RPC's Extrusion Line Saves Energy While Producing Food Grade Sheets from PCR PET

Published on 2011-06-13. Author : SpecialChem

RPC Cobelplast-Montonate is investing in a new state-of-the-art extrusion line which will further contribute to a lowering of CO2 emissions and reduction in energy consumption at the site.

The company developed the first co-rotating twin-screw extruder for PET sheet in 2002, which subsequently won an innovation technology prize from the Italian government. Twin-screw technology has since become the most widespread process for the production of PET sheet, thanks both to its eco-friendly performance and its ability to create high quality and visually appealing sheet that incorporates post-consumer recycled PET.

In terms of its sustainable benefits, the technology offers an approximate 35% reduction in energy consumption compared to the single-screw process. Equally important, it allows manufacturers to directly process up to 100% recycled material without the need for pre-drying equipment, thus delivering further energy savings as well as improving the color of the sheet.

The new plant at RPC Cobelplast-Montonate will also be equipped with a very high performance filtration and vacuum system, which is able to produce a food grade sheet by feeding post-consumer PET directly into the extruder.
