#31 How does chip pretreatment improve paper quality and profitability in the mechanical pulping process?
The often used saying “what you put in is what you get out” is very true when it comes to the mechanical pulping process (TMP). Good quality chips are essential for efficient and profitable production, as well as high quality paper products.
Chip pretreatment is a crucial stage in the TMP process as it sets the foundation for effective fiber separation during the refining process. With the latest ANDRITZ pretreatment technology for TMP, the PrimeMSD Impressafiner, producers can be assured of uniform chips, consistent chemical impregnation and reduced shives leading to a much more efficient process.
The PrimeMSD Impressafiner delivers superior impregnation and optimized chip maceration which leads to reduced energy consumption and smoother refining. It also provides improved fiber strength, lower refining challenges, and consistent pulp quality. With sustainability at its core, lower energy use and reduced waste generation align with environmental and operational goals.
In this podcast we talk to Ernst Kubr, Product Manager, ANDRITZ Refiners about the pretreatment of chips utilizing the PrimeMSD Impressafiner which has been designed for maximum efficiency and sustainability.

#30 What is the most simple and effective way to replace fossil fuels in the lime kiln?
An average lime kiln at a pulp mill will use up to 75 m3 of heavy oil to produce 450 t/d of burnt lime. This adds up to around 25,550 m3 of fossil fuel use per year. Some mills produce much more burnt lime, up to 1,000 t/d, which represents a significant cost in heavy oil use as well as adding to the mill’s CO2 emission penalties.
It is now possible to completely replace fossil fuel burning in the lime kiln by using the LimeBio-Powder biofuel plant from ANDRITZ which powderizes various types of biomass. The powderized biomass is then fed into the lime kiln and is burnt in exactly the same way as heavy oil.
The LimeBio-Powder biofuel plant can operate with various types of biomass including forest residues and pellets as well as waste wood and bark. Easy to install, and with a small footprint, the fully automated system can be integrated into a mill’s existing DCS’s or ANDRITZ automation and digitalization solutions.
In this podcast we talk to ANDRITZ white liquor plant experts Jari Vuorela, Product Manager and Ville Seppänen Sales Manager about the simplicity of installation and operation, and the major cost and emission benefits of the LimeBio-Powder biofuel plant.

#29 What were the challenges and solutions provided for the successful start-up of UPM’s Paso de los Toros pulp mill?
The mill is set to produce up to 2.1 million tons per year of high-quality eucalyptus pulp. It is deeply impressive that such a large production site operates unobtrusively and almost silently in the middle of Uruguayan cattle ranching country. Clearly, sustainability and protection of the environment at the mill is a No. 1 priority for UPM.
The Paso de los Toros mill is the second of UPM’s pulp mills to be built in Uruguay, the first one, Fray Bentos, was started up 15 years ago. Due to the enormous success with the Fray Bentos mill, ANDRITZ was chosen once again as a turnkey supplier for UPM's second mill.
Our podcast features insights from key figures at UPM’s Paso de los Toros mill including Marcos Battegazzore, VP of Pulp & Forestry operations, Uruguay; Federico Mantiñan, General Mill Manager; Daner Perez, Fiberline Manager; Santiago Tucci, Electrical Engineer. It also includes perspectives from ANDRITZ’s Eduardo Roubaud, Site Manager at the mill.

#28 How did ANDRITZ tackle the challenge of building two world-leading mills, pulp and tissue, side by side for Bracell?
The request from Royal Golden Eagle (RGE) owner of Bracell in Brazil was a tough one; to build the world’s largest and greenest pulp mill in the world, and then further, to build a tissue mill right next to the pulp mill located at
Lençóis Paulista, São Paulo state, Brazil.
And there was more; The pulp mill, Project STAR, would need to switch quickly between kraft and dissolving pulp as the markets demanded. ANDRITZ took on the challenge and delivered the complete scope of supply including a complete wood processing plant, the world’s largest HERB recovery boiler, two hardwood fiberlines, two pulp drying lines and the world’s largest non-condensable gas treatment system, focusing on the use of side streams in the recovery cycle.
For Project Tissue ANDRITZ delivered the complete scope of supply on an EPCC basis including four PrimeLine Tissue Machines. Project Tissue represents one of the largest of its kind in the world and is the largest order ANDRITZ has received for its tissue technology.
Listen to our podcast where we talk to Marcelo Montanhese de Lima, Tissue Project Senior Manager, Bracell, Rafael Sirtoli, Director of Operations from ANDRITZ in Brazil, and Klaus Blechinger, Vice President of Tissue, ANDRITZ to tell us about these two impressive and world leading projects.

#27 Is it possible to transform older, existing thermo mechanical pulp systems into modern showcases?
Due to the use of older technology at existing thermo mechanical (TMP) mills, production can significantly suffer with a lack of efficiency and quality in a highly competitive marketplace. Also on the horizon is the rapid decline in the availability of skilled operators. There is no-doubt that these older TMP mills have big challenges going forward.
ANDRITZ has been quick to react to these challenges with the introduction of its “topTMP” initiative which has brought together its vast experience in service and maintenance at TMP mills, along with its offering of the latest in cutting-edge technology.
Starting from the woodyard and covering the complete TMP process to the final pulp, the topTMP approach from ANDRITZ actively offers customers the opportunity to review and analyze plants and receive a detailed and comprehensive investment proposal.
In our podcast we welcome two ANDRITZ experts, Georg Hadl, Director Business Development Paper Engineered Services and Markus Pichler, Vice President, Sales & Application, Fiber. The discussion takes a deep dive into how TMP operators can transform their production efficiencies at older mills into powerful 21 Century production processes, complete with the latest in state-of-the art technology.
