Forest industries are those which are dependent on the materials that are derived from the forestry. Paper, rubber and resin industries are dependant on forests for their raw material. But the raw material for aluminium is bauxite which is found in the earth's crust.

Although raw materials for paper are available in the forests, it is not very easily procured. Paper mills are generally established near forests where bamboo and other soft wood trees are available.

There are three main stages in paper production, from when the timber arrives at the mill as a raw material right up to the stage when it becomes the final packaged product.

Paper mills are generally established near forests where bamboo and other soft wood trees are available. Paper mills engage contractors to supply bamboo and other raw materials. Due to excessive cutting in the past, there are no bamboos available in forests near the paper mills now.

Paper mills generally use wood from bamboo, eucalyptus and subabul trees. Subabul wood is most widely used now. Besides wood, a large number of chemicals such as common salt, caustic soda and so on are also used in different stages of paper making.
