The construction industry is one of the most resource-intensive sectors of the German economy. The nation’s buildings constitute a vast store of raw materials, harboring some 100 billion metric tons of materials that could be recovered and returned to the material cycle at the end of their service life. Four Fraunhofer Institutes have joined forces in the BauCycle project to kick-start recycling of sand and gravel fine particle fractions that cannot be reclaimed today for reuse in further construction projects. The research team will present the results of their work at the 2019 BAU trade fair in Munich from January 14 to 19. The showcase at booth 528 in hall C2 will feature aerated concrete blocks made of recycled rubble, acoustical building materials, and components made of mineral granulates.
