The construction industry pollutes heavily in the CO2 accounts with an imprint of 38% of global CO2 (source). The main part of the emissions comes from materials, where concrete alone makes up 7% of global CO2. At the same time, the current concrete consumption means that we will run out of sand and gravel. Hemboo develops a solution to CO2 and resource shortages in the construction industry that can make it easy, fast, and economical to build sustainably. In concrete, they developed a prefabricated, structural wall element made the of bio-based materials hemp and bamboo that can replace typically used sandwich elements (concrete with mineral wool) with a 90% CO2 saving according to the performed LCA.
