PET bottles are fully recyclable, which makes them highly sustainable products. Recycling a PET container leads to the reuse and recapturing of PET-roleum feedstocks. When the material is recycled, its polymer chain turns shorter but recycling it twice or thrice may affect its recyclable quality. Hence, it can be concluded that PET bottles can be recycled at least 2-3 times, making them highly sustainable for the environment.
