The large-scale generation and accumulation of bulk industrial solid waste in China have significant ecological and environmental impacts. Therefore, strengthening the multi-level recycling of bulk industrial solid waste to reduce stock and minimize increment becomes crucial for ecological civilization and the construction of a Beautiful China. This study analyzes the prominent challenges faced by the comprehensive utilization of bulk industrial solid waste in China. Drawing on international advanced concepts and the current progress in circular economy research, it proposes a new concept of "Earth macro-cycle" and elaborates on its background and core elements. The study focuses on creating new paradigms in "Earth macro-cycle" research, including the reconstruction of bulk industrial solid waste through simulated natural mineralization and mine backfilling, transformation of bulk industrial solid waste into soil-like materials for ecological reuse, ecological balance and risk control of historically accumulated bulk industrial solid waste stockpiles, and intelligent decision-making and management system platform for the "Earth macro-cycle." By precisely applying the concept of "Earth macro-cycle," the study aims to build a circular green production model, establish an "Earth macro-cycle" model for hard-to-dispose industrial solid waste, and drive the creation of a circular society through systematic design. This will gradually enable the large-scale disposal and ecological return of bulk industrial solid waste.
