Infestation with duckweed
TFor the first time in the 48-year history of the Medienhafen, we had an infestation of duckweed. How dangerous is the plant, or does it also have good sides? Duckweed grows extremely quickly and extensively and removes nitrogen and phosphate from the water. This occurs in excess in the Rhine water due to agriculture. Its extreme growth has an impact on the oxygen content and therefore the living conditions in the water, especially for fish and other plants. However, under controlled conditions, waste water can be purified, animals fed or energy generated.

Dragonflies in the harbour for the first time
For a long time there were very few insects in the harbor. Since the plant islands have been blooming, the area is teeming with insects again and the dragonfly is also finding food again. It is always found near bodies of water because its larvae live in the water. This insect spends most of its life flying. It can reach speeds of up to 50 kilometers per hour. In Germany, around two thirds of native species are endangered, twenty percent are even threatened with extinction and are protected species. The main reason for this is water pollution.

Improving drinking water quality
To keep your drinking water fresh and germ-free on the jetty, we have installed "automatic hygiene flushes from GEBERIT". The devices automatically run the drinking water pipes for 5 minutes once a day so that there is no stress from heat or stagnant water in the pipes. In addition, the water in the marina is revitalized by a GRANDER water system.

3 additional underwater aerators installed
The Media Harbour is very rich in fish. Here under the jetties and on the new planting islands, the fish find cooling zones and space to spawn. We have installed three more aerators near the marina building. The oxygen helps the fish when the water temperature is high, but the plants on the planting islands also grow faster.

New plant islands as breeding grounds
The Media Harbour is not only rich in fish, but also in waterfowl. Ducks, moorhens, geese and many other species have previously used the ships' bathing platforms to raise their young. In cooperation with Pflanzinseln Niederrhein, we have now installed the first floating nesting island where they can breed undisturbed.

Our insect hotels
In order to provide wild bees and insects in the harbor with new habitat and food, we have installed the first four insect hotels. The floating plant islands with plants such as purple loosestrife and brooklime serve as a source of food for them.
We would like to thank Asahi Kasei and ONWATER for their support.

New outdoor ashtrays
Unfortunately, visitors to the port still carelessly throw away their cigarette butts. Did you know that there are up to 4,000 harmful substances in a cigarette butt? A single butt with its mix of toxins can contaminate between 40 and 60 liters of water, accelerate the death of fish and negatively affect plant growth. Please dispose of cigarette butts in our ashtray, we will take care of the rest.

Clear Rivers and Rescue the Rhine intensify their cooperations
The Rotterdam-based Clear Rivers Foundation has been collecting plastic from the Rhine and Meuse rivers for years. The special thing is that Ramon Knoesters and his team turn the material into furniture, building bricks, floating gardens and plastic collection stations. www.clearrivers.eu
In 2024, both companies will strengthen their commitment to keeping the Rhine clean.

March – Successful test of our aquatic plants
This year's winter was hard on our aquatic plants in the test and cultivation tank with minus 8 degrees. After we have pruned the plants, they will now be replanted in the Asahi Kasei Garden. The hardy aquatic plants we use clean the Rhine water in the rear harbor basin. You can find more information about the individual plants at: Link

New partnership to protect the Rhine
We are pleased about the new partnership with the Zollhafen Marina in Mainz. Detlev Höhne and Rolf Gast are increasing their commitment to protecting the Rhine. In the first project stage, water-clarifying greenery will take place in the harbor basins. “Simona Ecoplastiq” pipes are being used for the first time as sustainable, fully recyclable floating bodies.

New: Asahi Kasei plant islands in the Vacation Club
Asahi Kasei Europe has announced a groundbreaking partnership with the Marina Düsseldorf marina to improve the climate resilience of the Düsseldorf harbor basin with the “Rescue the Rhine” initiative. A key component are the so-called “plant islands”. These floating modular gardens were equipped with special water-clarifying plants.

New: The plant islands in the media harbor
In search of the optimal shading of the water, we have now entered into a cooperation with the young company “Pflanzinseln Niederrhein”. These floating plant islands are a beautiful and clever product with which we can quickly and inexpensively stop evaporation and at the same time clear the Rhine water of excessive toxins.

New: Underwater ventilation “Smart Bubbles”
To improve the water quality and activate the anaerobic soil environment, the marina is using underwater aerators (Smart Bubbles) for the first time. So far, 6 aerators are used. Because the outside temperatures have reached the 30 degree mark again this year. At 24 degrees water temperature, the oxygen level for the fish drops dramatically.

Action:"Rescue the Rhine N°2"
The marina continues its commitment to shading the water through sustainable greenery. We would like to thank Hanns Josef and Marion Bolten from Düsseldorf for the first sponsorship of our floating apple tree.

Action:"Rescue the Rhine N°1"
With our floating gardens made of recycled plastic (HDPE), we are starting to green and shade the water in 2020. The plants form natural competition with blue-green algae (cyanobacteria) and offer fish and water birds a protected habitat.
