The end paper product (paper, paperboard, tissue, cardboard, etc.) dictates the species, or species blend, that is best suited to provide the desirable sheet characteristics, and also dictates the required fibre processing (chemical treatment, heat treatment, mechanical "brushing" or refining, etc.).
If the chips are just ground up with the plates, the pulp is called refiner mechanical pulp (RMP) and if the chips are steamed while being refined the pulp is called thermomechanical pulp (TMP). Steam treatment significantly reduces the total energy needed to make the pulp and decreases the damage (cutting) to fibres.
Mechanical pulping is the process in which wood is separated or defibrated mechanically into pulp for the paper industry.. The mechanical pulping processes use wood in the form of logs or chips that are mechanically processes, by grinding stones (from logs) or in refiners (from chips), to separate the fibers.
Natural fibers or natural fibres (see spelling differences) are fibers that are produced by geological processes, or from the bodies of plants or animals. [1] They can be used as a component of composite materials, where the orientation of fibers impacts the properties. [2] Natural fibers can also be matted into sheets to make paper or felt. [3 ...
Tree-free paper, also known as no tree paper, offers an alternative to traditional wood-pulp paper [1] due to its unique raw material [2] composition. This type of paper is considered more eco-friendly especially when evaluating its entire life cycle. Sources of fiber for tree-free paper [3] [4] [5] Tree-free paper fibers are derived from ...
Natural fibers are composed by microfibrils of cellulose in a matrix of hemicellulose and lignin. This type of structure and the chemical composition of them is responsible for the mechanical properties that can be observed. Because the natural fibers make hydrogen bonds between the long chains, they have the necessary stiffness and strength.

A number of manufacturers are now making disposable foodservice products from a combination of natural starches, recycled fibers, water, air, and natural minerals. [7] These composite products include cups, plates, bowls, cutlery, sandwich wraps, food containers and trays. Ideally these products are easily biodegradable and composted after use.
