Living algae pictures provide naturally better air indoors. With the green superpowers of microalgae Alwe™ takes harmful air pollutants, such as CO2Nitrogen oxides (NOx)Particulate matter and Chemicals (VOCs) and deactivates these.

Microalgae are much better suited for indoor use because they can use light much more more efficient compared to plants as they are better adapted to low light conditions and oxygen even in artificial light .

With Alwe™ Function meets Design. The natural air cleansing know from plants or algae are combined with space-efficient design. 

What our customers say

"I bought this painting for my husband and his doctor's office in his surgery as a Christmas present. Super service. So now our algae are hanging in the practice and provide good air - really works! And it is a great eye-catcher. My husband is often asked what it is. Also inquiries from our side are answered immediately. We can only warmly recommend Solaga. Great team with great service - thank you !"

"I travel a lot in my job and especially at home, nature does me good. Since I live in the backyard, I would rather have my apartment as Designate plant cemetery. With my Alwe I finally found something for my "un-green" thumb."

We have an air problem.

Humanity is growing, cities are getting denser and our breathing air is getting worse.

Air pollutants affect us every day. As an invisible problem, we usually only recognize it when it is too late.


WHO

The WHO estimates that approximately 91% of the world's population live in areas where WHO guidelines for air pollution are exceeded. 

These violations cause the death of about 4.2 million people every year.

Alwe

About 30 - 50 % of the pollutants of a room with a surface of 25 m² are absorbed by Alwe.

This was confirmed by measurements taken at the Technical University of Berlin and the Bundesanstalt für Materialforschung und -prüfung (BAM) .

Green walls as air purifiers

An air purifier for your home and office

Alwe, our natural square garden for the wall, not only contributes to a natural atmosphere in your interiors, but is also able to effectively filter air pollutants from your indoor air.

The advantages of our algae picture, compared to conventional plants and pictures in the living room and office, are numerous:

Our algae picture is an air cleaner, a humidifier and a modern piece of furniture at the same time. Thanks to our microalgae biofilm, an oxygen producing photosynthesis with minimal space requirements is achieved. In this way, our algae picture creates a pleasant room climate much more efficiently than ordinary plants and binds the air pollutants in your rooms. In addition, Alwe50 is not just a green picture, but with its minimalist design it is an extraordinary eye-catcher with living, breathing materials. This makes Alwe ideal for a more natural and modern design of your living and office spaces.

FAQ

Microalgae are the ancestors of complex land plants. Fossil finds indicate that these organisms have existed since 2.5 billion years and have laid the foundations for the existence of higher life forms through their mass production of oxygen. Cyanobacteria, i.e. blue-green algae, are also commonly classified as microalgae. Together with the rainforests, they are among the largest oxygen producers on the planet.

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 specially selected microalgae, which can be found in nature under stones. As a result, these organisms are adapted to perform effective photosynthesis even under 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.

Alwe is the world's first living algae picture that actively improves the ambient air. 
It is a natural air purifier and eye catcher in one.

The dimensions of our algae picture Alwe are 50x50x5cm.

Alwe consists of a special algae film in an ingenious frame. Why ingenious? There are openings on the sides of the frame. This is where the room air flows in. The algae filter out air pollutants, and because they heat the air by photosynthesis, the air rises out through the upper openings. The resulting chimney effect creates a natural circulation of air.

Normally algae need a lot of water. However, by means of a special ripening process, we make algae grow very densely on a surface and form a natural protective layer. This protective layer is called the exopolysaccharide layer and protects the algae from dehydration, contamination and other stress factors. This special type of growth therefore makes the algae durable and reduces its water requirements by a factor of 100 compared to other types of cultivation for algae. 

Algenfilme und deren Lebensdauer sind größtenteils ein wissenschaftliches Novum und noch nicht langzeitlich erforscht. Wir haben jedoch festgestellt, dass selbst Algenfilme, die bereits 4 Jahre alt sind, weiterhin aktiv und stabil bleiben. Da es sich um lebendige Organismen handelt, kann man dennoch keine pauschale Aussage bezüglich der Lebensdauer der Algen treffen, da diese selbstverständlich auch von der Pflege und den örtlichen Gegebenheiten abhängt. Solange sie regelmäßig mit Wasser versorgt werden, leben sie bis zu mehreren Jahren.

No, the microalgae cannot spread. Inside Alwe there is an artificial ecosystem that the microalgae need in order to survive. Outside of Alwe the microalgae are not viable and cannot spread. Alwe is thoroughly checked for leaks before delivery. We can accordingly guarantee that 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 bio bin or normal household waste.

Rein äußerlich ist unser Algenbild einem Bild mit Bilderrahmen ähnlich.

Our carefully cultivated microalgae are organisms which belong to the so-called security level 1. This means organisms that are unlikely to have a negative effect on health. They are therefore not dangerous to animals, humans, plants or water and can be used without any restrictions. Organisms from the food industry such as yoghurt, baker's yeast or sauerkraut cultures belong to the same 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".
