ONLINE INSPECTION | TECHNOLOGY


The plastics recycling operation can benefit from continuous monitoring of product quality, as well as online machinery support in the manufacturing environment. Mark Holmes reports


Maintaining quality using online controls


Manufacturers of plastics recycling systems, as well as suppliers of pilot and laboratory systems, have developed a number of online inspection and testing systems for the plastics recycling industry. These systems include ones for ensuring that the quality of the recycled plastics achieve a consistent and designated level of quality, through to process monitoring systems that provide recyclers with the required support in production to ensure efficient and cost-effective recycling and reprocessing. Erema has developed online measuring technology that can monitor colour and melt volume rate (MVR) values while a recycling machine is processing. The company says that the QualityON:MVR technology guarantees permanent quality control of the recycling process directly on the machine. QualityOn:MVR measuring technol- ogy has recently been used by the Trioplast

Group, an international producer of agricultural plastics film with an annual turnover of around €400m. The group has 1,250 employees working in ten production sites and sales companies in Sweden, Denmark and France, with sales agencies in Germany, England, Finland and Norway. The Swedish group says it recognises its responsibilities in the efficient use of resources, processes, produc- tion and commercial waste and it operates around 30 Erema recycling systems. The group’s polyethylene film products can be found in the industrial, agricultural, food and hygiene sectors. Trioplast France produces agricul- tural plastic films at its plant in Pouancé, where its investment in QualityOn:MVR is providing perma- nent quality control of the recycling process for the first time. The LDPE and LLDPE production and post-use waste is recycled on two Erema 1514 TVEplus machines. The regranulates are mainly
