The article aims to explore the advantages of Biomass Briquettes and also understand the challenges in their production. Briquettes are derived from organic materials such as agricultural residues, wood chips, sawdust, or other biomass waste and offer several advantages that make them sustainable and efficient energy sources.
Tiantai are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.
Firstly, biomass briquettes provide a renewable energy option. Unlike fossil fuels, which are finite and contribute to greenhouse gas emissions, biomass is derived from organic materials that can be replenished through sustainable practices, such as reforestation and agricultural waste management.
Secondly, biomass briquettes are cost-effective. Since they are made from waste materials that would otherwise be disposed of, the production costs are relatively low. Biomass briquettes can be produced locally, reducing transportation costs and creating opportunities for rural communities to generate income.
Moreover, biomass briquettes have a higher energy density compared to raw biomass. This makes them easier to store, transport, and handle, making them a more practical option for energy production.
Furthermore, biomass briquettes contribute to waste management by diverting organic waste from landfills and reducing the environmental impact associated with open burning.
Finally, biomass briquettes are versatile and can be used for various applications such as heating, cooking, and electricity generation, providing a sustainable alternative to traditional fossil fuels.
In conclusion, biomass briquettes offer numerous advantages, including renewability, cost-effectiveness, higher energy density, waste management benefits, and versatility, making them a promising solution for addressing energy and environmental challenges.
Challenges in the production of briquettes
The production of biomass briquettes also comes with its own set of challenges that must be addressed to ensure its widespread adoption and effectiveness as a sustainable energy source.
One major challenge in biomass briquette production is the variability of feedstock. Biomass feedstock can come from a variety of sources, including agricultural residues, forestry waste, and municipal solid waste. However, the composition and quality of these feedstocks can vary significantly depending on factors such as seasonality, geographical location, and harvesting methods. This variability can affect the efficiency and consistency of the briquette production process, requiring careful selection and preparation of feedstock to ensure optimal results.
Another challenge is the moisture content of the feedstock. High moisture content can hinder the briquetting process by reducing the density and energy content of the briquettes, as well as increasing the energy required for drying and processing. Proper moisture management techniques, such as drying or pre-treatment, are necessary to ensure the quality and efficiency of biomass briquette production.
Furthermore, the density and physical properties of biomass feedstock can vary widely, posing challenges in the briquetting process. Some feedstocks may contain high levels of lignin, which acts as a natural binding agent and facilitates briquette formation, while others may require the addition of binders or additives to improve cohesion and strength. Finding the right balance of feedstock composition and binder content is essential for producing high-quality biomass briquettes.
Additionally, the equipment and technology used in biomass briquette production can be costly and require specialized knowledge and skills for operation and maintenance. Small-scale producers, particularly in rural areas, may face barriers to accessing suitable equipment and technical expertise, limiting their ability to participate in briquette production initiatives.
In conclusion, while biomass briquettes offer a promising solution for sustainable energy production, overcoming challenges such as feedstock variability, moisture management, feedstock characteristics, and technology limitations is essential to realizing their full potential and promoting their widespread adoption as a renewable energy source. Collaboration between stakeholders, investment in research and development, and supportive policies and incentives are needed to address these challenges and promote the growth of the biomass briquette industry
Biomass energy refer to the energy from plants and animals, mainly composed of organic matters. It is the chemical form of solar power deposited in organisms. Generally, it has 4 sources, agriculture biomass, forestry biomass, urban solid waste, and energy crops.
These biomass materials can be molded into pellets or briquettes under high pressure. They are called biomass molding fuel. These biomass fuels has high density and heat efficiency, widely applied in heating stoves, boilers and power plants.
Biomass fuels have high heat value. For wood pellets, the heat value is - kcal/kg. For crop pellets, the heat value is - Kcal/kg. Although they don't reach the coal’s kcal/kg, with less ash and slag residues, their heating effects are similar with medium coals.

According to industrial analysis, the biomass fuels contains high volatiles content. In terms of corn stalks and sawdust, their volatiles content can be 70-90%. This means biomass fuels have high ignitability.
Burning coals will generate large quantities of NOx, CO2, SO2, as well as suspended particulate matter, ash and slag. They are pollutant to the environment and have been restricted in many placed.
Burning biomass fuels can significantly reduce CO2 emission. As biomass contains little sulfur, there is no SO2 emission. Besides, biomass fuels has less fly ash, slag, or heavy metal discharge. Therefore, biomass fuel is known as clean and green energy.
Biomass energy is the world’s 4th largest energy. As estimated by biologist, the land generate 100-125 billion tons of dry biomass every year, and the ocean generate 50 billion tons of dry biomass. Farms and forestry can provide abundant biomass resources that we can make use of.
In this regard, biomass energy is a renewable energy with large output and stable supply. Meanwhile, as the biomass materials cost low, and the manufacturing cost is much lower than coal and oil, it has significant price advantages and promotes more easily.
To make use of biomass energy, we usually mold the bulky materials into briquettes or pellets. Pellet mill and briquette press is used to mold the biomass materials with high pressure and temperature. They can soften the raw materials and squeeze them into a die or mold, so as to increase the density dramatically.
The molding process includes raw material crushing, drying, molding, cooling and packing, etc. First, we need to crush the raw material to reduce the size to under 5mm, then lower the moisture content to 15-20% with a drum dryer or in the sunlight. After that, we can use the molding equipment to make biomass fuels.
According to different molding structure, the molding equipment can be classified into 4 types: stamping briquette press, screw extruding briquette machine, ring die pellet machine, and flat die pellet machine.
Although biomass resources are abundant, they distributed unevenly all over the world. With irregular shapes and low density, the biomass materials usually take up large places, costing high for storage and transportation.
Taking rice husks for example, its natural stacking density is only 83-160kg/m3. The fixed carbon content is 10-15%, and the heat value is kcal/kg, equal to half of 1kg coal. So the energy density is rather low. To mold it into briquettes or pellets can increase the density to —kg/m3. But the molding equipment and process will increase the use cost.
These defects hinder the application of biomass fuel. Currently, to increase the energy density is a key project in the development of biomass energy.
Biomass materials usually contains high alkali metal (Na、K、Ca、Mg) and metalloid content (Si、S、Cl、P), which lower the ash fusion point and cause ash and slag deposition. They not only impair the heat exchanging efficiency, but cause corrosion and abrasion to the boilers.
So it is usually added with Al2O3, MgO and kaolin or other biomass materials with high ash fusion point (like rice husks) to increase the softening temperature, increase the ash fusion point, and lower the burning temperature.
Most biomass molding fuels has poor water resistance. Once contacting with water, the biomass pellets with become damp and loose, and crumble into powders. Therefore, the wood pellets must be packaged in water-proof bags and stored in dry rooms above the ground.
Although the biomass molding technology has developed for decades of years and the equipments have matured, there are still have many deficiencies, such as high power consumption, quick wear of the die and roller, short working life, and too simple molding process.
