The Lindner Washtech PET Recycling System Solution is a fully engineered and modular process line developed for the high-quality recycling of PET bottles and rigid PET packaging. It integrates delabelling, size reduction, washing, separation, and drying technologies into a coordinated system designed to produce high-purity PET flakes suitable for demanding applications such as sheet production, fiber, and bottle-to-bottle recycling.
PET recycling requires strict control over labels, adhesives, foreign polymers, and organic contamination. The Washtech system addresses these factors through a precisely balanced combination of mechanical, thermal, and separation processes.
Post-Consumer PET Bottles
This category includes PET bottles from household and municipal collection systems, typically used for beverages, water, and food packaging. These streams are highly variable and often contain:
Typical challenge: complex contamination mix and strict purity requirements for high-end applications.
System objective: efficient delabelling, glue removal via hot washing, and precise density separation to eliminate foreign polymers.
Result: high-quality PET flakes with low PVC and polyolefin content, suitable for food-grade and bottle-to-bottle processes.
Post-Commercial PET Packaging
This stream comes from commercial and industrial sources, such as PET trays, containers, and packaging used in logistics and retail. Compared to post-consumer material, contamination levels are often more predictable, but still include:
Typical challenge: removal of labels and incompatible polymers while preserving flake quality.
System objective: controlled size reduction and intensive washing to achieve consistent flake purity for extrusion and thermoforming applications.
Result: clean PET flakes suitable for sheet production and rigid packaging recycling.
PET with Special Contaminants (Labels & Adhesives Focus)
Some PET streams contain high levels of glue, sleeve labels, or difficult-to-remove surface residues, which can strongly impact washing efficiency and flake quality.
Typical challenge: adhesive removal without excessive energy or chemical use.
System objective: integration of Hot-Wash technology and optimized friction washing to break down glues and surface contamination.
Result: improved flake cleanliness, reduced stickiness, and better downstream processing stability.
Why the PET Recycling System Solution is Strategic
PET recycling demands extremely high process control. The Washtech solution is not a standalone machine setup but a fully integrated system, where each stage — from delabelling to final drying — is calibrated to protect flake integrity while maximizing contaminant removal.
Main Operational Benefits
In Summary — PET Recycling System Solution
The Lindner Washtech PET Recycling System Solution provides a tailor-made approach for post-consumer and post-commercial PET streams, including heavily labelled or adhesive-contaminated material. Through integrated delabelling, washing, separation, and drying technologies, it enables the production of high-value PET recyclate aligned with circular economy and high-performance application standards.
