Wood Wool Cement Board Plant

For the Eltomation production line alone, the estimated installed capacity is approx. 900 kVA. When adding finishing operations, total installed power requirements are estimated at 1800 kVA.

While cement production contributes to CO₂ emissions, the industry is actively working on solutions to reduce its impact. In WWCB production, more than half of the board’s mass consists of renewable wood and water, making it a more sustainable option than many traditional building materials. Additionally, the low density of WWCB means that less material is needed to cover a given volume, further improving its environmental footprint. In general, we can state that 1 m³ of wood used creates approx. 4 m³ of end product.

Our plants are designed to (optionally) use LC3 cement as a lower-carbon alternative to standard Portland cement without compromising board quality. In addition, many of our clients add a percentage of limestone to reduce the overall cement content, further lowering emissions while maintaining durability and performance.

For all products coming from the production lines the ingredients are the same: softwood (typically pine or spruce), cement and water. Additives like limestone can be added to the mix to reduce the cement content and tweak the product for certain use cases. Rough proportions of the raw materials are as follows:

Wood wool: 31%

Cement: 45%

Water: 22%

Waterglass: 2%

Our large element line runs a zero-waste production process, with all trimming waste reintegrated into new products. For our standard lines, we are actively working on recycling all trimming waste back into production. However, we do not process construction waste from demolition sites.

No. Only the very first section of the production line (block handling, production of wood wool and mixing with water and cement) is the same. After the dosing and mixing process, the production lines for acoustic panels and large elements follow the same principle but are created on different machines.

We have extensive knowledge we can share when it comes to raw materials needed, log yard capacity, dust extaction capacity, etc. we share in detail in the pre-engineering stage once we seriously proceed with a project.

The company’s origins are in the 1950s. Since then, over 130 projects have been realized.

Switching between product thicknesses (using the same wood wool type) takes only a few minutes. A new form is supplied to the line, and settings adjust automatically in the Control System. Changing wood wool types (e.g., from 1.0 mm to 2.0 mm) requires swapping the 16 pre-assembled knife cassettes in the Eltomatic, which takes about 15 minutes – typically done during a break.

Operational requirements vary per client. WWCB plants are designed for full 2- or 3-shift production, with each shift running for 7 hours plus 1 hour for cleaning. Most lines operate 5-6 days per week.

Yes. Several Eltomation personnel will remain on site for 6 weeks after first commissioning to make sure the plant runs smoothly, and local operators / supervisors are properly trained.
