From logs to engineered wood: A more efficient and environmentally friendly way to "regenerate" timber resources.
Nov 05,2025
Wood is one of the earliest natural materials used by humankind. But did you know that a tree undergoes a scientific journey of "structural remodeling" from being felled to becoming the furniture, flooring, and cabinet materials we use every day?
Multiple forms of a tree
In wood processing, logs are sawn, planed, and sliced, transforming them into different forms of wood units: lumber, chips, flakes, fiber, and flour. These different sizes and forms of "wood elements" determine the types of engineered wood products that can be manufactured.
As shown in the diagram, from logs to microscopic wood fibers, wood can be broken down into more than ten structural units, ranging from visible wood segments to nanoscale cellulose crystals, each representing a new possibility.
Wood “Reprocessing”: The Birth of Engineered Wood Panels
When these wood units are reassembled, pressed, and glued, engineered wood products are created. Typical engineered wood products include:
Plywood – Made by hot-pressing multiple layers of veneer in a cross-grain pattern, it boasts high strength and stability;
Particleboard – Made by gluing and pressing together wood chips and shavings, it saves timber and is affordable;
Medium-density fiberboard (MDF) – Made by hot-pressing wood fibers, it has a uniform texture and is easy to finish;
Oriented strand board (OSB) – Made by oriented strands of wood, it has high structural strength and is commonly used as a building and flooring substrate.
The advent of engineered wood products has increased timber utilization from less than 50% in the traditional sawn timber era to over 90%, greatly alleviating the pressure of logging on natural forests.
Science makes wood more environmentally friendly
Modern engineered wood products are not merely substitutes for wood, but also representatives of green materials technology. By precisely controlling veneer thickness, hot-pressing temperature, and adhesive ratios, the produced boards meet international standards in terms of physical strength, moisture resistance, and environmental friendliness. Meanwhile, the application of emerging technologies such as low-formaldehyde adhesives, nanofiber reinforcement technology, and biodegradable composite layers is making engineered wood products safer and more sustainable.
Today, the flooring, cabinets, tables, chairs, and wall panels in our homes may very well all come from different forms of the same tree—logs become veneers, and veneers become composite boards. Wood continues to extend its value in our lives in new ways. The engineered wood industry is a bridge connecting forests and modern life. It transforms wood from a "disposable material" into a "recyclable ecological resource."
