recycled material and renewable energy, the company significantly reduces its emissions.
Griesser is switching to even more sustainable aluminum. Previously, the internationally active developer of sun protection systems for buildings from Aadorf used aluminum that consisted of 64 percent primary raw material and 36 percent recycled aluminum, Griesser explains in a press release. Griesser now uses aluminum that consists of only 35 percent primary raw material. The remaining 65 percent is obtained from scrap or consumer scrap generated during the aluminum production process.
“Our climate vision envisages complete decarbonization by 2050,” Griesser CEO Urs Neuhauser is quoted as saying in the press release. “In the material area of aluminum, we have the greatest leverage to significantly reduce our CO2 footprint.” The aluminum previously used by Griesser had a footprint of around 4.7 kilograms of CO2 emissions per kilogram of aluminum produced. Switching to the even more sustainable aluminum will reduce this figure by 30 percent to 3.3 kilograms of CO2 per kilogram of aluminum. The press release cites a European average of 6.7 kilograms and a global average of 16.7 kilograms as comparative values.
Griesser is working with two European suppliers to reduce its footprint. They offer certified low-carbon aluminum. In addition to the use of recycled aluminum, the aluminum is produced in Europe using energy from renewable sources and modern technologies, explains Griesser. Compared to conventional production, the production process therefore has “up to five times” lower CO2 emissions.
