1. Recyclability
Material type: Common plastic boxes such as PS, PP, PE, and PET are theoretically recyclable, but they need to be sorted and processed.
Degree of pollution: Plastic boxes contaminated by food or oil need to be cleaned before recycling, otherwise the recycling quality may be affected.
2. Recycling process
Classification collection: Classification collection by material type, usually through community recycling points or special recycling bins.
Cleaning treatment: After recycling, it needs to be cleaned to remove residues. Severely contaminated ones may be rejected or used for low-value products.
Crushing and granulation: The cleaned plastic boxes are broken into small pieces, then melted and granulated as recycled raw materials.
Reproduction: Recycled granules are used to make new plastic products, such as packaging materials, building templates, etc.
3. Recycling challenges
Difficulty in classification: Different types of plastics need to be recycled separately, and mixed recycling will affect the quality of recycling.
Pollution problem: Food residues and oil pollution increase the difficulty and cost of cleaning.
Economical: The recycling cost is high, especially for small-scale recycling companies, which may lack economic motivation.
4. Environmentally friendly alternatives
Degradable materials: Biodegradable materials such as PLA and PHA can reduce environmental burden.
Reuse: Use reusable containers to reduce the use of disposable plastic boxes.
Summary
Disposable plastic boxes can be recycled, but face challenges such as classification, pollution and economy. To reduce environmental impact, it is recommended to use degradable materials or reusable containers.
