“…The 50:50 composites showed a tensile strength between 8 and 12 MPa with fairly large variations. These results agree with findings by Bledzki et al (2002) and Abdelaal et al (2012), who found that an increase in wood loading led to decreasing tensile strength in composites without compatibilisers, which could be ascribed to decrease in bonding strength between the wood and the polymer as a result of low adhesion. The tensile strength of pure LDPE was higher than that of composites made with EVOH, which means that the wood filler did not positively impact on the tensile strength, probably due to weak interphase binding through the compatibiliser.…”

“…The polymer matrix of WPCs frequently comprises polyolefins, such as polyethylene (PE), polypropylene (PP), or polyvinyl chloride (PVC) (Abdelaal et al 2012;Sihombing et al 2012) whereas the wood fillers are typically softwood particles that consist of long, uniform fibres with a wellknown chemical composition.…”

“…In addition, there is a broad band between 3300–3400 cm −1 , this can be attributed to the stretching and bending vibrations of hydrogen-bonded surface OH groups of the physisorbed water. This reveals that water molecules are retained in the fabricated CaO and CaCO 3 from the CCS [ 35 ]. The spectra of the 7%, 9%, and 11% CCS-PE plastic bags had characteristic bonds of both CCS and pure PE plastic bags.…”

The addition of calcined waste clamshells (CCS) into polyethylene (PE) plastic bags imparts antibacterial properties due to the presence of CaO. In this study, different proportions of calcined waste clamshells were added to PE to explore its bacteriostatic effects. The PE plastic bags with 9% and 11% of CCS exhibited antibacterial efficacy. Further, total aerobic viable count (TVC) values for raw fish fillet packaging in 9% and 11% CCS-PE plastic bags for five days were similar to the 0% CCS-PE plastic bag group after three days of incubation. In addition, the CCS-PE plastic bag demonstrated stability against solvents when examined using the metal migration test under heptane, ethanol, and acetic acid treatments. The results revealed that the CCS-PE bag retains its CaO bacteriostatic efficacy and that the addition of CCS powder to PE prolongs the shelf life of raw fish fillets, as well as mitigating safety concerns from metal leakage.

“…The good surface finish enabled by these composites has also fostered, for instance, the production of parts applied in certain dynamical systems of the automobile that require a specific tribological behavior. Other procedures such as surface modification of the fibres are also frequently applied [14,23,[34][35][36][37].…”

In the last decades the studies on thermoplastic composites reinforced with natural fibres have been mostly focused on vegetable lignocellulosic or cellulosic fibres. These materials provide eco-sustainable solutions for a large range of applications and have been actually adopted by multiple industries. The interest on fibres of animal origin is more recent and research on composites reinforced with these fibres predominantly composed of keratin, such as wool, feathers or silk, is increasing in virtue of some advantageous properties that may overcome some of the intrinsic limitations from vegetable fibres. The combined use of vegetable and animal fibres in composites appropriate for melt blending processing is at early stages of research. After chemical treatments, the fibres of animal origin have been mostly applied as binders between vegetable fibres and polymers, not as main constituents of these composites. The use of both types of fibres simultaneously in composites of thermoplastic matrices is the subject of the present study wherein the fibres of animal origin (wool) are different kinds of residues from a textile industry and the fibres of vegetable origin (wood) are residues from carpentry activities. The chemical composition, the macro and microstructure of the fibres is analyzed, as well as that of composites that combine non-biodegradable and biodegradable polymers with diverse ratios of fibres in different conditions (wool as cards, yarns and felt cloths; wood as sawdust). The addition of coupling agents to enhance the compatibility between wool, wood and different polymers is also analysed.
