Pulp is prepared by separating cellulose fibers from wood, fiber crops or waste paper. This could be done chemically or mechanically. Pulp is then bleached and dried to get the actual paper. The resulting paper is then finished according to the end use. Papermaking process is very old which was first invented in China in second century A.D. reaching Europe by 12th century. The machines have been developed over the passage of time because of which the process is faster and productivity is higher but the basic process of papermaking is still the same. Pulp and paper industry is lately controlled by North American, North European (Finland, Sweden and North-West Russia) and East Asian (China, Japan, South Korea) countries.
