Sawdust has a wide range of applications, covering multiple fields such as agriculture, industry, and daily life. Here are some of the main uses:
1. Agricultural use:
Flower cultivation: Sawdust can be used as a substrate for flower cultivation because it has comprehensive nutrition, loose texture, water retention and breathability, and is clean and hygienic. Suitable for wrapping tall branches of flowers and trees such as azaleas, kumquats, camellias, osmanthus, etc.
Soilless cultivation: After fermentation and disinfection, sawdust can be adjusted for pH and used as a transitional cultivation substrate for test tube seedlings, similar to perlite powder.
Organic fertilizer: Sawdust can be mixed and fermented with pig manure to become high-quality organic fertilizer.
2. Industrial use:
Board manufacturing: Sawdust is an important raw material for manufacturing various artificial boards, such as plywood, particleboard, sawdust board, compressed board, etc. These boards are widely used in decoration and furniture manufacturing.
Fuel: Sawdust can be molded into semi-finished mechanical carbon materials through high-temperature and high-pressure plasticization by a rod making machine, making it an ideal fuel with low investment and fast results. In addition, sawdust can also be directly used for smoking food.
3. Daily use:
Cleaning: Sawdust can be used to absorb oil, such as when mechanics wash their hands.
Animal feeding: Sawdust can be used as a cushion in the pigsty to make it clean and hygienic. Fermented sawdust mixed with pig manure is also a good organic fertilizer.
Horticulture: Sawdust can be used for soil improvement in horticulture, improving soil permeability and water retention.
4. Environmental Protection Application:
Alternative energy: Wood pellet fuel is made from wood by-products or processed wood chips that are dried, pressed, shaped, and cooled. It can replace chemical fuels such as light oil and is an environmentally friendly commercial fuel product. It has been widely popularized in developed countries such as North America and Europe.
Overall, the full utilization of sawdust not only improves the utilization rate of wood and reduces waste, but also plays an important role in environmental protection and sustainable development.
