AI-Powered Sustainable Wood Panels: Alpine Craft Meets Modern Technology

Traditional Alpine Craft Inspires Innovative Wood Processing

Researchers at Empa and ETH Zurich have developed a groundbreaking method for producing sustainable wood panels, drawing inspiration from the centuries-old Alpine craft of shingle-making. This innovative approach combines traditional techniques with cutting-edge artificial intelligence to create more efficient and environmentally friendly wood-based materials 1

Addressing Climate Change Challenges in Forestry and Construction

The new method comes as a response to the growing impact of climate change on forests and the construction sector. Professor Ingo Burgert, leader of the research team, emphasizes the importance of this development: "The production of panels from split sticks can be done using wood of varying quality and hardwood species, generating less material loss and approaching the strength of solid wood products" 1

Efficient Wood Processing Technique

The researchers have adapted the traditional shingle-making process, which involves splitting wood parallel to its fibers. This method is highly energy-efficient and results in minimal material loss. The team has developed a two-stage splitting process that allows for the use of lower-quality hardwood species and the production of longer sticks 2

Artificial Intelligence for Wood Selection

To overcome the challenge of irregular stick shapes, the team has incorporated artificial intelligence into the process. An automated camera system captures high-resolution images of each wooden bar, which are then analyzed by a neural network. Empa researcher Mark Schubert explains, "With AI, we can determine important wood properties such as stiffness for each stick, regardless of shape, size, or type of wood" 1
