MONITORING AND TESTING | TECHNOLOGY
Quality assessment is essential all along the plastics recycling value chain. Mark Holmes finds out how technology and testing companies are helping recyclers at the material and process stages
Helping recyclers to keep on top of quality
The circular economy and closed plastics cycles are dominating the agenda and recycling is at the centre of these developments. Companies from all areas of the plastics value chain are collaborating to ensure that materials are designed with recy- cling in mind, can be readily collected and effi- ciently processed and recycled into plastics that are required to meet ever higher levels of quality. At K 2019 recycling machinery supplier Erema highlighted the Circonomic Centre, where in cooperation with customers and partner compa- nies from many points in the value chain, the machinery group presented over 30 projects and demonstrated live recycling to show how plastics cycles can be successfully closed. “It’s about integrating recycling know-how into the plastics value chain so that our industry, as well as the environment and our society, can benefit from it ecologically and economically,” says Manfred Hackl, CEO of Erema Group. Erema adds that these projects gave impetus to new circular economy projects. In the course of the

fair, Erema recycled 14 different plastic waste materials into high-quality recycled pellets, some of which were processed directly into new end products. A wide range of high quality products containing up to 100% recycled materials were on display. The recycling line in the Circonomic Centre was an Intarema TVEplus equipped with a Quali- tyOn package for continuous measurement of colour, MVR and polymer composition and integra- tion into the re360 Manufacturing Execution System. Fundamental to these closed loop projects
producing high quality recycled plastics cost-effec- tively in the quantities required by the industry, are inspection and testing technologies that meet these demands in plastics recycling. Erema has developed the QualityOn: Polyscan, which now permits polymer composition measurement directly at the recycling machine. The demand for quality in plastics recycling is increasing constantly, says the company. This means that achieving a circular economy for plastics relies on higher proportions of recycled pellets being used in end
