Find out more about the multi-stage technological process of regranulate production.
Conversion of waste polyethylene film into finished Contalen pellets takes a multi-stage process. This process is not only grinding, feeding into the extrusion system, plasticizing and granulation.
It also includes the stage of the removing of solid and fibrous contaminants, such as metal and wood chips, paper or textile fibres, or chemicals such as ink. Lines designed for a specific application are based on the following sequences of subprocesses and equipment.
Waste arrives in compressed bales
Shredded plastic is cleaned in a washing system
Finished regranulate is dried
Waste from bales is sorted
Washed film flakes undergo homogenisation, degassing and are filtered
Finished regranulate is mixed and averaged
“We cannot eliminate the plastics, it is a too valuable material. RECYKLING is the shortest path to achieve sustainable development.”
