Recycled PET products show a drop of up to 90% in CO 2 emis- sions compared to virgin PET. Most major brands using plastics in their supply chains have started to evaluate their carbon footprint and take mitigating actions like packaging redesign and light-weighting, reducing the use for virgin plastics, increasing reusability, and setting tar- gets for minimum recycled plastic content. As brands strive to meet their targets, they are collectively expanding demand and increasingly competing for available rPET. Another factor driving the demand for and supply of rPET are the new regulations and taxes on packaging made from virgin plastics / single-use plas- tics packaging. Rising rPET demand and prices are incentivizing investments in new recycling capacity – Europe has seen a 21% increase in the installed capacity for PET recycling – according to a report by Plastics Recyclers Europe, PETCORE Europe, Natural Mineral Water Europe (NMWE), and UNESDA Soft Drinks Europe – at the same time global rPET capacity is forecast to boom over the next five years. This “run” towards ever increasingly demand for rPET, has led producers of PET packaging products (both food grade and non- food grade applications) to look for more contaminated sources of PET waste. ➠ FIMIC SRL Via Ospitale, 44, 35010 Carmignano di Brenta (PD), Italy www.fimic.it FIMIC’s melt filters are recognized as one of the best filtra- tion technologies de- dicated to contami- nated post-consu- mer plastics; to reach high quality recycled plastics from more contaminated waste streams, automatic technologies are needed to filter out impurities and conta- minations from the melt flow. FIMIC has been working many years now on impro- ving its filtration technologies in order to meet and satisfy the needs (ever increasing quality needs, dif- ferent materials characteristics) of recyclers, and expanding its technology to applications that previously did not require the use of continuous scraping melt filters such as, precisely, PET. FIMIC has already installed two units (RAS-type filters) on PET recycling lines to work with more contaminated PET waste streams, i.e. not coming from hot-washed bottle flakes only, such as for example PET lumps from petrochemical waste or from strapping production, waste fibers as well as PET straps. In these cases the contamination of the input material was way higher than the typical “ppm” contaminations used for food grade applications, reaching levels as high as 5%. The benefits and the advantages of a continuous scraping filtration were significant. Dedicated to different end applications, these filter units are working with an excellent performance and great qua- lity results in both cases: as a pre-filter in the first project (ap- plied filtration is 150 or 120 micron on laser screen) and as the only filtration step in the second one (applied filtration is 80 mi- cron on laser screen). The respective output performances are 2.000 kg/h and 700 kg/h, at very different and sometimes in- consistent iV levels. At the same time, FIMIC has increased the amount of units in- stalled for the recycling of soft PVC and, also in this case FIMIC melt filters are confirmed to be a winning choice due to the sen- sitivity of the PVC during the recycling process, as it allows the material to flow without stagnating and therefore without de- grading. Most recently, FIMIC has been testing an alternative so- lution to be applied to hard PVC which we know is one of the most degradation-sensitive as well as the stiffest material in the recycling market. The continuous research for innovation and passion for impro- vement keep FIMIC constantly growing and developing innova- tive technologies and tailored solutions in an increasingly demanding market to achieve its mission worldwide: the pro- tection of the environment through the proper recycling of plas- tic and its optimal reuse.
