On March 5, 2010 the Propapier PM2 company started up paper production in the paper plant that was newly built on green fields in Brandenburg province. The Metso company supplied the new OptiConcept Paper machine PM2 that produces 650,000 tonnes/yr test liner and corrugated material. An equally highly modern Metso pulp producing facility prepares stock made up of 100% waste paper for this world scale paper machine to make corrugated paper or board. Process, operation, and quality are controlled by a comprehensive automated system. After complying with all formal legal, technical, and environmental requirements, in August 2008 the construction and operation of this paper line were given the green light. The foundation stone and first cut of the spade were celebrated in December 2008. The construction progressed like clockwork and the assembly of the principal components by Metso began according to plan in July 2009. Metso and Propapier PM2 companies have a contract of cooperation in which Metso personnel aid in the startup of the paper machine PM2 on site for its optimum operation. The discussion covers technology and service hand in hand from the synergy service provider; overview of the data for stock preparation and PM2; cleaner and more reliable raw material for the high efficiency PM2 machine; stock preparation; largest dissolving drum at about 60 m long and 5 m dia; stock dissolution with the OptiSlush dissolving drum; high consistency cleaning and rough classification; forward cleaning, fractionating, and fine classification; OptiFeed approach flow; gap former design for maximum use of the potential of the raw material; OptiPress press section - no open drawings allowed; one row dry section with OptiDry horizontal to control the inclination tendency of the roll; surface strength application for the ultimate strength of the web; OptReel plus pope roller; a WinDrum Pro high performance roll cutter keeps pace with the PM; filtrate water treatment with the OptyCycle W ultrafiltration; comprehensive automation package; energy efficiency at the focal point of the operator or controller; use and trust, cooperation contract; and Metso project in the time table.

The European paper industry has changed in recent years. The present economic situation further influences this trend. The demands on manufactured products, machines, and facilities must adjust to this new market situation. Increasing energy costs, fluctuating raw material prices, and increasingly poorer raw material quality (waste paper) are only three of many factors to be considered. In the treatment of waste paper the paper and paperboard manufacturer seeks increasingly better systems for quality optimization and reduced energy use. Sorting is one the most important tools that considerably influences the quality. There is coarse sorting, fine sorting, and machine sorting. The discussion covers coarse sorting. Coarse sorting has the task to remove coarse impurities such as stickys and impurities from the dissolved fiber and to protect the downstream equipment. Discussion topics include efficient coarse sorting; saving energy with the OptiScreen ProCS; an example from practice of reducing energy and saving costs with increased capacity and good material quality; and summary. The Metso Optiscreen ProCS sorter opens new opportunities in coarse sorting. It enables the user to maximize stickys reduction at the start of the treatment process. Impurities and disturbing materials are not reduced in size by the gentle sorting principle and so the sorting is efficient. Stickys separation up to 75% in the OCC material are possible. The principle of the rotating screen basket guarantees less energy use at maximum sorting performance. The use of the aperture sieve baskets with large open surfaces enables acceptable passage speeds and high throughput quantities at up to 35% increased output. A worthwhile combination of coarse and fine sorting guarantees further optimization in quality and energy.

A discussion covers the use of natural resources advisedly and sustainably to maintain an efficient and cost effective manufacture of paper and paperboard. Topics include introduction; three-pillar model of the sustainability; paper as a model for sustainability; use of electrical energy; steam use; fresh water use; distribution of the research and development costs of a paper machine manufacturer; whether the paper machine of the future is a vision; and whether the paper industry is a model for sustainability. For over 2,000 years the theme of sustainability was scarcely considered. Man took what he needed from nature without looking back. Today a change in thinking has occurred. The paper industry because of its need for raw material and energy has been driven to high efficiency. Today it has the opportunity technologically and commercially to play a special role. Under natural circumstances the land area of Germany would be about all covered with forests but today the wooded area has been reduced to about one third, all due to human activity. An initial scarcity of wood began at the start of the 17 th century Large amounts of wood were needed in private houses and in the beginnings of industry. This involved glass, leather, and carbon black manufacture, and mining. Large amounts of wood were exported from the Black Forest to The Netherlands for shipbuilding. By the end of the 18 th century wood became so scarce that in winter objects and stairs made of wood were used for heating. This led to the creation of forestry science.
