K2019 | SHOW REVIEW


Netting the benefits of recycling


A project to recycle waste fishing ropes and nets in Chile was showcased by ExxonMobil, which pro- vided its expertise and Vistamaxx material for the Atando Cabos (literally tie rope) scheme.


Established in 2017 by plastics industry executives Francisco Cruz and Julio Compagnon, who are both directors of Chilean recycling and injection moulding company Comberplast, Atando Cabos began with a collection system for ropes and used fishing gear run by local communities in the Chilean Patagonia region,


Returnable crates produced by Comberplast from recycled PE/ PP fishing gear using ExxonMobil’s Vistamaxx compatibiliser


on the southern tip of South America. These communities see the collection work positively, said Cruz, ensuring confidence of a steady supply. The reprocessing


obstacle that had to be addressed was that the waste was an incompatible mix of PE and PP, which was overcome by ExxonMobil with its Vistamaxx compati- bilising additive. The initiative is now successfully


producing a recycled PE/PP compound that is being used to injection mould robust 1.3kg crates for transit packaging in various end markets – one custom- er is using the crate in the Netherlands in the flower trade, for example. Since the project began, 1,200 tonnes of the PE-PP compound have been produced. Cruz said the company is targeting an annual production rate of 2,000 tonnes, with the aim of selling the compound into the international market. � www.atandocabos.clwww.exxonmobil.com


Sustainability was very much the theme for K2019. You can find more news about the key recycling developments in the latest edition of our sister publication Plastics Recycling World.


of its process of range standardisation. Customers can, however, still buy a full-Scheer design. The company also previewed the Gala Color &


Pellet Control system, which uses technology developed by Cologne, Germany-based ROC (Rapid Optical Control), the latest addition to the Maag Group that was acquired just before K began. Combining colour control, colour dosing and automatic sampling in a single system, it is intended to improve colour management and quality control in plastics extrusion, compounding, and recycling applications. “It measures the colour and the pellet specification


on the fly,” said Michael Eloo, General Manager of Maag’s underwater pelletising systems business. “You measure every individual pellet so if you have any problems with your process you will see it.” � www.maag.com


ProTec Polymer Processing detailed an upgrade for its LFT compounding lines allowing production rates to be increased from 30 to 50 m/min without loss of pellet quality or physical performance. According to Karin Luxem, Area Sales Manager


Asia Pacific for the company’s LFT production systems, the move responds to a clear demand

from customers – particularly those producing PP-based LFT compounds – for higher production outputs and reduced manufacturing costs. Luxem said achieving the gain without sacrific- ing quality required a full redesign of the produc- tion technology. “The key issue is to coat each individual filament so you pull the polymer off the fibre. If the coating is not good enough you lose performance,” she said. “You have to control each single part of the line to get the quality – one key element is the die but it is not the only element. The key change in high speed production is the handling of the fibre in front of the die.” The new system includes redesigned fibre


pre-heating, an improved die, enhanced cooling, and an upgraded puller and pelletiser. The software control has also been updated to provide fully intelligent “balancing” of each section of the line for changes to pellet length or line speed. Most Protec LFT lines are producing PP-based


glass reinforced compounds. However, the equipment can handle PA 6 and 66, POM, PC, PPS and renewable polymers such as PLA while reinforcement options include carbon, aramid and steel. � www.sp-protec.com
