Our philosophy
Solaga is a biotech company, which has made it its business to free the air from harmful pollutants. To achieve this goal, we take advantage of the morphological properties of microalgae.
mission
Our mission is to rid the air we breathe of dangerous pollutants so we can all live longer, healthier lives.
vision
Our vision is to establish algae in society. Through the implementation of our projects, algae should be able to be used as biological air purifiers in all areas of life.
technology
Our technologies are based on the natural properties of microalgae. In nature, the small organisms use air pollutants as a nutrient medium for their growth.
Our solution
Neben Großprojekten wie Fassadenbegrünungen und urbanen Filtern für Innenstädte möchten wir vor allem Bereiche, in denen wir Menschen uns am häufigsten aufhalten, von Luftschadstoffen befreien. – Dem eigenen Zuhause sowie dem Arbeitsplatz.
Hierfür entwickelten wir den Mikroalgen-Biofilm, bestehend aus lebenden Algen. Diese sind aufgrund ihrer physiologischen Eigenschaften in der Lage Luftschadstoffe wie Feinstaub, Stickoxide und weitere gesundheitsschädlichen Chemikalien aufzunehmen, umzuwandeln und als Nährmedium für ihr Wachstum zu verwenden.
algae wall
Ein Wasserfall der über einen Biofilm aus Algen fließt.
Diese Algenwand ist als Raumteiler oder Wandbegrünung für ihr Büro konzipiert. Sie besteht aus Biofilmen, welche als natürliches Material für die Absorption von Schadstoffen fungieren und dabei Sauerstoff abgeben. Die großflächige Begrünung und der automatisierte, sichtbare Wasserlauf machen die Algenwand zu einem echten Hingucker.

Algae picture
Alwe das Algenbild ist ein öko-effizientes 50x50cm großes Wanddekor, das die biologischen Eigenschaften der Mikroalgen nutzt, Luftschadstoffe zu binden und unschädlich zu machen.
Thanks to the natural chimney effect inside the picture, this is completely self-sufficient and noiseless.
Just hang your Alwe on the wall like a conventional picture and it will immediately start cleaning your air.

projects
Multifilter
In development
Urban air purification
Algae, unlike plants, do not need a specific substrate - no "soil". In the urban algae filter, algae arranged in multiple stages remove pollutants from roads and industrial plants.
facade greening
In development
Green facades
The research is focused on the development of new facade elements and builds on the vertical use of algae. At the end of the project, the first facade elements for houses and cities that are greened with algae will be manufactured.
biogas
In development
Green energy
Algae not only absorb pollutants, but also produce valuable materials in the process. Solaga deals with the entry into a circular economy and researches the production and use for the bioeconomy and green energy sources: hydrogen and biogas.
FAQ
Microalgae are unicellular microorganisms that belong to the class of phototrophic organisms, i.e. they carry out photosynthesis. This means that microalgae, just like plants, use light to bind carbon dioxide and release oxygen.
Alwe - The algae image uses specially selected microalgae, which are found in nature especially under stones. As a result, these organisms are adapted to be active even under very difficult light conditions - such as those we find in our interiors - and to carry out effective photosynthesis, among other things. For this purpose they have developed extraordinary photosystems, which are clearly different from those of plants.
Microalgae have a more flexible metabolism than plants, for example, and can therefore break down a large number of pollutants.
The current dimensions of Alwe50 are 50x50x5cm. The weight is 1.2 kg when empty and about 1.5 kg when filled.
How does Alwe improve air quality?
Biologisch korrekt ausgedrückt handelt es sich bei den Algen, um Blaualgen also Cyanobakterien. Diese sind an Schwachlicht angepasst und besitzen spezielle Pigmente, welche die Photosynthese noch bei gerinsten Lichtstärken ermöglicht. Das macht Mikroalgen-Biofilme effizienter als Pflanzen und auch noch zu Luftverbesserern an Orten, wo Pflanzen gnadenlos eingehen.
In investigations with the Federal Institute for Materials Research and Testing and the Technical University of Berlin, we have also discovered that microalgae biofilms can effectively bind air pollutants that are hazardous to health, such as nitrogen oxides and fine dust.
Initial tests at the Federal Institute for Materials Research and Testing also point to the reduction of volatile organic chemicals (VOCs) escaping from paints and building materials. Microalgae have a more flexible metabolism than plants, for example, and can therefore break down a large number of these pollutants.
Where do I hang my Alwe most effectively?
Microalgae need light for their metabolism. Our algae picture is therefore best suited for rooms that are at least partially exposed to the sun.
However, please avoid attaching Alwe to surfaces that are often exposed to direct sunlight. If there is too much sunlight, more water will evaporate and the microalgae may start to break down their photo systems. The result is the fading of the biofilm. Should this happen, do not panic: Just leave Alwe in a shady place for some time and the biofilm will regenerate.
How much maintanance does Alwe require?
When designing Alwe, it was particularly important to us to keep the handling simple and manageable. That's why there is a small water tank in each Alwe, which needs to be refilled approximately every two weeks.
Does the colour of Alwe change over time?
Yes, Alwe consists of living algae which adapt to the local light conditions. In shady areas the algae take on a deep green colour, as the micro-algae accumulate more pigments to absorb light more effectively. In semi-shade areas, the micro-algae need less pigments for successful photosynthesis and thus get a rather juicy and natural green colour.
In direct sunlight there is an overflow of energy in the algae. Under certain circumstances, this may cause the algae to actively break down their photo systems. The result is a colour change to light green or yellowish.
Algae films have not yet been researched in the long term, as these materials are completely new. However, we have not been able to identify any time limits in our previous R&D projects. Some of our algae films are already 4 years old and still healthy and productive, which is even more important. As algae films are living materials, no general statement can be made about their lifetime, as this obviously depends on care and local conditions. As far as we know, however, our biofilms are very robust, making them suitable even for users with brown rather than green thumbs.
With the purchase an Alwe we guarantee a minimum service life of 6 months. If problems occur within this period, you can return your Alwe without any problems and have it replaced by us.
Even after this period of 6 months you can of course always have your Alwe checked by us or you can try out one of our new biofilms. Please feel free to contact our service team.
Why are microalgae more effective than plants?
In interiors, lighting in particular differs from natural light. Even with perceived bright interior lighting, the photosynthetically activating radiation is very low. This is because normal indoor lighting lacks the red and violet components of natural light that most plants need for photosynthesis. The microalgae biofilms we use, on the contrary, have special pigments that enable them to use light outside the red and violet spectrum for photosynthesis.
In addition, microalgae do not have roots or a stem and are therefore metabolically more effective compared to plants.
Unsere sorgfältig kultivierten Mikroalgen gehören zur sogenannten Sicherheitsstufe 1. Diese beschreibt Organismen, bei denen es unwahrscheinlich ist, dass sie sich negativ auf die Gesundheit auswirken. Sie sind also weder für Tiere, Menschen, Pflanzen oder für das Wasser gefährlich und ohne Auflagen anwendbar. Zur selben Sicherheitsklasse gehören auch Organismen aus der Lebensmittelindustrie wie Joghurt-, Bäckerhefe- oder Sauerkraut-Kulturen.
Our biofilms are produced under sterile conditions. Only when the biofilms have formed their characteristic protective skin layer are they released by us for usage in the algae image "Alwe".

Air pollution
The World Health Organization (WHO) estimates that life expectancy in Europe will be reduced by up to 3 years due to the inhalation of air pollutants such as particulate matter and nitrogen oxides. Scientists at the Max Planck Institute for Chemistry and the University Medical Center Mainz calculated that, on a global average, life expectancy worldwide will be reduced by a staggering 2.9 years, resulting in around 9 million premature deaths. And the trend is upward. This makes the consequences of air pollution even more serious than cardiovascular risk factors such as cigarette smoking (2.2 years).
We as a company would like to stop this trend. With our biological, self-sufficient air filter system made of microalgae, we have declared war on air pollution!
