Boelo Schuur is Professor Separation Technology in the cluster Process & Catalysis Engineering. Key research field is sustainable separation engineering, including both development of new and innovative, more sustainable separation processes for existing chemical operations, and enabling completely new separations. In that last category, biorefinery applications and circular economy applications are key topics. This includes recovery of volatile fatty acids from fermented waste water and downstream conversion into high value chemicals, extraction of lipids from microalgae, and downstream fractionation of pyrolysis oils. In several occasions, the use of innovative technologies such as stimuli responsive materials for smart separations helps making these complex separations possible and more sustainable.

Also in teaching, Boelo Schuur is involved in sustainability. He teaches BSc courses on industrial chemistry and processes, and a project sustainable chemical industry. Furthermore he teaches the MSc course advanced molecular separations.

Separation technologist working as tenured associate professor with a main focus on affinity fluid separations. The two main research lines are
a )    Development of new separations for (bio)refineries, e.g. recovery of volatile fatty acids from fermented wastewater, extraction of lipids from microalgae, and fractionation of pyrolytic oils, but also improving the energy efficiency in petrochemical separation challenges.
b)    Study on intermolecular interactions in affinity separations, aiming at better understanding the thermodynamics of these interactions in order to optimize the balance between high affinity in the primary separation and lower affinity in the secondary separation (i.e. through change in conditions, or even through the use of stimuli responsive separating agents).

Currently, he works with 6 PhD-students on these two lines. The scientific output(October 2017), see appendix for full list of papers) includes 72 peer reviewed journal papers, 2 book chapters, 11 peer reviewed conference proceedings and 14 patents from 4 patent families.
