T/SA 35-2025 Code of practice for disposal and resource utilization of aluminum hazardous waste

Scope

The standard stipulates the requirements for the whole process of resource utilization of aluminum hazardous waste disposal, and is applicable to qualified enterprises handling primary aluminum ash and other aluminum hazardous waste. Following the principles of "reduction, harmlessness, and resource utilization", enterprises need to obtain relevant permits and establish management and safety systems. The core processes include identification and classification (identifying the source, identifying the characteristics, and classifying the labels), collection and storage (receiving in compliance with regulations, storing in different areas, and strictly controlling the cycle), pre-treatment (screening and washing primary aluminum ash, crushing and removing iron from secondary aluminum ash), resource utilization (recovering aluminum by smelting and extracting aluminum salts by wet method), and pollution control (treating waste gas, wastewater, and tail sludge to meet standards). At the same time, it requires full-process data recording and informatized traceability to ensure standardized and verifiable operations.
