Each material has an icon. They illustrate whether a material is biobased and/or circular, whether it concerns a pioneer project or is already available in large quantities and whether it contributes to nature inclusivity.  


Biobased materials consist of nature. You can grow and harvest them. You can build with them and after use, you can compost them and give them back to nature.


Circular methodologies enable the reusability of materials, without losing their value or causing damage to the environment.

Nature-inclusive building ensures that not only humans can live sustainably, but that many plants and animals also get a place to live.
