Learning Outcomes

Upon successful completion of the course, the student should:

  • Understand the basic concepts and principles of biorefinery and the circular economy.
  • Have understood the most important technologies of production of separation, recovery of useful materials from wastewater, production of biofuels 1st, 2nd and 3rd generation.
  • Be sufficiently familiar with the comparative advantages of each technology and its applications on a case-by-case basis.
  • Have been trained in performing technical calculations necessary for the sizing and design of biorefinery
  • Have understood the basic concepts of environmental technical and economic parameters by comparing costs and performance.

The skills that the student is expected to develop upon successful completion of the course are:

  • Ability to interpret the basic principles of biorefinery and circular economy.
  • Ability to carry out dimensioning and design of biorefinery systems and circular economy.
  • Ability to perform technical calculations.
  • Ability to review environmental, technical and economic parameters in biorefinery and circular economy.
