Recycling Plant for PET Waste.
From Waste to Value.


Recycling Plant for Plastic Waste. Upgrading  to Valuable New Material.

As a manufacturer of food and beverages, pharmaceuticals and packaging your quality strategy is a no compromise standard: production processes must excel in hygienic standards, run cost-efficiently and safely.

This benchmark project opens up new perspectives on premium materials that will shape our future. Even and especially using recycled material.

The Highlights

  • End product: food standard multilayer and stripe foil from 100% recycling material
  • Upgrading PET recycling material with unstable input quality to 100% food standard conformity
  • Production of granulate and foils in the same line
  • Compact design, reduced space footprint, cost reduction
  • Independence from third party suppliers: autonomous, stand-alone solution
  • Inline quality control fulfills premium customer specifications in the end product (IV-value > 0,8)
  • Superior cleaning capabilities

Benchmark Benefits

Move ahead to your next performance level with our extrusion technology and expertise. The Leistritz MaXX extruder series is your answer to delivering the performance you need, when you need it. Scaled and optimised for the formulation at hand. Flexibly, easily. You can count on the inspiration and process expertise of our engineers.

High specific torque (up to 15,0 Nm/cm³) delivers high output at reduced energy consumption in the ZSE MAXX twin screw extruder

Better conservation of PET's material properties, less hydrolitic degradation.

Premium quality homogenisation of the melt at low energy levels.

Gentle material handling.

Rapid melting of the polymer prevents degradation of the polymer matrix.

Higher colume in the screw empowers better degassing / devolatilisation performance, even with identical process parameters such as torque and throughput.

Optimised for 100% food standard. Consistently high quality level in the end product thanks to controllable, stable IV parameters. No clouding. high clarity and purity in the foil output.

Tried and tested process reliability and significantly reduced energy consumption leads to better cost-effectiveness und productivity.
