Mondi is investing €20 million to further improve the sustainability of its pulp production at the Frantschach mill in Austria. The mill, which is celebrating its 140th anniversary in 2021, has already been self-sufficient in terms of energy for many years and supplies surrounding communities and industrial companies with surplus heat from the pulp production process.“Today, the focus on sustainability and circularity puts fibre-based products, and pulp, right into the spotlight. Not only is wood a renewable resource, but we know that paper is the most widely recycled material in the world with, for example 74% of paper and 83% of paper-based packaging in Europe being recycled. Our new plant equipment will make our pulp production even more efficient and sustainable. The modernisation and expansion of the evaporation plant increases the amount of heat extracted and reduces the need for steam. It also reduces the chemical oxygen demand of the biological waste water treatment by 140 tonnes per year”, says Gottfried Joham, Managing Director of Mondi Frantschach. The decision to invest was driven by the need to make best use of wood as a primary input.
Solenis, a leading global producer of specialty chemicals, has introduced its new MicroSolSM advanced retention and drainage solutions to help printing and writing paper producers stay competitive through increased productivity and superior product offerings.
MicroSol is a revolutionary technology package that combines the company’s new patented PerForm™ SP7242 structured polymer with its uniquely structured PerForm™ MP9031 colloidal silica to give printing and writing paper producers a no-compromise solution for maximizing retention and drainage without sacrificing formation in the manufacturing process. As a result, papermakers enjoy a wider operating window that increases flexibility, improves machine efficiency and reduces operating costs.
“MicroSol builds on Solenis’ vast experience with retention and drainage aids,” said James Woodward, marketing manager, Printing and Writing – North America. “We significantly changed the retention and drainage landscape when we introduced our patented PerForm SP structured polymer in the early 2000s. Early generations of PerForm SP set the bar for first-pass ash retention. Now, with the introduction of PerForm SP7242 and our MicroSol package, Solenis is raising the bar even higher. To complement this technology, we’ve also created PerForm MP9031, a colloidal silica that adds to the retention initiated by PerForm SP yet promotes excellent drainage.”
PerForm SP molecules are highly anionic, three-dimensional structures that interact readily with cationic sites on fibers, fines and fillers in the forming paper. This structure allows the molecules to grab hold of ash and distribute it evenly to increase paper strength, retention and formation.
The PerForm MP colloidal silica offers a similar microstructure developed with attention to its size, surface area, structure, surface modification and solids content to ensure optimal performance in today’s paper machine processes. Used together, PerForm SP and PerForm MP offer a dynamic breakthrough combination that gives papermakers the ability to maximize retention and drainage without sacrificing formation.
