And we could scale up these natural killer cells, which are hard to grow, also in steered systems without any problems.

And the second project we had was together with the RWTH Aachen in Germany.

And they used two methods.

So they used method you learn in university, power per volume, to scale up a streptomyces.

again and again in the shake flask and therefore you have a lot of shear and you need to calculate this shear correctly in order to have the correct starting point when you transfer it into a steered system and so this was very complex and i can only tell a little anecdote where a colleague of mine here in the company michael wagner was giving a talk at the himmelfahrtstagung in germany about his work on the shake flasks.

And in the next morning at the breakfast in the hotel, he saw elderly gentlemen always looking over to his table.

When he finished breakfast, this gentleman came over, introduced himself as Professor Büx from the RWTH Aachen.

And he's like the godfather of shake flasks.

Marzia Traverso is my name.

I'm a Professor and Director of the Instituto Sostenibilit in Civile Engineering at RWTH Aachen University.

Could we start by very briefly defining what is the meaning of circularity and sustainability and what is the relationship between these two?

Yes, sustainability is a sustainable development that guarantees to satisfy the needs that we have today without compromising the future ability, at least the ability of the future generation to do the same.
