Inauguration of the Mercer Lignin Center at Mercer’s Rosenthal pulp mill

• State-of-the-art Lignin Center with a capacity of 1,000 kilograms of high-quality lignin per day
• Close lignin development cooperation with universities, research institutes and other industrial companies
• Opening in the presence of Bodo Ramelow, Prime Minister of Thuringia, and Juan Carlos Bueno, CEO Mercer International

Rosenthal am Rennsteig, Germany – August 23, 2023 – In the presence of Bodo Ramelow, Prime Minister of Thuringia, and Juan Carlos Bueno, CEO of Mercer International, Mercer International Inc (“Mercer” or the “Company”) (Nasdaq: MERC) will inaugurate the Mercer Lignin Center on August 23, 2023. The state-of-the-art facility is located on Mercer Rosenthal’s site in Rosenthal am Rennsteig, Germany, and represents an important milestone in Mercer’s ongoing commitment to resource-saving innovation.

“Bioeconomy is a key success factor for the Thuringian economy. The Mercer Lignin Center shows that we are on a very good path here to strengthen the location and set an example beyond the region,” said Prime Minister Bodo Ramelow at the opening ceremony. “This also applies to the cooperative approach with the research institutions and industrial partners, which I expressly welcome.”

“Our focus is on the full utilization of wood resources. It is therefore only logical to exploit the often untapped potential of lignin,” said Juan Carlos Bueno on the background to the forward-looking investment.

The Mercer Lignin Center is a fully integrated pilot plant with a maximum capacity of 1,000 kilograms of high-quality lignin per day on an area of 1,000 square meters. It is the first facility of its kind in Germany and includes storage facilities, on-site control rooms, offices and laboratory workstations. Integration into the pulp mill ensures smooth operation and enables the production of different lignin grades.

Lignin is a by-product of the utilization of wood cellulose and consists of various aromatic building blocks, the phenylpropanoids. This is what makes the raw material so valuable, because aromatic compounds are normally obtained from petroleum. Phenylpropanoids are used to manufacture a wide variety of materials and products such as plastics, medicines or paints. Other promising applications include the production of batteries and composite materials.

With the opening of the Mercer Lignin Center and Mercer’s close cooperation with universities, research institutions and other industrial companies – from the wood-based materials industry to the battery industry – great potential is opening up for the integration of these lignin-based materials into the industrial bioeconomy, far beyond the borders of the Free State of Thuringia. In this way, Mercer actively supports the use of renewable resources in the economy as well as the desired independence away from fossil-based raw materials. The project is supported with funds from the Thüringer Aufbaubank.

“At Mercer, we support the idea of a sustainable circular economy and the responsible use of nature. Therefore, in order to optimize the use of the natural raw material components of our by-products, we are willing to overcome conventional ways of thinking and invest in new technologies,” said Juan Carlos Bueno. “The opening of the Lignin Center is another forward-looking contribution by Mercer to a strong bioindustry. We will continue on our path, investing in processes and technologies focused on continuous improvement and innovation in all areas of our business.”

Mercer Rosenthal produces kraft pulp, raw material for German and Central European paper and tissue production. The annual production capacity is 360,000 ADMTs. In addition, Mercer Rosenthal operates the largest solid biomass-based power plant in Thuringia, with a thermal capacity of more than 400 megawatts and an electrical capacity of 57 megawatts. An important biobased by-product of Mercer Rosenthal’s pulp production is tall oil, which replaces fossil products in the chemical industry. Lignin joins the existing portfolio of bioproducts from Rosenthal. 

Mercer International Inc. is a global manufacturer of wood-based products with locations in Germany, Canada, the United States and Australia. Mercer annually produces about 2.3 million tons of pulp, about 1 million cubic meters of lumber, 210,000 cubic meters of cross-laminated timber (CLT), 45,000 cubic meters of glulam, and 17 million pallets.  In addition, processed wood is used to produce biochemicals such as tall oil, turpentine, methanol, and bioenergy.
