Recycling PVC : The cycle

Over 260 000 tonnes of unregulated post-consumer PVC waste were recycled in Europe in 2010. Here is the recycling cycle of a type of plastic that is found mainly in wastewater pipes and communication cable coatings, but also in your windows and outdoor furniture, among other things.

Step 1: Collecting the PVC

PVC trimmings are collected at factories by Paprec Plastiques, using its usual equipment: trucks, skips, cages…

Step 2: Storing the PVC

The materials are stored in the Paprec factories to await treatment.

Step 3: Grinding

The material goes through a grinder which reduces the plastic to granules.

Step 4: De-pollution

As they pass through an overband separator, ferrous matter is removed from the granules.

Step 5: Optical Sorting

The plastics are automatically sorted by type and colour in an optical-sorting station.

Step 6: Granule Purification

The granules are purified and are now ready for micronization or extrusion.

Steps 7 and 8: Extrusion or Micronization

The granules are then extruded (definition of extrusion) or are turned to a fine dust by micronization.

Step 9: The End Products

Three products leave the Paprec factories: pellets, extruded granules, and micronized powder.
The plastic recycling cycle is a step-by-step process. Discover the different steps :
