It is an award-winning invention: Dr. Sebastian Porkert has developed a cleaning system, the micro-plastic and pharmaceutical residues from the wastewater filters. The wide-Brunner says: "This is my modest contribution to a better environment and for the Generation of my children."

Breitbrunn – Dr. Sebastian Porkert (35) is "the daddy with the water line". So at least the two-year-old Sylvester defined the invention of his father. The co-founder of the Start-Ups Ecofario in Munich has developed a system, the micro-plastic, and at the same time drug residues from the waste water filter can. A project that was awarded the German sustainability prize for young companies, "the Next Economy Award 2020",.

, and earned a doctorate diploma in engineering in the field of paper technology, where he currently earns as a self-employed optimization engineer his money Studied. The issue of plastic in the waters employed Porkert, at the latest, since he has worked a couple of years as a project Manager for a paper manufacturer in Hainan. A South China island, which is washed in a romantic from the sea and at the same time of a lot of plastic, told Porkert. He remembers foil-wrapped plates and bowls in the Restaurant, which has thrown the waiter after the meal, which included a tablecloth into the sea.

plastic bobbed on the waves around Borneo, where he was on the boat by plastic bottles and bags plowed, before the Diving team moved into clean waters. Eight years ago, he read about a study that examined the sediments in the lake. "A group of researchers from Bayreuth, has found that the lake is completely full of plastic," says Porkert. This meant that the Ammersee or Starnberger lake would also be impacted. Now it had been busy, says the father of two children.

Grew up in the book, he lives today with his family in Breitbrunn. The lake belonged to his everyday life. And one day he decided to no longer sit idly by while year 330 000 tonnes of Microplastics end up in Germany's waters. "Four kilos per head," he says. Most of go via the washing machine, tyre abrasion or the industry sewage. The wastewater industry have already responded. Modern systems could, for example, single, 95 percent of micro-plastic, white Porkert. Filter – in his eyes, but not the optimal technique.

He speaks of a wear part with enormous maintenance costs and an "energy killer, because the finer the particles are, the higher the pressure must be I the water by driving". The idea for its cleaning system came to him literally in a dream One night, he suddenly stood straight up with the inspiration in bed, a hydro-cyclone to adapt to the micro-small water polluters are almost to 100 percent. The hydrocyclone is a centrifugal separator for liquid mixtures, the he knows from the paper industry and is since more than 100 years in the cleaning process is applied. "However, only for larger particles, such as glass or Sand," says Porkert. The difficulty was that the micro-plastic is not only invisible to the eye, but "very close to the density of water".

"My humble contribution for a better environment"

The implementation was a success: "We changed the technique to the extent that the micro-particles can be filtered out," he says. "We" are the Director of Porkert and Adrian Scholl, and Stefan Tomme and Robert Krapez, have developed a so-called end-of-pipe solution, i.e. at the end of the cleaning chain installed system. The Trick is that the water is helically wound through the tube-like member, so that the resulting centrifugal forces push the plastic particles to the inside and secrete. "In a passage, we are filtering more than 95 percent of the micro plastic from the water", so Porkert. The filtered particle flow with a portion of the water back into the System and go through the cleaning process, until they can be well separated. A positive side effect is that the plastic particles of drugs remains a magnet to attract and also preparations of the pharmaceutical industry from the wastewater disappear.

thanks to a design that is now patented and award prizes. It is virtually maintenance-free. The mobile pilot plant should be in a couple of weeks at the Start and potential customers, such as wastewater treatment plant operator or industry could be presented to the company. Scholl and Porkert have already invested a six-figure sum out of their private fortune in the invention and a low-interest loan in the amount of 400 000 Euro. The donated a dedicated lady who wanted to invest this amount in something "Meaningful". After she had read an article about Porkert, she logged. "Convinced you that I have chickens in the garden," says Porkert, laughing. "Who has chickens, must be a nice guy", she found.

The amount is sufficient for the pilot plant and first steps in the direction of marketing. "We pay no salaries," says Porkert. And you are in need of further investment to build the plants. The children of Sylvester (2) and Lilly (6) are fire and flame for the project. Finally, the Ammersee, where they may grow up as the father. Porkert: "The cleaning system is my humble contribution for a better environment and for the Generation of my children."
