5. Special machines
In this section, we focus on two types of machine that are unique in their technology:
the cardboard machine ;
the single-cylinder machine for "sanitary and household" papers.
These machines are unique in that the papers they manufacture are at the two ends of the grammage range: above 200 g/m 2 for cardboard and below 25 g/m 2 for "sanitary and domestic" papers.

Economic data
According to the annual Pulp and Paper International survey published in July 2002, world production in 2001 amounted to 179,374,000 tonnes of pulp and 318,147,000 tonnes of paper and board (tables 1 , 2...
Specific consumption
Paper manufacturing consumes thermal energy, particularly in the dryer, and electrical energy at all stages of the process.
Paper manufacturing also consumes water at the various stages of pulp preparation, additives and on the paper machine. Some of this water is recycled (see wet-end circuit), while the surplus is sent to the wastewater treatment plant. Finally, it generates waste (sludge,...

Standards
Numerous standards have been specially designed for the paper industry, both for the classification and quality assessment of pulp, paper and board, and for the definition of the finished product. In France, paper industry standards are either AFNOR (NF Q standards), ISO (from the ISO/TC 6 technical committee) or CEN (EN standards) (from the CEN/TC 172 technical committee).

Manufacturers. Suppliers
Given the diversity of materials and equipment used by pulp, paper and board mills, it is not possible to provide an exhaustive list of manufacturers and suppliers. For this reason, various directories have been specially published for the paper industry, bringing together all the players in the profession.
