26 TRADE SHOW PREVIEW PETplanet Insider Vol. 24 No. 09/23 www.petpla.net Gneuss - hall A6 booth 6501 Clean recycling qualities in just one process step Gneuss will feature its Omni recycling system, consisting basically of an MRS extrusion system, a fully automatic RSFgenius melt filtration system, an online viscometer and optionally a 3C rotary feeder. The technological components of the system have been matched to each other in such a way as to achieve a high level of performance, achieving clean recycling qualities in just one process step, according to Gneuss. Polymer reclaim such as fibre waste, thin film or other low bulk density waste is fed into the Gneuss 3C rotary feeder. PET post-consumer 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 is claimed to provide unprecedented melt phase degassing performance with minimal material stress. 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. Af ter passing through the MRS extruder, the polymer melt is filtered by the self-cleaning Gneuss RSFgenius melt filtration system. This system is claimed to ensure 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. If the recycled material to be processed requires a particularly high decontamination and degassing performance, the Omnimax recycling system is used with a longer, modified version of the multi rotation section in the MRS extruder, which ensures both a longer residence time of the material and a disproportionately high surface area exchange under vacuum. The Omniboost recycling system 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 (FU UP LOPX PVS .&%*$"- *.- JOTQFDUJPO TZTUFN 888 */53"7*4 $0.
