Zinc Recycling in Vietnam: An Inevitable Trend in the Circular Economy

1. Overview of Zinc Recycling in Vietnam

Zinc is a crucial non-ferrous metal known for its high corrosion resistance, primarily used in steel galvanization and alloys. In recent years, the demand for zinc in Vietnam has surged, particularly in the construction, automotive, electronics, and heavy industries. Consequently, zinc recycling has become a sustainable solution to reduce raw material import costs and mitigate environmental pollution.

2. Primary Sources of Zinc Scrap in Vietnam

• Industrial Sources: Steel furnace dust, scrap from plating factories, and zinc alloys from the casting industry.
• Consumer Sources: Used batteries and discarded plated materials.

3. Applications and Technologies

Recycled zinc is mainly used in steel galvanization, alloy production, chemicals, and fertilizers.

Common technologies include: Waelz, electric furnaces, hydrometallurgical (chemical) processing, and combined models to enhance efficiency and reduce waste.

4. Relevant Policies and Regulations

Vietnam strictly enforces regulations on:

• Scrap Imports: (Decree No. 08/2022/ND-CP)
• Hazardous Waste: (Circular No. 02/2022/TT-BTNMT)
• Environmental Assessment and Emission Control: (QCVN 19:2009, QCVN 40:2011, etc.)

5. Opportunities and Challenges

• Challenges: Limited technology, high environmental costs, and a lack of stable raw material sources.
• Opportunities: Government policies encouraging recycling, strong market demand, and opportunities to access green capital and technology.

Zinc recycling is not just an economic solution but also an environmental responsibility. VMRF is committed to supporting businesses in building a sustainable, efficient recycling industry that aligns with national development goals.
