The method used in the recycling of plastic packaging is this.First the plastic packaging collected in containers is put through a rough elimination process in the collection/separation facilities.Here, the plastic packaging separated based on type is shredded into smaller volumes and washed and dried to store.
After the broken pieces are separated according to density (PET, PE, PVC..etc) a second wash is done using chemicals. After the drying and metal control procedures following the wash the pieces go through a drying process and go to the extruder.
The extruder is an equipment which allows for the broken cleansed plastic pieces to be melted into granules.
The plastic packaging coming out of the extruder therefore become granulated. These granules maybe be used in production as primary raw material.
