VacaturesInternship: Bio based green fertilizer production from livestock manure

WOStage32-40 uur



The agricultural sector has a large environmental impact. On a global scale, the agricultural sector is responsible for around 30% of the total greenhouse gas emissions, while eutrophication and surface water pollution are an issue on a regional scale. Nijhuis works on circular concepts to reduce this environmental impact by refining phosphorus, nitrogen, potassium and clean water from the surplus of livestock manure and producing bio based green fertilizers. The produced green minerals ensures regional balanced fertilization by dosing sufficient individual nitrogen, phosphate or potassium fertilizers for pasture land or arable crops. This will reduces the rinse of fertilizers into ground and surface water and reduces the use of the chemical fertilizers.

Goal and activities

The goal of this internship or graduation project is to develop and further optimize the Nijhuis system for nutrient recovery. During this internship assignment you will conduct a series of laboratory experiments, to support the design of new pilot plant. In addition, you will prepare an economical study including an estimation of the investment and running costs to compare the green fertilizer production to conventional fertilizers.
