How to make briquettes for the furnace from sawdust

Searching for an economical and environmentally friendly method of heating your house in the winter? Sawdust briquettes could be the answer you’ve been searching for. These small fuel blocks use waste materials effectively and provide a sustainable substitute for regular firewood. Making your own briquettes can be a satisfying project, regardless of whether your goal is to lessen your carbon footprint or just save money on heating costs.

Compressing sawdust and other wood wastes into thick blocks that can be burned in fireplaces, furnaces, or stoves creates sawdust briquettes. This method not only gives wood waste a useful purpose that it might otherwise be thrown away, but it also offers a renewable energy source that can reduce our dependency on fossil fuels. Homeowners can enjoy effective heating solutions and support sustainability initiatives by repurposing sawdust into briquettes.

The high energy density of sawdust briquettes, which allows them to deliver a potent heat punch in a small package, is one of their main advantages. Briquettes are a great option for heating homes all winter long because they burn longer and produce more consistent heat than loose sawdust or even firewood. Furthermore, because of their consistent size and shape, they are easy to handle and store, giving homeowners the freedom to manage their fuel supply without having to deal with heavy logs.

However, precisely how are sawdust briquettes made? Although the procedure might seem complicated at first, it’s actually very simple and requires little equipment and experience to complete. With a few easy steps and an investment in a briquette press or maker, you can turn regular sawdust into a useful resource for home heating. Every step of the process, from obtaining raw materials to pressing and drying the briquettes, presents an opportunity to cut waste and practice sustainability.

Materials Needed Sawdust, Binder (e.g., starch or clay), Water
Step 1 Mix sawdust with water to moisten it.
Step 2 Add binder to the moist sawdust and mix well.
Step 3 Shape the mixture into briquettes using a mold or by hand.
Step 4 Allow the briquettes to dry thoroughly.
Step 5 Store the dried briquettes in a dry place until ready to use.

Methods of making briquettes

To begin with, you should learn how fuel briquettes are made in a factory before attempting to make them yourself. All technologies start with the same step of preparation, which is to grind and dry their raw materials. Of course, this is sawdust and larger waste from woodworking, which is processed to make briquettes. After that, the raw material is dried until its humidity index is between 8 and 10 percent.

As a point of reference. Coal dust and other agro-industrial wastes, such as husks and seed husks, can also be utilized as a source material to make eurorods.

The primary process, or briquetting, or simply pressing sawdust, starts next. There are two methods used today:

  1. Forming briquettes from sawdust on a hydraulic press.
  2. Production by extrusion.

It should be noted that the outcome of both technologies is obtained by applying intense pressure to the raw wood material, which causes it to start releasing lignin, a natural component. It binds this crumbly mass together; no additional binders are given. The only distinction is in the way the material is squeezed; in the first instance, a briquette hydraulic press is employed, producing a force between 300 and 600 bar.

The raw material heats up naturally as a result of this compression, which only helps to form a sturdy rectangular "brick." The following video demonstrates the operation of a hydraulic press-equipped briquetting line:

The extrusion method of producing sawdust briquettes can be easily understood by using a common home meat grinder or juicer as an example. The raw material is fed into the machine’s receiving hopper and then forced into a working channel with a tapering conical shape by an auger. Here it is compressed, and the briquette screw press generates a tremendous force of up to 1000 bar.

This is how Eurofirewood is pressed out by the auger.

The result is firewood made of sawdust that is hexagon shaped, heat-treated further, and then sliced with a specialized knife to a uniform size. The drawing depicts the sawdust screw press apparatus in section:

Making at home

It is obvious that investing in such potent machinery to press briquettes at home would be a financial waste. You will only be able to recover the cost if you press sawdust firewood for sale, even if you have the means and free raw materials. This indicates that the release of lignin will make it impossible to continue using the current technology. Rather than using it, do-it-yourself artisans have adapted to molding "bricks" to use alternative binders, such as:

  • Wallpaper or other cheapest glue;
  • clay;
  • paper, corrugated cardboard.

The following is how fuel briquettes are made at home in order to save money on purchasing pricey drying and pressing equipment. Sawdust is thoroughly mixed with clay after being soaked in water in a ratio of 1:10, or soaked cardboard or wallpaper adhesive can be added. The final briquette-making mixture is pressed with the hands of the operator into the mold of a hand-made sawdust press. After that, the "brick" is removed from the mold and allowed to dry outside on its own.

As a point of reference. With the use of this technology, resourceful proprietors can create briquettes out of any burning material, such as straw, paper, cardboard, leaves, seed husks, and more.

Production equipment

Basic screwdriver

This hand-made fuel briquette press is the most basic and uses a screw hand drive. After installing the perforated molding container beneath the bed and filling it with the mixture, the screw is twisted to generate pressure. It makes no sense to describe the design in detail because it is so simple to look at the image.

Because of their poor productivity, these screw machines for pressing sawdust briquettes are not very common. It takes far too long to fill the container, tighten the screw, and take out the final item. Using a homemade press with a long lever and a mechanism to push the briquettes outward, extruding "bricks" is much faster and simpler. Two molds rather than one can be welded to the bed to expedite the process.

Two molds using a manual machine

Certain artisans can take pride in possessing more sophisticated machinery. It is true that adding a hydraulic jack in place of a manual drive can enhance a manual machine and boost briquette productivity. It will take a lot of work to assemble such a machine, but the outcome will be far superior.

Apparatus with a hydraulic jack

Note: It is impossible to achieve a pressure of at least 300 bar in a homemade press, not even with the use of a hydraulic jack. As a result, without the addition of water and binders, the factory technology cannot be duplicated.

Some of the masters were able to construct a screw press and obtain briquettes of a respectable quality despite the tremendous difficulty in producing parts. The reviews left by these individuals on forums serve as proof of this. However, they all point out how expensive it is to produce the screw’s parts and the premium steel body. Once more, this cannot function without an electric drive; even the most basic computation calls for a motor with a minimum capacity of 7 kW.

Homemade briquettes – pros and cons

It is obvious why this kind of fuel is so appealing. When someone can produce their own wood or affordably purchase sawdust for briquettes, the idea of manufacturing them at home makes perfect sense. The truth is that not every heating device is designed to burn sawdust. In a traditional stove or boiler, wood chips typically burn quickly and produce little heat; in fact, up to half of them will spill into the ash pan.

A specialized boiler of the shaft type or overhead combustion is required for the successful combustion of waste wood. Although creating such a press is highly challenging, the future of pressing sawdust into fuel briquettes appears more promising.

It appears that not everything is as easy here either, and here’s why:

  1. Buying factory drying and pressing equipment is unreasonably expensive. It is cheaper to buy ready-made eurorodrov.
  2. It is possible to make a briquette press yourself and make them artisanally. But the products will be of low quality and will give little heat, and take a lot of time.

Point number two needs to be explained. Due to the inability to meet technological requirements, "bricks" that have been dried out prove to be light due to their low density. You need three times more of them for heating because their specific heat of combustion is three times lower than wood’s. It will take a lot of time and effort to complete the process. Yes, and storing that much fuel without it becoming moist is challenging.


On homemade equipment, you could theoretically make fuel briquettes by hand. However, to do this, you’ll need enough free time as well as a location for storing and drying fuel. It is also crucial that sawdust can be purchased cheaply and not need to be transported long distances. Buying a truckload of firewood makes more sense in this situation, where the event becomes completely pointless. You have the option, my dear homeowners.

Fuel: How to form sawdust briquettes

How to make fuel briquettes from sawdust

Waste is a constant in woodworking operations; sawdust and straw are two examples. They are frequently just taken to the landfill. To reduce their heating costs, a lot of private business owners start making briquettes. Let’s assume right away that specialized tools are required to obtain high-quality eurorodrov. Additionally, there are manual presses that allow people to manually form sawdust briquettes. You can easily locate videos of these productions on the internet. Upon examination, significant questions are raised regarding the viability of producing low-grade eurofuel briquettes on one’s own. It is just not possible to achieve high quality on manual presses from the outset.

Sawdust briquette production technology

Conveyor for briquetting sawdust.

There are just two steps involved in the creation of briquettes: crushing and pressing. The most important thing is an expensive, high-quality press. In the event that the press cannot generate enough high pressure, drying is added as a further production cycle. Drying will take the longest if you are making fuel briquettes by hand from sawdust. See "Pellet production" as well.

The finer the fraction of sawdust used for briquettes, the better. Sawing wood is how one obtains this raw material. The sawdust left over after wood is processed provides the majority of the production. The crushing machine’s container is filled with sawdust, which is then crushed. The raw material is then run through a press after that.

The lignin, which acts as a natural binder, is released from the press due to its extreme pressure and heat.

Since this cannot be accomplished at home, it can be used as a binder:

It is not profitable to use glue to create fuel briquettes from sawdust by hand, so this option is turned down right away. If clay is used as the binder, there will be a lot of ash left in the furnace. Ultimately, it doesn’t burn and makes up 10% of the mass in all. This means that, even without accounting for the ash from sawdust, 10 kg of clay will still be in the furnace after burning 100 kg of briquettes.

Little ash is left behind when cardboard burns, releasing heat energy. Briquettes that have soaked cardboard in place of a binder are easier to use. You will either be able to make fewer briquettes or you will need to find a location where you can place more bricks as the drying time increases.

A primer for heating pipes must be applied first in order to paint an even layer of paint. When the circuit is cold, work is done.

Finding alternate heating sources is more important than ever in the modern world, where sustainability and energy efficiency are paramount. Making sawdust briquettes for your furnace is one such solution. These briquettes provide an economical and environmentally responsible means of heating your house by making use of waste materials that would otherwise be thrown away. Sawdust can be converted into a high-energy fuel source that burns cleanly and produces little ash by compacting it into blocks. By walking you through the straightforward process of creating sawdust briquettes, this article will enable you to take the first step toward a more cost-effective and environmentally friendly heating solution for your home.

How to make briquettes with your own hands

Apply pressure using a jack.

It will be necessary to use a press to create a briquette from sawdust. Although you can purchase an already-built hydraulic press, a compressor is still required. Such equipment makes production easier and faster, but because it has a dryer, it uses a lot of electricity. The range of consumption, which varies by model, is 5 to 35 kW. There are also manual presses, in which the pressure is applied by screwing it on or using a lever. It won’t be able to adequately remove the briquettes from moisture in the first scenario. In the latter instance, the procedure is laborious.

The best choice is to use a hydraulic car jack as a press. Their minimum 2 ton load capacity varies. In order to attach the jack (upside down) to the upper beam of the bark, a sturdy metal frame must be made. In other words, the jack’s force will be applied downward, into a raw material-filled mold.

An algorithm for creating fuel briquettes by hand:

  • soak the shredded cardboard;
  • mix wet cardboard with sawdust – proportion 1:10;
  • Put the mass in the press and squeeze out the moisture;
  • take the briquettes out of the molds and dry them

Watch the video below to see for yourself how to create fuel briquettes with your hands:

Sawdust can be combined with concrete or mortar and pestle and mortar. The completed briquettes can be dried on the stove or in the sun. The fuel should have very little moisture in it. Factory briquettes, for instance, are 8–10% moisture. In domestic settings, to at least equal the 18–25% level of regular firewood. The majority of pyrolysis stoves and solid fuel boilers operate on fuels with a maximum humidity of 30%. Less heat energy will be required for the fuel to evaporate the less moisture there is in it. In order to heat the room, the dry energy carrier will thus provide more thermal energy.

When it makes sense to produce fuel briquettes

Small device for producing briquettes.

Making fuel briquettes with your own hands, as indicated in the video above, is profitable only when you have free sawdust. But even so there is not always expediency of this activity. For example, if you have your own woodworking shop that needs to be heated. It is inconvenient to just throw sawdust into the stove, and they do not burn normally. In this case, it makes sense to buy a machine and stamp on it briquettes for your needs. The quality of the products will be acceptable, and you will save money on heating. Manually making briquettes in this case is too troublesome, as you need a lot of energy carrier.

Reviews from today indicate that the most common type of propylene pipes used for circuit assembly are the modern ones.

Making the distribution of heating system pipes by hand is not difficult. Here are step-by-step instructions.

Homemade briquettes are also not the best choice for heating a private residence, and the following explains why:

  • low quality due to the use of homemade presses;
  • production requires a lot of time and effort.

That is, if we ignore the requirement that the press be produced independently as well. Briquettes might also not work out well. Bricks can easily disintegrate, which is an unpleasant surprise that can wait until they dry. When you want to make a few cubes of briquettes to occasionally heat the dacha, that’s the point of independent production. Once more, though, only if you have your own sawdust and are prepared to work on it for several days.

How to make fuel briquettes with your own hands, simple instructions

It has recently become popular to heat stoves using other, non-traditional fuel sources in addition to firewood, the traditional fuel. Fuel briquettes, for instance, are gaining popularity. Natural materials, such as sawdust and sunflower husk, compressed at a high temperature. Straw, peat, etc. Fuel briquettes, which are made entirely naturally and from biological waste, are an affordable and efficient way to soak your home or sauna.

We’ll discuss how to create fuel briquettes by hand using homemade materials in this article. To do this, you will need to learn how to properly make eurorodrova and purchase or make the necessary waste processing equipment. Creating fuel briquettes by hand will enable you to simultaneously address multiple issues:

  • get rid of waste;
  • get an effective and technological fuel for heating your home;
  • save money on firewood.

Fuel briquettes made at home can take on any shape.

Main advantages

One contemporary kind of alternative fuel is fuel briquettes. Any stove, fireplace, boiler, brazier, or barbecue can use them. Eurobriquettes are rectangular bricks or cylindrical billets that resemble firewood. Their compact size enables them to be installed in furnaces of any capacity.

What is used to make briquettes? Although wood (sawdust, shavings, and dust) is most frequently used, other materials include straw, paper, peat, coal, seed or nut husks, and even dung. Depending on the production technology employed, Eurobriquettes can have a very different composition.

In addition, every kind of raw material that can be utilized to make eurobriquettes is wholly natural. You can produce an eco-friendly product that will burn almost entirely in the furnace while producing the least amount of smoke by making fuel briquettes at home.

You can heat a house or a sauna stove with a homemade Eurobriquette. The fuel briquette burns for a long time and continuously releases a significant amount of heat because the raw material is compressed quite strongly and there is little moisture present. Those who are currently using this fuel pointed out an intriguing observation: if you melt your barbecue and cook food on it using eco-fuel briquettes, it won’t catch fire when grease gets on the briquettes.

Storage facility for prefabricated eurobriquettes produced by hand

Sawdust briquettes are a great alternative for solid fuel stoves, boilers, and fireplaces. They burn for a long time and release a lot of heat, but they ignite slowly. The high density of the pressed wood product explains this. The amount of heat produced by burning even the driest firewood—whose storage and drying took at least a year—is far less than that of briquettes.

Fuel briquettes have a humidity of 8–9%, while dry firewood has a 20% index. It turns out that the wood itself does not burn as well as a briquette made from the same wood. Because fuel briquettes don’t need to evaporate a lot of moisture during combustion, this effect results.

The briquette burns steadily, without flare-ups, sparks, or crackling, and it releases a manageable amount of smoke during combustion. Putting such fuel into the stove is very convenient because every product has a consistent, uniform shape.

A small tip: to maintain smoldering, tightly combine all eco-fuel in the firebox. Alternatively, place fuel briquettes in the firebox at a certain distance from one another if you need to create an intense fire with high heat output.

Putting in the firebox some homemade, environmentally friendly fuel briquettes

As with any product, fuel briquettes have drawbacks.

  • First of all, it is worth noting that they are very vulnerable to moisture, so they are sold in cellophane packaging.
  • Briquettes are not able to resist mechanical effects, especially products made by RUF technology. not burned on the outside.
  • If you want to establish the manufacture of such things at home, it will cost you a lot of money, although on the long run, the benefit will certainly be there. The fact is that you will have to purchase a shredding unit, a dryer and a press machine to carry out the entire cycle of work with raw materials. With the right equipment to establish artisanal production of fuel briquettes will be possible even in your own garage.

Equipment and raw materials

With a variety of human waste materials, you can make fuel briquettes by hand. Basically, you can use anything that burns normally. Which domestic waste can be converted into a full raw material?

  • First of all wood, sawdust and shavings, wood dust, leaves and branches of trees. The species of wood does not play a primary role, but it is better that the sawdust is birch, oak, from alder or aspen.
  • Straw left after wheat or corn harvesting.
  • Cardboard and paper. Fuel briquettes from paper with their own hands to make much easier than from wood, but only the paper version will burn faster.
  • Good, but rare raw materials can be residues and husks of seeds, nut shells.

Because briquettes can have varying compositions, the mixture’s adhesive properties can also vary. Some briquettes have clay added to them to aid in binding the elements, typically in a 10 to 1 ratio depending on the raw materials used.

Sawdust from wood may be the best raw material.

Special tools are required to make fuel briquettes at home. Because the technology for producing fuel briquettes is essentially straightforward, you can order an entire line for home production at once, applying to a specific company, and assembling the equipment in parts.

Three production stages form the foundation of the entire technology:

  1. The first stage involves the initial preparation of raw materials. The available waste should be crushed, crushed to the necessary consistency so that the composition of the mixture is homogeneous.
  2. The second stage involves bringing the mixture to a finished state by drying method. On the drying machine, the raw material is rid of moisture.
  3. The third stage involves the manufacture of products, here is the pressing of fuel briquettes on a special machine under high pressure and temperature.

Using a screw press to process raw materials

You must select the appropriate machine for your raw material at each stage (crusher, dryer, and press).

The process of making fuel briquettes by hand is generally similar to that of industrial production, with the exception that there are no artificial standards for product quality and the completed goods are not sealed in a hermetic container.

One other distinction with home production is that, in theory, the dryer can be left off the line. Briquettes and raw materials can be naturally dried in the sun. By the way, you might not need a crusher if the raw material is already-made sawdust or seed husks.

Expert artisans create their own presses according to their requirements and capacities. These days, there are no restrictions on information access, so drawings of any kind of device can be found on the network for free. Your own press can be built in accordance with the drawings, allowing you to create a special briquette product that burns flawlessly in stove furnaces.

How to build a press machine can be recommended by friends who have experience with these types of artisanal or industrial production methods. Options include percussion-mechanical, hydraulic, and auger.

An apparatus for making fuel briquettes

To set up your equipment, you will need a room that is reasonably sized. You will need to store all of the equipment, raw materials, and finished goods in it. Make sure you have adequate ventilation to ensure that the drying process is comfortable and that the briquettes have low humidity. Electricity will be needed to connect the machines, and since we produce fuel, we should remember to take precautions against fire.

Making sawdust briquettes could be the answer you’ve been looking for if you want to heat your house during the colder months in an economical and environmentally responsible manner. This technique not only makes use of waste material but also offers a sustainable substitute for conventional fuel sources.

Not only does compacting sawdust into briquettes minimize waste, but it also produces a handy and effective fuel source for your fireplace or furnace. When compared to traditional firewood, these briquettes burn cleanly and produce less smoke and ash, which makes them a great option for homeowners who care about the environment.

Furthermore, creating sawdust briquettes is a reasonably easy process that needs little equipment. Anyone can make their own briquettes at home and lower their carbon footprint and heating costs with the correct equipment and some practice.

Furthermore, sawdust briquettes can help improve the insulation in your house. They produce steady heat as they burn at a steady, regulated rate, which aids in preserving a comfortable interior temperature. Over time, this may result in lower heating expenses and energy consumption.

To sum up, creating sawdust briquettes is an economical and environmentally friendly way to heat your house. It uses waste material, but it also offers a productive and affordable substitute for conventional fuel sources. You can enjoy a warmer home and lessen your environmental impact by implementing this method into your heating routine.
