“…The incorporation of RH or/and VS is investigated to have little effect on the melting temperature of PP. Small variation in the melting temperature of PP indicates that the crystal size of PP did not change remarkably [25]. As can be seen from Table 5, all Tc values of the PP based composites are higher than that of PP.…”

“…Increases in storage modulus of 10RH-90PP, 20RH-80PP, and 30RH-70PP are 21.7, 29.0, and 33.4 %, respectively, when compared to that of PP at 35 °C. Storage modulus increases due to mechanical limitation posed by increasing filler content embedded in the polymer [25]. The storage modulus values of RH-VS-PP composites are lower than that of 10RH-90PP throughout the whole temperature scale.…”

“…The degradation of RH-PP and RH-VS-PP composites takes place in a twostep degradation process. First step is due to decomposition of agricultural waste filler and the second step is due to PP decomposition [25]. Lignocellulosic materials are thermally decompose between 150°C and 500°C.…”

After agricultural harvests and pruning, billions of tons of agro-wastes are occurred on Earth. Only a small amount of the agro-waste is used as fertilizer and fuel and the rest is not evaluated. The remaining waste can cause air pollution if it is burned in the field. For this reason, this large amount of waste can be used as a reinforcement or filler to produce polymeric composite products. In last decade, the development of natural fiber/polymer composites has gained popularity in many applications such as decking, siding, and automotive indoor parts due to their environment friendly characteristics, low cost, low density etc. In this study, the effective utilization of rice husk (RH) and vine stem (VS) as natural reinforcing fillers in polypropylene (PP) based composites was evaluated. PP matrix composites containing different weight fraction of RH (10%, 20% and 30 %) and hybrid RH-VS-PP matrix composites were manufactured to observe the mechanical (tensile and flexural strengths, and Young's and flexural moduli) and thermal (degradation, melting, and crystallization temperatures etc.) properties of the composites. The RH-PP and RH-VS-PP composites exhibited much better mechanical and thermal properties compared to neat PP. Tensile strength of PP was increased by 10 wt.% of RH addition from 22.3 MPa to 31.0 MPa. The highest flexural strength which is about 55.0 MPa, was obtained by 3RH-7VS-90PP among all composites. Increases in storage modulus of 10RH-90PP, 20RH-80PP, and 30RH-70PP are 21.7, 29.0, and 33.4 %, respectively, when compared to that of PP at 35 °C. When 3wt% VS filled into RH-PP composite, degree of cristallinity (Xc) of the composite was increased approximately 2% as compared to that of 10RH-90PP.

“…Studies have explored routes to convert OP into alternative forms of bioenergy, such as bioethanol [7,8], biodiesel [9,10] and hydrogen production (via catalytic hydrothermal gasification) [11]. Not only has it been trialled as a substrate for anaerobic digestion [12,13], bacterial cellulose production [14] and solid-state fermentation (for xylanase and cellulase production) [15], OP has also been used as fertilizer [16,17], tested as an adsorbent for heavy metal removal [18][19][20] and used as a filler based material for the development of novel polymer composites [21,22]. Thermochemical approaches to process OP have also been studied, which include direct combustion [23][24][25], gasification [26][27][28] and pyrolysis [29][30][31][32] to generate biofuels.…”

Olive pomace is a widely available agro-industrial waste residue in Europe that has the potential to contribute towards a circular, low carbon bio-economy. This study demonstrated, for the first time, the ability to successfully pyrolyse olive pomace with microwaves for the production of bio-char and bio-oil. It was found that the energy requirement needed to pyrolyse up to 80 % of the olive pomace was as low as 3.6 kJ/g and bio-oil yields up to 30 % were produced. Microwave power did not influence the overall yields or the chemical composition of the obtained bio-oils, but did alter the textural properties of the generated bio-chars and their ability to remove methylene blue dye. Optimum processing conditions were found to be within the 3.6 kJ/g energy requirement with a microwave power of 200 W and processing time of 180 sec. These conditions produced a bio-oil fraction containing mainly acetic acid (71.9 %) and a bio-char with a surface area of 392.3 m 2 /g, micropore volume of 0.15 cm 3 /g and a methylene blue removal efficiency of 40 qMB mg/g. The results acquired from this study reveal the superiority of microwave heating in a pyrolysis system and highlight a novel and prospective route for added value recovery from natural waste resources like olive pomace.

“…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.
