OUR MOTIVATION
Price is the decisive factor in the construction industry.
Widespread adoption of new materials comes about through price competitiveness.
Sustainable building will not prevail through appeals, but through competitiveness .
This realization led to the founding of ReWorth 2025. Our approach? To rethink mineral waste streams, for whose disposal we still pay today, as a high-value resource and thereby make circular construction the new standard.

The numbers speak for themselves:
-
92% of all mineral resources that we extract from the ground worldwide each year flow directly into the construction sector.
-
90% of a building's CO2 emissions are "embodied," meaning they are determined by the choice of materials.
-
Mineral construction and demolition waste accounts for over 50% of Germany's largest waste stream.
If we succeed in changing the physical linearity of the construction sector and bringing the concept of urban mining to life, we will unite
ECONOMIC EFFICIENCY, RESOURCE EFFICIENCY AND RAW MATERIAL INDEPENDENCE
At ReWorth, we have a clear mission:
We want to revolutionize the construction industry by transforming construction waste into a valuable resource, thereby creating sustainable, cost-effective solutions for the future of building.
RESOURCE-EFFICIENT, PRICE-COMPETITIVE AND EASY TO IMPLEMENT - REBLOCK BY REBLOCK
What originally began as a project with the United Nations Environmental Programme, we as the COLAB team are currently implementing together with the Fraunhofer Institute for Building Physics using an innovative technology for lightweight building blocks.

The solution lies within our own four walls; let's begin together and build the world of tomorrow.
