Construction projects regularly generate mineral excavated soil. While sand and gravel can already be processed and used, for example, as aggregate in concrete, cohesive soils with a high clay and silt content have so far mostly been landfilled. The aim was to process and activate these natural raw materials to develop resource-saving and sustainable alternatives to conventional building materials.

MIRO Sustainability Award

The project was part of the BMBF strategy ‘Research for Sustainability – FONA’. The Technical University of Cologne submitted the TOFFEE project on behalf of all partners for the MIRO Sustainability Award. Although the project did not win an award at the ceremony, each participating partner received a certificate of participation in recognition of their commitment to sustainable construction. MC was also delighted to receive this recognition.

The TOFFEE project is a prime example of successful cooperation between science and practice in the development of sustainable innovations in the construction industry.
