Alwe: Grünes Design für eine grüne Erde
No energy consumption
Little maintenance necessary
Alwe is an eco-efficient wall decoration. Space-saving and easy to clean, the Alwe brings life to your wall. The heart of Alwe consists of a living microalgae biofilm, which as an air purifier actively absorbs air pollutants and simultaneously produces oxygen - a green eye-catcher for your interiors.
Alwe - The algae picture
With our algae picture we offer a completely new concept to brighten up grey living spaces. With the innovative microalgae-film technology, rooms and especially walls can be used more effectively.
Function meets design when the algae revitalise grey surfaces with their unique charm. Alwe thus offers exclusive living design and at the same time creates a pleasant room climate.
Furthermore, Alwe is...
...easy to maintain, as the algae only need to be watered every 2 weeks (by refilling the tank)
...sustainable and climate friendly
...a symbol for more environmental awareness and a greener future
ALWE is unique and lovingly handcrafted for you.
The name Alwe is composed of the purely descriptive term "algae wall" and the term "to awe". "Awe" means a feeling of wonder and admiration. The fusion of both terms gives rise to the neologism "Alwe", which is a symbol for our fascination with one of the oldest forms of life on this planet - microalgae.
The current dimensions of Alwe50 are 50x50x5cm. The weight is 1.2 kg when empty and about 1.5 kg when filled.
We already know that the algal biofilms have a very effective CO2-Assimilation. All photosynthetic organisms have two different metabolic pathways:
On the one hand, there is photosynthesis, in which CO2 is bound by light energy and oxygen is produced. On the other hand, there is cellular respiration, which, in darkness or low light, metabolises the glucose built up during photosynthesis as an energy carrier. This process is also called respiration and releases CO2 while consuming oxygen.
The light intensity where there is a balance between respiration and photosynthesis, i.e. exactly as much CO2 is bound as is released, is called the "light compensation point" in biology. However, due to the adapted photosystems of microalgae biofilms, this point is lower than in plants, so that even in weak light, CO2 fixation by photosynthesis still predominates. This makes microalgae biofilms more efficient than plants.
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.
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.
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.
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.
Microalgae are unicellular microorganisms belonging to the class of phototrophic organisms, i.e. carrying out photosynthesis. This means that microalgae, just like plants, use light to bind carbon dioxide, thereby releasing oxygen. In our algae picture Alwe we use uniquely selected microalgae, which can be found in nature especially under stones. As a result, these organisms are adapted to perform effective photosynthesis even under very difficult light conditions - such as those we find in our indoor environments. For this purpose, they have developed extraordinary photosystems that are clearly different from those of plants.
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.
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.
In Alwe there is an artificial ecosystem that the microalgae need in order to survive. Outside of Alwe the microalgae cannot survive and will therefore not be able to spread.
Alwe is also thoroughly checked for leaks before delivery. When Alwe is installed, there are no leaks that could promote the possible spread of algae.
The algae used in Alwe are natural and harmless. They are immobilised on a surface and can be easily collected and disposed of via normal household waste.
From the outside our algae picture is very similar to a living picture with a frame. This of course also means that Alwe can be broken if incorrectly attached.
Our carefully cultivated microalgae belong to the so-called safety level 1, which describes organisms that are unlikely to have a negative effect on health. This means that they are not dangerous to animals, humans, plants or water and can be used without restrictions. Organisms from the food industry such as cultures of yoghurt or baker's yeast also belong to this safety class.
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".
