Pulp and paper industry!

The pulp and paper industry comprises companies that use wood as raw material and produce pulp, paper, board and other cellulose-based products.

The industry is dominated by North American (United States and Canada), northern European (Finland, Sweden, and North-West Russia) and East Asian countries (such as China, Japan, and South Korea). Australasia and Brazil also have significant pulp and paper enterprises.

Manufacture of wood pulp:

A pulp mill is a manufacturing facility that converts wood chips or other plant fiber source into a thick fiber board which can be shipped to a paper mill for further processing. Pulp can be manufactured using mechanical, semi-chemical or fully chemical methods (kraft and sulfite processes). The finished product may be either bleached or non-bleached, depending on the customer requirements.

Preparation for pulping:

Woodchipping is the act and industry of chipping wood for pulp, but also for other processed wood products and mulch. Only the heartwood and sapwood are useful for making pulp. Bark contains relatively few useful fibres and is removed and used as fuel to provide steam for use in the pulp mill. Most pulping processes require that the wood be chipped and screened to provide uniform sized chips.
