Extrusion International 4-2018

26 Extrusion International 4/2018 INDUSTRIAL RECYCLING – CASE STUDY Trioplast France produces agricultural plastics films in Pouancé. The LDPE and LLDPE production and post usedwaste is recycled on two EREMA 1514 TVEplus ® machines. The regranulates are mainly used for wide sheet film production, sold under the TRIOCARE brand.Additional material sources for the recycling process include production and commercial waste from Tri- oplast and from other European suppliers.The recycling pro- cess faces a number of challenges due to many various criteria such as prints, contaminants or the degree of moisture through transport and frequent outdoor storage.Despitethe consider- ably varying input material, the quality of the regranulates pro- ducedmust be ensured at the end of the recycling process. Trioplast equipped one of its EREMA 1514 TVEplus ® machines with a new process for quality monitoring – QualityOn:MVR. JérômeKlaeyle, Recycling manager of Trioplast France, refers to QualityOn:MVRas an investment in the decisive lead.”Trioplast stands for high-quality filmwith our premiumTRIOCARE brand. Thanks to QualityOn:MVR we achieve a previously unattained level of process reliability in recyclingwhichwedefinitely consid- er to be a lead over other film producers.We already determine the quality of the recyclate during the recycling process, unlike others who don’t do this until after.” Variable input – stable output The QualityOn:MVR measuring unit is mounted directly on the recycling system and measures the MVR value in real time every couple of minutes – depending on the viscosity of the melt.The data is exported automatically according to the customer’s wish- es and can be called up at any time.A message is given for the user as soon as the values measured leave the defined tolerance range and the user can then remove the material with noncon- formingMVR values immediately from the current process. Customers who recycle commercial waste benefit in particular from QualityOn:MVR measuring technology.Developed origi- nally for the increased demands in post-consumer recycling, it is insensitive to contaminant particles from 100 to 1,000 µm – a clear advantage over onlinemeasuring systems with gear pump technology. About Trioplast Founded in Sweden in 1965 the group has 1,250 employees working in ten production sites and sales companies in Swe- den (7), Denmark (1) and France (2) and sales agencies in Ger- many, England, Finland and Norway.Typical film products can be found in the industrial, agricultural, food and also hygiene sectors. The Trioplast Grouphas a total of around 30 EREMA sys- tems and one ISECmachine from PURE LOOP.

As a major raw material client of polyethylene, the Swedish group sees its responsibility in the efficient use of resources, processes production and commercial waste on a total of around 30 EREMA recycling systems.At the Frenchplant inPouancé (located in thewest coastarea) thenewtechnology investmentQualityOn:MVR guarantees for the first time permanent quality control of the recycling process – directly on the machine
