| Grading: |
Grading base: Students will be required to work in teams
of up to 3. Each student will be required to submit one
(individual) lab report summarizing the lab exercises 3,
4, 5 &6. All other lab exercises will require completion
of a 1-2 page work-sheet. Students will be graded based
on
lab report (35%),
work sheets (20%),
participation, including performance in team (15%)
open book final examination (30%)
Graduate Credit: Students taking the course for graduate
credit will be required to answer additional questions
in exams and/or graduate student project

Course Content
15 lab sections including short introductory lectures
- Particle Size Distribution Testing and Analysis (Pulp
fiber analysis :Kajaani Fiber Analyzer, Bauer McNett Fiber Analyzer,
Britt Jar fines analysis; Wood chips: characterization of chip
size by length and thickness
Characterization of different pulp types (GW fiber and Kraft pulps) using
all three tests. Chip size separation based on wood chip size and on thickness.
Discussion of size distribution, comparison of the different methods, including
advantages/disadvantages and effects on different processes. (3 lab sections
- Mechanical treatments, beating and refining of chemical
pulps.
Beating of bleached chemical softwood pulp using PFI mill. Characterization
of energy input versus beating response. Introduction on refining of paper
stock in mill environment (2 lab section)
- Filtration (Handsheet formation, Drainage
rate, Canadian standard freeness)
Material from #2 o be used to determine CSF, form handsheet and determination
of drainage rate. Discussion on impact of fiber size and degree of beating
on filtration behavior of material. (2 lab section)
- Optical Property testing
Material from #3 and wood samples with different color tints to be used for
optical properties testing (Brightness, Opacity, Gloss, Scattering/absorption
coefficient, Color, definition of color color matching) (1 lab section)
- Mechanical property testing
Physical testing of various bio-based materials, wood, paper, composites
PLA etc.
- Effluent characterization (COD/BOD/TSS/TDS/AOX
if possible)
Characterization of Chemical and Biological oxygen demand for actual mill
effluent (recycled fiber mill). Determination of Total Dissolved Solids and
Total Suspended Solids. Discussion on fluctuation in effluent discharge on
performance of effluent plant.
- Bioprocessing (3 lab sections).
Enzymatic saccharification of cellulose (or pulp). Fermentation (to ethanol)
of glucose as feedstock. Processes will be performed in Gortner Lab (Biotechnology
Institute).
