Starlinger recycling technology

Starlinger recycling technology is a division of Austrian-based Starlinger & Co GmbH and has been producing plastics recycling machines since 1987. We provide solutions for inhouse production scrap and post-consumer plastics. Typical input streams are PET bottles, HDPE bottles, LD and LLDPE film, polyester, PA or PP fibres and filaments as well as non-wovens, PP raffia bags, PP, HDPE or PET tapes, and injection moulding articles.

We are specialized in PET bottle-to-bottle recycling, recycling of post-consumer polyolefins including odour reduction, recycling of polyester fibres and non-wovens, and recycling of PP raffia.

Typical recycling solutions:

  • PET bottle-to-bottle recycling lines (FDA, EFSA, brand owner approved)
  • HDPE bottle-to-bottle and cap-to-cap recycling lines (FDA approved)
  • Post-consumer polyolefin and PS recycling lines
  • Odour reduction technology
  • PET flake-to-fibre/filament, polyester fibre/filament recycling lines
  • Recycling lines for woven PP raffia materials, including recoBATCH compounding lines
  • Post-consumer big bag-to-big bag recycling
  • Film recycling lines (blown-, cast-, biaxially oriented film)
  • EPS, EPP, EPE recycling lines
  • WEEE recycling lines
  • Melt filters including screen changers with power-backflush for polyolefins, PET and polyester
  • Candle/sleeve filters for polyester melt filtration

PET and polyester applications

Most important for PET and polyester recycling applications is the hazzle-free reuse of the repelletised material without negatively influencing the extrusion or injection moulding process and without compromising the quality of the end product.

The Starlinger recoSTAR product line offers the ideal solutions for PET and polyester recycling as the lines are equipped with optimal pre-drying of the PET flakes, special screw design for gentle processing of the melt, inline quality control, and optional downstream Solid State Polycondensation. 

The recoSTAR PET series is designed for recycling of post-consumer PET bottle flakes after the washing process, as well as for in-house recycling of PET flakes from bottles, preforms, strapping bands and sheets. The end product is always melt-filtered, uniform granulate that can be used for a wide range of applications.

recoSTAR PET FG and FG+

PET flakes are heated and dried in a two-stage process, first with hot air, then by means of dry air or vacuum. The special design of the dryer outlets results in centre flow prevention, consistent residence time and FIFO processing. This ensures decontamination for food contact applications and ideal preparation for the extrusion process with IV increase. A choice of filtration and pelletising systems is available. Once installed, the unit can be equipped with an SSP reactor (iV+) to increase viscosity and decontamination levels.

recoSTAR FG and FG+ are cost-effective PET food-contact recycling systems with a compact footprint, minimal energy consumption and moderate IV increase.

The end product is melt filtrated, uniform granulate that can be used for a wide range of food-contact applications.

PET strapping

PET flakes are also a valuable secondary resource for strapping bands, which can be made from up to 100 % recycled PET (rPET) when processed with the Starlinger iV+ technology.

PET has an important economic advantage: it can be “upcycled”. The quality of the recycled PET is often higher than before the recycling process. In order for rPET to achieve the high intrinsic viscosity (IV) required for strapping bands it undergoes a solid state polycondensation (SSP) process.
