A solid wood furniture production mainly includes the following processes: blanking – drying – pressure planing – engraving – carpentry – grinding – paint waxing.
In every step of the process, wood scrap is inevitably generated. Where does this wood scrap come from and where does it go? With this problem, the author visited a number of furniture companies and found that these wood scraps are mainly: bark, open materials, residual materials, natural defects, carved excess material, sawdust, wood flour and so on. How does the factory deal with these scraps? Burn it! Sell it! This is the more common answer I got.
Most companies have their own drying workshops, which can provide part of the energy supply by burning wood scrap. This method is popular with most companies because of its simplicity, rudeness, and direct effectiveness.
However, it is undeniable that the potential value of wood itself is much greater than the value it provides by burning. Handling it in this way is a great degree of waste.
This method seems simpler. It can not only solve the waste accumulation caused by workshop production, but also improve the working environment of workers. At the same time, the surplus materials sold can be directly converted into the income of the funds.
However, in fact, the price of surplus material resold in this way is very low, which is far from the price of purchased materials.
Some mahogany furniture companies will make wood scraps and other ornaments or handicrafts. This way of design remoulding makes the surplus material create much more value than the material itself.
However, taking into account the cost of labor and equipment, this method is still difficult to achieve on a large scale. Other methods of processing include making production tools, filling furniture, and the like.
Furniture companies have a strong desire for the use of wood residues, but they suffer from no good solutions. After visiting a panel furniture company, the author suddenly thought, why not use this spare material to make wood-based panels or presswood pallets?
Making artificial panels or presswood pallets
In the market, it is rare to see companies that use furniture as raw materials for making panels and presswood pallets. Does it mean that furniture can’t be used to do it? The author reviewed many domestic and foreign researches on the processing performance, physical properties and mechanical properties of particle board produced from discarded wood materials. The results show that it is entirely feasible to use wood waste to make man-made boards and presswood pallets! And at home and abroad in this area has a very mature process!
Companies that use surplus materials to manufacture man-made plates and core presswood pallets can also enjoy preferential tax policies in the country while saving costs.
But why can’t you see companies doing so? Because solid wood furniture factories generally do not produce production lines for wood-based panels and presswood pallets, a large amount of investment is required in the early stage. One side is simple and crude processing, the other side is the need for investment and the return is indefinite, most companies have chosen the former.
In the long run, making artificial sheets and presswood pallets is undoubtedly a good choice. At the same time, the furniture companies should establish a complete residual material recycling system based on their specific conditions, and provide specific solutions for different residual materials. This will not only bring direct economic benefits to the company, but more importantly, it will increase the green awareness of companies and consumers. This is far-reaching for the furniture industry and the entire industry.
Other processing methods
In fact, in addition to the above methods, there are still quite a lot of treatment methods for furniture wood scrap. The large amount of organic solid waste contained in the residual material can not only be used as auxiliary fertilizer but also can be directly made into organic fertilizer, and can also be used in the way of pyrolysis. It is used as charcoal.
At the same time, wood residues can also be used as biomass fuels. The state has already had relevant environmental protection requirements for coal-fired boilers, and many sites have begun to implement them. 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 it is burned. It does not pollute the environment and is an ideal alternative fuel for traditional energy sources.
It is an issue that every furniture company should consider and the unshirkable responsibility to properly use the surplus materials of furniture to make each piece of wood play its due value.
