Sawdust blocks

Types of sawdust blocks

Wood sawdust blocks are compressed blocks of sawdust that are commonly used as a fuel source or for other purposes. Here are the main types:

• Wood sawdust blocks

These are blocks made from wood sawdust, which is the residue produced by cutting wood. Wood sawdust is a commonly used material for making hardwood sawdust bricks due to its availability and ease of compression. It can be obtained from different types of wood, including softwoods like pine and hardwoods like oak and maple. The blocks are made by compressing the sawdust at high pressure, usually with the help of a binding agent like natural lignin or other binding materials. The compression process ensures the sawdust particles stick together, forming solid blocks. These blocks are popularly used as fuel sources due to their high energy content and clean-burning characteristics. They are commonly used in biomass boilers, stoves, and industrial furnaces as a renewable alternative to traditional fuels.

• Sawdust briquettes

These are blocks made from sawdust and other biomass materials. Like wood sawdust blocks, compressed sawdust blocks are produced by compressing dry sawdust under high pressure. However, in addition to sawdust, they can also contain other biomass materials like coffee husks, rice husks, peanut shells, and coconut shells. The mixture of sawdust and these other materials is subjected to high compression to form uniform blocks. Sawdust briquettes are also popular as fuel sources due to their high energy content and efficient burning properties. They are commonly used for heating and cooking in households and commercial settings. Additionally, their composition with other biomass materials makes them a more sustainable fuel source, and they are usually preferred for their lower emissions.

• Charcoal sawdust blocks

Charcoal sawdust blocks are made from carbonized sawdust, which is commonly known as charcoal. Sawdust is first carbonized in a kiln or using other carbonization methods to remove the volatile components, leaving pure carbon. The resulting charcoal is then mixed with a binder, usually water or natural starch, and compressed under high pressure to form charcoal sawdust blocks. Due to their high carbon content, these blocks burn hotter and cleaner than regular wood sawdust blocks. They are commonly used as a fuel source in industrial settings, for grilling and barbeques, and in water treatment plants.

Functions and features of sawdust blocks

There are several functions of sawdust blocks. The main one is as an alternative to firewood. The blocks are made from sawdust waste, which would otherwise be thrown away.

Features of sawdust blocks include:

• Moisture content: Sawdust blocks have a low moisture content. They are made by compressing sawdust waste at high pressure and temperature. This makes them burn hotter and for longer compared to firewood. The low moisture content also makes the blocks lightweight. They are easy to transport and store.
• Calorific value: These blocks release more heat than firewood. This is because they have a high calorific value. They are a popular choice for people who use firewood to heat their homes. The blocks burn slowly and evenly. They produce a consistent flame that lasts for a long time. This helps to keep the home warm without having to add more blocks to the fire.
• Ash content: Sawdust blocks have a low ash content. This is beneficial to people who use firewood for cooking. The ash is easy to remove from the fireplace, and the blocks need to be replaced less often.
• Compression ratio: This is the rate at which sawdust waste is compressed into blocks. The higher the compression ratio, the more solid the blocks will be. They will also burn for longer. For example, eco-friendly sawdust blocks for burning have a compression ratio of 10:1. This means 10 kilograms of sawdust are compressed into 1 kilogram of blocks.

Applications of Sawdust Blocks

• Building Construction

Sawdust is a significant construction material for developing a solid, stable, and warm building. It's utilized in wall cavities to provide insulation. Sawdust blocks guarantee the inside atmosphere remains cozy without the need for additional heating or cooling. Sawdust blocks are installed on roofs, floors, and walls to ensure the building is well insulated. It can also be used on the exterior as a sheathing.

• Animal Bedding

Sawdust from clean, untreated wood can be compacted into sawdust blocks for mushrooms use as animal bedding. Some livestock, like horses, and small animals, such as rabbits, chickens, and guinea pigs, require sawdust blocks for bedding.

• Sustainable Waste Management

Sawdust blocks are also used in sustainable waste management practices. The blocks are used as a substitute for conventional firewood. They are burned in stoves and fireplaces as fuel. Sawdust is burned with a lower amount of ash, which makes it easier to clean. Since it burns cleanly, it doesn't produce a lot of harmful fumes and particulates. Sawdust is also used to make charcoal blocks, which can be used for grilling and cooking. Additionally, the ash residue from burned sawdust blocks can be used as a natural fertilizer.

How to choose sawdust blocks

When looking for sawdust fuel blocks for sale, it is important to consider several factors. This is because the demand for these blocks is increasing due to their eco-friendliness and affordability. Therefore, knowing what to look for is essential to ensure one gets blocks that will meet their customers' needs. Here are some of the factors to consider when choosing sawdust fuel blocks:

• Moisture Content

It is important to check the moisture content of the fuel blocks. The ideal moisture content should not be more than 10%. Low moisture content means that the blocks will burn efficiently. It also means that the blocks will store well without developing molds.

• Heat Emission

The heat emission of the blocks varies depending on the binding agent used. Blocks with high heat emission are loved by many customers because they offer value for the money. Therefore, it is important to check the heat emission. Blocks with 18.5 MJ/kg are a good option for customers who want to heat a small space.

• Compression Rate and Density

The density and compression rate of the blocks will determine their performance. High-density blocks burn for a longer time compared to low-density ones. Also, the compression rate shows how the blocks will hold up when being transported. Denser and higher compression blocks are more durable and will not break or crumble when being transported.

• Ash Residue

It is important to choose blocks with low ash residue. Low ash residue means that the blocks will burn efficiently. It will also make them easy to clean and maintain. Therefore, when buying the blocks in bulk, one should check their ash content before stocking them.

• Size and Shape

Sawdust blocks vary in size and shape. Some are large, while others are small. They also come in different shapes, such as cylindrical and square. It is important to get blocks in various sizes and shapes. This will allow customers to choose what is suitable for their stoves.

• Storage Space

Size and shape contribute to how much storage space the blocks will occupy. Sawdust blocks are the same as traditional wood. Therefore, they take up less space. However, if the blocks are compacted tightly, it may require more space for storage.

• Stock Availability

Another important factor to consider is the availability of the stock. It is important to stock the blocks in large quantities to prevent running out of stock when the demand is high. Also, stocking the blocks in large quantities will enable one to buy the blocks at a cheaper rate, which will increase the profit margin.
