An overview of the importance of forest products, the history of forest products technology, and the role of forest products in various industries.
Introduction to Forest Products Technology
Key concepts, processes, and applications
| Category | Typical Materials | Common Uses |
|---|---|---|
| Solid Wood Products | Lumber, plywood, LVL, CLT | Construction, furniture, flooring |
| Engineered Wood | Particleboard, MDF, OSB, laminated veneer lumber | Cabinets, panels, packaging |
| Pulp & Paper | Kraft pulp, newsprint, tissue, specialty papers | Printing, packaging, hygiene |
| Non‑Wood Forest Products (NWFP) | Resins, gums, essential oils, berries | Pharmaceuticals, cosmetics, food |
| Bio‑energy & Bio‑materials | Wood chips, pellets, bio‑char, bioplastics | Heating, power generation, biodegradable plastics |
