ITC 01-21 Master Thesis: Screening and evaluation of the potential of different biogenic residues to be used for Phosphorus Recycling after being pyrolysed

Organizational unit

Institute for Technical Chemistry (ITC)

Job description

Phosphorus is an essential nutrient and a major economic factor. EU covers its demands by importing phosphate rock listed as critical raw material due to its scarce resource. Recycling of Phosphorus from secondary resources like sewage sludge, animal and biomass residues could act as an important pool.

Thermal treatement of such biogenic residues is proposed as an efficient P recycling alternative. However the value of the Phosphorus recovered is dependent on the degree of compliance to the requirements of the respective market with the fertilizer beeing the dominant one. One important aspect not yet fully understood is the influence and the interrelation between P-rich biogenic residues and the properties of its thermal degredation product to be used as fertilizer. In this frame ITC is exploring the thermal treatment process of biomass pyrolysis and its potential of producing a valuable P-fertilizer product.

The main focus of this thesis is screening of various biomasses, evaluation and selection of the most promising for P recycling purposes. In thiis frame you will plan and excecute as well as evaluate results from lab scale experimentation under variation of feedstocks and process parameters. You will perform various analytics in order to classify and rank the biofeedstocks in terms of their fertilizering value.

The thesis can be written in both Englisch and German Language.
