PET waste bottles are dirty and must undergo rigorous cleaning to remove oil, dust and other debris before pelletizing. In addition, waste PET bottles usually come with accessories such as caps, labels and bottom holders, which are not compatible with PET because they are usually made of PP/PE and other materials. Therefore, these accessories must be sorted separately during the recycling and pelletizing process of used PET bottles.

LSP (Liquid Polycondensation) improves the quality of recycled PET materials (fibers, flakes, films, low IV polymers), produces high-grade PET fibers, PET packaging tape, PET pellets, PET films, recycled bottle-to-bottle and fiber-to-fiber, and improves the recycling rate and quality of resources.
