Introduction
GB/T 33858—2017 Standard Overview
This standard provides a comprehensive guidance framework for circular economy evaluation in the aluminum industry and is applicable to alumina and electrolytic aluminum production enterprises. By establishing a scientific evaluation index system, it helps enterprises achieve efficient resource utilization and environmental protection.
Circular economy evaluation index system
| Industry | Specific indicators | Indicator unit | Indicator reference value | Indicator type |
|---|---|---|---|---|
| Alumina industry | Energy output | 3.23 | Required | |
| Alumina industry | Alumina conversion rate | % | 85.00 | Required |
| Water Resources Output | t/m3 | 0.67 | Required | |
| Alkali Output | t/t | 12.00 | Required | |
| Aluminum Electrolysis Industry | Energy Output | t/tce | 0.61 | Required |
Circular Economy Index Calculation Method
The calculation formula of the circular economy index (PI) of the aluminum industry is as follows:
PI = (1/(n + m)) * (∑(R P_i / R P_b_i) + ∑(R R_j / R R_b_j)) * 100
- n: number of resource output indicators
- m: number of resource recycling rate indicators
- R P_i: the i-th resource output indicator value
- R P_b_i: the benchmark value of the i-th resource output indicator
- R R_j: the resource recycling rate indicator value
- R R_b_j: the benchmark value of the resource recycling rate indicator
Evaluation level division
The circular economy evaluation level of the aluminum industry is divided into three levels:
| Evaluation level | Level requirements |
|---|---|
| ★★★-level circular economy enterprise | Meet the basic requirements and PI ≥ 90 |
| ★★-level circular economy enterprise | Meet the basic requirements and PI ≥ 80 |
| ★-level circular economy enterprise | Meet the basic requirements and PI ≥ 70 |
Implementation suggestions
To ensure the effective implementation of the standard, it is recommended that:
- Establish a sound circular economy management system
- Strengthen resource measurement and monitoring capabilities
- Promote technological innovation and upgrading
- Carry out circular economy training and publicity
- Encourage cooperation and resource sharing among enterprises
