The aim of this paper is to develop an innovative Lean Maintenance model in order to optimize the process flow and reduce or eliminate scraps and work-in-progress (WIP) in a manufacturing context. To achieve these objectives has been formulated a new method, called Lean Root Cause & Defect Analysis (LRCDA), which merges the process steps of the existing Root Cause & Failure Analysis (RCFA) tech...

In this work, an additive model for the prediction of rheological and mechanical properties monopolymer blends made by virgin reprocessed components is proposed. A polypropylene sample has been more times in extruder have prepared simulating industrial process. The scraps are exposed to regrinding melt before mixing with polymer. polymer is, then, subjected some thermomechanical degradation. Rh...

A key element for realizing long term sustainable use of any metal will be a robust secondary recovery industry. Secondary recovery forestalls depletion of non-renewable resources and avoids the deleterious effects of extraction and winning (albeit by substituting some effects of its own). For most metals, the latter provides strong motivation for recycling; for light metals, like aluminum, the...
