The production process of cross-laminated timber elements, one of Stora Enso’s main massive wood construction products, is defined and constrained by several parameters. Stora Enso also wants to minimize the waste generated in the process. We are now looking for an optimization tool for the stakeholders working with CLT production planning and implementation.

Opportunity overview

CLT is an environmentally friendly construction material made of at least three crosswise glued single-layer boards using raw timber materials with different widths, surface qualities, and thicknesses. The master panel consisting of single layers is then cut into elements. However, in the cutting process, some of the master panels are wasted. This is currently minimized by a manual planning process called nesting, which has to be done twice for offers and production planning. The current process begins with a customer using computer-aided design software for the building design, which then is broken down into panel designs and manufacturing data using computer-aided manufacturing software. Finally, the load and delivery are optimized to minimize logistics costs and environmental impact. The software optimizing this process should be able to consider the various panel types and combinations in three dimensions: machinery control restrictions and load planning. Experts will still use the solution, but it should allow access to several stakeholders. As the complexity of CLT production will most likely only increase in the future, the answer should also be flexible enough to include new objectives and constraints.

Your opportunity with Stora Enso

Stora Enso is ultimately searching for a long-term service provider that strives to improve our solution further and maintain continuous quality service. We are also open to an option and have previous experience with joint development agreements to accelerate the growth of your solution if needed. We are looking to collaborate and share our industry knowledge to provide you with valuable information about our manufacturing process, enabling your company to further opportunities within the industry.

Examples we're looking for

3D CLT nesting optimisation

Stora Enso currently uses a 2D solution for panel nesting, and now we want to find a comprehensive tool for optimizing the waste, price, and production planning with the efficiency of the CNC process. Manufacturing industry experience could most likely help solve issues but is not required.

Intelligent solutions for production and pricing

We understand there might be even more intelligent solutions for CLT production automation than we currently think. While nesting remains the critical objective, your answer could have add-on functionalities, for example, in the pricing fields, or that could further optimize the supply chain.

Part of the global bioeconomy, Stora Enso is a leading provider of renewable products in packaging, biomaterials, and wooden construction and one of the largest private forest owners in the world. We believe that everything that is made from fossil-based materials today can be made from a tree tomorrow.
