“…On the opposite, the pulp-rich fraction (wP) was considerably darker, with a lower L* value (34.9), and browner with a higher value of a* (9.2) and lower value of b* (11.6) ( Table 1). It can be concluded, as expected, that washing in water is an efficient treatment to produce contrasted fractions, what justifies its applicationby several authors to remove the pulp from the stone [11,12,13].

“…It is worth noting that the stone-rich fraction obtained by washing in water was the most polar of all the fractions, with the highest γ p value (14.1 mJ.m This certainly justifies the necessity of applying post-treatments in order to modify its surface properties and thus improve its affinity with apolar polymer matrices [2,4,11,12]. Table 4.…”

“…Existing pre-treatments used to separate the pulp from the olive stone are based on chemical multistep processes consuming large amounts of water and chemicals and generating effluents that have to be treated. They include cleaning and washing with hot water [2,3,11,12,13], with hot water and solvent (acetone-hexane) to remove the pulp [14], or hot treatment by solvent (acetone and/or hexane) followed by separation with ventilation of the stone from the pulp [4,5].To raise this bottleneck and allow a better exploitation of OP, it would be more relevant to apply a non-polluting fractionation process in order to produce contrasted powders whose properties will be adapted to composite applications.…”

“…It is 380 °C for virgin PS, 358.9 °C, 329.1 °C for composites at a loading rate of 10 and 30% respectively. This decrease attributed to the presence of cellulose, hemicellulose and lignin in the flour [26]. Ataround484°C, stability is recorded attributed to the formation of mineral residue.…”

This paper aims to disclose the effects of surface modification on the morphological, thermal and mechanical properties of olive pomace flour (OPF) reinforced polystyrene composites. First, the OPF was treated by the silane coupling agent: 3-(Trimethoxysilyl) propyl methacrylate (TMSPMA). Then, the treated OPF was added to polystyrene (PS) at different ratios, creating the composite samples. The structural and property changes resulting from this treatment were observed and discussed through Fourier transform infrared spectroscopy (FTIR), morphological analysis, thermal analysis and mechanical analysis. The results show that, with the growing OPF content, the tensile strength and elongation at break of the composites decreased, while the Young's modulus increased; the composites prepared with the silane coupling agent were more thermally stable than the untreated composites; the filler-matrix interaction was improved through the surface modification of the OPF by the TMSPMA).

“…This waste has already been used in polymers as polypropylene, poly(3‐hydroxybutyrate‐ co ‐3‐hydroxyvalerate), chitosan, plasticized wheat gluten, and mechanical, thermal properties as well as matrix‐OP compatibility of resulting composites, were investigated. In order to select more suitable fractions, fractionation of OP was also carried out and its influence on composition and properties was studied …”

Olive pomace (OP) is a lignocellulosic waste from olive oil industry. In order to valorize these wastes as flame retardant (FR) fillers into polymers, OP residues are milled and screened into three different fractions. Two strategies are then investigated. The first one is to modify OP particles by phosphorus molecules using radiation grafting as already done successfully with flax. Nevertheless, pyrolysis combustion flow calorimetry analyses show that the introduction of phosphorus does not promote charring of OP and flame retardancy is not significantly improved whichever the considered fraction. The second strategy is to replace pentaerythritol by OP as char source into well-known FR systems based on ammonium polyphosphate. The incorporation of such system into ethylene-vinyl acetate copolymer leads to satisfying FR performances according to cone calorimeter tests. Moreover, the presence of high amount of extractives into OP such as oleic acid does not appear detrimental.
