This invention discloses a composting method and intelligent composting system based on garden waste. The composting method based on garden waste provides a homogeneous and optimized material basis for efficient fermentation through intelligent pretreatment and dynamic formulation of raw materials. During fermentation, a three-dimensional sensor network is deployed and a synchronized digital twin model is constructed. The model is used to predict the future evolution of internal temperature, oxygen, and microbial activity within the compost pile. The degree of composting is intelligently determined by a multi-source information fusion model. The matured material undergoes multi-stage screening to produce a series of products, and a unique traceability code links the entire process to a digital archive, achieving quality traceability. This invention also provides an integrated system for implementing this method. This invention achieves predictive intelligent control and clean production in the composting process, significantly improving processing efficiency, product quality, and resource utilization, while effectively controlling operating costs and environmental pollution.
