history

On September 16, 1912, Johann Rieger's company, the "Johann Rieger Pappenfabrik", started production in Trostberg. The board factory started out on a small scale. With a workforce of around 100, six tons of hand leather and hand wood cardboard were produced per day. The demand for cardboard grew steadily. The machines turned out to be insufficient and had to be replaced with more powerful machines. In 1925, board machine 1 (KM1) with four cylinder molds and ten drying cylinders was finally put into operation.

With the great fire in 1926 and the destruction of large parts of the factory, Johann Rieger decided to modernize the factory: drying tunnel instead of air drying, new boiler house, coal instead of peat, superheated steam single-cylinder machine, one-meter grinder. The products also changed. While the production of handboard became less and less important, Rieger relied on white cardboard, which promised permanent sales. After the Second World War and with the economic boom, the Rieger company was able to focus on increasing production. A series of significant investments made it possible to almost double production (and also sales) in ten years: to 40 tonnes per day.

After Johann Rieger's death in 1967, his sons Ernst and Hans Rieger took over the management of the factory until 1989. After that, the era of the Rieger family business as a cardboard and later as a cardboard factory ended after three generations. Thomas Prinzhorn , owner of W. Hamburger AG (after the founder W. Hamburger) from Pitten in Lower Austria, was ready to continue the factory in the spirit of Rieger. Thomas Prinzhorn already represents the 5th generation of the Hamburger family. On July 17, 1989, the traditional Austrian company took over the Rieger cardboard factory.

Thomas Prinzhorn continued to invest in the Trostberg company. On February 15, 1992, the project “Conversion of PM2 ” began as planned . From the existing cylinder mold KM2 with 28,000 tons per year the Fourdrinier machine PM2 with 65,000 tons per year was to be created: a special machine for the production of four-ply, high-quality, white-covered and coated cover papers based on waste paper. Over 500 fitters from a wide variety of suppliers were necessary to complete the conversion in just eight weeks. The aim of this rebuilding measure was the market launch of white corrugated base paper. Hamburger Rieger relied not only on modern machines, but also on the ecological aspect of paper production. In June 1997 the new aerobic / anaerobic wastewater treatment went into operation. Around DM 5.7 million will be invested in the clean Alz .

In 2000, Rieger celebrated its highest production output to date with 112,000 tons per year. And with the renaming from “Kartonfabrik” to “Papierfabrik” on January 1, 2001, Rieger also made its product focus, which was now paper production, clear to the outside world. In 2002 the PM2 was equipped with a shoe press and a transfer belt.

In 2002 the decision was made to start a new PM project. Spremberg (Brandenburg) in the Schwarze Pump industrial park was chosen as the location . Here was the paper machine 1 (PM1) in three years of planning and construction. The machine went into operation on April 7, 2005.

In 2010 the merger of Hamburger Rieger and Hamburger Spremberg took place in order to further increase competitiveness. Joint developments and optimizations of the products, a joint market presence and a joint, broad product range were the focus of the merger.

In October 2011 the combined cycle power plant in Trostberg was put into operation. The gas turbine generates around 7 MW of electrical power. Together with the existing steam turbine, which was inaugurated in August 2007, around 8 MWel are generated. This corresponds to around 70% of the paper mill's electricity needs.

The RDF power plant went into operation in December 2012 . More than 250,000 tons of fuel are processed annually.

In 2012 the Hamburger Rieger celebrated its 100th anniversary.

In 2014 Hamburger Rieger Gelsenkirchen GmbH & Co. KG was integrated into the Prinzhorn Group.

Since July 2015, all sales transactions have been handled by Hamburger Containerboard GmbH.

Paper and cardboard manufacture

A paper mill is basically divided into three plant areas that are necessary for the production of paper. The production process begins with stock preparation. Here, the raw materials delivered in the form of dry bales, waste paper and / or cellulose, are dissolved with a lot of water and freed from impurities. In a second step, the paper machine takes over the prepared pulp suspension and turns it into an endless paper web. Finally, the paper is put together customer-specifically in the equipment. The paper is cut to the required length and width before delivery.
