Production of recycled PET

Recycling PET (polyethylene terephthalate) is an important way to reduce plastic waste and reduce environmental impact.

In this article we will take a closer look at the production and sustainability of recycled PET.

Recycled PET is made through a process called mechanical recycling..

  • First, the PET bottles are collected and sorted.
  • Then they are crushed and processed into small pieces.
  • These pieces are then cleaned and stripped of labels and lids.
  • Finally, they are processed into granules that can be used as raw material for new PET bottles.
There is another process to produce recycled PET called chemical recycling. Here, PET is broken down into its components by various chemical processes and then processed back into new PET bottles. Chemical recycling is still relatively new and more expensive than mechanical recycling

Sustainability of recycled PET

Recycled PET has many advantages over virgin PET.

  1. it reduces the need for new raw material made from petroleum.
  2. it saves energy and water in production as recycling uses less energy and water than producing new PET.
  3. it reduces the amount of plastic waste that ends up in landfills or in the environment.

Recycled PET is also better for the environment than other plastics such as PVC (polyvinyl chloride) and polystyrene because it is easier to recycle and contains fewer harmful chemicals. In addition, recycled PET is also reusable in many applications such as packaging, textiles and construction.

However, there are also some disadvantages of chemically recycled PET. First, recycled PET cannot always be produced to the same quality as virgin PET due to the stress of the recycling process and exposure to various chemicals and contaminants. Second, due to the limited availability of PET bottles and the limited capacity of recycling plants, recycled PET cannot always be produced in sufficient quantities to meet demand.


Recycled PET is an important way to reduce plastic waste and reduce environmental impact.
Although there are some disadvantages, the advantages of recycled PET outweigh the disadvantages. It is important that we continue to collect and recycle PET bottles to reduce the production of virgin PET and protect our environment.
