What has changed in contrast to the classic car manufacturing? This is a very broad question and I have to tell you that almost everything has changed. The car body manufacture, as we see it here, is completely new. We could have managed to use standard components and standard robots here, but the processing sequence and the individual work steps are completely new. Of course, one of these is the actual gluing, meaning the application of adhesive and the joining. Also part of this are: cleaning steps, testing and monitoring steps, up to the measurement of the body and even the transportation is also another one: For example, in this technology, we no longer need conveyor belts, because the body is so light that the robot simply moves the body from one location to the next. What role does the recycling of CFRP play? Of course we need to establish an entire process chain. Recycling is a component and in terms of sustainability is very significant. With CFRP we have clippings, just as in the processing of steel in sheet metal monocoque construction. And we certainly want to add these clippings to the process chain again. The clippings are shredded, processed into new fibre so new components can be manufactured. For example the roof of the i3 - and also of the i8 - is made of recycled carbon. We do show this for the customer to see that we really get the maximum out of it here.

How efficient is specifically the recycling of the BMW i3? The recycling of BMW i3 is just as efficient as the recycling of a conventional vehicle. This means that with the BMW i3 we achieve a recycling rate of over 95 percent.What individual process steps are taken during recycling? First, the pyrotechnics of the vehicle are neutralized. This means that components such as airbags or belt tensioners are set off in the vehicle. Subsequently, the high-voltage battery is removed from the vehicle and i.e. supplied to Second Life application. Then, during draining, the vehicle is released of fluids and used parts are disassembled from the vehicle. After that, the vehicle goes into the compactor and then into the shredder.

How did the idea come up to give the batteries for secondary usage? For us, the idea came up out of the energy revolution. We know that for the energy revolution we need electricity storage in the future. We have to cover the difference between the generation of renewable energy - solar and wind. The wind blows when the wind blows. And the sun shines, when the sun shines. And not necessarily when our customers need electricity. So we need to harmonize the electricity generated by the renewable energies with the power consumption. What the customers need. And for that we need, we have to put an energy storage device in between. And for this are batteries an ideal element, to stop temporarily store this energy and then deliver it to the customer when the customer needs electricity. And the batteries are also available in vehicles, electric vehicles, so that there we have an optimal complement between energy industry and automotive industry. Is the battery still efficient once it comes out of the vehicle? Well the requirements in the vehicle are very, very high for a battery. It must react very dynamically and cover a very broad temperature range - from -20 degrees in winter to 40 degrees in summer. We do not have these high standards in the energy industry. So we can certainly live with a battery that can no longer meet these requirements, but is still suitable for our purposes.

Why is this form of tanning particularly sustainable? The raw material certainly sets the foundation for the sustainability. This biomass that simply accumulates in the course of food production. And beyond that, we have of course also managed to build a purely sustainable method of production, which was also evaluated and recognized by an independent institute and was appropriately classified as particularly eco-effective.How many tons of olive leaves are used? Well, there are some several tons that are used. More important is, of course, above all, what potential is available. When we talk about these 15 million tons worldwide or 12 million tons of olive harvested in Europe, it's often downright surprising when you hear that 5 - 10% of this fruit crop alone are leaves incurred with the harvest or even afterwards. And these are huge quantities that present themselves to generate a recyclable material and thus produce a beautiful and natural product.

You have been given the task to develop a sustainable car. You get the job, then where do you start? First of all in this project, it was very important for us that we reach the customer, this new customer, which we wanted to reach with the product, that we know him better. Therefore we haven't started immediately with outlines, but have papered a huge wall with many questions on Post-its: What happens when? What are we doing here? Etc., etc. And only when we understood this, understood our customers, this new customers, we have sat down and made the first draft.We have a strong focus on people's experience of materials and the natural aspect. And so we use mainly materials from recycled or renewable raw materials. Why was the focus placed on sustainable raw materials? So our focus was indeed to interpret "next premium", in a light, simple, simply refined way and to focus on renewable and recycled raw materials, as you find them here now. And of course that was our main focus, but on the other hand, it is also important to reduce. So, for example, with natural fiber we just leave materials aside, compared to other components or to other vehicles. This means that we also reduce weight. So the topic lightness was also at the forefront. And so, with natural fiber, were able to reduce up to 30% in weight, compared to other materials that usually are used in the respective places.

How important is a sustainable automotive industry? For us it is very important today and we believe that it will become even more important in the medium run. Why is that? The automotive industry in total produces around 80 million vehicles each year. We can make that more graphic and count it down to a minute, then we speak of 150 vehicles which are produced per minute. So you do not necessarily have to be an expert in sustainability to know that we need to think about alternatives. For example, alternative engines, alternative materials. And in this area we already do very much.Why is the kenaf fiber particularly sustainable? The kenaf fiber is insofar particularly sustainable as it absorbs very much CO2 in the growth phase. This is of course good for the CO2 balance. Another advantage is: It is very, very light and grows in floodplains, which are fertilized naturally by the water. And then we have to do without artificial fertilization and machine processing.
