Plastic recycling and regeneration by twin screw extrusion: a sustainable solution
Twin screw extrusion technology presents many advantages for the valorization of plastic wastes by recycling or regeneration.
The politics of plastic waste valorisation by recycling and regeneration started in the 1990s is a growing market involved in the sustainable development process.
Clextral has acquired extensive experience in supplying producers with twin screw extrusion solutions for the recycling and regeneration of plastics.
The processed materials can then be revalorised in the production of automotive parts, hollow ware, films, etc.
Twin screw extrusion lines for plastic recycling
The use of twin screw extrusion for technical recycling is accomplished by :
- adding fillers, fibres, pigments, etc.
- devolatilisation (regeneration)
- alloys
- chemical recycling
A few examples of processed products : PP from car batteries (talc supplement, CaCO3), PET bottles, nylon fibres (fibre glass supplement), PET chemical recycling, PE films, crushed PS and PP automotive parts
Advantages of Clextral twin screw extrusion for the recycling and regeneration of plastics :
• Feeding of low density products
• Degassing : accepts high humidity levels
• Adding of fillers, fibres, pigments, etc. (added values)
• Less thermal degradation, controlled self-heating
• Modularity
