Abstract: With the vigorous development of sericulture, the traditional labor-intensive small-scale silkworm rearing has been progressively transformed into a large-scale mechanized system. Consequently, silkworm factories can produce cocoons continuously throughout the year. However, this intensive production pattern generates a substantial amount of silkworm excrement. If not managed properly or disposed indiscriminately, silkworm excrement can lead to severe environmental pollution. In recent years, increasing attention has been paid to the comprehensive utilization of this bioresource. Numerous studies have explored its potential in a wide range of applications. This review systematically summarizes current research on silkworm excrement utilization, particularly focusing on its fundamental characteristics, key technologies, and application areas. Future efforts should aim to promote efficient resource recycling and support the development of sericulture.
