When it comes to natural building materials, there is only a brief example, because perhaps when it comes to natural building materials, when I go into discourse and ask what are natural building materials, the answer is classic wood. Typical natural building material.

One material that I would also like to introduce you to is a panel material, which in this case consists of one hundred percent cellulose, but which is formed very, very thin, can be worked and processed, almost like a sheet of metal. That is why the company is also talking about sheet wood. And that has the impression that a wooden material, where at first glance you may not even see directly, does not even directly notice that it is a hundred percent natural building material.

So I would clearly like to encourage you to research from time to time, to ask questions about the individual materials really to feel broken down to the core in order to find your appropriate materials so that you can use healthy products here.

The issue then becomes more complex when it comes to the composite materials already mentioned. When it comes to composite materials, it is of course not just a matter of looking at which individual materials the composite consists of. Here is an example where you can actually see it quite clearly, both in the side structure and in the front view, that several materials work together in combination here.

The reason for the whole thing is that this composite was created to create a highly absorbent material surface. The different grain sizes visible here, depending on the design distance, if you imagine that this material is used on the ceiling. With high ceilings, you can work with the slightly coarser grit, but you still have a closed appearance, the lower the ceiling, the finer you can work with the granulate here.

You may be wondering now that composite materials are healthy materials, what is healthy about it here. The interesting thing about this composite material, when you look again from the point of view of the raw materials, is that the top layer, the different granules, are made from the same material, in this case recycled broken glass, which ultimately only differs in the grain size, although different in perception, is ultimately exactly the same material from the materiality, from the raw material.

The absorbent insulation material behind it is a special development, which uses a renewable plant, in this case a kenaf plant, to create a circular material that combines renewable, recycled content here. It is a very typical, healthy material, from vapors to healthy living.

As with raw materials, the question is how far do you go here, how precise do you want to be if you want it that way. We actually have planners as well as builders now who say that a material such as the one just shown is suitable for us, because the individual components are all completely (fine?) are.

There are a pleasing number of material developments that show the path already mentioned again and again, including material development by a company that comes from the outdoor furniture sector, which has worked a lot with teak wood there, which also shows the complexity quite a bit. Teak itself is a hundred percent natural material. Not without problems when it comes to the issue of rainforest et cetera. Long transport routes and as this company has considered from the point of view of the overall balance sheet, there are no alternatives that we produce here and can use more efficiently.

And during their trips to find the right teak wood, the company discovered that tons of rice husk are produced as waste in Asian countries, which has so far been deposited without problems. But they then said to themselves that this waste, similar to eggshells, is still too valuable in itself to simply deposit it, cannot be developed from this raw material into a material that ideally has the potential to replace teak wood.

And these efforts have resulted in a hybrid material, a fiber-reinforced hybrid material, with a very high proportion of 60 percent rice husk, 22 percent of rock salts and only 18 percent of mineral oil. This is a development that goes absolutely in the direction of healthy, renewable, ecologically valuable materials. Where you can say that it is not yet one hundred percent healthy down to the raw materials, but the path in that direction has been taken accordingly.
