During his PhD studies, Andrej Šáner researched the use of grass fiber residue from green protein production as feedstock for production of biochar. Biochar is carbonized biomass produced at elevated temperatures (above 300 °C) in absence of oxygen, in process called pyrolysis, with wide applications in agriculture and animal husbandry. Andrej Šáner studied how various species of grass and level of grass processing during the protein production affect the yields and quality resulting of grass biochar. Furthermore, biochar application in animal feed as toxin binder was explored.

The new research findings contribute to the understanding of grass feedstock pyrolysis and use of resulting biochar in animal feed.

The PhD study was completed at the Department of Animal and Veterinary Sciences, Faculty of Technical Sciences, Aarhus University.

This summary was prepared by the PhD student.
