Department of Forest Biomaterials

Sustainable, renewable forest biomaterials such as wood, paper and value-added biomaterials are produced by large and small industries across North Carolina, and throughout the US. These renewable biomaterials are used for construction of sustainable housing, low carbon bioenergy, recyclable pulp and paper products, and value-added chemicals and composites. The future is bright for students with a blend of engineering, materials science, and practical business skills that are highly valued by employers.

The Department of Forest Biomaterials offers two curricula leading to Bachelor of Science degrees - Paper Science and Engineering, and Sustainable Materials and Technology. Both curricula feature small classes, extensive interactions between faculty and students, opportunities for internships, co-ops and undergraduate research, and stress the professional development of all students. Graduates are exceptionally well prepared for rewarding professional careers with large or small companies in the renewable biomaterials industries, suppliers to the industry, or with government agencies.

Curricula in Paper Science and Engineering

M. V. Byrd, Director of Undergraduate Programs

The Paper Science and Engineering curriculum prepares students for careers in the paper industry, which ranks as the fifth-largest manufacturing industry in the United States. Science, engineering, and mathematics form the basis for a multidisciplinary approach to understanding the fundamental aspects of materials science and engineering of these complex renewable materials. Students study the technology and engineering of wood pulping processes, chemical and energy recovery systems, and pulp bleaching. In addition, various papermaking operations, such as refining, sizing, coating, and drying are studied. These topics, along with the chemical and biological modification of wood, papermaking, and the physics of paper based materials form a fundamental set of core courses that all students in the curriculum take.

Two concentrations are available emphasizing the different engineering aspects of pulping and paper making. The Paper Science and Engineering concentration provides an extensive background in the pulp and paper manufacturing processes and elective credit hours for studies in chemistry, marketing, economics, management or other areas of interest to the student. Greater depth in general chemical engineering principles can be obtained from the Chemical Engineering Concentration. Students who have completed the Chemical Engineering Concentration in Paper Science and Engineering can, in cooperation with the College of Engineering and with an additional semester of study, earn a Bachelor of Science in Chemical Engineering as a second degree.

The curriculum requirements for the degree in Paper Science and Engineering may be found at this link:  https://oucc.dasa.ncsu.edu/cnr-15psebs-nosubplan-2131/

Program Educational Objectives

Within a few years after graduation, alumni of the Paper Science & Engineering Program at NC State University will be:

  • Effective engineers and leaders in the paper, chemical process, and related industries.
  • Professionals who act in a safe and ethical manner.
  • Lifelong learners who pursue opportunities to continue their education.

Opportunities

Graduates of this curriculum find opportunities for challenging careers as process engineers, product development engineers, process control engineers, chemists, technical service engineers, quality control supervisors, and production supervisors. Design and construction engineering companies employ graduates as project engineers, and pulp and paper machinery/chemical companies use their education and skills for technical service and sales positions. Opportunities for managerial and executive positions are available to graduates as they gain experience.

The broad and intensive nature of this curriculum makes graduates attractive not only to the pulp and paper industry, but also to a variety of other major chemical process and bio-energy industries. This appeal is especially true for the dual degree in Paper Science & Engineering and Chemical Engineering.

Summer Internship

All Paper Science and Engineering majors are required to work one summer in a pulp or paper manufacturing facility. One hour of academic credit is granted after completion of 12 weeks of this work and presentation of an engineering report of professional quality. In addition, students are urged to work in manufacturing facilities the other two summers, as the work provides valuable practical experience. Departmental advisers assist students in locating summer jobs, which are found throughout the US and abroad.

Many Paper Science & Engineering students work at least one co-op rotation, in which they leave school for one semester and work in the industry. The resulting experience adds significantly to a student’s desirability upon graduation.

Accredited Program

The Paper Science and Engineering program is accredited by the Engineering Accreditation Commission of ABET, http://www.abet.org.

Regional Program

The Paper Science and Engineering curriculum is a regional program approved by the Southern Regional Education Board as the undergraduate program to serve the Southeast in this field.

Scholarships

Approximately 125 undergraduate academic scholarships worth approximately $300,000 are granted annually to new and continuing students by companies comprising the Pulp and Paper Foundation, and by alumni and supporters of the program.

Minor in Paper Science and Engineering

The Paper Science and Engineering Minor is available to all undergraduate students enrolled in the university as degree candidates except Paper Science and Engineering Majors. The minor requires 15 credit hours. Six hours of required courses provide a comprehensive overview of pulping and paper making science and technology, including pulping, bleaching, chemical recovery, recycled fibers, paper making, coating, printing, converting, and paper properties. Nine elective hours may be chosen from areas including wood chemistry, wet end chemistry, unit operations, process design and analysis, project management, and process control.

The course requirements for the PSE minor may be found at this link:  https://oucc.dasa.ncsu.edu/pulp-and-paper-technology-15ppm/

The Paper Science and Engineering Minor, with its focus on paper making science and technology, is intended to be especially valuable to students majoring in programs leading to careers in corporate or government positions which would interface with the paper and related industries. Students interested in business, scientific or engineering specialties which may interface with or are employed by these industries will find the minor especially useful.

Admissions and Certification of Minor

All undergraduate students enrolled in the university as a degree candidate, other than PSE majors, are eligible for admission to the PSE minor program. The PSE Minor Adviser will serve as adviser and certify completion of the minor. Paperwork for certification must be submitted to the minor adviser no later than the registration period for the student’s final semester at NC State.

The minor must be completed no later than the semester in which the student expects to graduate from his or her degree program.
