31 EVENT PREVIEW PETplanet Insider Vol. 25 No. 03/24 www.petpla.net Devolatilisation and decontamination technologies for recycling applications Gneuss introduces its latest Omni recycling machines at Chinaplas, offering devolatilisation and decontamination technologies for various recycling applications. These machines, integrated with Gneuss MRS Extrusion Technology, are designed for closed-loop recycling. Accompanied by rotary filtration systems, advanced vacuum technology, and online viscosity measurement tools, these recycling lines can be tailored for specific materials, ensuring high-quality output. With FDA and Efsa compliance and local approvals, the efficiency of the decontamination process is validated. The Omni series handles various materials including PET scrap, PS, PP, PE, and PLA, with applications ranging from thermoformed sheet production to odour reduction in polymers. Its compact design and automated control ensure operational flexibility and energy efficiency, reducing both operational costs and CO2 footprint. The MRS extruder features a multiple screw section for devolatilisation. This design is claimed to increase the surface area exchange rate, resulting in thorough decontamination and good mechanical properties of recycled materials. Additionally, Gneuss’ proprietary vacuum systems extract volatile impurities, while the RSFgenius filtration technology offers self-cleaning capabilities and filtration finenesses below 10 microns (1,200mesh). The system can be retrofitted to existing lines, enabling the use of more contaminated materials without compromising quality. The inclusion of the Online Viscometer VIS enhances quality control by precisely measuring viscosity during processing. Gneuss also provides flexible and digitally integrated measurement technologies tailored to specific industrial needs, ensuring fast delivery and compliance with quality standards. www.gneuss.com Ink removal in plastics recycling plants Inks and coatings play a crucial role in packaging but pose challenges in transforming packaging waste into a valuable resource. The growing demand for high-quality recycled materials underscores the need for efficient ink removal processes in recycling plants. Sorema has introduced a de-inking process upstream of extrusion, ensuring minimal ink residues in recycled materials. This advanced washing system, developed by the company, combines several factors. These include the feeding of the incoming material with volumetric or gravimetric dosage, the controlled and independent dosage of chemical additives and a high friction of the material in hot water with a defined residence time adjustable to each specific inks and material. In this way, customers have the opportunity to wash rigid and flexible plastic materials on a single plant. The recycling process is then completed by one or more rinsing and drying phases of the flakes, before an eventual extrusion into granules. The de-inking process, primarily applied to post-industrial waste, is being explored for postconsumer waste recycling plants. The company’s laboratory in Alzate Brianza offers testing facilities for customers to validate the process with their products and optimise chemical formulations and washing times. These tests can also be completed with the “in-house” extrusion phase to verify the achieved results. Sorema provides complete turnkey washing and recycling plants, managing all stages of the process, including wastewater treatment. Collaborating with sister company Teknodepurazioni Aquae, Sorema offers integrated solutions for wastewater treatment, incorporating mechanical filtration processes with high-speed centrifuges, sedimentation with chemical adjuvants and purification with ozone and activated carbon treatments. www.sorema.it www.previero.it Sorema Hall 2.1 Booth C74 Gneuss Hall 2.1 Booth H26 product development caps & closures design high cavitation moulds multi-component moulds closure production systems after sales service +43 5572 7272-0 | sales@z-moulds.com | www.z-moulds.com z NEXT SHOWS CHINAPLAS 2024 Shanghai, April 23-26th, 2.1A52 NPE 2024 Orlando, May 6-10th, W7443C INSPIRING PARTNER WORLDS FIRST 128 CAVITIES BELOW 2 SEC.
