“…Some big agglomerates of the WIP particles were also observed at 40phr and 60phr WIP, respectively. The weak adhesion results in mechanical properties failure [24,25], which agrees with our experimental results.…”

One of the main issues facing environmental and human health protection is managing and further use of waste tires. Upcycling is a successful recycling strategy that aims to incorporate shredded discarded tires into polymer blends to create products with added value for different uses. Two-roll mill laboratories mixer were used to prepare low-cost, flexible magnetic composites based on an EPDM rubber/ground waste tyres (GRW) blend as a host matrix and waste iron powders (WIP) as dispersed filler. Tensile strength, elongation at break, hardness (shore A) and dynamic mechanical analysis (DMA) were used to evaluate the physico-mechanical properties of the produced blends. The thermal properties of the produced blends were also tested using thermo gravimetric analysis, and the morphology of the blends was observed using a scan electron microscope. The electrical and magnetic properties of the mixtures were also tested. The elemental analysis of the WIP sample showed that it contains about 2.19% SiO2, 76.57% Fe2O3 and 21.24% O2, respectively. Mainly, the investigated mechanical parameters (elongation at break & hardness) increased with increasing the WIP content. A notable decrease of tensile strength upon reaching 50phr WIP is noticed. Enhancement in the thermal stability of EPDM/WIP composites is noticed by increasing WIP content. SEM micrographs detect agglomerates at higher WIP content, resulting in mechanical properties' failure. Moreover, the values ε'& ε' improved by rising WIP content. Also, the electrical conductivity "σ" reaches 10− 4 S/cm for 60 phr WIP. Further, the EPDM/WIP composites may be appropriate for creating soft magnetic materials, which have several applications.

“…Figure 3 illustrates the mechanical properties of LLDPE/WG molds including tensile strength, elongation at break, flexural strength and hardness shore D. From the figure, it can be seen that the tensile strength increase gradually with increasing the waste content (Shafik et al , 2021). The tensile strength increased from 5 MPa for LLDPE filled with commercial gypsum as blank samples to be 11.2 and 13.2 MPa for LLDPE filled with D and S waste, respectively.…”

Purpose The purpose of this study is to utilize two types of gypsum mold wastes from two different factories as novel and economical reinforcing fillers for composites that may be useful for building materials and floors. Two types of gypsum mold wastes from two different factories as raw materials were incorporated into linear low density polyethylene (LLDPE) aiming to get rid of that waste in one hand and obtaining useful economical composites suitable for building materials and floors. Design/methodology/approach Composites were prepared from two types of gypsum mold wastes substituted with different ratios from raw gypsum and LLDPE throughout the melt blending technique. The physico-mechanical and electrical investigations in addition to the morphology of the composites were included. Findings The mechanical results illustrate that substituting commercial gypsum with gypsum mold waste positively affects tensile strength, flexural strength and hardness shore D for the LLDPE composites. The tensile strength increased from 5 MPa for LLDPE filled with commercial gypsum as blank samples to 11.2 and 13.2 MPa for LLDPE filled with D and S waste. Also, electrical properties which include both permittivity ɛ′ and dielectric loss ɛ″ increased with increasing the waste content in the LLDPE matrix. In addition to the electrical conductivity values, σ lies in the order of insulation materials. Consequently, it is possible to produce materials with a gypsum matrix by adding industrial waste, improving the behavior of the traditional gypsum and enabling those composites to be applied in various construction applications as eco-friendly tiles. Originality/value This study aims to prepare eco-friendly composites based on LLDPE and waste gypsum mold to preserve resources for the coming generations, other than lowering the environmental footprint and saving the costs of getting rid of it.

“…The more gaps and voids there are the worse interfacial interaction of WPCs. [ 52–53 ] Moreover, the WF aggregation was more evident in PE matrix at high WF content. [ 54 ] The WF aggregation can seriously deteriorate the mechanical properties of PE/WF composites due to the stress concentration.…”

Here we report a fast functionalization method of PE using ozone oxidization to improve the interfacial adhesion between wood fiber (WF) and oxidized PE (OPE) for preparing wood-plastic composites (WPC). Low density PE at molten state was oxidized (at 220 C for 1 h) to form polar groups on molecular chains and further mixed with different content of eucalyptus WF. The effect of ozone on the molecular structure of PE and the properties of WPCs were investigated by FTIR, XPS, contact angle test, rheological test, SEM and mechanical tests.After ozonization, the hydrophilicity of PE was greatly improved due to the introduction of oxygen-containing groups. As a consequence, the interfacial adhesion between OPE and WF was greatly enhanced as a result of hydrophilicity of OPE. The tensile elongation at break of OPE/WF was maximum increased by 65% comparing to PE/WF composites. It is an effective method to improve hydrophilicity of PE, which will provide a feasible route for recycling and utilizing of recycled polyethylene.
