For large-scale farms, the treatment of livestock and poultry manure has transformed from a mere environmental burden into a resource utilization challenge with immense economic benefits. A scientifically designed and efficiently operating customized organic fertilizer production line can not only completely solve pollution problems but also transform manure into marketable organic fertilizer, achieving both environmental and economic benefits. The key to success lies in “customization”—it must closely revolve around the manure characteristics, site conditions, investment scale, and product goals of the farm, creating a seamless conversion pipeline from “waste” to “resource.”
