Project / Stockholm 2025
Biochar in a
building foundation.
Biochar was integrated into both the aggregate layer and the concrete, combining material performance with long-term storage of biogenic carbon.
- 01Aggregate layer
Most of the biochar was mixed into the layer beneath the foundation.
- 02Concrete
A smaller amount of biochar was added to the concrete.
- 03Materials working together
Cellular glass insulation and lower-carbon concrete with a slag-based binder complemented the solution.
What this case shows
Biochar can be integrated into engineered material layers when performance, documentation and long-term end use are planned together.
From project to carbon removal
Traceable delivery and documented end use provide evidence for separate quantification and verification of carbon dioxide storage.
