The floating leaves of Azolla turn from green to red as this plant absorbs nitrogen from the water. This is a beautiful thing both for the eye and the environment. Waste water usually includes a relatively high amount of nitrogen which is a bad thing for any body of standing water because it provokes an effect commonly referred to as hypertrophication.
Have you ever seen a lake that was all green and slimy? That’s what we are talking about. Simply speaking, there is less and less oxygen dissolved in this water, which makes it a difficult living place for all life forms that require oxygen… and a paradise for those life forms that do not require oxygen: Anaerobic bacteria. They flourish, and by doing so they release various toxins that are not good at all for all other creatures.
And this is how our Power Plant named Azolla works, absorbing nitrogen from the water. By the way, this makes the rotting parts of this plant a great fertilizer.
The natives of North America use bulrush as a source of food and medicine. However, please don’t ingest the plant from our water treatment system at Boom Festival – you might find it to taste bitter and spicy, because it includes high concentrations of pollutants (as opposed to the one found in a rural environments). The bulrush itself is perfectly fine with that – Bulrush is a bioremediator that extracts harmful substances from waste water, including a number of metals. A perfect symbiosis: This Power Plant can live from our waste water and leaves us with clean water!
Thousands of years ago Papyrus used to be the raw material for the first sort of paper. In this respect, it also used to be the raw material for a paradigm shift, as information could be saved and distributed much easier on paper – an expansion of global consciousness.
Today we use the very same plant in our water treatment system at Boom Festival – and once again, Papyrus is the raw material for a paradigm shift. One the one hand, this plant is an extremely efficient recycler of nutrients. It uses substances in the waste water for its growth, and Papyrus grows rampant. By doing so, the chemical balance of the water is recalibrated. On the other hand, Papyrus captures large amounts of atmosphere carbon dioxide (CO2), it’s a long-term storage for the notorious “greenhouse gas”!
The water hyacinth had a problematic effect when travellers brought it from its natural habitat in the Amazon basin to places like Africa or the United States of America: It grew rampant. However, when used in a controlled environment this beautiful water plant has amazing properties. It absorbs a multitude of harmful pollutants, including metals like lead, mercury, strontium-90, and organic compounds believed to be carcinogenic - in concentrations 10,000 times that in the surrounding water! This makes it an essential ‘Power Plant’ in our organic water treatment system at Boom Festival.
