Sawdust is a term that, according to the dictionary of the Royal Spanish Academy (RAE), is used as a synonym for sawdust. The etymological root of these concepts is found in late Latin serrāgo.
It is called sawdust or sawdust at particles that are produced when the wood is serrated or sawn: that is, when he cuts it using a saw. A saw, meanwhile, is a tool that presents a metal blade with teeth.
How sawdust is formed
It can be noted that sawdust is a residue that is generated from the sawing of the wood. It is important not to confuse it with other particles that are also produced in sawmills And in the carpentry.
A chip, by example, is a leaf removed by the action of a brush or other type of implement. Its peculiarity is that it usually comes out wound in a spiral. A splinterOn the other hand, it is a long, pointed fragment that falls off when wood or other hard material breaks. In the case of sawdust, it emanates from the wood while sawing is taking place.
Uses of the material
We said lines above that sawdust is considered a residue. However, this material is often used in different ways, thus giving it an economic value.
A frequent use of sawdust is given as ground cover in the field of gardening or in different industries. In the first case, it is used ornamentally, while in other areas it is spread on a surface to increase adherence and make cleaning easier (since it absorbs liquids). Sawdust is also used for hamster soil and others pets Similar.
Sawdust can also be used for the preparation of Organic fertilizers. That is the case of bokashi, where it is combined with peel rice, manure and other substances.
Pressed sawdust is used for the production of pellets that function as fuel. Also for the manufacture of briquettes (solid fuel blocks), used in boilers, stoves and other appliances.
Sawdust on boards
Sawdust is frequently used to make chipboard boards. For its production, sawdust is combined with a adhesive and a pressing is carried out.
The result is a uniform, consistent and stable material, with smooth surfaces regardless of whether its raw material is sawdust particles. Furniture is usually built with these chipboards, although it is important to bear in mind that the humidity it damages them.
The so-called Medium Density Fibreboard, many times called MDF from its acronym in English (medium density fiberboard), they can also carry sawdust. Their manufacture requires the use of wax and resin as a binder, while the panels are created by applying heat and Pressure.
The concept beyond wood
It should be noted that the notion of sawdust can be used to refer to certain non-wood wastes. In this sense, the sawdust from meat, made up of the remains left in the butcher’s machines.
Sawdust is even referred to as ground bone. In fact, meat sawdust sometimes contains meat, bone and other components, such as fat, skin, etc.
