Quality and productivity with Piovan's solutions for post-consumer plastic 

Recyling of post-consumer plastics includes various processes involving dedicated equipment from the Piovan recycling products range.

Also, converting of recycled plastic is very different from that of virgin material and therefore requires particular equipment as well.

Post-consumer recycled (PCR) converters in raw materials need solutions that ensure high and consistent production standards.

Producers, using PCR plastic must be able to adapt their plants to allow them to handle a material that is neither standard nor constant in terms of batch quality, as it may come from different sources. As a result, the chemical and physical characteristics may vary greatly as well as the presence of low boiling volatiles (VOC) and other contaminants (NIAS).

Improper use of post-consumer material, such as rPET or flakes, could cause:

  • reduction in the useful life of the equipment
  • process instability
  • presence of potential contaminants in the final product.

The PiovanGroup offers unique solutions for the treatment and production of recycled plastics (PET, PP, HDPE - but not only these), in different forms such as granules or flakes, which guarantee production quality and maximum equipment utilisation.

The offer includes conveying systems, shredders and grinders for the size reduction of the material to be recycled, crystallisers to crystallise materials in the amorphous state and dehumidifiers and hot-air dryers. The PiovanGroup also produces deodorisation systems, solutions for the condensation of low-boiling contaminants and analysis instruments to detect the presence of contaminants in real time. Finally, it develops software to support the quality control system by tracking of production processes and products parameters, storing data for years and interfacing with the company ERP.

The use of Piovan machineries, specific to the treatment of recycled plastic, contributes to an increase in the quality of the final product and at the same time, controls scrap, energy consumption and costs.
