Introduction
Interpretation of the National Standard of the People's Republic of China GB/T 33874—2017
1. Background and significance of the formulation of the standard
GB/T 33874—2017 is China's first national standard for environmental protection requirements for toner manufacturing processes and products. With the rapid development of the printing consumables industry, the environmental pollution problem generated during the toner production process has become increasingly prominent. The formulation of this standard aims to standardize the environmental protection requirements of the entire toner manufacturing process, reduce the emission of harmful substances, and promote the sustainable development of the industry.
2. Standard framework and main contents
| Chapter contents | Main requirements | Implementation focus |
|---|---|---|
| Producer responsibility | Establish a waste powder recycling system, conduct environmental impact assessment, and obtain GB/T19001 and GB/T24001 certification. | Enterprises must pass quality management system and environmental management system certifications and conduct regular environmental monitoring. |
| Raw material requirements | The use of hexavalent chromium, nickel compounds and carcinogenic aromatic amine dyes is prohibited, and resins must comply with GB/T28032 requirements. | Supply chain management requires strict screening of raw material suppliers that meet environmental protection requirements. |
| Manufacturing process control | The production line is sealed without leakage, dust emission complies with GBZ2.1, noise complies with GB3096, and wastewater treatment meets standard requirements. | The production workshop needs to install dust removal equipment and regularly monitor atmospheric pollutants and noise levels. |
3. Implementation case and technology evolution analysis
Take Zhuhai Tianwei Feima Printing Consumables Co., Ltd. as an example. The company successfully achieved the green transformation of toner production by establishing a waste toner recycling system and using environmentally friendly raw materials. Its experience shows that through technological innovation and process optimization, enterprises can improve production efficiency while meeting environmental protection requirements.
4. Comparison of key data and standards
| Chemical substances | Benzene limit | Styrene limit | TVOC limit (mg/m³) | ||
|---|---|---|---|---|---|
| Benzene | 1 | 40 | 500 (before June 1, 2018) | 360(2018.06.01—2019.12.31) | 300 (from January 1, 2020) |
5. Implementation recommendations
Recommendations:
- Enterprises should formulate detailed environmental protection policies and objectives.
- Establish a complete waste powder recycling system to promote resource recycling.
- Perform regular environmental monitoring and keep relevant records for inspection.
- Cooperate with certification bodies to ensure compliance with GB/T19001 and GB/T24001 standards.
