PP-recyclates characterization after different sampling and recycling strategies – TGA data Authors: A. Martínez García, A. Ibáñez García, M.A. León Cabezas Innovative Materials and Manufacturing Area, AIJU, Avda. de la Industria, 23 03440 Ibi (Alicante), Spain Contact Information email: sunymartinez@aiju.es tel: +34 965554475 This dataset contains raw TGA data of PP-recyclates from different recycling strategies following different sampling strategies. The purpose of this analysis is to evaluate the efficiency of the different recycling strategies and the quality of the resulting recyclates in combination with other analysis techniques. Recycling strategies followed: 1) Purification of PP-rich post-consumer waste using supercritical CO2 (scCO2). scCO2 does not alter particle size or shape. The waste material was subjected to scCO2 treatment in two ways. The first method involved directly treating the flake material, which was subsequently ground. These samples are labelled CO-PP03RE-SC01GR. The second approach aimed to investigate whether cleaning efficiency depends on particle size. The flakes were ground first, and scCO2 was then applied to the particles, resulting in a sample identified as CO-PP03RE-GRSC01. Homogenous powder was obtained in both cases and five samples were analysed following the DSC For the sample preparation, the flakes of the waste were ground using a ring sieve mill (ZM 300, Retsch, Haan, Germany). Data from this approach are given in: PP recyclates after sc-CO2 recycling-TGA.xlsx 2) Purification of PP-rich post-consumer waste using solvent-based CreaSolv® process, developed by Fraunhofer IVV. The solvent-based recycling process results in more homogeneous recyclates by dissolving the entire sample, and selectively precipitating the desired purified polymer, with the potential of removal of unwanted components. The waste material was subjected to solvent-based recycling treatment in two ways. The first method includes additional purification with a solid-liquid separation step, referred ... |
