Type of project: MSc internship
Duration: minimum 6 months start from March 2026 or later
Location: Wetsus, European center of excellence for sustainable water technology (Leeuwarden, the Netherlands)
Allowance: The maximum Wetsus allowance for this internship is 425 € per month. Grant holding students (i.e. Erasmus or other) receiving financial support of less than 425 € per month can apply for a top-up supplement to the maximum allowance.
Project description:
Phosphorus (P) is a critical nutrient primarily derived from non-renewable phosphate rock, and its excessive release into the environment contributes to environmental problems such as eutrophication. Animal manure, particularly cow manure, represents the largest secondary source of phosphorus that can be sustainably recovered and reused. In the Netherlands alone, 74 million tons of animal manure are produced annually, with cow manure accounting for 83% of this amount.
This project focuses on developing an innovative process to optimize the simultaneous recovery of calcium phosphate (CaP) and methane within a single bioreactor. The recovered CaP can be repurposed as fertilizer, supporting sustainable agriculture, while methane provides a renewable energy source.
The project integrates biotechnology, crystallization, and process engineering to examine the connection between nutrient recovery and energy production. This project focuses on investigating key factors influencing CaP crystallization and methane production such as temperature and calcium to phosphorus molar ratio and analyzing their interactions to optimize system efficiency. This project offers students the opportunity to gain practical skills in advanced analytics, bioreactor operation, and innovative approaches to sustainable agricultural solutions.
