Environmental Recycling Processing Procedure

In the import and export trade and industrial operations of Hong Kong, the standardized handling of returned goods is a crucial link in maintaining the ecological environment and implementing the concept of circular economy. Returned goods include various types of goods that are returned to Hong Kong due to reasons such as non-compliance with quality standards, order cancellations, or expiration of shelf life, including electronic components, packaging materials, industrial consumables, etc. Their compositions are complex, and improper disposal can lead to resource waste and environmental pollution. The following is a standardized and environmentally friendly process for the recycling and processing of returned goods in Hong Kong, ensuring that each step complies with Hong Kong's environmental protection regulations and industry norms.

1. Reception and Classification of Returned Goods

1.1 Qualification Verification and Quantity Counting: The recycling and disposal institution must have a waste disposal license issued by the Hong Kong Environmental Protection Department. Before receiving returned goods, verify the customs declaration, return certificate, composition manual, etc. of the goods, confirm the source, category, and hazardous substance content. Also, conduct quantity counting and appearance inspection, and record abnormal situations such as damage and leakage.

1.2 Precise Classification and Ledger Establishment: Divide returned goods into three categories: recyclable, harmless disposal, and hazardous waste. The recyclable category includes electronic components, metal parts, plastic packaging, etc.; the harmless disposal category includes ordinary waste without harmful substances; the hazardous waste category includes electronic components with mercury and lead, waste chemical raw materials, etc. Establish an exclusive ledger for each batch of goods, recording the category, quantity, classification result, disposal destination, etc., to achieve full-process traceability.

2. Environmental Pre-treatment Phase

2.1 Pre-treatment of Hazardous Waste: For returned goods with oil and solvents, perform solid-liquid separation and use professional equipment to recover the waste liquid; for electronic components with heavy metals, conduct sealed disassembly to prevent the leakage of harmful substances; for materials prone to volatilization and oxidation, place them in dedicated sealed containers and equip with air pollution adsorption devices to prevent air pollution.

2.2 Sorting and Purification of Recyclable Materials: For electronic returned goods, through manual sorting combined with automated equipment, separate circuit boards, metal contacts, plastic casings, etc.; for packaging materials, remove stains and impurities, classify them by material into polyethylene, polypropylene, etc., to prepare for subsequent recycling. The wastewater generated during the pre-treatment process needs to pass through a sewage treatment system to meet the standards before being discharged, and dust is collected and treated by dust collection equipment.

3. Environmental Processing and Resource Recycling through Multiple Channels

3.1 Resource Utilization of Recyclable Materials

◦ Electronic Materials: Send the sorted circuit boards to professional dismantling enterprises, use low-temperature dismantling and wet metallurgical technology to extract gold, silver, copper, etc. from the circuit boards; plastic casings are crushed, cleaned, and granulated, and used to produce industrial components and packaging materials; metal components are melted and purified, and re-enter the manufacturing process.

◦ Packaging and Consumable Materials: Paper packaging is deinked and pulped to regenerate pulp; wooden packaging is disinfected and ground, processed into raw materials for wood boards or biomass fuel; textile consumables are classified and used for the production of recycled textiles or heat energy recovery.

◦ Hazardous Waste Compliance Disposal: Returned goods that belong to the "Hong Kong Hazardous Waste List" need to be entrusted to qualified hazardous waste disposal institutions. According to their characteristics, they are treated using methods such as solidification stabilization, high-temperature incineration, or safe landfill. The disposal process strictly follows the requirements of the "Waste Disposal Regulations" to ensure zero leakage of harmful substances.

◦ Treatment of Harmless Disposal Materials: Materials without recycling value and harmless returned goods are sent to designated waste disposal centers. They are disposed of through incineration for power generation or sanitary landfill. The heat energy generated by incineration can be converted into electricity and fed into the power grid for secondary utilization.

4. End-of-Line Supervision and Process Closure

1. Data reporting and verification: The disposal institutions regularly submit the classified data of returned port materials, processing records, and emission monitoring reports to the Hong Kong Environmental Protection Department for verification and sampling inspection, ensuring that the processing procedures comply with environmental protection standards.

2. Tracking of disposal product flow: For recycled products such as metal particles and plastic particles, record their sales destinations and uses; for residual residues from hazardous waste disposal, track the final landfill or treatment location, forming a complete closed loop of "receiving - classification - processing - product tracking".

3. Issuance of disposal vouchers: After the processing is completed, provide the recipient of the returned materials with a formal disposal voucher, including information such as the processing method and proof of environmental compliance, as a basis for the enterprise's compliant operation.

V. Requirements for Process Implementation

1. Qualification guarantee: Enterprises involved in the recycling and processing of returned port materials must obtain the corresponding waste treatment qualifications. Unqualified units are strictly prohibited from participating in the process.

2. Technical guarantee: Equip with advanced sorting, dismantling, and pollution control equipment, adopt low-energy consumption and low-emission treatment technologies to reduce the environmental impact of the process.

3. Personnel guarantee: Conduct professional training for operators to familiarize them with the processing norms and safety protection knowledge of various materials, avoiding environmental risks caused by improper operation.

The environmental recycling and processing of returned port materials is an important part of Hong Kong's construction of a green supply chain. Through the implementation of standardized processes, it can not only reduce the harm of waste to the environment, but also maximize the recycling value of materials, promoting the coordinated development of Hong Kong's import and export trade and environmental protection undertakings.
