Growing Materials with Nature
At Rebound, we believe building materials should be grown. That's why we use biotechnology to ferment natural fibres and mycelium into biomaterials with low energy consumption and without unnecessary chemicals.
We use renewable natural fibers from Danish agriculture, sourced from surplus materials from a variety of crops.
Rather than removing resources from existing value chains, we create new value from biomass that would otherwise be burned or go to waste.
The construction industry needs a greater diversity of material choices and more materials derived from natural resources.

Rebound's products are developed to replace conventional materials where they make the greatest impact, contributing to a more balanced use of natural resources.
Mycelium binds natural fibres into strong acoustic materials while requiring only minimal energy during production.
The materials store biogenic carbon, while nature performs much of the manufacturing process itself.
The result is healthy biomaterials with a significantly lower environmental footprint.

Mycelium Replaces Plastic and Cement as Nature's Own Binder
Natural fibres are fused together through a fermentation process, where mycelium partially breaks down the fibres before binding them into a durable biomaterial. By replacing conventional binders such as plastic and cement, the process significantly reduces both carbon emissions and waste.
The resulting material stores biogenic carbon throughout its lifetime, further lowering its environmental footprint.

In the image, mycelium can be seen growing and spreading as a network of fungal threads.
