T/YPACI 003-2024 Phosphogypsum-based greening soil material application technical guideline
Basic Information
Scope
Scope: This document sets out the general requirements, technical specifications, and applications of phosphogypsum-based greening soil materials. This document is applicable to the reclamation and greening of mine waste sites, backfill areas, storage yards, and spoil heaps, as well as degraded forest and grasslands, and landscaping areas; to the reclamation and greening of various types of slopes, three-dimensional greening, and high-demand anti-erosion scenarios; and to the treatment of rocky desertification lands. Main technical content: In response to the comprehensive utilization of phosphogypsum resources, and based on the spirit of relevant government documents at all levels and the achievements of research and demonstration projects, the "Technical Guidelines for the Application of Phosphogypsum-Based Greening Soil Materials" have been developed. This document consolidates the phosphogypsum-based greening soil material processing technologies verified in demonstration projects, formulates the main technical specifications and control indicators for contaminants, and provides unified and standardized guidance for the R&D, production, sales, and application of phosphogypsum-based greening soil materials. It can also serve as a reference for other regions in China in terms of phosphogypsum land utilization methods.
