Wood Scientist
Wood science is a material science in which the physical, chemical and biological properties of wood are studied.

Wood scientists apply the knowledge gained from their studies to develop and improve technologies for processing wood into pulp, paper, building and construction timber, chip and fibreboard and laminated beams. Wood scientists may work in a wood processing plant (pulp and paper), sawmill or furniture and board factories.

They often end up working in research, management, administration, process development, materials engineering, quality control, manufacturing, production, marketing or sales.

Some areas of specialization for wood scientists include:

- New fibre sources: research focuses on using sisal as a cheaper alternative to glass fibre in reinforced plastics. TMP/CTMP pulping properties of new Pine species are carried out

- Biopulping studies: pulp evaluation of different Pine and Eucalyptus species. Chipping, chip screening, Kraft cooking and testing of pulp strength properties according to Tappi standards

- Utilisation of various industrial by-products: a number of industrial by-products are used to develop new types of mineral bonded fibre and plastic / plastic composite materials to be used as building components

- Kaolin: research to upgrade locally beneficiated kaolin for coating applications. Print quality evaluations of coated paper by image analytical techniques are carried out.

- Handmade paper: expertise on all aspects of handmade paper production

- On-line control of chemical additives in papermaking: development of process control loops to monitor wet end chemistry during stock preparation and sheet formation. Control over added chemicals will minimize process variability and improve product uniformity.

- Durability testing of exterior surface finishes on wood: the performance of various coating systems is tested under natural exposure and artificial weathering conditions in the laboratory

- Wood drying: development of new kiln designs and construction materials; optimal drying control using discrete on-line mathematical models of moisture movement; development of new methods of wood moisture measurement above fibre saturation point

- Solar drying. non-conventional kiln design.

- Drying schedule development, includes chemical analysis of wood: quantitative chemical wood analysis; wood preservation: study of factors degrading wood, methods of treatment and test methods

Satisfying Aspects
- working with a natural product
- variety of specializations to choose from
- good job opportunities
- good remuneration possibilities

Demanding aspects
- working with uncooperative staff
- sometimes working in noisy or dust filled environments

Requirements
A wood scientist should:
- have an aptitude for Mathematics and Physical Science;
- be interested in technology;
- think creatively;
- have organisational abilities;
- have good interpersonal and communication skills.

School Subjects
National Senior Certificate meeting degree requirements for a degree course
National Senior Certificate meeting diploma requirements for a diploma course

Each institution will have its own minimum entry requirements.

Compulsory Subjects: Mathematics, Physical Sciences
Recommended Subjects: Engineering and Technology

Training
Degree: BSc Wood Science - US or one can follow a BEng (Chemical Engineering) with special emphasis on pulp and paper subjects from the third year.
Wood Technology - NMMU

Employer
Wood scientists, in mechanical processing, are employed by:

- saw mills
- factories (plywood, chipboard, fibreboard, laminated beams)
- furniture factories

Wood scientists, specialized in chemical processing, are employed by:

- pulp and paper industries

There are also good career opportunities for wood scientists in the research field and in their own enterprises. As wood scientists' skills are highly specialized they can work as consultants to large corporations. They can also set up companies that process wood for the purpose of timber construction.
