Then it is delivered to a paper mill. Where it is prepared for de-inking. In de-inking, paddles beat the paper to pulp and remove old ink, glue and staples. Heated drying rollers which squeeze water out of the pulp and dry it into new paper and cardboard. Who use it to make new products.
Paper is one of the most important and useful materials man has ever created.
Until just over a hundred years ago, most sheets of paper in the world were made by hand. And it was mostly used for precious documents. Wasps taught us how to make paper. Wasps chew fibres and weeds into a kind of paste or mash, spit it out to form the walls and chambers of their hive, and when it dries it is a kind of paper sculpture. In the 6th century when the Chinese lost to the Arabs at the Battle of Samarkand, captured paper makers were forced to share their craft with their new masters.
