This biochar fertilizer line utilizes high-temperature pyrolysis technology to convert agricultural organic waste into high-value-added biochar fertilizer, achieving the recovery and utilization of combustible gases and the self-circulation of energy during the production process. The plant can operate continuously for extended periods, possessing core advantages such as zero pollution, zero emissions, low labor requirements, huge production capacity, and significant energy conservation and emission reduction, representing cutting-edge technology in the field of organic solid waste resource utilization.

This biochar-based fertilizer production line is scientifically designed and widely compatible, suitable for the co-processing and fertilizerization of various organic and biomass raw materials. The materials used are diverse, mainly including two categories: first, raw materials for biochar preparation, such as agricultural residues like rice husks, wheat straw, and corn stalks; forestry processing waste such as sawdust, wood chips, and branches; and other biomass rich in lignin, such as coconut shells, bamboo chips, and fruit shells; second, raw materials for composting fermentation, such as livestock and poultry manure like chicken, pig, and cow manure; pre-treated kitchen waste or biogas residue; and biomass waste such as distiller's grains, vinegar residue, mushroom residue, and traditional Chinese medicine residue. By co-processing these two major categories of materials, this production line enables the efficient resource utilization of agricultural, forestry, and urban/rural organic waste.
