The 170-million-euro investment will be built directly subsequently to the sawmill. All elements for the load-bearing timber construction, the roof structure, walls and ceiling elements made of wood are manufactured from PEFC-certified wood in Mayr-Melnhof Holz' own timber processing plants.

Only ten months after the groundbreaking ceremony, the shell of the building is now complete. The occasion to celebrate the traditional topping-out ceremony. Representatives and employees of all the companies involved in the construction were there:
 

• Warnecke Engineering GmbH
• Arinco planungs + consulting gmbH
• TGA Engineering GmbH
• pde Integrale Planung GmbH
• SYNALP GmbH
• Ingenieurbüro Rudlof GmbH
• sblumer ZT GmbH
• HT & Generalunternehmer & Industriebau GmbH
• Strobl Holzbau GmbH
• Bacon Gebäudetechnik GMBH
• Elin GmbH
• Bmstr. DI (FH) Andreas Walter Mitteregger
   

Board member Richard Stralz and owner Franz Mayr-Melnhof-Saurau thanked the project team and employees of Mayr-Melnhof Holz, the planners, architects, all companies involved in the construction and their employees for their efforts. The youngest apprentice of the timber construction company Strobl solemnly gave the topping-out speech (“Gleichenspruch”) and threw a glass onto the floor. This tradition is supposed to bring good luck for the further course of construction. Very impressively burned onto a large cross-laminated timber board from the Gaishorn site, the “Gleichenspruch” will find a lasting place in the cross-laminated timber plant after its completion.

Construction is in full swing and commissioning is planned for December 2022.

The Mayr-Melnhof Holz Holding AG group, located in Leoben, Austria, signed a contract in December last year to acquire the Swedish sawmilling group Bergkvist Siljan AB (publ.) from the investment fund ESSVP IV., advised by Orlando Nordics AB. Having gained the approval of the competition authorities, the acquisition is completed as of 01 February 2022.

The new sites in Insjön, Mora, and Blyberg (all in central Sweden) complement the existing sawmills in Leoben (Austria), Paskov (Czech Republic), and Efimovskij (Russia) perfectly and move Mayr-Melnhof Holz, with around 5 million cubic metres of log processing capacity, up to number 3 of Europe’s largest sawmillers. For the first time in its 170-year long history, the group expects turnover to exceed one billion Euros in the 2022 financial year.

„We are very much looking forward to working with our new Swedish colleagues. Together we will realise and build on the synergy and growth potential in sales and operations, and strengthen our position in the market“, said Richard Stralz, CEO of Mayr-Melnhof Holz Holding AG. The Bergkvist Siljan brand and the existing management team will remain in place.

About Bergkvist Siljan

Bergkvist Siljan produces around 850,000 cbm of spruce and pine sawn timber annually. The group consists of three modern sawmills as well as one of the largest container terminals in Sweden, with a capacity of up to 50,000 TEU per year, and a direct rail link to Göteborg port. Michael Wolfran, CFO of Mayr-Melnhof Holz Holding AG, adds: „Bergkvist Siljan, with a turnover of almost 300 million Euros, employs 285 people. Both Mayr-Melnhof Holz and Bergkvist Siljan have a long tradition of family ownership over more than a hundred years, and together our sales make a perfect fit. Along with the Scandinavian market, the sawmill group serves the markets of the Far East, Western Europe, and North Africa. “

Mayr-Melnhof Holz, one of the leading companies in the European sawmilling and engineered wood products industry, will grow with this acquisition its lumber production capacity by approximately 50 % to more than 2.7 million cubic meters of sawn timber per year.

The new sites Insjön, Mora and Blyberg, right in the middle of Sweden, complement the existing sawmills in Leoben (Austria), Paskov (Czech Republic) and Efimovskij (Russia) perfectly and create a starting point for the market entry of the Mayr-Melnhof Holz Group into Scandinavia.

“The Mayr-Melnhof Holz Group and Bergkvist Siljan make a perfect fit. Both have comparable roots, both are family businesses with a long tradition exceeding 100 years and both are committed to sustainability. We are looking forward to a rewarding cooperation and the mutual exchange of experiences”, Richard Stralz, CEO of the Mayr-Melnhof Holz Holding AG, is pleased to comment about the just completed acquisition. CFO Michael Wolfram adds: “We are very optimistic that we can realize the synergy and growth potentials in sales and operations very quickly, not only securing our market position but expanding it at the same time.”

“Mayr-Melnhof Holz, with its family roots and impressive track record, is a great long-term majority owner for Bergkvist Siljan. We have come a long way since the merger between Siljan Group and Bergkvist-Insjön in 2019, becoming part of a successful international wood industry group is the natural next step for us. We thank ESSVP IV and Orlando Nordics for their support and cooperation since 2018 and look forward to working together with the team from Mayr-Melnhof Holz", says Ulf Bergkvist, Chairman of Bergkvist Siljan.

Using wood reduces greenhouse gas emissions.

One cubic meter of wood stores 250 kilograms of carbon from one ton of CO₂. And we all know that CO₂ is a major contributor to the greenhouse effect.

This means that wood products serve to temporarily store carbon, and they continue to do so throughout their lifetime. When it comes to drastically reducing greenhouse gas emissions for a more climate-friendly future, there is no getting around the valuable raw material that is wood. We encounter products made of wood everywhere in our everyday lives: whether in toys, as windows, as parquet flooring or furniture, or even as wooden homes.

Wood products therefore act like a second forest, the carbon remaining bound in them. And of course, the wood removed from the forest is replanted through reforestation or natural regeneration. These young trees extract CO₂ from their environment again by means of photosynthesis, store carbon and release vital oxygen into the air. Like in a perfect perpetual motion machine, the use of wood and reforestation permanently removes CO₂ from the atmosphere and stores carbon.

Wood has up to half the ecological footprint compared to other building materials.

Around 40 percent of the total resource consumption on earth – materials and energy – is currently accounted for by the construction sector. Increases in efficiency and thus reductions in energy demand and heating requirements for building use will not be enough to reduce consumption.

A major contribution to achieving the climate targets is made by the choice of building material. Wood is simply unbeatable in this respect. Today, wood building products and innovative wood structures can in many cases replace conventional, carbon intensive building materials such as brick, concrete and steel. These are much more carbon intensive because they require much more fossil energy, such as oil or coal, in their production and transport to the construction site. Thus, wood has two effects: On the one hand carbon remains bound in wooden products and on the other, using wood prevents the use of carbon intensive materials and thus the emission of additional harmful greenhouse gases.

Wood can be recycled which is an exceptionally important factor when looking at its entire life cycle. At the end of its lifetime, a wooden building is simply disassembled and its valuable wood turned into many environmentally friendly, carbon-neutral products such as furniture boards, pellets or briquettes.

The more carbon-releasing materials are replaced by wood products the more carbon emissions into the atmosphere can be avoided. Arno Frühwald from the University of Hamburg has crunched the numbers: "… every cubic metre of wood that replaces other building materials reduces the CO₂ emissions in the atmosphere by an average of 1.1 tons of CO₂ ...” (Source: Holzprodukte sind Kohlenstoffspeicher, proHolz, only available in German)

Wood even improves resource efficiency by several factors: It grows back and is available in the region. 60 % of the surface of Styria, for instance, are covered by forests. Its forests grow more wood than is harvested. Thus, we have more than enough of this valuable resource.

The future-oriented intralogistics solution consists of a fully automatic, 3-aisle high-bay warehouse, an innovative conveyor system, a fully automatic strapping and squared timber stacking system, a stretching system, stacking and labelling machines, and a modern truck loading system. In addition, intelligent warehouse management, plant control and plant visualisation are integrated and communicate with the internal ERP systems.

The sawn timber packages are received from the grading and planing plant, weight and contour are controlled and transported to the high-bay warehouse. There, they are automatically placed in temporary storage. To avoid empty runs, a sequence- and route-specific retrieval order is executed immediately.  

The retrieved packages are automatically supported with squared lumber, strapped, and, if required by the customer, also wrapped and automatically labelled. At a robot station for truck loading, adjacent to the loading hall, up to four packages are stacked to a single stack; for packages without squared lumber, intermediate lumber can be inserted here for stacking by robot. The stacks are taken to one of five staging lanes by a distribution truck. There, a complete truck load is provided and loaded by means of a loading crane. 

In the downstream zone of the high-bay warehouse, retrieval tables are provided in each rack aisle for internal transport. Here, the sawn timber packages required in the cross-laminated timber plant are retrieved and automatically fed to production via a distribution car.

The high-bay warehouse has 7,623 storage locations, and the storage and retrieval capacity is 62/71 packages per hour. With the construction of the fully automated high-bay warehouse, Mayr-Melnhof Holz is taking a further step towards modernisation and positioning itself for the future. The company has commissioned HÖRMANN Logistik with the realisation of the project. The construction is running at full steam, the commissioning is planned for December 2022.

What's Mayr-Melnhof Holz’ pellet production capacity?

Mayr-Melnhof Holz produces certified and quality-controlled pellets at all of its three sawmill sites in Leoben (AT), Paskov (CZ) and Efimovskij (RU). Our intended production volume for 2021 is roughly 300,000 tons of pellets, exclusively at ENplus® A1 for use in private and commercial applications. 

What do pellets contribute to the fight against climate change?

When wood is processed, up to 40 percent of the input is in the form of sawdust or shavings and wood chips, just the right raw material for the production of pellets. Thus, none of this valuable raw material that is wood is wasted, but added value is created, making a significant contribution to supporting the European transition from fossil fuels, which are responsible for high CO₂ emissions, to exclusively renewable energy sources. Needless to say that Mayr-Melnhof Holz only processes wood from sustainably managed forests that are PEFC certified or meet similar standards recognised by the PEFC. This way, we promote socially and environmentally compatible forest management and guarantee natural, ecological wood products.

Why did Mayr-Melnhof Holz opt for ENplus® certification?

We have been a member of the Austrian Pellet Association from the get-go (proPellets Austria). Together with our colleagues from the Association we have campaigned for the introduction of a uniform certification standard to clearly define pellets quality. This gives our customers the peace of mind to only use pellets of exceptional quality.

What effects does the certification system have on the pellets market?

The ENplus® certification system defines clear guidelines for producing companies, retailers and delivery services. All market participants meet the same requirements meaning that the end users can rest assured to receive a product of high quality. The uniform standard is also a clear advantage for the producers of boilers and pellets ovens. They can now adapt their heating systems to a clearly defined quality.

What are the biggest challenges a pellets producer faces that wants to supply end users with a premium ecologically friendly product?

The basic prerequisite for the production of high-quality pellets is the use of the right raw material. Since we use our own sawmill by-products - fresh sawdust or wood shavings – we know exactly the origin and quality of the raw material for pellet production. Highly automated production facilities with extensive quality controls, as well as specially designed storage silos are another essential point to ensure a high quality pellet. The reliable availability of pellets through our own raw material supply gives our trading partners the possibility to supply their customers well at any time.

Will people in Europe discover the benefits of quality pellets and change the way they heat? 

Many consumers already trust high-quality pellets, but some only after bad experiences with non-certified pellets. We still have some work to do in making people aware. However, it is undisputed that we must protect our environment for ourselves and the next generations and put a stop to climate change. Pellet heating systems, operated with certified pellets, make a significant contribution to this. 

Why are some still hesitant about switching to pellet heating? What would you say to these people?

Converting a heating system is sometimes quite expensive. In countries where the government provides subsidies for the switch, the energy transition advances more quickly. We hope that many more countries will discover the benefits of biomass use for our climate and environment and help people replace fossil fuel heating systems with heating systems powered by renewable energy.

Also, the argument that burning pellets pollutes the air is still widespread. This argument is definitely not justified, because modern pellet heating systems operate almost emission-free. We would like to recommend to critics to visit the website of their national pellets association or www.enplus-pellets.eu. There they will find reliable information on wood pellets for end users.

RAW MATERIAL WOOD

Mayr-Melnhof Holz pursues a no-waste policy. In Reuthe, this means that residual wood and sawmill by-products from glued laminated timber and formwork panel and beam production that cannot be further utilised are now used for carbon-neutral heat generation. 

Two new biomass boilers replace the previously separated heat generation plants. Until recently, a cogeneration plant had been used in the “Western Zone” and two wood boilers in the “Eastern Zone”. The new biomass heating plant saves more than 12,200 tons of CO₂ emissions per year.

Now, the two operating zones are connected by a pipeline in an underground collector corridor. In addition, a balancing tank was installed in the hot water circuit to balance the load between the biomass boilers and the consumers. The annual heat requirement for drying the sawn timber, operating the production facilities and heating the buildings is now covered entirely by the company's own energy. 

Mayr Melnhof Holz Reuthe invested some 3.5 million Euros into this environmentally and climate-friendly project, supported by “Domestic Environmental Support” fund provided by the Federal Ministry for Climate Protection, Environment, Energy, Mobility, Innovation and Technology.

Ground was broken on 28 May. Despite strict Covid-19 event restrictions, but in glorious sunshine, many guests from politics, interest and industry groups, funding bodies, project partners from the construction industry, the planners and architects as well as the “HoLzBsp” project team followed up on the invitation sent out by owner Franz Mayr-Melnhof-Saurau, Supervisory Board member DI Rainer Zellner (Chairman), Dr. Nikolaus Ankershofen, Univ.-Prof. Mag. Dr. Romuald Bertl, Mag. Rupert Zieseritsch and Ing. Franz Rappold as well as the Board of Directors, DI Richard Stralz (CEO) and DI Michael Wolfram (CFO).

Franz Mayr-Melnhof-Saurau welcomed the following honorary guests:

• DI Michael Esterl, General Secretary for Digitisation and Economic Location at the Federal Ministry
• State Secretary Ök.-Rat Johann Seitinger filled in for Hermann Schützenhöfer, the Governor of Styria
• Member of the Styrian State Government Helga Ahrer filled in for Anton Lang, the Deputy Governor

Committing to Styria as an economic location
This investment marks a clear commitment to Styria as an economic location. "The supply of raw materials from the Styrian forests, the existing infrastructure, a well-trained workforce, and the supply of sawn timber from the directly adjacent sawmill make Leoben the optimal location for this investment in the future, which, processing the carbon-neutral material wood, also makes an important contribution to sustainability and active climate protection," says Richard Stralz, CEO of Mayr-Melnhof Holz Holding AG, who is pleased with this investment boost, which will not only improve the competitiveness of the Mayr Melnhof Holz Group, but also secure existing jobs and create some 50 new jobs in the region.

Facts about the Mayr-Melnhof Holz cross-laminated timber plant in Leoben

About cross-laminated timber
cross-laminated timber, also known as glulam, is a solid wood building element made from several layers of sawn timber permanently cross-laminated to form panels. This crosswise structure guarantees dimensionally stable and stiff building components with excellent structural and physical properties. As a building material, wood is currently experiencing a renaissance. Made from the regionally available raw material wood, cross-laminated timber is a carbon-neutral, sustainable building material. It is easy to shape and, thanks to a high degree of prefabrication in the factory, has various applications such as walls, ceilings and roof constructions. It can be used to erect buildings up to six storeys tall and higher entirely from wood – family homes, leisure facilities, kindergartens, nursing homes, restaurants and much more – or to easily extend buildings upwards. MM crosslam is the brand name of cross-laminated timber products from Mayr-Melnhof Holz.

Cross-laminated timber protects the climate
Today, wood can – in many cases – replace conventional building materials such as concrete and steel that emit high amounts of CO₂, thus having two positive effects on the climate: Firstly, by storing carbon dioxide and secondly, by preventing additional carbon emissions during the production process of conventional building materials which are then replaced by wood. As a natural and regrowing building material, cross-laminated timber makes a significant contribution to active climate protection. Cross-laminated timber produced by Mayr-Melnhof Holz is PEFC-certified.

Since the start-up of the sawmill in Paskov in 2004, the production volume had increased to around 800,000 cubic meters of sawn timber and 90,000 tons of pellets per year. Since 2020, the site has also had a wet storage facility with 1.4 hectares for up to 70,000 solid cubic meters. The existing heat generation plants had been running at full speed for 17 years, and the wet storage facility means new demands on a biomass power plant in terms of the usability of wet bark and wood shavings while complying with strict exhaust gas limits. This and the continuous increase in production prompted Mayr-Melnhof Holz to invest a sum of 6.5 million Euros in a new state-of-the-art biomass boiler supplied by Carinthian power plant specialist Urbas as well as in the overhaul of the existing plants. 

High quality standards for technology and environmental protection were the guiding principles for the decision. During realisation the team incorporated the lessons learned at the Russian sawmill site Efimovskij: Its third biomass boiler had been installed in 2019.

Thanks to this expansion, the Paskov plant is now able to dry its entire production volume and fully utilise sawmill by-products at the site. 

Mayr-Melnhof Holz pursues a no-waste policy. This sustainability approach spans across the entire procurement and production process. 100 percent of the valuable resource that is wood are utilised. In Paskov, only bark as well as residual wood and sawmill by-products that cannot be utilised are used as fuel. 

At the Russian Efimovskij site, some 700,000 cubic metres of round timber sourced from sustainably managed forests are processed annually while the output is approx. 380,000 cubic metres of sawn timber and 60,000 tons of pellets. All of the sawn timber is dried on site. 

The two existing biomass heating plants were no longer able to meet the increased demand in heat. That's why Mayr-Melnhof Holz decided to build a third heating plant, tasking power plant specialist Urbas from Carinthia with the project. The project took off in the spring of 2019 during ongoing operations and the new boiler has been in operation since autumn. The two existing heating plants were overhauled and technically brought up to date.

Mayr-Melnhof Holz pursues a no-waste policy. This sustainability approach spans across the entire procurement and production process. 100 percent of the valuable resource that is wood are utilised. In Efimovskij, only the bark taken off the processed logs as well as (during particularly harsh winters) firewood from its own forests, are used as fuel. 

Directly next to the existing sawmill in Leoben, not only a new state-of-the-art cross laminated timber plant is being built in a multi-stage process lasting three years, but also a high-performance re-grading and planing plant as well as a fully automated high-bay warehouse. In a further step, the company intends to comprehensively modernise the sawmill.

"The supply of raw materials from the Styrian forests, the existing infrastructure, a well-trained workforce, and the supply of sawn timber from the directly adjacent sawmill make Leoben the optimal location for this investment in the future, which, processing the carbon-neutral material wood, also makes an important contribution to sustainability and active climate protection", says Richard Stralz, CEO of Mayr-Melnhof Holz Holding AG, who is pleased with this investment boost, which will not only improve the competitiveness of the Mayr Melnhof Holz Group, but also secure existing jobs and create new ones.

Mayr-Melnhof Holz was awarded by PEFC Austria on 20 November 2019. What led up to the award: The company meticulously checks the origins of its raw materials, guaranteeing seamless traceability all the way back to the forest. Mayr-Melnhof Holz further processes this valuable resource – that is certified in accordance with PEFC or other, similarly stringent standards recognised by the PEFC– to wood products whose production process is also precisely checked and monitored and that area also certified in accordance with the comprehensive PEFC standards. This includes sawn timber, pellets, glued laminated timber, duo & trio beams, cross laminated timber, wooden concrete formwork panels and beams as well as cross laminated timber for timber concrete composite elements. 

The PEFC (Programme for the Endorsement of Forest Certification Schemes) is the world's leading institution for the promotion, preservation and distribution of actively sustainable and climate-friendly forest management. The PEFC label on wood and wood products guarantees that they have been sourced from ecologically, economically and socially sustainable forest management. To boost consciousness for sustainable forest management, the PEFC Award was created in Austria in 2011. The Award goes to companies that make significant contributions to careful and responsible forest management / wood processing in Austria.

Richard Stralz, the CEO of Mayr-Melnhof Holz Holding AG, highlights the importance of sustainable forest management in the light of advancing climate change: “We need to take appropriate steps towards a liveable future with a healthy climate in due time. And that means NOW. Large-scale scientific and economical efforts are required in the short term to quickly identify and implement the appropriate measures towards sustainable and future-oriented forest management. PEFC certificates are going in the right direction. PEFC stands for sustainability and safety in controlled forest management – globally.”
