P-Campus Lecture Series 2022

THURSDAYS | 15:00 h

In May 2022, the new multidisciplinary lecture series of the Leibniz Science Campus Phosphorus Research Rostock will start. We invited international speakers for the lectures from different disciplines related to the element phosphorus. Look forward to exciting lectures from basic research as well as from applied research and use the lectures for professional exchange.

The lectures will take place on Thursdays at 15:00 h. They are organized online via Webex or, in some cases, as hybrid events and are open to everyone after registration. The presentations will be given in German or English (see respective lecture for details), the slides of the presentation will be in English. Questions to the lecturer may be in German or English.
After your registration you will receive a confirmation e-mail. The access data for online participation will be sent to you on the day of the event.

The lectures will be recorded and made available to P-Campus members and registered participants upon request.

Please make sure that Webex has access to your speaker and microphone, if applicable (test here in advance). If you have any questions about this, please contact Maxi Hoche (maxi.hoche@io-warnemuende.de). If you have any subject-specific questions concerning the lectures, please contact Dana Zimmer (dana.zimmer@io-warnemuende.de). We are looking forward to active participation and exciting discussions.

Lectures

05.05.2022 - Phosphorus control in lakes by external and internal management measures | Dr. Michael Hupfer

Abstract
Eutrophication of surface waters is still one of the most serious environmental problems worldwide because it is linked to existential threats to drinking water supply and food production. In Germany, more than 70% of lakes have too high a trophic level and do not achieve good ecological status according to the EC Water Framework Directive. In most water bodies, phosphorus (P) is the limiting nutrient for primary production, so that controlling interventions are mostly aimed at reducing P availability in the water body. In addition to reduction of P inputs, in-lake technologies are also available for this purpose. In-lake measures can shorten the adaptation time to the desired state, contribute to self-stabilisation and reduce costs. However, some of the methods on the market are scientifically questionable. Current developments aim to develop new P adsorbing materials and enable the recovery of phosphorus as a scarce resource. Using the highly eutrophic Arendsee (Altmark) as a case study, it is discussed whether a reduction of eutrophication is possible despite a long-acting P load via the groundwater and thus whether the requirements of the Water Framework Directive can be fulfilled.

02.06.2022 - The Multifaceted Chemistry of Aromatic Phosphorus Heterocycles | Prof. Christian Müller

Abstract
The diagonal relationship between carbon and phosphorus in the periodic table of the elements has inspired many preparative chemists to synthesize new organophosphorus compounds in which a C-H fragment of a hydrocarbon is substituted by an isolobal, trivalent phosphorus atom.

A prominent example are phosphabenzenes (C5H5P), which are derived from benzene (C6H6) and are the higher homologues of pyridine (C5H5N). These aromatic phosphorus heterocycles possess unusual steric and electronic properties that enable their use in more application-oriented research fields. Recent examples from our group on the chemistry and application of this class of compounds will be highlighted in this talk.

23.06.2022 - Floating wetlands as multi-talents in coastal waters | Jacqueline Berendt

Abstract
Eutrophication is a major problem in coastal waters. Floating plant islands can complement measures to reduce nutrient concentrations, e.g. through agricultural inputs, by removing nutrients (P and N) from local waters. In the past, floating islands have been widely used in the field of wastewater treatment. Their promising potential should now also be taken advantage of in coastal waters, where there are fluctuating salinity and current conditions. The Coastal Union Germany (EUCC-D), which celebrates its 20th anniversary in 2022, has installed floating islands in coastal waters of the Baltic Sea in recent years and investigated their potential for nutrient removal. In addition, floating islands provide other benefits such as creating diverse and lost habitats, increasing biodiversity, improving landscape attractiveness or the growing of halophytes for use in the food industry, cosmetics or medicine. An important consideration for the island installations is the use of sustainable and biodegradable materials, e.g. to avoid plastic constructions and the possible entry of microplastics into the water.
In the lecture, different island designs will be explained, their locations in Mecklenburg-Western Pomerania will be presented and the ecosystem services of the floating islands will be shown. Current research results from the LiveLagoons and BaMS HaFF projects will also be presented.

30.06.2022 - Phosphorus recovery from Wastewater | Prof. Heidrun Steinmetz

Abstract
As a critical raw material, phosphorus is predominantly used in agriculture. Municipal wastewater and subsequently sewage sludge have a considerable substitution potential for mined rock-phosphates. However, there are many technical hurdles to overcome in order to obtain a suitable fertilizer. In this presentation, potentials for P-recovery from wastewater will be identified, starting points within the wastewater treatment process will be shown and different technological approaches will be highlighted. The importance of the type of phosphorus removal in the wastewater treatment process for the selection of suitable recovery technologies is discussed, too, and an outlook on combined phosphorus recovery and enhanced P-elimination is given.

29.09.2022 - The Future Availability of Phosphates | Prof. Friedrich-Wilhelm Wellmer

Abstract
With the exception of the three nutrient raw materials potassium, phosphorous, and nitrogen all other elements can be either substituted: element against element or replaced by other technologies fulfilling the same function.  This does not hold true for the three nutrient raw materials: the plants need them directly. Whereas there are unlimited amounts of potassium in the sea and nitrogen in the air, there are no unlimited amounts of phosphorus on Earth. Although the reserves and resources known are huge, certain circles in science regularly repeat the warning of a phosphorus shortage. This paper critically discusses the so-called "crises-indicators": the reserves to consumption- ratio, the "peak-phosphate-concept", and the country-concentration. The "crises-indicators" are compared with those of other raw materials and it will be shown that a fear of a future phosphate shortage is unfounded, although  there is an urgent need to improve the miserable resource efficiency of phosphate, the only phosphorus ore.
