“…The permeability values of RH-filled films increased further to higher amount in the same manner, by the increase in RH loading. The similar behaviour have also been reported by George et al (2006) in the LDPE/rice bran composite films where oxygen barrier was deteriorated by adding rice bran. …”

“…The tensile strengths of the composites of 3 and 5 wt% RH are 9.9 and 8.1 MPa, respectively, at dry conditions. This decrease in the tensile strength may probably be due to incompatibility of RH with thermoplastic matrix that leads to poor interfacial adhesion, which would have caused discontinuity in the matrix material, resulting in reduction in tensile strength (George et al 2006). These findings further support the findings of Bendahou et al (2008).…”

The past few years have witnessed a renewed interest in developing new ecofriendly materials, sparked mostly by the nonbiodegradability of most of the polymeric materials. In this context, incorporation of biofibres as load-bearing constituents in polymeric composites is a highly attractive research line for the development of ecofriendly composites. An experimental study, with the overall aim of making environmentally compatible packaging film, was conducted to investigate the influence of rice husk (RH) loading on morphological, tensile, oxygen barrier and biodegradation properties of low-density polyethylene (LDPE)-based extrusion blown films. Various compositions were prepared with varying contents of RH and the properties were correlated with the loading of RH. Morphological observations revealed that there were micro-voids at interface and the RH particles start agglomerating beyond 5 wt%. The tensile, tear and oxygen barrier properties decreased as the loading of RH increased. Soil burial tests revealed that the composite films are biodegradable and RH loading has significant impact on rate of biodegradation.

“…Most natural fillers have a structure which promotes increased water absorption, which changes mechanical properties of polymer. A similar trend was reported in other studies investigating the effect of various natural fillers, such as rice bran, corn and potato starch, on the mechanical properties of polymer compositions [22,23]. Table 4 illustrates the relationship between tensile stress at yield of the filled specimens and filler contents and grain size.…”

In recent decades, standard polymer blends for different applications have been more and more often replaced by blends containing raw materials. The use of natural materials as filler in thermoplastics brings both economic and environmental benefits. The use of a given vegetable filler depends on the geographic location and natural occurrence of the vegetables in a given geographic region. In Poland, for instance, the pumpkin is one of such vegetables. They are used for producing oil which is pressed from pumpkin seeds. Pumpkin seeds are then collected, dried and purified to produce waste material in hull form. Particles of ground pumpkin seed hulls with varying sizes and weight-in-weight concentration ranging from 0% to 20% relative to the matrix are used as filler in low-density polyethylene. Pumpkin seed hulls are ground and sieved. Four fractions of hulls with different particle sizes are produced: <0.2 mm, 0.2-0.4 mm, 0.4-0.6 mm, 0.6-0.8 mm. The paper reports the results of investigation of the mechanical properties, i.e., strength properties determined by static tensile testing and hardness measurement, of injection molds produced at constant processing parameters. In addition, the cross sections of the obtained products are subjected to microscopic examination. Relationships are determined between tensile modulus, maximum tensile stress, tensile stress at yield, maximum tensile strain, tensile strain at yield as well as Shore hardness and weigh-in-weight concentration of the powdered natural filler and its grain sizes. Finally, relevant conclusions are drawn.

“…Potential benefits of co-processing include the volume reduction of waste, the recovery of various chemicals, and the replacement of fossil fuels [16]. In fact, a synergistic effect in terms of enhanced liquid yields and mechanistic explanations therefore has recently been reported [17][18][19][20][21][22][23][24][25].…”

Thermal degradation behavior of mixtures of rice bran (RB) and high density polyethylene (HDPE) was investigated by thermo-gravimetric analyses (TGA) under dynamic conditions in nitrogen atmosphere and was compared with that of individual materials. Experiments were carried out in the range of ambient temperature to 900 o C at two heating rates (5 and 20 o C per minute). Kinetic analysis indicated that activation energy for pyrolysis of RB, HDPE and those for RB-HDPE mixtures varied with rate of heating as well as with the three temperature ranges. This variation has been explained on the materials' decomposition behavior. Maximum difference between experimental and theoretical mass loss (∆m) was 26% at 475 o C and 34% at 489 o C at the heating rates of 5 and 20 o C per minute, respectively. These maxima indicate stronger interactions at corresponding temperature between RB and HDPE during copyrolysis. Reduction in activation energy for pyrolysis, lower temperatures at which rate of decomposition is highest, and negligible quantity of the residue suggest a synergism between thermal degradation of RB and HDPE.
