Optimal Chemical Recycling
Input material streams in chemical recycling vary widely in terms of polymer type, material shape and level of contamination. Moist and contaminated materials with a low bulk density place particularly high demands on the system that feeds the material into the chemical recycling process. Thanks to its broad technology portfolio, it offers custom-built solutions to this challenge. This means that the extrusion systems are precisely designed to meet the requirements of each input stream – incorporating a high degree of flexibility to allow for any variances that occur in the material being fed into the system. Systems range from single-screw melt extruders with preconditioning unit (PCU), shredder-extruder combinations and vacuum-assisted extrusion solutions, through to cascade solutions with single- or twin-screw extrusion.
HDPE, Regrind Recycling
Top recycled pellets from thick-walled regrind. For end products with best performance properties and a particularly high recyclate content. It offers the ideal solution: extremely gentle processing in combination with high-performance filtration. Thanks to the thorough warming-through of the input material in the preconditioning unit and a particularly gentle operation of the universal screw, polymers with an extremely wide range of melting points and energy contents can be universally processed. At the same time, foreign material is effectively removed. For end products with top functional characteristics in terms of mechanical properties, surface quality, dyeability, odour, etc.
