In the second block of healthy materials, I now go deep into the material presentation, where I would like to show what approaches there are in the individual material classes. Accordingly, always seen as an example. Anticipating the really nice thing, you could probably easily fill the time as such with different ideas in each individual material class, but in order to show you the wide range, we'll go through different classes, different materials, and I would like to start with a material experiment on a thesis that impresses me on the one hand and inspires me on the other.

In addition, it is a new development of a material from a person who is now part of the Raumprobe team. This presentation of materials therefore serves as an initial impetus. This is a new sheet material that is obtained from the waste materials from sugar production, sugar beet raffinates, I would love to smell them over the ether, across the screen here. Wonderful smell that emanates from this material and therefore this presentation of the material right at the start to encourage you to try such experiments yourself. Perhaps to become a material developer yourself, a further developer.

We learn this regularly in the submissions for the material prize, which we award annually, that young talent at universities in particular is now driving forward absolutely fascinating material developments year after year and you really still see prototypes like these that there is no need for gigantic research laboratories to develop such approaches, to bring them to market. This then partly goes into products, which of course you might think something like this can be realized on a small scale of a thesis. Scalability is then always one of the factors, as is the case here with this example of a nice upcycling product.

This is a cleaning structure that was also created from a thesis, semester project, by the student looking around here, thinking about which raw materials and waste materials are produced in the food industry and has chosen the very clever combination by saying lime as a material for plasters, paints. It is a very healthy material in itself and has therefore focused on eggshells.

Egg shells are made of lime and has developed an eggshell plaster with these egg shells here. You can actually see it quite well in the colors too, in this case not colored at all, but the naturalness, the natural color, the different shades of brown, beige can still be seen here. Where I myself was actually very surprised when she told me what really considerable quantities of eggshells are produced in the food industry.

A material that I, both the student and us planners, wish for and hope that this material may actually be available as a series product in the foreseeable future.
