These filters are, as of now, a first step, which we are supplementing with a large area of knowledge that is also growing significantly at the moment, under the heading of material ecology. There are other factors in this area of knowledge. Bio-based materials, biodegradable, resource-efficient, highly interesting topic, the topic recycled, recyclable.

In addition to the structure using the search filter, there is an area of our material knowledge, specifically material ecology, which is currently also growing strongly as we break down further aspects. There are bio-based, regenerative renewable recyclable materials. Biodegradable materials that are correspondingly easy to return to the material cycle. Resource-efficient materials, from weight savings to the floor covering already seen at the beginning, which can be replaced again without an additional adhesive layer.

The aspects of recycled, recyclable circular economy are examined again with various examples and a whole range of other aspects, which we will now examine in the next blocks.
