Characteristics and Prospects of Vermicast Sludge for Resource Utilization

Vermicast sludge, the fecal of earthworms fed on sewage sludge, has important ecological and economic value. An up-to-date review of the characteristics of vermicast sludge was provided, including physicochemical properties, microbiologic properties, antimicrobial activity, plant nutrient composition and growth regulating hormones, and the research and development situation and resource utilization prospects of vermicast sludge products were analyzed. Furthermore, the biochemical mechanism of in-depth research into vermicast sludge was proposed, for the sake of broadening the scope of application of vermicast sludge, formulating standards and regulations related to the administration of vermicast sludge products, and constructing vermicast sludge eco-industrial chain, which was also proved as an important means for the realization of coordinated development of vermicompost economic cycle.
