Since the invention of paper in Egypt 3500 BC, when it was produced by using the papy-rus plant, paper is one of the most important consumer goods of the world. For example in Germany, the paper consumption is as high as nowhere else in the world. A German citizen wastes round about 236 kg paper per year. With the total waste of the population of the federal republic you could construct a tower of standard paper size sheets from the earth up to the top of the moon.
The pulp and paper industry produces approximately 393 million tons of paper for instance writing paper, industrial paper, pasteboard and cardboard per year. This shows how essential the product paper is. When you think about paper you normally mean writing paper, paper for newspapers or graphic papers for photography or high resolution magazines.
But paper can be used in completely different ways depending on the products: For example It is used in the building industry, car manufacturing and other industries; you need it for hygiene products like tissue papers, for car poll filters or for packages for comestibles or any other goods. Paper appears in different grammages and quality. All these products are produced on several paper machines with different breadth.
For example there are paper machines in China with a breadth of 20 meters. These plants normally fabricate only one product of one grammages and same quality. The paper mill I work at, has a machine width of only 4,90 meters. Because of this fact it is comprehensible that one has to produce many different kinds of paper in order to be able to exist on the buyer's market for a longer period of time.
This machine has a technical capacity of 220,000 tons per year and a turnover of 52 Million Euros. There are two major products produced on the PM1: testliner brown, white and plasterboard liner (grey, ivory and green).

Zusammenfassung der Kapitel (Chapter Summaries)
- First Part: Introduction to the Pulp and Paper Industry, the machines and the usability around the world. This chapter introduces the history and importance of the paper industry, highlighting its global reach and diverse applications. It also describes the various paper machines used in production, emphasizing the size and capacity of different plants.
- Second Part: Progress of fabricating the product... This chapter focuses on the specific process of fabricating testliner white, a common type of paper used in the packaging industry. It outlines the three key raw materials involved – recovered paper, water, and chemical additives – and details each step of the production process, from defibration to refining. The chapter also addresses the importance of maintaining a low reject proportion to minimize disposal costs.
