• Holcim highlighted a circular construction project in Puchheim near Munich using fully recycled Hebel autoclaved aerated concrete wall panels for a new industrial building.
• About 225 m3 of wall panels from a 50-year-old industrial hall were dismantled onsite, crushed into secondary AAC powder, then reused in new AAC production.
• The recycled material substituted primary sand and binders, targeting lower CO2 emissions while meeting the same quality standards as primary AAC.
• Modular panels supported a 50-meter-long, column-free interior, aiming to speed construction and reduce manual labor.
