PET is one of the most popular and used plastic packaging materials among fully recyclable plastics.

Waste PET bottle bricks are recycled, cleaned, pelletized, and thermoformed into various shapes. Bottle-to-bottle recycling means more sustainable packaging.

PET bottle recycling is essential for being environmentally responsible, helping reduce emissions, and protecting the planet.

Getting the Best Out of PET Bottle Recycling

PET bottle recovery is a critical time to reduce plastic waste in the environment. A few key moments are provided below:


  • Immediately after using PET bottles, they should be cleaned and placed in the recycling bin. Avoid placing PET bottles in the general trash.
  • PET bottles exposed to sunlight and air for an extended period will accelerate deterioration and affect their recovery quality. Therefore, recovery is recommended to be accelerated to avoid the bottle’s deformation or discoloration.

Step 2:Correct categorization

  • PET bottles belong to the category container category; recycling should be separated from other plastics or garbage classifications and placed in a special PET bottle recycling bin or container.

Step 3:Clean up contaminants.

  • Be sure to pour out and clean any liquid or residue from the bottle before recovery. Residual beverages or residual food scraps may result in reduced recovery quality.

Step 4:Remove caps

  • Caps must be removed when recycling. Caps are often made of different materials and should be recycled separately or disposed of in the general waste stream.

Step 5:Flatten the bottle

  • Squashing PET bottles to start putting them into the recovery bin saves recovery space and improves recovery efficiency.

Step 6:Recovery Stamp

  • Choose to purchase PET products with the “Recovery Stamp” printed, indicating that the product meets the recycling standards and can be reused after recycling.

Step 7:Recycling and cleaning

  • Collected recyclable waste plastic bottles are passed through the pet recycling washing line: conveying-unpacking-removing labels-crushing-thermal washing-friction washing-sedimentation separation-optical sorting, and other steps to produce high-quality food-grade pet bottle flakes.

Step 8:pet plastic pelletizing

  • High-quality pet bottle flakes are converted into crystalline plastic granules through the pelletizer melt to lay the foundation for subsequent plastic reuse.

Step 9:Secondary utilization of pet plastics

  • Manufacturers send these recycled, recyclable PET pellets for use in various industries. Example:
    Chemical fiber grade (textile industry, building materials industry, garment industry, etc.)
    Food grade (pet preforms, plastic packaging, plastic food bags, etc.)


Environmental benefits of PET bottle recycling

PET bottle recycling not only reduces the amount of waste going to landfill, it also brings significant environmental benefits:

Energy savings:

  • Recycling 1 PET bottle saves about 40% of the oil used, equivalent to reducing gasoline consumption by about 0.6 liters.

Reduced carbon emissions:

  • The carbon footprint of PET bottle recovery is equivalent to 20% of the production of new PET bottles, significantly reducing greenhouse gas emissions and contributing to climate change.

Protect the oceans:

  • Default recycled PET bottles can easily flow into the ocean, damaging the marine ecosystem. Recycling PET bottles reduces marine geological pollution and protects marine life and the environment.

Saving Natural Resources:

  • PET bottle recycling reduces oil extraction and minimizes using limited natural resources such as wood and water.

Promote sustainable development:

  • PET bottle recycling is a best practice of resource recycling and reuse, promoting the goal of sustainable development and creating a greener environment for future generations.


The economic benefits of PET bottle recycling

PET bottle recycling not only helps preserve the environment but also provides significant economic benefits:

Reduced Costs

  • Recycling PET bottles reduces manufacturing costs by replacing new PET material from crude oil—reducing landfill costs.

Creates Jobs

  • The recycling industry creates jobs from collection and sorting to reprocessing. Recycling centers, processing plants, and other related businesses thrive.

Promoting Innovation

  • PET bottle recycling promotes the development of new and innovative materials. The reuse of recycled materials creates new goods and industries.

Stimulating the Economy

  • The growth of the recycling industry drives economic activity, creating an economic chain from collection to reprocessing.PET bottle recycling supports sustainable industries and enhances overall economic competitiveness.

Saving Energy

  • Recently, PET bottles have been recovering significantly less energy in producing new PET. Recovery destroys dependence on limited natural resources and contributes to energy security.

What types of PET bottles can be recycled?

  • Most PET bottles, including beverage bottles, cooking oil bottles, and personal care products, can be recycled.

Do I need to wash PET bottles before recycling them?

  • No cleaning is required, but please make sure to pour out the remaining liquid in the bottle or finish repairing it.

What happens to PET bottles after recycling?

  • PET bottles can be melted down into recycled PET materials used to manufacture new products such as apparel fibers, automotive zero, and food component packaging.
