| Product Background |
Biomass energy, as a clean and renewable energy source, has become a key alternative to fossil fuels amid global energy shortages and increasing environmental protection demands. The 8 mm biomass wooden pellet is a typical solid biomass fuel product processed from abundant and low-cost biomass raw materials. Its raw material sources mainly include agricultural and forestry wastes such as wood scraps, sawdust, crop straws (like corn stover, wheat straw), forest residues (such as branches, tree barks), and even discarded wooden furniture or construction waste wood—materials that would otherwise be incinerated or discarded, causing environmental pollution. In the production process, the 8 mm biomass wooden pellet does not require any chemical additives. It undergoes four core physical processing steps: first, raw materials are crushed into small particles (usually 4-8 mm in size) to meet the feeding requirements of granulation equipment; second, if the moisture content of the crushed raw materials exceeds 20%, a drying process is applied to reduce the moisture content to below 20% (and even as low as below 10% for high-quality products), which is critical for improving combustion efficiency and preventing mold during storage; third, the dried and crushed raw materials are pressed into cylindrical pellets with a diameter of 8 mm through biomass granulators (relying on the pressure between pressure rollers and ring molds); finally, the hot pellets (generated by friction during pressing) are cooled to room temperature and then packaged for storage and transportation. The 8 mm specification is not arbitrary—it is a mainstream size in the biomass pellet market. Compared with larger-sized biomass fuel blocks (e.g., 80 mm in diameter), 8 mm pellets have a larger specific surface area, enabling more sufficient combustion and avoiding incomplete combustion caused by poor heat transfer in large blocks. Meanwhile, compared with smaller-sized pellets (e.g., 4 mm), 8 mm pellets have higher mechanical strength, which reduces breakage during transportation and storage, ensuring stable product quality. |
| Product Features |
High Density for Easy Storage and Transportation: The raw materials of biomass have a low bulk density of only 0.1—0.13 t/m³, which is difficult to store and transport efficiently. After processing, the 8 mm biomass wooden pellet has a bulk density of 1.1—1.3 t/m³. This significant increase in density reduces storage space occupancy and lowers transportation costs (e.g., more pellets can be loaded per truck, reducing unit transportation fees). Low Moisture Content for High Combustion Efficiency: The product strictly controls moisture content below 20% (and often below 10% for premium grades). Low moisture content avoids heat loss caused by water evaporation during combustion, ensuring a stable calorific value. Its calorific value can reach 3600—5000 kcal/kg, which is close to that of coal, meeting the heat demand of various heating and industrial scenarios. Clean and Low-Pollution Combustion: During combustion, the 8 mm biomass wooden pellet produces almost no sulfur dioxide (a major cause of acid rain) and significantly reduces greenhouse gas emissions. According to research by the Biomass Thermal Energy Council (BETC), compared with heating oil, biomass wooden pellets can reduce greenhouse gas emissions by 65%—100%, fully complying with global environmental protection standards for low-carbon energy. No Chemical Additives and Recyclable Residues: The entire production process relies solely on physical extrusion without adding any toxic or harmful chemical substances, ensuring safety during combustion. After full combustion, the remaining ash (with almost no carbon content) can be used as organic fertilizer for agricultural production, realizing the "from waste to energy to fertilizer" circular economy chain. Uniform Size for Stable Application: With a fixed 8 mm diameter and regular cylindrical shape, the product can be uniformly fed into combustion equipment (such as boilers, stoves) without clogging the feeding system. This uniformity also ensures consistent heat release during combustion, avoiding unstable temperature fluctuations in industrial production or domestic heating. |
| Related Products | In the biomass energy and bio-based material field, customers interested in 8 mm biomass wooden pellets may also pay attention to other complementary or similar products. These include larger-sized biomass fuel blocks (with diameters up to 80 mm, suitable for scenarios requiring long burning time without frequent feeding), biomass briquettes (compressed into irregular blocks, often used in industrial boilers with larger feeding ports), bioethanol (a liquid biomass fuel used in transportation or industrial heating), biodiesel (another liquid biomass fuel applicable to diesel engines), and biomass wood chips (unpelletized small wood particles, suitable for large-scale industrial furnaces with direct feeding systems). Additionally, products in the bio-based material field, such as bio-based PLA (polylactic acid, used in packaging and textiles) and bio-based PHA (polyhydroxyalkanoates, a biodegradable plastic), may also attract customers who focus on sustainable and eco-friendly products.
