Mercer Stendal starts Optimized Pulp Cooking Plant

Mercer Stendal continues investing in environmental and water protections with further improvements to its production facilities. With an investment of more than 50 million euros, this is the company’s largest optimization project to date since the start of production in 2004. Today, Mercer Stendal commissioned an important building – the optimized cooking plant. For this occasion, the Prime Minister of Saxony-Anhalt, Dr. Reiner Haseloff, visited the pulp mill in Arneburg.

The project, initiated two years ago, aims to optimize the pulp cooking process so that larger quantities of industrial wood are processed into biogenic products with fewer wastewater loads generated. In addition to improving Stendal’s environmental performance, the company hopes this will help solve the current problem of increasing damaged wood.

In the long term, this will put Mercer Stendal in a stronger position, as the movement in industry towards decarbonization and manufacturing of climate-friendly products based on better sustainability is a generational task. The current project includes further steps, such as an energy-efficient redesign of the lime kiln and added measures to safeguard the increased production level. These are important milestones in the ongoing development of the factory into a centerpiece of the industrial bioeconomy in Germany.

Mercer Stendal’s future pulp production capacity will be up to 740,000 tonnes per year. The biomass power plant at the site is one of the largest of its kind in Germany with an installed electrical capacity of 148 MW.
