Study contents

The core of the Biomass Refining major is in the deep understanding of biomass and its components on microscopic and molecular levels. The core compulsory courses in the first year lay a strong scientific foundation upon which the students will further develop their knowledge of common biomass conversion processes.

The Biomass Refining major applies knowledge of the fields of chemistry, chemical and process engineering, and biotechnology. Students can choose between two specialisation pathways, one in pulp and fibres and another in fuels and chemicals.


Many of the courses are organised in co-operation with industry, and thus the topics usually deal with present-day phenomena and current challenges. For example, the new wood-based textile fiber technology is a growing field of research. Rated as one of the most carbon-polluting industries in the world, the textile market urgently needs alternative production methods. The Department of Bioproducts and Biosystems is currently piloting a production facility for cellulose-based textile fibre. In addition to textiles, the wood material science and technology offers many fascinating opportunities for students interested in research and development of new sustainable and diverse wood products.

In the major, students have the opportunity to delve deeper in their areas of interests that are listed, but not limited to course examples, below:

  • Sustainability in Bioproduct Industry (5 ECTS)
  • Biomass Pretreatment and Fractionation (5 ECTS)
  • Bioproduct Mill Recovery Processes (5 ECTS)
  • Thermochemical Energy Conversion (5 ECTS)
  • Planning and Execution of a Biorefinery Investment Project (5 ECTS)
  • Plant Biomass (5 ECTS)


Students benefit from a highly innovative and interactive learning environment at the intersection of research and industry co-operation. A key focus area is to provide industry-ready students with advanced career management skills. For example, in different project courses students will acquire experience in an engineer’s work at a consultancy company, as well as work with real-life tools for project planning. In addition, different group work assignments develop students’ interpersonal skills and prepare them to work in multidisciplinary teams in their future careers.

Personal Study Plan (PSP)

The Personal Study Plan (PSP) is a practical tool to define a student’s own study path, compiling an optimal selection of courses that are aligned with the student's interests and programme requirements. PSP is also a useful tool for students to keep track of their studies. At best, it shows where students are with their studies and sets concrete milestones for them to follow.
