Phosphogypsum as a mineral resource for bioprocesses

About PG-BIOPRO The project concept is to develop integrated biotechnological solutions to produce biofuels and organomineral fertilizers. It is based on the use of organic waste as carbon substrates and phosphogypsum as a source of nutrients and trace elements for the growth of microorganisms during anaerobic digestion.

Project aims:

The project will explore the use of phosphogypsum (PG) a chemical waste after fertilizer production from phosphate rock by the wet acid method. Environmental concerns and increased costs of PG stockpiling call for better use.

In short, our project aims to:

  • Research on PG as a nutrient resource for microbial associates during anaerobic digestion of organic waste;
  • Develop a taxonomic classification and review of metabolic pathways of PG compound transformation with the use of electronic KEGG, MetaCyc and EzTaxon databases;
  • Evaluate the fermentation waste properties as organomineral fertilizer using Life Cycle Assessment (LCA) approaches.

Project duration: 2023-2025

CZU budget: This project has received funding through the MSCA4Ukraine project, which is funded by the European Union.

Project team: Assoc. Prof. Dr. Yelizaveta Chernysh (main contact); Assoc. Prof. Dr. Hynek Roubík (supervisor); Ing. Marek Jelínek (administrative point)
