O poliéster reciclado (também conhecido como rPET) é produzido principalmente a partir de garrafas plásticas PET pós-consumo, como as de água e refrigerante. Essas garrafas são coletadas, lavadas e trituradas em pequenos flocos. Os flocos passam por um processo de fundição e extrusão, que os transforma em fibras que podem ser usadas para fabricar tecidos. Também é possível que outros resíduos plásticos e roupas de poliéster descartadas sejam usados para gerar o poliéster reciclado, embora em menor escala.

Esse processo é uma alternativa mais sustentável ao poliéster virgem, já que reduz a dependência de recursos não renováveis (como o petróleo, que é base do poliéster tradicional), diminui o desperdício de plástico e gera menos emissões de carbono no processo de produção.

How are recycled PET bottles converted into polyester fibre?

Recycled PET bottles are converted into polyester fibre through the Regenerated PSF manufacturing process. First, used PET bottles are collected and sorted to remove contaminants. Then they are washed and shredded into small pieces called PET flakes. These flakes are melted and filtered before being extruded through a spinneret to form polyester filaments. The filaments are cooled, stretched, crimped, and cut into staple fibres. This fibre is known as Recycled Polyester Staple Fibre (RPSF) and is widely used in textile manufacturing, home furnishing products, automotive interiors, and nonwoven fabrics.
