The student knows
- different methods in chemical pulping, mechanical pulping and chemi-mecanical pulping
The students learn the manufacturing of sulphate
pulp and importance of all key unit operations,
cost structures and environmental impacts. The
students will be prepared to work in a sulphate pulp
mill or other position, where these skills are needed.
- the raw-materials, production and usage of recycled pulp
- the cost structures and environmental effects of recycled pulp
- control the processes and the quality.

Basics of chemical pulping. Sulphate pulping method
and its key unit operations. Cost structure and
environmenta impacts of sulphate pulping.
