Today, due to environmental and aesthetic factors, a variety of solid wood furniture is an indispensable part of people's lives. The processing of a solid wood furniture includes cutting, drying, planing, engraving, woodworking, sanding and painting and waxing. In each of these steps, the remaining material is inevitably produced. So how do these residual materials come from, how much material is there, and how should they be handled?
First of all, there are roughly five main types of surplus materials. They are:
1, bark surplus material
2, wood natural defects
3, the material is left over
4, carved materials
5, sawdust wood powder
Then, what are the remaining materials that can be used to their value?
1, burn directly
Most companies have their own drying workshops, which can provide some energy supply by burning the surplus material. This method is popular among most companies because it is simple and rude and directly effective. But it is undeniable that the potential value of wood itself is much greater than the value it provides for combustion. Treatment in this way is a great waste.
2, sell cheaply
This method seems to be simpler. It can solve the waste accumulation caused by the workshop production at a time, and can improve the working environment of the workers. At the same time, the surplus materials sold can be directly converted into the income of the funds. However, the price of surplus materials resold in this way is very low. The price of 1 ton of surplus material is around 800-1000 yuan, which is far from the price of purchased materials. Such as Siamese rosewood, the price at the time of purchase is more than 400,000 tons.
3. Design reengineering
Some mahogany furniture companies will make the corners into ornaments or handicrafts such as bracelets. This design re-creation makes the surplus material create value far greater than the material itself. However, considering the manual and equipment, it is still difficult to achieve on a large scale. Other treatments include making production tools, filling furniture, and so on.

4, making wood-based panels
It seems that it is rare to see enterprises that use wood furniture as raw materials for wood-based panels in the Chinese market, but there are already quite mature technologies in foreign countries. For example, Maier is a professional equipment supplier for wood-based wood chips and shavings preparation systems in the world. In the early 1990s, they developed a standard multi-machine configuration system for recycling waste wood. There are also many related manufacturers in China. The drum chipper produced by them can crush the waste of furniture and obtain good-looking veneer chips. The three-rotor hammer planer can break the veneer chips into craft shavings, and at the same time they are different. The shape of the screen can control the shape and size of the shavings and the proportion of the surface layer shavings.
However, because solid wood furniture factories generally do not have a production line for making wood-based panels, if they want to make wood-based panels, they must purchase equipment. One side is the profit that can be obtained when it is sold, while the other side needs to be invested and the return is nowhere in sight. Most companies have chosen the former.
5. Other uses such as organic fertilizer
The large amount of organic solid waste contained in the remaining material can be directly used as an organic fertilizer to assist the production of fertilizer, and can also be converted into charcoal by pyrolysis. At the same time, the wood residual material can also be used as biomass fuel. The state has already had relevant environmental protection requirements for coal-fired boilers, and many places have already begun to implement. Biomass pellet fuel is a clean renewable energy source that does not contain sulfur and phosphorus. It does not produce sulfur dioxide and phosphorus pentoxide when burned, so it does not pollute the environment. It is an ideal alternative fuel for traditional energy sources.
After reading so many treatments above, I believe that people have a certain degree of understanding of the value of wood surplus materials. And the advantages and disadvantages of these methods are obvious. If the precious solid wood materials can be re-developed and reused, and popularized, it is believed that the use of social resources is beneficial to environmental protection and further development of the industry. It is an indispensable responsibility for every furniture company to properly use the surplus materials and let every piece of wood play its due value.
