The plastics recycling sequence
- Plastics are collected and sorted into different types of plastics.
- The plastic articles are reduced in size i.e. cut up into smaller pieces with a granulator or shredder.
- The granulated flakes are put through a wash plant to remove labels, residual contents, and soil.
- After drying the granules are fed into an extruder. They are melted and the met is extruded through a multi-hole die in the form of continuous strings.
- The strings are water cooled and chopped into pellets by a revolving cutter.
- The pellets are bagged and ready to be sold to a converter who uses the recyclate or recycled materials to produce new plastics products.
