# Paper Industry Decarbonization: How Metsä Board and Südpack Differ

*Industry Insights · 6 min read · 2026-09-18*

> Paper mills and packaging converters start their decarbonization journeys from different places. Equipment efficiency, process design, and energy use cannot be reduced to a single ESG (environmental, social, and governance) slogan.
See how Metsä Board and Südpack are approaching it, so brands can turn procurement requirements into acceptance criteria, and Taiwanese SMEs can see where their money should go first

**Quick answer:** Paper industry decarbonization takes two paths: Metsä Board is upgrading slitting equipment, while Südpack is reworking its processes and energy structure. Mai Strategy's Three-Gate Prepress Check turns the requirements into emissions, quality, and delivery criteria

## How Metsä Board and Südpack Take Different Decarbonization Paths

The two companies are taking different routes to cut emissions: Finnish board manufacturer Metsä Board is starting with equipment upgrades, while German packaging converter Südpack is starting with its processes and energy structure. The former is addressing paper-roll conversion efficiency. The latter is addressing the sources of emissions on the production floor.

Decarbonizing the paper industry means turning energy use, material waste, and supply reliability in paper production and converting into management requirements that can be tracked, improved, verified, and explained externally. If brand procurement teams only say, "I want more sustainable paper," they usually have not yet asked about slitting quality, lead-time risks, or whether downstream printing can remain stable.

Published on September 14, 2026, the [report on the equipment upgrade at Metsä Board's Kemi mill](https://www.print.de/allgemein/metsae-board-modernisiert-rollenschneider-im-werk-kemi/) makes it clear that work on the Rollenschneider, a paper-roll slitting machine that cuts jumbo rolls into specifications needed for later processing, is scheduled during the annual maintenance shutdown from October to November 2026. The goals include product quality, production efficiency, and supply reliability. Südpack, meanwhile, has announced further CO₂ reductions, focusing on process and energy-structure optimization.

## Why Metsä Board Is Starting with the Rollenschneider

Metsä Board is starting with the Rollenschneider because paper-roll slitting directly affects product specifications, material yield, and shipping schedules. Small equipment deviations can snowball into quality and delivery problems in downstream processing.

The Kemi mill has annual capacity of about 465,000 tonnes, and Metsä Board says it is the world's largest coated White-Top-Kraftliner mill. Coated White-Top-Kraftliner, kraftliner board with a white coating on the surface used as the outer liner of corrugated boxes, is then sent to converters around the world. Paper-roll slitting is not the most visible step, but it often determines whether downstream operators have to stop the line and wait for material.

The project schedule also reveals how the investment is being managed. Metsä Board has placed the equipment upgrade in the annual maintenance shutdown from October to November 2026, putting construction work and supply planning into the same plan. I read this investment as an indirect decarbonization measure. Once efficiency and yield improve, waste and rework per unit of deliverable product could fall. But the public information gives no percentage reduction in CO₂, so brands must not treat annual production capacity as a decarbonization result.

## Why Südpack Is Addressing Processes and Energy Together

Südpack is treating processes and the energy structure as one improvement area because emissions from packaging converting shift along with process planning, equipment loads, and the way energy is used.

Südpack has announced further CO₂ reductions. At this stage, the directions we can confirm are process optimization and changes to the energy structure. Without a published specific energy initiative or reduction percentage, we should not fill in details such as switching fuels or changing the electricity supply. Any sustainability claim a brand receives must be traceable back to the actual process for verification.

On factory floors, I often see teams switch to a more environmentally friendly paper stock without checking printing, lamination, drying, changeovers, and idle energy use at the same time. When rework piles up, materials and energy are still consumed again and again. Südpack's case offers Taiwanese manufacturers a clear reminder: trace emissions through the process first, then decide how to adjust the energy mix. That is how decarbonization reaches the daily production record.

## Should Taiwanese SMEs Upgrade Equipment First or Rework Their Processes?

Taiwanese SMEs should start with the steps that most often cause waste, downtime, or wasted energy and that can be recorded. If slitting quality is the bottleneck, assess equipment upgrades first. If emissions are spread across several stages, start by reworking the process.

Don't rush.

The Metsä Board and Südpack cases can be turned into a three-step decision process:

・1. Map the process first: mark waste, rework, idle time, and delivery irregularities from incoming materials through slitting, printing, converting, and shipping

・2. Match the path: for a slitting bottleneck, look at equipment efficiency and yield. For emissions across multiple stages, look at process handoffs and energy allocation

・3. Sequence the work: use the Kemi example as a reference, with work carried out during the October to November 2026 maintenance shutdown. Schedule the retrofit around the maintenance window and backup supply arrangements.

An equipment investment without measurement indicators leaves only a new machine. Process optimization without quality and delivery records gives brand procurement teams little reason to trust the result.

## How Brand Customers Can Put Paper-Industry Decarbonization into Procurement Requirements

Brand customers should turn paper-industry decarbonization into manufacturing requirements that can be verified. They should ask suppliers to spell out which step is being improved, the measurement boundary, the timeline, and whether paper quality or delivery has been affected.

Start with one batch.

I suggest putting the requirements into the "Mai Strategy Three-Gate Prepress Check."

・1. Make clear where the emissions reduction happens: equipment efficiency, material waste, process flow, or the energy structure. "More environmentally friendly" cannot be used to cover every answer.

・2. Check the delivery results: include product specifications, print quality, converting stability, and lead time in the acceptance checks. The Metsä Board Kemi case puts quality, production efficiency, and supply reliability in the same equipment investment.

・3. Keep a traceable record: state the before-and-after periods, measurement scope, and evidence. If there is no CO₂ reduction figure, do not add a percentage yourself.

The Kemi mill's roughly 465,000-tonne annual capacity reminds brands that supply stability is part of procurement value. When missed delivery dates cause reprints, order changes, or air freight, the cost and communication risk come back to the brand. If a brand wants to turn these requirements into paper, printing, and delivery specifications, it can ask MINDS to start with a prepress review for fully customized, mid- to high-end commercial printing.

## Key Takeaways

・Metsä Board is starting with slitting equipment. Its decarbonization logic runs through efficiency, yield, and supply reliability

・Südpack is treating processes and the energy structure together. Changing materials cannot replace process management

・Taiwanese SMEs should find the stages with the most concentrated waste, downtime, or energy use before choosing where to invest

・Brand procurement should verify emissions evidence, product quality, and delivery results together

## Further Considerations

On the print manufacturing side, start by keeping records for paper stock, slitting, printing, converting, and delivery. On the design side, confirm manufacturability when choosing paper and developing the structure. AI (artificial intelligence) and SaaS (software delivered online through a subscription) are useful for organizing batch data, comparing supplier documents, and flagging anomalies. They cannot replace human judgment when it comes to standing behind CO₂ results. If a brand wants to turn this framework into cross-functional specifications, it can ask the [Mai Strategy Knowledge Academy advisory team](https://mindsprt.dev) to help sort out the questions, evidence, and ESG messaging. The next step is to run one frequently produced item through the full cycle, then expand to other products.

## FAQ

### How do Metsä Board and Südpack differ in their approaches to decarbonization?

Metsä Board is starting with a Rollenschneider equipment upgrade at its Kemi mill in Finland to improve production efficiency and supply reliability. Südpack is focusing on process and energy-structure optimization. The former is about equipment efficiency, while the latter is about how manufacturing is managed.

### What is a Rollenschneider, and why does it affect paper-industry decarbonization?

A Rollenschneider is a machine that slits jumbo paper rolls into specifications for downstream processing. The Kemi mill has annual capacity of about 465,000 tonnes, so stable slitting affects board quality, material utilization, and delivery times. The actual emissions reduction still needs to be proven through measurement.

### Should a Taiwanese paper-packaging or printing SME buy equipment first?

Not necessarily. First map which stage among slitting, printing, converting, and shipping creates the most waste, downtime, or energy loss. Then decide between an equipment upgrade and process rework, and schedule the work within a maintenance window.

### How can brand customers tell whether a supplier's decarbonization claims are credible?

Ask the supplier to state the improvement area, measurement boundary, time period, product-quality result, and delivery result. In the Südpack case, the direction currently confirmed is process and energy-structure optimization. There is no reduction percentage that can be inferred from the available information.
