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.
