2. Production of Wood Chips

The production of wood chips begins with the harvesting of timber or other woody materials from forests. The process typically involves the following steps:

a. Harvesting

Trees are harvested from forests using various methods, including clear-cutting, selective cutting, and thinning. The choice of method depends on the forest management objectives and the desired outcome.

b. Chipping

Once the trees are harvested, they are transported to a chipping facility where they are processed into wood chips. This is typically done using a wood chipper, which is a machine that cuts the wood into small, uniform pieces.

c. Sorting and Grading

After chipping, the wood chips are sorted and graded based on size, quality, and intended use. Some chips may be further processed to remove bark or other impurities.

d. Storage and Transportation

The final step in the production process is the storage and transportation of the wood chips to their final destination. Wood chips are often stored in large piles or silos and transported by truck, train, or ship.
