RECYCLING: Recycling Systems Enhanced for Higher Output

Starlinger & Co.

Starlinger & Co. Ges.m.b.H. in Austria (U.S. office in Greenville, S.C.) has recently unveiled two new recycling systems: recoSTAR PET 330 for post-consumer PET recycling, and recoSTAR universal 165 for hard-to-grind, high-volume scrap.

The recoSTAR PET 330 relies on two 165-mm single-screw extruders mounted parallel on a common frame (see photo). Upstream and downstream equipment is sized so that only one predrying unit, filter, and pelletizer are needed for the two extruders, which helps to keep costs down. The line can reportedly produce more than 48 million lb/yr of bottle grade PET with virgin-like characteristics.

The first recoSTAR PET 330 was delivered early last year to Continuum Recycling in Hemswell, Lincolnshire, U.K., the joint venture company formed between Coca-Cola Enterprises (CCE) and British plastics recycler ECO Plastics. It has been running since May, producing RPET for use in CCE’s PET packaging in Great Britain.

The recoSTAR universal 165 has been redesigned to handle all sorts of hard-to-process materials, such as clean in-house scrap, washed and dried post-consumer waste, lightweight film, and hard-to-grind molded parts. The unit offers a flexible modular design, operator and maintenance friendliness, efficient material preparation, feeding control for consistency and process stability, and consistently high pellet quality. Capacity is up to 22 million lb/yr.
