While Polyethylene Terephthalate (PET) recycling has made significant progress, several challenges hinder its widespread adoption in a circular economy. Contamination from other plastic types, such as polyvinyl chloride (PVC), and non-PET materials poses a major issue, affecting the quality and usability of recycled Polyethylene Terephthalate (PET). Developing effective sorting and separation techniques, along with educating consumers on proper disposal practices, are crucial to mitigate this challenge. Additionally, increasing the collection infrastructure, particularly in regions with limited recycling facilities, is vital to ensure a steady supply of PET waste for recycling.

Despite the challenges, there are several opportunities for the Polyethylene Terephthalate (PET) industry to embrace a circular economy. Collaboration among stakeholders, including manufacturers, recyclers, policymakers, and consumers, is essential to establish a robust recycling ecosystem. Encouraging the use of recycled Polyethylene Terephthalate (PET) in various applications, such as textiles and packaging, can create a market demand for rPET and drive the development of recycling infrastructure. Furthermore, promoting product design that facilitates easier recycling and the use of recycled content can contribute to a more sustainable PET value chain.
