Chips — wood particles with dimensions in the range from several millimeters up to a dozen or so centimeters, made as a result of shredding wood with chippers. Depending on the wood type, the dimensions and quality of wood chips may be the raw material for the production of pellets, briquettes, chipboards, fiberboards, cellulose, for extracting resin and tannin. Chips can be dyed, which is used in decorating greenery areas, gardens, squares, and flower beds. They protect against weeds. They prevent the soil from becoming overly dried, and ensure its proper aeration. They protect the soil against low or high temperatures and their variations. The raw materials for the production of wood chips are mostly waste from the sawmill and forestry industries. Their quality, and calorific value depend on their origin, and on how the raw material is stored.
