Wood waste recycling

Wood waste is everything saved after logging, including tree roots, branches, pieces of wood, bark, shavings and wood chips. It is not garbage but valuable material which remains in excess during wood processing or sanitary tree felling.

Wood wastes are safe for human and nature except the possibility of ignition if stored for a long time in an inappropriate place. For many companies who do logging wood waste is a problem, because up to half of material can be discarded. Burning such a mass is not only not profitable, but also unsafe.

The only correct decision might become wood waste recycling. Various products can be obtained from wood waste: building materials (shields, plates, panels), fuel briquettes, pellets and even plant fertilizer.

One of promising directions is to get charcoal from wood waste. Charcoal is produced using pyrolysis- thermal decomposition without oxygen access. Color of qualitative charcoal is black with blue tide. Composition depends on carbonization temperature. The higher the temperature the more carbon and less hydrogen, nitrogen and oxygen. With time its ability to absorb vapor and gas reduces and it loses the ability to self-ignite.

This ecologically safe fuel has a number of advantages:

• does not emit harmful materials to atmosphere;
• has high heat transfer;
• does not ignite by itself;
• burn with no flame and smoke;
• it can be compressed into briquettes which take less space;

Not only wood is suitable for the production of charcoal, but also woodworking waste. With the help of special equipment, coal briquettes can be obtained from sawdust, bark, wood chips, branches, humps, stumps and pieces of wood. Let’s consider the main stages of production.

1. Wood waste is crushed to small fractions.
2. Put in the drive.
3. They are sent to the pyrolysis furnace.
4. The finished mass is placed in an industrial mixer.
5. Using a roller press, coal briquettes of the desired size are obtained.
6. Charcoal is dried in a drying machine.
7. The finished products are packed and wrapped.

Wood waste is perfectly recyclable, allowing you to save natural resources. Despite transportation and other costs, the disposal of wood waste is economically feasible. Animal litter and wood flour are produced from woodworking waste, and are often used in the construction industry, but biofuel production remains the most popular application.

Charcoal is one of the types of such fuel. There is always a demand for it. After all, it is used not only in everyday life for heating rooms, cooking and lighting fireplaces, but also in the industrial sphere. For example, in filters for water purification, in the smelting of metals and the production of cast iron. Charcoal can be produced from different types of wood, but obtaining from wood waste allows for more efficient use of available resources.
