Introduction
Standard Background and Industry Significance
With the advancement of the national dual-carbon strategy, the green transformation of the non-ferrous metal industry has accelerated. As the first special evaluation standard for green factories in the germanium industry, YS/T 1702-2024 fills the gap in green manufacturing standards in the field of rare metals. The standard takes typical products such as zone melting germanium ingots and high-purity germanium tetrachloride as the objects, and constructs an evaluation system covering the entire life cycle.
Core evaluation index system
| First-level index | Weight | Key control point |
|---|---|---|
| Basic requirements | One-vote veto | Compliance operation, no major accidents, credit record |
| Infrastructure | 15% | Building energy saving, permeable ground ≥30%, independent storage of hazardous waste |
| Energy resources | 20% | Energy consumption reaches GB29447-2022 Level 3, waste heat recovery rate |
Analysis of key technical requirements
5.4 Energy resource input
Mandatory requirement: the comprehensive energy consumption of germanium concentrate processing is ≤3.8tce/t-Ge (Level 3), and it is recommended to use a proportion of recycled germanium raw materials ≥30%. Energy efficiency limit requirements for key equipment:
- Air compressor: ≥GB19153-2019 Energy efficiency level 3
- Transformer: ≥GB20052-2020 Energy efficiency level 3
Implementation suggestions
Solutions to typical problems
Case: The recovery rate of hydrogen chloride tail gas in a certain enterprise is less than 60%. The recovery rate can be increased to more than 90% by adding a three-stage recovery system of graphite falling film absorber, while meeting the atmospheric emission requirements of 5.6.1.
Certification preparation path
- Complete four-system certification (quality/environment/occupational health/energy)
- Establish a greenhouse gas emission accounting system (GB/T32150)
- Implement clean production technology transformation (reference T/CNIA0100)
