What Are Wood Chips?

Wood chips are small to medium-sized pieces of wood that are produced by chipping larger pieces of timber. They are typically a byproduct of sawmills, where logs are processed into lumber. The chips can vary in size and shape depending on the machinery used and the intended application.

Production Process of Wood Chips

The production of wood chips begins at the sawmill, where logs are debarked and cut into lumber. The leftover pieces, such as slabs, edgings, and trimmings, are then fed into a wood chipper. The chipper cuts these pieces into smaller, uniform chips. The chips are then screened to remove any oversized or undersized pieces, ensuring consistency in size.

Types of Wood Chips

Wood chips can be categorized based on their size, type of wood, and intended use. Common types include:

  • Softwood Chips: Derived from coniferous trees like pine and spruce, these chips are often used in pulp and paper production.
  • Hardwood Chips: Sourced from deciduous trees like oak and maple, these chips are preferred for landscaping and mulching.
  • Mixed Wood Chips: A combination of softwood and hardwood chips, suitable for various applications.
