Yes, a Dutch startup called Respyre has developed a bio-receptive concrete that allows moss to grow on it, creating "living walls" for buildings. This innovative concrete incorporates features like porosity, water retention, and specific nutrients that encourage moss growth. The resulting moss layer can help purify the air, cool buildings, and even act as a natural insulator.
Researchers develop "biological concrete" that grows moss ...
Here's a more detailed explanation:
Respyre's Innovation:
Respyre, a spin-off of Delft University of Technology, developed a concrete mix that is "bio-receptive," meaning it's designed to support the growth of moss.
How it works:
The concrete contains a blend of recycled concrete, organic matter (like coconut fiber or peat moss), and specific nutrients that promote moss growth. It also has a micropore texture that retains moisture.
Benefits:
Moss growing on these concrete structures can absorb pollutants, reduce air temperatures, and act as a natural insulator.
Application:
This moss-friendly concrete can be applied to both new and existing structures, including walls, facades, and even pre-fabricated concrete elements.
Self-sustaining:
Once established, the moss layer is self-sustaining, requiring minimal maintenance and no irrigation after the initial period of growth.
Environmental Impact:
By incorporating nature into urban environments, this innovation helps to create healthier, more sustainable cities.
