PETkierrätyksessä

PETkierrätyksessä refers to the recycling of PET plastic. PET, or polyethylene terephthalate, is a common type of plastic used for beverage bottles, food packaging, and synthetic fibers. Recycling PET is crucial for environmental sustainability as it reduces the amount of plastic waste ending up in landfills and oceans, conserves natural resources, and lowers energy consumption compared to producing new plastic from raw materials.

The PET recycling process typically begins with collection, often through deposit-refund schemes or separate waste collection systems. Once collected, PET bottles are sorted by color and type to ensure high-quality recycled material. They are then cleaned to remove any contaminants like labels, caps, and residues. The cleaned plastic is then shredded into small flakes. These flakes are further processed, often through washing and melting, to produce recycled PET pellets.

These recycled PET pellets can then be used to manufacture a wide range of new products. This includes new plastic bottles (though often not for direct food contact unless specific processes are followed), clothing fibers (polyester), carpets, strapping, and even components for the automotive industry. The effectiveness of PETkierrätyksessä depends on efficient collection infrastructure, advanced sorting and processing technologies, and consumer participation in recycling programs. Legislation and public awareness campaigns also play significant roles in promoting and improving PET recycling rates globally.
