The plastics recycling industry is one of the key pillars of a circular economy. It is what makes it possible to reuse raw materials, reduce oil consumption and reduce CO\u2082 emissions. However, behind this green mission lies a major challenge – the dust problem.<\/x>Processes such as shredding, screening, pneumatic conveying, mixing, drying or sorting of plastics produce significant amounts of fine polymer dust particles. While often invisible to the naked eye, they can have a huge impact on the quality of recyclate, the health of workers and the safety of the plant.\r
Below we discuss five of the most common dust problems in recycling plants – and effective solutions to help prevent them. <\/p>\n <\/div>\n

\n 1. Dust contamination of the material\n <\/p>\n

Dust floating in the production hall can settle on processed plastics, causing secondary contamination. As a result:\r
– <\/span> optical sensors have trouble correctly identifying the material,\r
–<\/span> regranulate loses quality (e.g., tarnishing appears, color change, reduction of mechanical properties),\r
–<\/span> for “clean” applications – such as food packaging or medical components – the material may be disqualified. \r
\r
In the long run, contamination translates into lower efficiency in the recycling process and higher production losses.\r
\r
Solution<\/span>\r
The use of zoned dust collection at screens, separators and conveyor belts helps reduce airborne dust.\r
The best results are obtained by:\r
–<\/span> use of cartridge filters with >99.9% efficiency for particles below 1 \u00b5m,\r
–<\/span> regular replacement and cleaning of filters,\r
–<\/span> separated clean zones for sensitive process stages (e.g. granulation).<\/p>\n <\/div>\n <\/div>\n\n
