PET plastic bottles can be physically recycled in a relatively straightforward way by drying and granulating the cleaned and discarded bottles.

A process for depolymerizing used PET plastic bottles under specific reaction conditions to produce beneficial compounds, such as low-grade fuel gasoline.

Recycling materials need a lot of energy and are frequently more expensive than polymers that are brand new

Waste PET plastic bottles should be cut into pieces, HDPE, aluminum, paper, and adhesive should be separated from PET, and then the PET should be washed, dried, and pelletized

Low cost, new polymers, and low energy consumption for recycling.

Microplastics may also be created during this process.

This microplastic contamination has been caused by problematic recycling of these PET polymer particles.

However, because the procedure is so straightforward, recycled raw materials are mostly used to make products that do not directly come in contact with people.
