PET-Polyethylene terephthalate Recycling
Recycling Used PET Flakes To Resin

Volatile prices for PTA and EG as well as widespread PET collection and sorting systems make PET recycling a very attractive option. Furthermore, consumer attention is becoming increasingly focused on “green” products, which is making PET products with recycled content increasingly popular

PROCESS FLOW CHART
FEATURES
RECONDITIONED PET PROCESS:

Polyethylene terephthalate (PET) recycling is a critical process aimed at reducing waste and conserving resources. PET is commonly used for packaging, particularly for beverage bottles. Here's an overview of the PET recycling process:

1. Collection

- Curbside Collection: PET bottles are collected through municipal recycling programs.

- Drop-off Centers: Consumers can also drop off PET bottles at designated collection points.

2. Sorting and Cleaning

- Sorting: The collected PET bottles are sorted from other materials, typically using automated processes such as optical sorting.

- Cleaning: The sorted PET bottles are washed to remove any remaining labels, caps, and contaminants.

3. Shredding and Pelletizing

- Shredding: The cleaned PET bottles are shredded into flakes.

- Pelletizing: The flakes are melted and formed into small pellets called "nurdles."

4. Further Purification

- Decontamination: The pellets may undergo further purification processes to remove impurities and contaminants.

  - Washing: Washing with hot water and detergents.

  - Vacuum Treatment: Using vacuum treatment to remove volatiles.

  - Solid-State Polycondensation (SSP): A process where the pellets are heated under vacuum to remove impurities and increase the molecular weight of the PET.

5. Reprocessing

- Reprocessing: The purified PET pellets can be reprocessed into new products.

  - Injection Molding: Used to make new bottles, containers, and other items.

  - Extrusion: Used to produce fibers for textiles or sheets for thermoforming applications.

6. End Products

- New PET Bottles: Recycled PET can be used to make new bottles.

- Fibers and Textiles: Used in clothing, carpets, and other textile products.

- Packaging Materials: Used for food and non-food packaging.

- Engineering Plastics: Used in automotive parts, electrical components, and more.

Environmental Benefits

- Energy Savings: Recycling PET uses less energy compared to producing virgin PET.

- Resource Conservation: Reduces the need for raw materials.

- Waste Reduction: Helps divert waste from landfills and reduces litter.

Challenges

- Contamination: Contaminants like labels, adhesives, and other plastics can affect the quality of recycled PET.

- Color Sorting: Clear PET bottles are preferred for recycling, but colored bottles can be more difficult to process.

- Economic Viability: The cost of recycling versus the market value of recycled PET can influence the viability of recycling operations.

Technological Advancements

- Advanced Sorting Technologies: Improved sensors and imaging technologies for more efficient sorting.

- Chemical Recycling: Processes that break down PET into its monomers, which can then be repolymerized into new PET.

Conclusion

PET recycling is a crucial part of managing plastic waste and reducing environmental impact. Continuous improvements in technology and infrastructure are needed to make the process more efficient and sustainable.
