Wood Processing

Wood processing is an engineering discipline comprising the production of forest products, such as pulp and paper, construction materials, and tall oil. Paper engineering is a subfield of wood processing.

Paper engineering

Paper Science & Engineering (also called Bioprocess Engineering, Chemical Engineering and/or Biochemical Engineering) is a branch of engineering that deals with the application of physical science (e.g. chemistry and physics) and life sciences (e.g. biology and biochemistry) with mathematics to the process of converting renewable raw materials into useful and valuable products. The field employs the principles of process engineering and unit operations to the manufacture of paper, chemicals, energy and related materials. The following timeline shows some of the key steps in the development of the science of chemical and bioprocess engineering.

From a heritage perspective, the field encompasses the design and analysis of a wide variety of thermal, chemical and biochemical unit operations employed in the manufacture of pulp and paper; addressing the preparation of its raw materials from trees or other natural resources via a pulping process, chemical and mechanical pretreatment of these recovered biopolymer (e.g. principally, although not solely, cellulose-based) fibers in a fluid suspension, the high-speed forming and initial dewatering of a non-woven web, the development of bulk sheet properties via control of energy and mass transfer operations, as well as post-treatment of the sheet with coating, calendering, and other chemical and mechanical processes.

Applications

Today, the field of Paper & Chemical Engineering is applied to the manufacture of a wide variety of products. The (bio) chemical industry scope manufactures organic and agrochemicals (fertilizers, insecticides, herbicides), oleochemicals, fragrances and flavors, food, feed, pharmaceuticals, nutraceuticals, chemicals, polymers and power from biological materials.

Typical products in wood processing are:

From Pulp

* Caftliner

* Cellulose

* Paper,

As Engineered Wood

* Plywood

* MDF

* Oriented strand board

As Chemicals

* Tar

* Tall oil

* Wood fuel

* Phenoles

* Pinenes

* Pine soap

As Timber

* Of residuals from timber processing or as first step of mass processing

* Wood chips

* Bark chips

* Wood pellets

* Wood shavings
