Optimize fiber composition
Why should you think about it?
- The proportion of total production costs accounted for by fibers is considerable.
- The costs and availability of raw materials vary - sometimes greatly.
- High-quality raw materials should be used as selectively as possible.
- The raw material quality of waste paper is continuously decreasing.
How can we support you in this?
While maintaining or even improving product quality:
- Shift in the composition of raw materials.
- If possible, in the direction of lower-quality, more sustainable raw materials.
- Reduction or shift of basis weight.
- Improvement of the fiber yield in fiber preparation and thus a reduction in reject quantities.
Reduce steam consumption
Why should you think about it?
- Thermal energy consumption accounts for a large proportion of production costs.
- Steam consumption for drying paper is enormous and the biggest driver.
- A considerable amount of steam is also required for the preparation of mass starch.
- Steam application technologies are also significant steam consumers. Outdated steam boxes often work inefficiently and consume far too much steam.
How can we support you in this?
While maintaining or even improving product quality:
- Reduction of steam consumption for drying paper:
- Dry content increase in mechanical dewatering.
- Improvement of the sheet formation for more efficient thermal drying.
- Reduction in steam consumption for starch processing.
- Optimization of existing or installation of new steam application technologies.
Reduce chemical consumption
Why should you think about it?
- The cost of chemicals is a significant cost factor.
- The main cost drivers are mass starch and surface starch, followed by strengthening chemicals and other process chemicals.
- Lower waste paper quality promotes the use of chemicals to keep strength parameters and/or machine availability at least stable.
- The prices and availability of different types of starch vary - sometimes greatly.
- Handling chemicals is sometimes tricky.
How can we support you in this?
While maintaining or even improving product quality:
- Improvement of the formation and thus
- reduced starch consumption.
- reduced need for strength agents.
- Reduced starch consumption thanks to modern cooking processes in starch preparation.
- Flexibility in the use of different types of starch.
- Reduction of cleaning chemicals by optimizing the cleaning process for wires and felts through better conditioning.
Reduce electricity consumption
Why should you think about it?
- The electricity consumption for drives, vacuum supply and other motors is considerable.
- Vacuum sources such as fans, pumps or blowers are major consumers of electrical energy.
- Vacuum is very often not on the radar of paper manufacturers - "it's just there".
- Vacuum and friction are the drivers that influence the amount of drive power required.
How can we support you in this?
While maintaining or even improving product quality:
- Optimization of vacuum demand and adaptation to production requirements.
- Optimization of the vacuum curve over the entire wire section.
- Use of automatic valves for reproducibility.
- Re-engineering of the pipelines.
- Reduction of vacuum consumers and therefore vacuum sources.
- Reduction of needed drive power, e.g. through
- Replacement of outdated dewatering systems with modern technology.
- Optimization of dewatering foils and covers with regard to current production conditions (design, material, servicing).
Reduce water consumption
Why should you think about it?
- Water has always been a key issue for the paper industry, but it varies greatly from country to country.
- The cost of fresh water is rising sharply in some cases.
- Climate change has an impact on the future availability of fresh water.
- Different water qualities are available within the process. The costs for these vary.
- The costs for wastewater treatment are also on the rise.
How can we support you in this?
While maintaining or even improving product quality:
- Reduction in 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
Why should you think about it?
- Paper breaks waste all previously invested resources - from materials to personnel costs.
- In addition, they 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 product quality:
- Reduction of unplanned paper breaks and interruptions to save resources to
- achieve a high level of production and
- continuously produce homogeneous product quality.
- Understand the causes of paper breaks in order to avoid them in the future.
- Targeted optimization of machine sections to
- avoid unplanned interruptions and downtime,
- and boost overall machine efficiency.
Extend service life of machine clothing
Why should you think about it?
- The more machine clothing is used, the higher the costs.
- The more downtime is required to replace machine clothing, the higher the costs. The downtime costs are often higher than the material costs themselves.
- Each machine covering usually requires a certain start-up time. The less often this is necessary, the better for the overall machine efficiency.
How can we support you in this?
While maintaining or even improving product quality:
- Maximizing the running time of the machine clothing without impairing machine operation or product quality.
- Reduction in downtimes for replacing machine clothing and therefore an increase in overall availability.
