PETsorteringsströmmar

PETsorteringsströmmar refers to the different streams or categories into which polyethylene terephthalate (PET) plastic is sorted during the recycling process. PET is a widely used plastic, particularly for beverage bottles, and effective sorting is crucial for successful recycling.

The primary goal of PET sorteringsströmmar is to separate PET from other types of plastic and materials, and then further categorize it based on specific characteristics. This typically begins with a manual or automated sorting process that removes contaminants like caps, labels, and other plastic resins.

Once sorted for PET content, further streams are often created based on color. Clear PET bottles are highly valued and usually form a distinct stream. Colored PET, such as green or brown bottles, are also separated, as they can affect the quality and appearance of recycled PET. Sometimes, even shades of color are further refined.

Advanced sorting technologies, such as near-infrared spectroscopy, can identify and separate different types of polymers, ensuring that only PET enters the recycling loop. This meticulous sorting is essential to produce high-quality recycled PET (rPET) that can be used to manufacture new products, including food-grade packaging. The efficiency of these PETsorteringsströmmar directly impacts the economic viability and environmental benefits of PET recycling.
