24 TRADE SHOW REVIEW PETplanet Insider Vol. 24 No. 04/23 www.petpla.net PRSE, RAI, Amsterdam, Netherlands May 10-11, 2023 The Plastics Recycling Show Europe is designed specifically for plastics recycling professionals. It brings together key players from the plastics and recycling sectors to showcase innovative technology, share best practice, network and do business. Over 250 companies and organisations from across Europe have already signed up to exhibit. A new chemical recycling feature area in Hall 11 will guide visitors through the history of and latest innovations in chemical recycling in a timeline with video displays.

The Omni recycling systems consist of a variety of machines from Gneuss’ portfolio, customised to a specific material and application, utilising Gneuss’ established devolatilisation and filtration technologies. The Omni line is equipped with a 3C rotary feeder, an MRS extrusion system, a fully automated RSFgenius melt filtration system, a VIS online viscometer and downstream equipment. Polymer reclaim such as fibre waste, thin film or other low bulk density waste is fed into the Gneuss 3C rotary feeder. PET postconsumer and industrial waste does not require thermal pre-treatment. A conveyor belt feeds the material into the 3C rotary feeder, which cuts, compacts and conditions the material and feeds it directly into the MRS extruder. The MRS extrusion technology in the Omni recycling line is based on conventional single-screw technology, but is equipped with a multi-screw degassing section. The degassing section of the patented process unit consists of an enlarged single screw drum with a series of satellite screws that rotate in the opposite direction of the extruder barrel, creating a large melt surface area and ensuring rapid surface exchange. This provides unprecedented melt phase degassing performance with minimal material stress, says Gneuss. Multiple letters of non-objection (LNOs) from the FDA, Efsa compliance and local approvals in Latin America confirm the high decontamination performance of the technology. After passing through the MRS extruder, the polymer melt is filtered by the efficient, self-cleaning Gneuss RSFgenius melt filtration system. It ensures that fine filtration is possible without pressure or flow disturbances and with minimal polymer losses, even at high contamination levels. The RSFgenius works with an integrated backflush system for self-cleaning of the screens for demanding applications and high quality requirements. The Omniboost is specifically designed to recycle PET waste. The integrated Gneuss Jump polyreactor raises the IV value to the desired level within minutes. After leaving the MRS extruder, the polymer flows directly into the reactor in the melt phase, while the viscosity of the melt is tightly controlled. By controlling the vacuum, residence time and surface exchange rate in the reactor vessel, the viscosity is adjust to the desired level. With a consistent set viscosity, the melt can then be fed directly into the production process. www.gneuss.com GNEUSS Booth B12
