The organic waste used in organic fertilizer equipment primarily consists of corrosive materials, so we must employ enclosed transport vehicles for collecting and transporting these wastes. These organic wastes easily emit foul odors, which not only cause environmental pollution but also pose significant harm to human health. Therefore, we must promptly collect and utilize these organic wastes.

Although by-products such as rice husks and sawdust do not produce foul odors, they generate dust during the unloading of raw materials. Additionally, when using a crusher to process rice husks, dust and steam are also generated during the transfer of husks to storage tanks, around the crusher, and when handling crushed husks.

During the shredding and pruning process, using a shear-type shredder generally produces little to no dust. However, when shredding and pruning with a high-speed rotary crusher combined with air conveyance, a significant amount of dust and noise is generated. In mixing equipment, when various raw materials are fed into the mixer, especially during the discharge of low-moisture compost return material and mixed raw materials, odors and dust are also produced.

During the fermentation process in organic fertilizer production equipment, the decomposition of organic matter generates odors primarily consisting of ammonia. The introduction of various raw materials into one-time fermentation facilities, the discharge of compost from these facilities, and repeated operations in secondary fermentation tanks all contribute to the generation of odors and dust. The decomposition of organic matter causes temperature increases in raw materials, resulting in substantial amounts of water vapor.

During the repeated operation process, foul odors, water vapor, high temperatures, and dust mix together. The water vapor generated inside the fermentation chamber causes the entire chamber to appear as a white mist. The foul odors and water vapor produced during fermentation significantly decrease as the primary fermentation phase concludes and nearly disappear by the end of the secondary fermentation. As the moisture content in the compost decreases, dust is subsequently generated. In the repeated use of secondary fermentation facilities, both water vapor and dust are simultaneously produced.
