Do you want to contribute to the development of solutions for recovery and
recycling of phosphorus that are more sustainable?
We are looking for a dedicated, well-organized, communicative and highly
qualified post doc, to carry out the project described below, in the Soil
Fertility group at the Department of Plant and Environmental Sciences,
University of Copenhagen.
The post doc project will unfold within the framework of PROCESSOR –
Phosphorus recycling from complex scarcely soluble societal resources –
letting the soil do the work
The project will be executed in collaboration with partners from ETH
(Emmanuel Frossard and Astrid Oberson), University of Rostock (Peter
Leinweber) and Department of Geosciences and Natural Resource Management,
Copenhagen University (Carsten Müller).
Recycling of societal resources of phosphorus (P) defined as sewage sludge,
meat and bone meal and their corresponding ashes is an essential step towards
a circular green economy. We propose that the resources can be used ‘as they
are' without further treatment, since potentially toxic element (PTE)
content in sewage sludge (and its ashes) has decreased in many European
countries, in some cases close to background levels, while other contaminants
in sewage sludge are of low concern. Bonemeal has a very low content of PTE's.
However, the longer-term phosphorus fertilizer value of these resources and
their intricate interactions with a suite of soil characteristics is very
sparsely understood. In this project, we will for the first time address this
issue across a range of agronomically important European soils, using relevant
complex societal resources. By doing so, we will be able to formulate a
strategy for efficient use of these resources in Europe to decrease the import
of phosphate, which has been identified by the EU as non-substitutable and of
high economic importance.
The work of the postdoc project will be mainly centered on characterization of
soils and P-containing products with solid state methodologies, supplemented
with analyses of P availability with isotope exchange kinetics or ion sink
assays, and complemented by routine wet chemical methods. The work on P
speciation in soils and societal P resources will be carried out in close
collaboration with another post doc working on long-term phosphate dynamics in
