Study Guide

Objectives (course unit)

The aim of the course is to familiarise the student with the manufacturing processes and applications of mechanical and circular fibre masses. For example, the students will learn the meaning of bulk, carbon and flotation.

Upon completion of the course, the student will
• be able to describe the structure and classification of wood fibres and know the main properties of fibres
• understand the manufacturing processes of the most common mechanical pulps and the different recycling methods
• understand the importance of the circular economy and its applications in the processing of wood fibres
• be able to describe the sizing process and the recycling process of cardboard.
