Utilization of Forest Residues: Sawdust

Green spaces represent a primary source of natural resources, particularly wood. Wood processing and manufacturing constitute a well-developed sector of industry. A significant quantity of sawdust and wood waste accumulates as a result of activities in carpentry, timber, sawmills, furniture, and parquet factories. Much of this wood waste is stored outdoors.

While some sawdust is burned in boilers in its raw form, producing briquettes and pellets from sawdust is considerably more profitable.

Manufacturing briquettes from sawdust provides solutions for:

• Addressing the global challenge of harmful emissions into the atmosphere.
• Enhancing environmental quality.
• Cleaning up areas where wood processing occurs.
• Other benefits.

When considering efficiency and cost-effectiveness, which is superior: briquette manufacturing or pellet production? Let’s examine the advantages and disadvantages.

Should we produce briquettes or pellets?

Pellets require more expensive and complex machinery. Furthermore, the repair and reconditioning of pellet manufacturing equipment can be costly and complicated, typically necessitating service from the equipment manufacturer.

To produce briquettes, you need a BriqTech mechanical briquette press, which is approximately 30% cheaper compared to machinery for pellet production while maintaining similar performance.

The raw material for pellet production must often be crushed to a smaller granulate size, which can require additional energy. This implies that additional grinding and removing impurities is necessary. In contrast, larger raw material sizes do not pose a challenge in briquette production.

When it comes to the transportation and storage of pellets, they are fragile and can lose their shape, becoming crushed or crumbled. Conversely, briquettes maintain their integrity during handling, and their burning capacity remains unaffected by crumbling.

The production cost of pellets is significantly higher than that of briquettes, attributed to the more expensive machinery and the necessity for skilled personnel. Also, pellets have a narrower market compared to briquettes, owing to their use primarily in pellet-fired thermal power plants, whereas briquettes can be utilized in a variety of applications, including solid fuel industrial thermal plants and directly in fireplaces, stoves, etc.

The generation of bio-fuel from biofuel briquettes and/or pellet production presents substantial revenue opportunities and promising prospects for the future.

Manufacturing and utilizing renewable energy for personal needs, as well as producing biomass fuel (e.g., pellets and briquettes) for commercial purposes, forms a crucial part of projects funded by the European Union. The Romanian State may encourage these initiatives by providing financial support to both producers and consumers of green fuel, thereby reducing reliance on imported natural gas and promoting the use of renewable, environmentally friendly fuels.

Through briquette production, we can provide bio-energy solutions for both private residences and agro-industrial enterprises.

Our company actively participates in the European market, offering commercialization of pre-pressed sawdust briquettes, briquetting equipment for briquette production, and complete pellet production lines, including delivery, assembly, service, maintenance, post-warranty solutions, and spare parts.
