Te ważne of Polymer Sorting in Recykling

Effective polymer sorting is foundation of a succecful recykling system. Different plastics have varying chemicatures, melting points, and additivee, which sich they mutt bee processed separately to produce high-quality recitates.

Tradycja Sorting Methods andTheir Limitations

Conventional methods have been the backbone of plastic recykling for decades, but each comes with inherent drawback that limit through put andd critivacy in modern high-volume facilities.

Manual Sorting

Manual sorting relies on workers picking plastics from exployar belts. While humans can identify itemy based on shape, colar, ande labels, the process is slow (typically 5- 10 items per minute per person), labour-intensive, andd subject to consider to facigue.

Separation density

Density- based methods such as sink- float tanks exploit thee different densities of polimers (np., PET sinks at 1.38 g / cm ³ while HDPE floats at 0.96 g / cm ³). This technique works well for separating polyolefins frem heavier plastics, but it struggles with materials of simisilar density, such as PP (0.90 g / cm ³) and HDPE, or witch multi- layer pacging that contains both hevy anlight materials.
