“…Based on the tensile strength, Young modulus and strain-at-break data, it can be concluded that the use of compatibilizer led to improvement in the interfacial adhesion between WF and polymer. The improvement in mechanical properties of the composites with the use of compatibilizer were also reported by previous studies [27][28][29][30][31][32][33][34]. MAPP and MAPE provide a chemical bonding between the hydrophilic WF and hydrophobic polymer [23,32,34].…”

“…The presence of polar and non-polar groups in the structure of coupling agents or compatibilizers provides the bonding between polymer and wood. This bond enhances the compatibility and the interfacial adhesion between polymer and wood, and leads to the improvement of mechanical properties of WPC [27][28][29][30][31][32][33][34].…”

“…WPC combines the availability and aesthetic properties of wood, and moulding capability and high environmental resistance of plastics, such as against water [10,[18][19][20][21][22][23]. Moulding capability of plastics enhances the application areas of WPC at different shape profiles ranging from exterior and interior construction materials such as pallets, sidings, decks, and fences to automotive components such as seat backs and front/rear door linens [11,[24][25][26][27][28].…”

“…There are few studies related to the mechanical properties of WPC from recycled polymer and wood. Bütün et al [27] indicated the possibility of WPC production with recovered wood particles obtained from fibreboard (MDF) disintegration technique. Chaharmali et al [35] produced WPC panels and particleboard with recycled HDPE bottles.…”

In this study, Wood Plastic Composites (WPCs) were produced from post-consumer bulky wastes of recycled plastic and wood in order to minimize waste, decrease environmental effects of plastics, reserve natural resources, and support circular economy for sustainable production and consumption. Five different types of polypropylene (PP) or polyethylene (PE) based recycled plastics and wood obtained from urban household bulky wastes were used in the production of recycled WPC composites, r-WPCs. Virgin WPC (v-WPC) and r-WPC compounds were prepared with wood flour (WF) and maleic anhydride grafted compatibilizer (MAPP or MAPE) to evaluate the effect of recycled polymer type and compatibilizer on the mechanical properties. It was found that tensile strength properties of r-WPCs produced from recycled PP (r-PP) were higher than that of the r-WPCs produced from mixed polyolefins and recycled PE. r-WPCs containing anti-oxidants, UV stabilizers, and compatibilizer with different WF compositions were produced from only recycled garden fraction PP (PPFGF) to determine the optimum composition and processing temperature for pilot scale manufacturing of r-WPCs. Based on tensile, impact, flexural, and water sorption properties of r-WPC compounds with different formulations, the optimum conditions of r-WPC compounds for industrial manufacturing process were determined. Surface morphology of fractured surfaces as well as tensile, flexural and density results of r-WPC compounds revealed the enhancement effect of MAPP on interfacial adhesion in r-WPCs. r-WPC products (crates and table/chair legs) based on bulky wastes were produced using an injection molding process at industrial scale by using 30 wt% WF-filled r-WPC compound. This study demonstrated that r-WPC compounds from recycled bulky plastic and wood wastes can be used as a potential raw material in plastic as well as WPC industry, contributing to circular economy.

“…Therefore, additional preparation and treatment of particles and fibres surfaces are necessary. Most of the researchers used maleic anhydride grafted polypropylene (Yang, Qiao, & Wolcott, 2010;Zhu, Cao, Wang, Liu, & Zhao, 2014;Bütün, Sauerbier, Militz, & Mai, 2019) as compatibilizer in polypropylene/wood-based composites. Their studies reported that maleic anhydride can improve the mechanical performance of composites as interfacial adhesion between wood aggregate and polymer matrix is improved.…”

For the production of traditional building materials, excavated natural resources are used. The production process of such materials requires high-energy demands, wherefore, high amounts of CO2 gases, which have a great impact on climate change, are emitted. Only a small part of such materials is effectively recycled and reused. Generally, they are transported to landfills, which rapidly expand and may pollute the soil, groundwater and air. Currently, a great attention is paid to the production of novel building materials. The aim is to use as less excavated materials as possible and replace them by natural renewable resources. Therefore, the recycling and utilisation at the end of life cycle of such materials would be easier and generation of waste would reduce. This way, the efforts of switching to circular economy are being put. One of the approaches -wider application of vegetable-based raw materials (cultivated and uncultivated agricultural plants). The usage of fibre hemp shives (HS) as an aggregate and corn stach (CS) as a binding material allows development of biocomposite boards (WPCs) which could contribute to the solution of the before mentioned problems. Bio-sourced materials combined with a polymer matrix offer an interesting alternative to traditional building materials. To contribute to their wider acceptance and application, an investigation into the use of wood-polymer composite boards is presented. In this study, biocomposite boards for the building industry are reported. WPCa are fabricated using a dry incorporation method of corn starch and HS treatment with water at 100 °C. The amount of CS and the size of the HS fraction are evaluated by means of compressive, bending and tensile strength, as well as microstructure. The results show that the rational amount of CS, independently on HS fraction, is 10 wt.%. The obtained WPCs have compressive stress at 10% of deformation in the range of (2.4-3.0) MPa, bending of (4.4-6.3) MPa and tensile strength of (0.23-0.45) MPa. Additionally, the microstructural analysis shows that 10 wt.% of CS forms a sufficient amount of contact zones that strengthen the final product. The obtained average density (~319-408 kg/m 3 ) indicate that, according to European normative document EN 316, WPCs can be classified as softboards and used as self-bearing structural material for building industry. Based on the requirements, WPCs can be applied in dry and humid conditions for the internal and external uses without loading (EN 622-4, section 4.2) or as load-bearing boards in dry and humid conditions for instantaneous or short-term load duration (EN 622-4, section 4.3).
