Recycling

The recycling of plastics is evolving from simple reprocessing to material upgrading, where contaminated, heterogeneous and degraded polymer streams must be transformed into usable, high-quality compounds.

Modern recycling processes face critical challenges:

• presence of VOC, moisture and residual monomers

• contamination from inks, adhesives, fillers and additives

• wide variability in feedstock composition

• degradation of mechanical and rheological properties

Conventional extrusion systems often fail to ensure sufficient purification, devolatilization and homogenization of recycled polymers.

ICMA solution

ICMA designs advanced recycling extrusion lines based on co-rotating twin-screw technology, specifically engineered to process post-industrial and post-consumer plastic waste.

Thanks to the intrinsic characteristics of twin-screw extrusion, ICMA systems allow:

• intensive and controlled melt mixing

• efficient degassing and devolatilization

• removal of volatile contaminants and odors

• stable processing of highly variable input materials

The modular configuration of screws and barrels enables the integration of:

• multiple degassing ports

• atmospheric and vacuum devolatilization zones

• optional stripping sections

• advanced feeding solutions for flakes, powders and regrinds

Typical applications

• Polyolefin recycling (PE, PP)

• PET and engineering plastics recycling

• Film and packaging waste

• Industrial scrap upgrading

• Odor reduction and purification of recycled compounds

Why ICMA

ICMA does not simply supply extruders:
we engineer recycling processes.

Each recycling line is developed starting from:

• material characterization

• contamination level

• target output quality

The result is a tailor-made recycling solution capable of upgrading recycled plastics to meet demanding industrial specifications.
