Food-grade 100% rPET preforms from recycled PET flakes
The earth'southward start XTREME Renew Flakes to Preform System, which direct produces new, food-grade 100% rPET preforms from recycled PET flakes in a single process step, was recently presented with a Globe Star Packaging Accolade in Prague. EREMA, SIPA, Kyoei Industry and Suntory, four companies involved in developing the organisation, received the honor for the example of a closed plastic loop.
The World Star Packaging Award recognizes excellence in packaging solutions from around the earth that gear up international standards for the packaging industry attributable to their design or the manner they are manufactured. EREMA won the honor in cooperation with SIPA, the Italian manufacturer of PET packaging solutions, too equally the plastics recycling company Kyoei and the beverage company Suntory, both based in Japan.
Four pioneers successfully bundle their know-how
The articulation development of the procedure was initiated in 2014, by Kyoei Industry and Suntory. The procedure is based on the combination of EREMA's proven VACUREMA bottle to bottle technology, enhanced for this application with SIPA's XTREME Renew Preform Production System. This plant network produces new, nutrient-form PET preforms directly from PET flakes. Later being in operation at Kyoei Manufacture in Kasama (Nippon) for almost a year, the Flakes to Preform Arrangement not only outputs preforms with quality values, but also delivers ecological and economical performance. The almanac production capacity of this establish is 300 million containers. Suntory, the Japanese drinks manufacturer, is the customer for this output.
The VACUREMA part of the plant decontaminates the flakes and increases the viscosity of the input material, which is then melted and filtered. The food-grade melt is then fed directly into the XTREME injection molding car supplied by SIPA. With this system, a further melting process (i.eastward., the melting of the rPET pellets, which is necessary in conventional processes) is no longer required. This in turn eliminates the risk of yellowing and the formation of volatile organic compounds. Bottles made from these preforms therefore differ significantly in their appearance to other 100% rPET products. "If the quality of the washed flakes is correct, the inline preforms don't need to shy away from being compared to injection-molded virgin products," says Christoph Woess, business development managing director for the bottle applications at EREMA.
Beneficial in both ecological and economic terms
The combination of 4 process steps – decontamination, IV stabilization, melt filtration and injection stamping – in ane organization reduces energy consumption past 30% compared to conventional systems. CO2 emissions are likewise reduced by 25% and are therefore significantly lower than with conventional PET bottle product from rPET raw material. Since no PET-Pellets are produced, boosted dryers and storage areas are no longer necessary, resulting in lower costs.
"Our cooperation shows that combining the expertise of plastics recycling companies, automobile manufacturers and brands makes a functioning circular economy possible," say the people representing the iv participating companies, pleased about the successful implementation of the project.
