Start-up of the Week: The magical veggie garden of tomorrow

.”Your sneak preview of the future” is the slogan of Innovation Origins, and that’s just what we will highlight with our Start-up of the Week column. Over the past few days, five start-ups of the day have been featured and on Saturday we will choose the week’s winner.

Innovation Origins presents a Start-up of the Day each weekday

We shall consider various issues such as sustainability, developmental phase, practical application, simplicity, originality and to what extent they are in line with the Sustainable Development Goals of UNESCO. They will all pass by here and at the end of the week, the Start-Up of the Week will be announced.

 

Vienna Textile Lab – Colorful microbial microfibres

Giving clothes a bit of color has been done for thousands of years. Dyes from nature has been used for this ever since prehistoric times. Yet these had their limitations and that meant that certain colours were very difficult to come by. Purple is a good example. Have you ever noticed that this colour can’t be found on any country’s national flag? That”s because purple dyes used to be very expensive. Synthetic dyes came on the market in the 19th century and solved that problem.

Vienna Textile Lab is really going to where it originally all started – back to nature. Another discovery was made in the 19th century: the existence of bacteria. These microorganisms can be an organic and sustainable method for dyeing textiles. The disadvantage of synthetic substances is that they are bad for your health and the environment. And the beauty of this Austrian textile dye is that it is based on an entirely organic process.

Energy Floor – Streets made of solar cells

This Rotterdam team came up with a groundbreaking innovation in 2010. A sustainable dance floor that could generate its own energy using the kinetic energy of dancing partygoers. They collaborated with artist Daan Roosengaarde and this resulted in a luminescent interactive floor. This was world news at the time and the floor was actually in place.

The principles behind this dance floor are still very much alive ten years later; it’ s just morphed into a street tile now. The kinetic energy has been replaced by solar energy, so that anywhere where there are streets, small power stations can be installed. Which means charging stations for electric cars might no longer be necessary. The Energy Floor also monitors traffic flow so that everyone can see exactly where there is available parking space. Any other advantages? A lot of street lighting is switched on when nobody is around. Such a waste! Lastly, it just looks really cool.

Revibe – Electricity out of thin air

On railways, construction sites and in heavy industry, colossuses of machines are in constant motion. These movements cause friction and friction equals energy. However, this energy is still being completely wasted at the moment, even though it could also be used to generate electricity. This is the main starting point underlying the Swedish start-up Revibe. They have developed a compact module that serves as a kind of mini-generator for where there is a lot of kinetic energy present.

The advantages are obvious. Equipment that uses this start-up’s technology no longer need a battery or a power cable! And on top of that, it might be the cleanest form of electricity generation ever. The patented battery is very easy to mount on a vibrating surface and then goes ahead and does the job all by itself. And not insignificantly, the electricity can even be stored so that you can use it to do things like make coffee or something similar.

Spaceflow – The e-VVE and landlord

Homeowners’ associations usually have a rather old-fashioned baby-boomer image. Tenants’ contact with their neighbours or with the manager of an apartment complex tends to happen on an inefficient and decentralised basis. This ought to change; that’s what they thought at the Czech start-up Spaceflow. They developed an app specifically for tenants of residential complexes that was designed to take over all communication concerning residential and communal areas. Think of it as a kind of Facebook, but only meant for people who are part of your building complex.

Through the app you can get in touch with neighbours, request repairs, read service announcements and give feedback. There is no need either for separate keys for the communal areas. The app can also be configured for specific situations in a modular way for property managers.

In theory, the app could even replace your house key. So if you lose your phone, you’ll immediately lose your house key as well. Want to make it even more disastrous? In the event you pay for everything via Apple Pay, you would strike out three times in a row then.

Grow X – Vertically grown top quality vegetables

Human beings have been growing crops horizontally for some 7,000 years now. And as this past century has seen us all of a sudden doing just about EVERYTHING differently, we’re also now seeing a trend with vertical gardens and fields. Why vertical? It’s a bit of the same principle behind skyscrapers; they take up less space and are efficient. Vertical gardens have been around for some time already, but now there are also vertical vegetable gardens. Grow X is an example: they grow high-end vegetables for the more luxurious segment of the market.

Fresh vegetables that are grown in their own region are of great importance to the best restaurants. This is what distinguishes them from the hospitality industry where imported or canned vegetables are on the menu. Entrepreneurs can choose from around fifty organically grown mini vegetables offered by Grow X. The advantage of these mini varieties is that their taste is more concentrated than conventional varieties. Grow X is nowadays a regular supplier to the leading Dutch restaurants.

The fact that the Netherlands is internationally known as a major innovator in the horticultural sector has been confirmed once again by this start-up. It is even not commonly known in The Netherlands that our small country is the second largest food producer in the whole world. And this is not per square metre or per capita. No, this is in absolute numbers. Innovation and efficiency are the magic words here and Grow X is an excellent example of this. It is such an excellent example that we have crowned this ambitious start-up from Zeeland Start-up of the Week!

Start-up of the Day: Vienna Textile Lab dyes fabrics with bacteria

“Bacteria are the most intelligent, environmentally friendly and resource-efficient way to produce textile dyes,” says Karin Fleck, founder of Vienna Textile Lab. “Bacteria occur in nature, can be stored as a strain in laboratories and propagated at any time. They synthesize colors in a natural way”.

Karin studied technical chemistry at TU Wien in Austria. For many years she had various managerial positions at several energy companies such as Vattenfall Energy Trading in The Netherlands and in Germany. When she met Cecilia Raspanti (who had founded the company Textile Lab Amsterdam), she became inspired to use bacteria to make textile dyes. Cecilia had already tried this herself, but without much success. “It is not so much about the challenge of using bacteria as a raw material. More than anything, you actually need a lot of know-how and understanding of scientific methods. You then also have to go about it very carefully. There could potentially be germs among them,” Karin explains.

She had already been working with dyes when she was graduating. But the whole sector was new to her in principle. That’s why she sought support via:

  • Fritsch, a textile dye company in Vienna, which specializes in environmentally friendly dyes;
  • Erich Schopf, a bacteriographer from Vienna, who makes paintings using bacteria;
  • the Institute of Applied Synthesis Chemistry at TU Wien.

Microorganisms tend to produce microbial dyes in response to altered growth conditions. They protect cells from external influences such as salt or temperature stress, light or intense competition. These substances often also have an anti-bacterial effect. Bacteria-based textile dyes have the same properties as conventional synthetic dyes when used on a daily basis.

Karin Fleck elaborates further:

What solution does this bacterial-based textile dye offer and why is that important?

It is an alternative to synthetic dyes, which to a large degree have a detrimental effect on health and the environment. But also particularly for people in the textile industry who are constantly in contact with these dyes. Furthermore, everyone wears clothes and is therefore exposed to the chemicals that they contain. These dyes are currently under critical examination throughout the world. The EU has guidelines on synthetic dyes too. Dyes are banned on a regular basis or their use is restricted. This creates more room for new, innovative dyes. But especially for new production systems which do not rely on crude oil.

What has been the biggest obstacle that had to be overcome?

Our limited ability to hire people. The Austrian labor market is geared towards permanent jobs and employee security. Yet the world of start-ups is unpredictable. Above all, people are needed on a project basis in order to be able to cope with any peaks. You need to be able to react flexibly to the circumstances when you’re a young company who has growth spurts.

What has been a high point so far? What are you particularly proud of?

There have been many wonderful moments. Such as winning prizes. When we first started out, we already won 3rd place at the Climate Launchpad. This year we won the BOKU Start-up Prize from the University of Natural Resources and Life Sciences in Vienna. All the invitations we’ve received have also been very encouraging. For example, for the TEDxCanggu in Bali or for a pitch at CLIX , part of the 2018 Abu Dhabi Sustainability Week.

It’s also great to see how people, customers and organizations from all over the world know how to find us. We talk to people from the US, Indonesia, Sweden, Estonia, the Netherlands, Germany and so on. For instance, I came in contact with Material Connexion in New York. This is a collection of some of the most diverse, innovative materials for industry, local tradespeople, artists and designers. Samples from Vienna Textile Lab have now also been included in their collection.

We derive the most pleasure from everyone who supports us. People who let us know that they appreciate how good our bacteria-based textile dyes are. The experts who really help us out when we can’t figure something out right at that moment. But also local organizations that believe in our success. These include the Vienna Impact Hub or the TCBL, Textile clothing and business labs.

How is everything going at the Vienna branch?

Fine. We can have confidence in the structures and systems. We have had many rewarding and supportive experiences involving funding agencies and universities. There are people here who are promoting us, even when they don’t know us personally. I can’t judge whether things are any better anywhere else. But I know that there is more money available for the biotech sector in Germany and the US.

Where will the start-up be in five years’ time?

By then we will have elevated our manufacturing method to an industrial level. We will have a customer base that will facilitate further growth, and perhaps we’ll be expanding on a global scale.

What distinguishes Vienna Textile Lab from similar companies?

We have opted for solid partners. This in turn makes us stronger and more competent. Aside from that, we want to remain transparent and have discussions with all potential customers or partners. Not only with large corporations, but also with niche companies, artists and designers. That may well make it more complicated, but that makes it all the better as well. We learn a lot through this kind of interaction and are therefore able to position and develop our products much more effectively. Last but not least, we have an extremely wide variety of our most important employees: bacteria.
