Fostering Duckweed - From urine to protein

Installation 2016/2019


«Fostering Duckweed - From urine to protein» haben wir seit Juni 2016 an diversen Ausstellungen, in jeweils unterschiedlichen Formen und Settings, gezeigt. Ein Ziel war jeweils, die Ausstellungs-Spaces mit Wasser zu okkupieren und darin einheimische Wasserlinsen zu kultivieren, welche wir später ernteten und weiterverarbeiteten. Die Schwimmpflanzenkulturen waren aber auch Experiment und Forschungsgegenstand zugleich. Denn, lassen sich die Pflanzen überhaupt halten im kalten Grundwasser einer ehemaligen Zementfabrik oder in verschieden grossen Fund-Gefässen auf dem Duttweilerplatz? Ihre natürliche Umgebung wären nämlich Tümpel und Teiche.
Unsere Recherchen haben überrschenderweise gezeigt, dass sich die Nährstoffe für die Pflanzen aus Kompost und Urin gewinnen lassen. So konnten wir zum einen den Dünger der Pflanzen aus eigenen Abfällen herstellen, zum anderen wurde genau das zu einem wesentlichen, inhaltlichen Punkt. Denn es zeichnete sich ein Kreislauf von Stickstoff, Kohlenstoff, Phosphor, Spurenelementen hin zur Bildung von Proteinen ab.
Statt dem Rückbau nach der Ausstellung konnte unsere „Kunst“ gegessen werden, denn Wasserlinsen sind geniessbar und verfügen über erstaunlich viele Proteine mit allen essentiellen Aminosäuren. An der Finissage ernteten wir die Wasserlinsen, kochten sie nach eigenem Rezept und boten eine Duckweed-Speise für alle an.

Die Recherchen zum Projekt sind auf folgender Webseite veröffentlicht: Fostering Duckweed

In their installations conceived for the Transpalette art centre, the Swiss artist duo Baggenstos/ Rudolf conducts experiments, in a DIY manner, with a freshwater species called duckweed (or Lemnoideae). Duckweed is commonly being thought of as a pest, or spuriously confused with algae. However, this surprising but overlooked aquatic plant has already travelled into space to be tested for its capacity to serve in bio-regenerative life support systems. It is considered for bioremediation and bio-mining purposes, as biosensors for the detection of heavy metals and organic contaminants, for the production of biofuels, and is also touted as the next super-food. In From urine to protein the duo is first and foremost interested in the potential close-knit contiguous human-plant feedback loop emerging in their research: The artists can easily produce the nutrients for these plant creatures, which, in turn, are able to produce an extraordinary quantity of proteins easily used in food. Taking this discovery as a point of departure, Baggenstos/Rudolf started to build simple ecosystems for urine-to-protein cycles and human-plant symbiosis, where duckweed, microorganisms and humans functionally interact with each other – a garden where humans and their actions are not the only rulers and beneficiaries, but just enmeshed in the ecosystem.
Baggenstos/Rudolf researched several sites in Bourges where duckweed is growing, sampled various local species and cultured them in their Swiss studio in Zurich, a biohacker art lab where Lemnoideae are grown in giant aquariums. The collected French species were also analysed for scientific purposes with the help of the Zurich based Landolt Duckweed Collection, which contains samples of every known species of duckweed in the world. At the OU\ /ERT exhibition, different duckweed species are being cultured in colourful basins, and new duckweed based recipes tried out.

In a pond at the edge of a cow pasture, surrounded by wild scrub, near Bannegon France, we found the smallest (Wolffia arrhiza) and largest (Spirodela polyrhiza) duckweed plant.
The pond was all over beautiful green and packed full of the two species in July 2019.
