BBE 4305W Pulp and Paper Technology (3 credits)
| Catalog Description: |
Course is targeted towards Paper Science and Engineering
Students at the Junior level. Class is also suggested for
students interested in Paper Science and Engineering “minor” or
in overview of pulp and paper manufacture.
BP 4305 is an introduction to the technology of pulp
and paper manufacture, intended to provide a basic foundation
in this field. Terminology and key parameters are introduced.
Stepwise description of processes from harvesting of
trees to the final product. The course includes topics
such as chemical addition to papermaking and processes
such as coating and calendaring. Other related topics,
for example recycling of papers are incorporated. The
lab section includes basic paper testing, recycled fiber
pulping and ink removal, fines retention, dry strength
addition.
The class is a “writing intensive” course.
2 technical lab reports have to be submitted individually.
They will be returned with suggested corrections and
can be resubmitted. Grading for reports will be based
on writing as well as technical content.

Overview
Pulp and Paper Technology, an important credit course from
the University of Minnesota, will be available as an online course.
There are no classroom meetings, so students can take this course
from any location that has Web access and never need to travel
to a campus or study center. Study times are flexible because you
can participate in the Web course at any time of day.
This general overview course is especially for working adults
interested in production of papermaking fiber, paper manufacture,
and paper properties. Technical personnel in the paper, printing,
or packaging industries who don't have a degree in Paper Science
and Engineering would benefit from this course. Any interested
person may register.
Professor Ulrike
Tschirner from the U of M's Department of Bio-based Products
is putting her course notes, discussions, and quizzes online
and providing videotaped labs. You do weekly assignments and
keep in touch with your professor and classmates using a class
Web site.
Course administration by Independent
and Distance Learning (IDL), College of Continuing Education,
