GeoBod² - Sustainable 3D-printed structures made from recycled materials for the future of construction

The joint research project GeoBod² with PERI Vertrieb Deutschland GmbH & Co. KG focuses on the development of a sustainable, 3D-printable building material based on recycled construction and waste materials such as construction rubble or porcelain waste. The project focuses on formulating a geopolymer-based material that does not require additional thermal activation or ceramic firing, thus offering significant ecological advantages. The novel material approach can achieve energy savings of up to 88% (112 kWh instead of 890 kWh for conventional cement production) and a CO₂ reduction of around 68%.
In addition to significantly reducing environmental impact and costs, the process enables the sensible recycling of waste streams that have hardly been used to date. Its use in additive manufacturing in the construction industry also opens up innovative production possibilities with the potential for shorter construction times, material-efficient designs and new architectural design freedoms.
