FIBER MATERIALS: OPTIMIZE COMPOSITION AND REDUCE COSTS
Why should you think about it?
- Fiber materials account for up to 50% of total production costs.
- 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.
How can we support you in this?
While maintaining or even improving paper quality:
- Optimization of fiber composition.
- Increase of low-cost fiber materials usage.
- Reduction or shift of basis weight.
- Improvement of the fiber yield in fiber preparation.
- Reduction of reject quantities.
- …
STEAM: REDUCE CONSUMPTION AND COSTS
Why should you think about it?
- Steam costs are about 20% of total production costs.
- The biggest driver: steam consumption for drying paper.
- Further driver: The preparation of mass starch.
- Outdated steam application technologies often work inefficiently and consume far too much steam.
How can we support you in this?
While maintaining or even improving paper quality:
- Optimization of mechanical dewatering
To increase dry content. - Optimization of sheet formation
For an efficient thermal drying. - Patented starch cooking solution
To reduce steam consumption in starch preparation. - Steam application technologies
Optimization of existing or installation of new solutions. - …
CHEMICALS: REDUCE CONSUMPTION AND COSTS
Why should you think about it?
- Chemical costs are about 10 % of total production costs.
- Main cost drivers: wet-end starch and surface starch, followed by strength additives and other process chemicals.
- Prices and availability of starch types vary significantly.
- Lower quality of recycled fibers promotes the usage of chemicals to keep strength parameters and/or machine availability at least stable.
- Handling of chemicals is sometimes tricky.
How can we support you in this?
While maintaining or even improving paper quality:
- Optimization of sheet formation
To reduce starch and strength additives consumption. - Patented starch cooking solution
To reduce starch consumption and gain flexibility in using different starch types. - Optimization of wire and felt cleaning
To reduce the need for cleaning chemicals. - …
POWER: REDUCE CONSUMPTION AND COSTS
Why should you think about it?
- Electricity costs are about 10% of total production costs.
- Vacuum sources such as fans, pumps or blowers are major consumers of electrical energy, followed by drives and other motors.
- Vacuum is very often not on the radar of papermakers
- "it's just there". - Vacuum and friction influence the drive power required most.
How can we support you in this?
While maintaining or even improving paper quality:
- Optimization of vacuum demand
with regards to current production requirements. - Optimization of the vacuum curve
over entire wire section. - Automatic vacuum control valves
for reproducibility. - Re-engineering of vacuum pipeline system.
- Reduction of vacuum consumers and sources.
- Reduction of drive power required
e.g. through optimization or replacement of dewatering systems. - …
WATER: REDUCE CONSUMPTION AND COSTS
Why should you think about it?
- Water has always been a key issue for the paper industry, but it varies significantly from country to country.
- Within the process, different water qualities are available. The costs for these vary.
- The cost of fresh water is rising sharply in some cases.
- Climate change has an impact on the future availability of fresh water.
- The costs for wastewater treatment are on the rise.
How can we support you in this?
While maintaining or even improving paper quality:
- Reduction of fresh water consumption
and the associated wastewater volumes. - Shift between different water qualities
towards inferior qualities. - Replacement of higher water qualities
with lower qualities for selected applications. - Reduction of wastewater volumes
and the associated costs. - …
REDUCE WEB BREAKS AND BROKE TO LOWER COSTS
Why should you think about it?
- Web breaks and broke waste all previously invested resources - from materials to personnel costs.
- Web breaks lead to a quality-restricted start-up phase.
- Irregular machine operation has a negative impact on the entire production line.
- Reducing unplanned downtime leads to more production.
How can we support you in this?
While maintaining or even improving paper quality:
- Reduction of web breaks and unplanned interruptions
to save resources, achieve a high level of production and continuously produce homogeneous product quality. - Understand the root cause of web breaks
in order to avoid them in the future. - Targeted optimization of machine sections
to avoid unplanned interruptions and boost overall machine efficiency. - …
MACHINE CLOTHING: EXTEND SERVICE LIFE AND REDUCE COSTS
Why should you think about it?
- The more wires and felts are needed, the higher the costs for materials and downtime.
- Downtime costs for replacing wires and felts are often higher than the material costs.
- Each machine clothing requires a start-up time. The less often this is needed, the better is overall machine efficiency.
How can we support you in this?
While maintaining or even improving paper quality:
- Maximization of wire and felt service life
without impairing machine operation or paper quality. - Reduction of downtime for replacing machine clothing
and therefor increased overall machine availability. - …
