Our polymer material and processing industry heavily relies on single- and twin-screw extrusion technology. To facilitate a circular economy technological upgrades, bridging experimental characterization techniques and the predictive power of modeling and software tools are although indispensable. The current work highlights engineering challenges and solution strategies to make (reactive) extrusion technology more sustainable and reliable. Molecular scale-driven case studies are included dealing with (i) energy and residence time optimization, (ii) the enlargement of the pool of polymers to be processed or synthesized (e.g. biopolymers and more well-defined compatibilizers), and (iii) polymer recycling applications, both chemical and mechanical. These case studies consider linear, branched, as well as cross-linked polymers.

我们的聚合物材料和加工业严重依赖单螺杆和双螺杆挤出技术。为了促进循环经济技术升级，连接实验表征技术以及建模和软件工具的预测能力是必不可少的。目前的工作重点介绍了工程挑战和解决方案策略，以使（反应）挤出技术更加可持续和可靠。分子规模驱动的案例研究包括处理（ i）能量和停留时间优化，（ii）扩大待加工或合成的聚合物库（例如生物聚合物和更明确的增容剂），以及（iii））聚合物回收应用，包括化学和机械。这些案例研究考虑了线性、支化和交联聚合物。
