OPTIMIZE FIBER COMPOSITION

• Costs and availability of fiber materials vary – in some cases significantly.
• High-quality raw materials should be used as selectively as possible.
• The quality of recycled fiber materials is continuously decreasing.

• Optimization of fiber composition.
• Increase usage of low-cost fiber materials.
• Reduction or shift of basis weight.
• Improvement of the fiber yield in fiber preparation.
• Reduction of reject quantities.
• …

Discover how we optimize fiber composition on paper machines through targeted measures, based on our successfully implemented projects. Our case studies clearly demonstrate how you can significantly reduce your costs while maintaining or improving paper quality and achieving a return on investment starting in just a few months. 

ACHIEVED RESULTS

• Fiber composition optimized while maintaining paper quality.
• Virgin fiber replaced by recycled fiber.
• Savings in virgin fiber achieved of more than 3 %.
• Return on investment within a few months.

ACHIEVED RESULTS

• Fiber composition optimized while maintaining paper quality.
• Long-fiber pulp replaced with in-house short-fiber pulp by more than 8 % or 5,600 t per year.
• Logistics for purchased long-fiber pulp eliminated.
• Return on investment within a few months.  

ACHIEVED RESULTS

• Usage of converting broke increased by 50%.
• Virgin fiber replaced by recycled fiber.
• Refiner plate service life increased by 30%.
• Fines in the flotation reduced by 75%.
• The same or even improved paper quality.
• Return on investment within a few months.  

ACHIEVED RESULTS

• Shift in basis weight achieved due to optimization of sheet formation of top and bottom layer.
• Virgin fiber replaced by recycled fiber.
• Paper quality improved.
• B-quality and broke reduced.
• Laboratory waiting times for values such as surface, strength and sheet formation massively reduced.
• Return on investment within a few months.  

ACHIEVED RESULTS

• Reject quantities significantly reduced.
• Fiber yield improved by 980 t per year.
• Waste paper as a raw material is brought into the product and does not have to be discharged.
• Need for reject dewatering (electricity) and logistics for landfill or thermal recycling reduced.
• The same or even improved paper quality.
• Return on investment within a few months.
