RecoStar technology: Difference between revisions

Line 43:

* SSP units have a small footprint, convenient height and can be quickly installed on standard industrial floors.

* The optional SSP treatment allows increase of viscosity and consequently higher rPET content in the final product; also suitable for recoSTAR basic and recoSTAR universal recycling lines.

=== PET film and PES fibre recycling ===

The recoSTAR basic recycling line is designed for the in-house recycling of production scrap inline and offline and the perfect choice for hygroscopic and wet materials, e. g. washed post-consumer waste.

PET film and PES fibres can be recycled directly at the production line in an inline process and fed back in repelletised form to the production line. (Brochure)

The recoSTAR universal recycling line allows processing of PET film, PES fibres and nonwovens without pre-cutting; only proportioning to fit conveyor belt dimensions is required. The material preparation in combination with the sophisticated software and the dosing screw allows processing of materials with different bulk densities and even of flakes without changing process parameters. (Brochure)

For both lines high process reliability is ensured through sophisticated line control, for example one button start/stop as well as standby mode for in-line application. Constant high pellet quality and advantageous investment costs are ensured.

PET sheet recycling and sheet inline production (viscoSHEET)

PET sheet flakes can either be recycled to pellets (recoSTAR PET FG, recoSTAR PET iV+) or processed directly inline on a sheet line (viscoSHEET) that produces PET sheet with up to 100 % recycled content.

In case of inline application a vacuum SSP reactor (deCON, viscoSTAR) can be installed before the production extruder instead of a conventional dryer. In this step, post-consumer sheet flakes – or also a mixture of flakes from preforms and post-consumer bottles – are dried, decontaminated and their IV increased before being processed on the production line. The higher IV of the final sheet leads to better and faster processing of the material in thermoforming machines with fewer brittle cups or trays.

The combination of recycling step and production step results in competitive investment costs and helps to reduce energy consumption and maintenance while remaining user-friendly. (Brochure)

=== 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”. What comes out of the recycling process can be a better quality PET than what went in. In order for rPET to meet the high intrinsic viscosity (IV) required for strapping bands, it undergoes a solid state polycondensation (SSP) process.
