PET bottle recycling process begins with collection and de-baling, AI sorting, and dry separation, followed by pre-washing, manual sorting, and metal detection. Bottles are then wet crushed, with sink-float and eddy current separation removing contaminants. Hot washing, friction scrubbing, drying, and optical sorting ensure high-purity flakes, which are bagged for dispatch. In extrusion, rPET flakes are dried, melted, pelletised, and crystallised for better thermal stability and processability.
