Overdue Electronic Product Recycling Plan

1. Scope Definition

Overdue electronic products refer to those that have exceeded the specified usage period or storage period. They mainly include:

· Information technology equipment: servers, computers, printers, network devices

· Communication equipment: mobile phones, telephone exchanges, base station equipment

· Office electronics: copiers, scanners, projectors

· Industrial control equipment: PLCs, industrial control computers, measuring instruments

· Other electronic and electrical products

2. Receipt and Classification Evaluation

2.1 Inventory Registration

· Establish a unique identification code traceability system

· Record product model, inventory time, original use, etc.

· Conduct preliminary appearance inspection and basic condition assessment

2. 2 Classification Criteria

Classify according to product type, material composition, and pollution level:

· Reusable complete units

· Disassemblable and recyclable components

· Fully scrapped and recycled category

· Containing special pollution sources category

3. Data Security Processing

3.1 Storage Medium Handling

· Hard drives, solid-state drives: Use physical destruction and data overwrite for dual protection

· Memory sticks: Perform professional demagnetization treatment

· CDs, tapes: Mechanical crushing treatment

3.2 System Information Erasure

· Perform system-level data erasure for complete units

· Clear network configurations, user settings, etc., of sensitive information

· Operated by professionals and issue a data destruction certificate

4. Disassembly and Sorting Process

4.1 Complete Unit Disassembly

· Develop disassembly processes based on product structure characteristics

· Use specialized tools for orderly disassembly

· Maintain the integrity of different material components

4.2 Component Classification

· Circuit boards: mainboards, expansion cards, control boards, etc.

· Metal components: chassis, brackets, heat sinks, etc.

· Plastic components: shells, panels, structural components

· Special materials: display screens, batteries, photoconductive drums, etc.

5. Material Recycling Technology

5.1 Metal Materials Recycling

· Precious metals: Extract gold, silver, and palladium through wet metallurgical technology

· Non-ferrous metals: Copper, aluminum, tin through smelting and regeneration

· Black metals: After magnetic separation, used as steelmaking raw materials

5.2 Non-metal Materials Treatment

· Plastics: Classified by material, cleaned, and granulated

· Glass: Professional treatment of display device glass

· Rubber: Shredding for resource utilization of seals, etc.

6. Special Component Handling

6.1 Battery Types

· Lithium batteries: Disassembly and recycling in an inert environment

· Lead-acid batteries: Professional collection of lead plates and electrolytes

· Nickel-cadmium batteries: Focus on handling cadmium pollution issues

6.2 Display Devices

· CRT monitors: Separate cone glass and screen glass

· LCD monitors: Recycle liquid crystal and backlight materials

· Touch screens: Separate glass substrate and functional film

6.3 Mercury-Containing Components

· Backlight sources: Process in a negative pressure environment

· Switching devices: Professional collection of mercury elements

7. Environmental Protection Measures

7.1 Site Requirements

· Leak-proof ground and wastewater collection system

· Zone-based operation to avoid cross-contamination

· Special hazardous waste storage area

7.2 Pollution Control

· Dust from crushing: Equipped with bag dust removal devices

· Organic waste gas: Set up activated carbon adsorption system

· Cleaning wastewater: Establish wastewater treatment facilities

8. Quality Management System

8.1 Process Control

· Develop operation instructions for each process

· Establish key quality control points

· Regularly conduct process parameter verification

8.2 Record Tracking

· Establish a complete logistics ledger

· Record the final destination of all materials

· Keep the processing records for at least three years

9. Final Disposal Management

9.1 Hazardous Waste Disposal

· Entrust a licensed hazardous waste disposal company

· Implement the hazardous waste transfer form system

· Regularly review the qualifications of the disposal unit

9.2 Resource Utilization

· Clearly define the usage direction of recycled materials

· Ensure downstream utilization complies with environmental protection requirements

· Track the environmental benefits of recycled materials
