2 Teaching methodology The subject comprises theoretical lectures and practical sessions, and exercise, problem and practical case solving. TM1. Participative lectures on theoretical and practical contents. TM2. Practical seminar where the teachers, with students' help, are to solve exercises and problems related to the theoretical contents of the subject. TM3. Practical sessions where the teachers, with students' help, are to solve practical cases related to the theoretical contents of the subject. TM4. Guided laboratory work or workshop tasks. TM5. Self work on the subject assignments. Learning objectives of the subject - To learn the environmental impact of pulp manufacturing processes and the principles to be adhered to in selecting the most suitable technologies available for this purpose. - To learn TCF bleaching processes, the reagents they use and their mechanisms of action, as well as the best application conditions for the particular objectives. Because the bleaching operation produces contaminants, students should also learn how to minimize their environmental impact.
