There is a significant increase in sustainable building and materials in Denmark. However, we are experiencing a lack of knowledge about the large-scale reuse of waste resources and bio-based building materials. Therefore, DBI will collaborate with ‘Havnens Hænder’ to develop a new sustainable and circular building material based on the same product technical principles as Hempcrete blocks, but with a lower CO2 footprint.
A significant portion of Havnens Hænder's sales comes from Hempcrete blocks. Hempcrete blocks are a sustainable product that primarily competes with building materials such as aerated concrete blocks. In this project, DBI, in collaboration with Havnens Hænder, will develop a material that uses Hempcrete's technical principles but focuses on binding construction waste with hemp shives.
The goal of the project is to establish a foundation for better reuse of waste resources and to reduce CO2 emissions by replacing traditional aerated concrete blocks with a more sustainable alternative. Prototypes will be continuously tested in indicative tests regarding fire safety, strength, and acoustics to provide preliminary knowledge for further product development.
The project ran until April 2025. It is supported by the Innovation Fund Denmark. The project partner is Havnens Hænder.
