Together, these aspects strengthen both the environmental
pro昀椀le of the process and the long-term robustness of pulp
production.
Paper and tissue machine runnability and cleanliness
Effective deposit control is consistently linked to fewer
breaks, fewer cleaning stops, improved clothing life, and fewer sheet
defects. Experience from talc-free transitions shows that these
bene昀椀ts are realised only when talc is replaced by a well-designed
alternative rather than simply removed.
Sustainability and material ef昀椀ciency
Moving away from mineral additives can support broader
sustainability goals by reducing dependence on mineral raw
materials and improving process material ef昀椀ciency. Importantly,
talc-free does not mean “chemistry-free”; rather it means shifting
from mineral adsorption to targeted speciality chemistry that focuses
on stability, control, and removal.
When these elements are in place, talc-free production
becomes a robust, long-term solution that improves cleanliness,
runnability and product quality across pulp, paper and tissue
operations while maintaining a sustainable and safe working
environment.
Achieving this level of performance requires more than
individual products or isolated measures; it depends on a holistic
understanding of the process and a solution that is continuously
adapted to changing conditions.
Keys to successful talc-free operation
Long-term success in talc-free production depends on
several interlinked factors:
•
Speciality chemistry designed speci昀椀cally for deposit,
pitch, and stickies control.
•
A thorough pre study, combining on site and off site
work to fully understand each mill’s unique conditions.
•
Tailored solutions adapted to the speci昀椀c process, raw
materials, and operating window.
•
Appropriate measurement methods, such as BIMPics,
to monitor relevant indicators and verify performance.
•
Close collaboration between the mill and the chemical
supplier to enable continuous optimisation.
Conclusion
Moving to talc-free production is not simply a matter of
removing a mineral additive. It requires a new way of understanding
and managing extractives throughout the entire process. When
implemented correctly, a talc-free strategy can deliver signi昀椀cant
bene昀椀ts: cleaner processes, improved runnability, better product
quality and a more sustainable production environment.
At BIM Kemi, talc-free deposit control is not a single
product — it is a process concept built on deep chemical expertise,
advanced analytical tools and close collaboration with mills. By
combining early extractive control with system-wide stability
management, mills can achieve robust and sustainable performance
across pulp, paper and tissue production.
We believe that innovation is most powerful when it is
combined with deep process knowledge and close collaboration
with our customers, enabling tailored solutions that deliver stable
performance and long-term value.
