All scraps that constitute waste are collected. It is taken to a recycling plant for further inspecting and screening. According to the Department of Environment and Natural Resources (2021), the annual waste produced by a population of 100 million Filipinos is 21 million metric tons.

Once PET is collected, it will be compressed to ensure ease of transport. Due to its lightweight property, the efficiency of transport is assured. Furthermore, this course of action reduces greenhouse gas emissions from transportation (Petcore, n.d.)

As the PET is in the form of small crushed flakes, it is thoroughly washed to remove the ground-up lids, rings, labels, and residual glue. Moreover, it is processed by a high-temperature decontamination section to remove the post-consumer substances and flavors.

As the accumulated waste is transported to the recycling plant, the separation of recyclable materials such as plastics, glass, and metals is conducted. They move at their respective recycling streams. A high-value recyclable polymer such as PET is segregated manually or by using an automatic system. Being meticulous is essential in determining the presence of other plastics because contamination of the PET recycling process is possible, which will limit the quality for reduction, efficiency is detrimentally affected, and it would be not valuable enough (Petcore, n.d.).

Bales of compressed PET are directed to the processing center in which the waste PET is converted into recycled PET (rPET). It is further separated with respect to their color streams and a plastic bottle shredder is used to create small crushed flakes.

After decontamination, it is melted into spherical like crystalline PET pellets which will be suitable for creating new materials such as PET bottles, fibers, etc.
