Development of a recycling solution for waste Thermoset Material: waste source study, comminution scheme and filler characterization
Journal of Material Cycles and Waste Management, 2018Co-Authors: Fabien Bernardeau, Didier Perrin, Anne-sophie Caro-bretelle, Jean-charles Benezet, Patrick IennyAbstract:End of life electrical equipment is a continuously increasing source of waste in our modern society, and constitute an environmental problem. Understanding this type of waste flow is important to devise proper dismantlement and sorting strategies, and to maximize the Material recovery rate and valorization. In this work, a waste pool constituted of electrical meter was studied. The specificities of this equipment in term of design were enlightened, and the overall Material composition was determined. An emphasis was put on the characterization of the plastic fraction, both in term of plastic type and presence of regulated substances. It revealed that this fraction is mostly composed of phenolic molding compound (PMC), a Thermoset Material, which is troublesome in term of recycling. A Material valorization solution through mechanical recycling is proposed, consisting in using PMC as functional filler in a thermoplastic matrix. A comminution scheme to obtain such filler is presented in this work, and the comminuted products are characterized. Through 2 or 3 steps of comminution, particle size below 50 µm can be obtained, which is expected to be a sufficient size for incorporation in a thermoplastic matrix.

Valorization of waste Thermoset Material as a filler in thermoplastic: Mechanical properties of phenolic molding compound waste-filled PP composites
Journal of Applied Polymer Science, 2018Co-Authors: Fabien Bernardeau, Didier Perrin, Jean-charles Benezet, Anne-sophie Caro, Patrick IennyAbstract:As most Thermoset Material, phenolic molding compound (PMC) wastes are an environmental problem. Very few recycling solutions have been proposed so far for this type of Material. A mechanical recycling method to valorize these Materials is proposed in this work. It relies on the use of phenolic waste as filler in thermoplastic. Such phenolic filler can increase mechanical properties (tensile, flexural) of the matrix, and be used in substitution of traditional particulate fillers such as calcium carbonate or talc. In this study, several morphological parameters influencing the final mechanical properties of a PMC‐filled polypropylene (PP) micro‐composite are studied, such as filler loading rate, particles size distribution of the filler, and interfacial adhesion between the filler and the matrix. Some structural parameters are also studied and linked with mechanical properties, such as dispersion of the filler and crystallinity of the matrix. Finally, the properties of PMC‐filled PP are compared with CaCO3‐ and talc‐filled PP.

Natural tannin–furanic Thermosetting moulding plastics
RSC Advances, 2013Co-Authors: Xinjun Li, Alix Sauget, Arnaud Nicollin, Xiaojian Zhou, Antonio Pizzi, Luc DelmotteAbstract:A new 100% biosourced Thermosetting plastic Material, named condensed tannin–furanic Thermoset is prepared and characterized in this paper. This new Material is synthesized from tannin and furfuryl alcohol, both of which are inexpensive plant-derived chemicals. The co-polymerization process of these two chemicals was studied by 13C nuclear magnetic resonance (NMR) and matrix-assisted laser desorption–ionization time-of-flight (MALDI-ToF) mass spectroscopy. The 100% renewable bioresourced tannin–furanic Thermosetting resin was found to have a glass transition temperature as high as 211 °C, and a 95% weight loss temperature of 244 °C and 240 °C in a nitrogen and in an air atmosphere, respectively. The char yield is as high as 52%. Moreover, this new Thermoset Material shows excellent mechanical properties: a Brinell hardness of 23 HBS, which is higher than commercial acrylic, polyvinyl chloride, and a little lower than that of solid polystyrene. The compressive break strength was found to be as high as 194.4 MPa, thus higher than that of filled phenolic resins, and much higher than that of solid polystyrene and of acetal resins.
