John Tate set up a mill in Hertford. Sir John Spilman (a goldsmith to Elizabeth I) – erected a paper mill at Dartford. During industrial revolution of the 18 th century the manufacturing of paper underwent a drastic change. During this time, human labour was replaced by machinery. In 1838, Charles Fenerty, from Halifax used wood pulp to make paper. In 1856, corrugated paper, commonly known as cardboard was made by the British men Healey and Allen. During that period men’s tall hats line was given by cardboards. Paper can be coloured, coated, printed and even written on it. Paper is laminated with fabric, plastic and metal.

Daily new ways are being devised for using paper and the evolution will not stop as paper is an expression of everyday living. Paper is used: Agriculture: Seed packets, fertilizers, animal feed, pesticides and insecticides sacks animal feed,

Utilization of recovered would reduce load on demand of fresh fibres. About 80% of the waste paper is used in the manufacture of paper boards. Small scale units depend almost entirely on waste paper as raw material. In developed countries use nearly 40% of recycled fibre but in India uses only 20% of the recycled paper.

Pulp production in pulp mill:

The first step to make paper is to dissolve the raw material into wood pulp (watery soup) whether it is a hard wood, soft wood or recovered paper. In order to separate the fibres, the raw material is broken down into its component elements. The pulping results in a mass of individual fibres are being produced. In order to remove any remaining fibre bundles, it is being washed and screened, the water is pressed out and the residue is dried.

The pulp is ready to use. It can be used directly to make unbleached paper or if the pulp is used for making white paper requires bleaching. As per method of production, pulp is graded and classified, Classification and grading is being done whether the pulp is produced
