“…Several mineral fillers references were also involved: XP12-5630 kaolin (IMERYS), Omya BL calcite (Omya), Luzenac HAR T84 talc (IMERYS) and It is the case with sink-float tanks (Gent et al, 2009) where sorting is based on density differences. Other examples are froth flotation for surface tension (Wang et al, 2015), trommels for granulometry (Ashkiki et al, 2019), magnetic overhead belts and Eddy current for (para)magnetic properties (Krivtsova et al, 2009). Sorting is indirect when identification and separation are performed through two different steps (Gundupalli et al, 2017).…”

Plastic recycling is mainly limited by their sorting as their natures, forms and formulation are very numerous and most of them are strongly incompatible, leading to poor mechanical properties. Several industrial sorting technologies exist, and others are in development. However, each of them has drawbacks. Especially, NIR-HSI (Near-Infrared Hyperspectral Imagery) is limited by the use of carbon black, mainly as a pigment and UV agent in the case of thermoplastics. MIR-HSI (Mid-Infrared) could be a suitable and viable alternative to resolve this issue. Hence, this work, based on laboratory FTIR-ATR (Fourier-Transform Infrared Attenuated Total Reflection), focuses on possible sources of spectral alteration, which could impair identification of usual polymers using industrial MIR-HSI. It aims to help simple and rapid laboratory characterization and give tools to avoid misidentification or enable specific segregation during industrial sorting. First, acquisition parameters were degraded to simulate those imposed by industrial conditions: short acquisition time, diminished resolution and blank defaults. Then, impact on formulations of usual WEEE (Waste of Electric and Electrical Equipment) plastics were evaluated, with PE, PP, ABS and HIPS as matrices, and carbon black (at different concentrations), calcite, talc, titanium oxide and some flame retardants as additives. Several patterns found in homemade standard samples were recognized within a stock of about one hundred of real waste samples.

Electromagnetic fields have been widely applied in the field of materials processing, preparation, and analysis. The effectiveness during such processing is, however, highly dependent on the physics of the applied electromagnetic field as well as the electromagnetic responses from the materials. In order to improve the efficiency of electromagnetic field processing, understanding the fundamentals as well as the engineering of the corresponding electromagnetic effects is crucial. Focusing on metallic materials, this research gives a critical overview and discussion on different electromagnetic effects. Subsequently, the electromagnetic responses in different electromagnetic technologies are further discussed. Specifically, the industrial application potential for inclusion removal from liquid metals is evaluated and the energy coefficient is noticed to be substantially improved by increasing the magnetic flux density.
