Straw, the primary agricultural waste, constitutes approximately 20% of the total biomass in the EU. Only a small fraction of the material is applied in various products, e.g., animal bedding, mulch, building, and composite materials, while a significantly larger portion is often burned in the field. This practice, while prohibited for several reasons, including the increased risk of fire and the release of carbon dioxide contributing to global warming, is still prevalent. Given the increasingly evident effects of climate change, EU legislation aims to reduce greenhouse gas emissions as much as possible. One of the strategies includes applying the cascade principle in the circular economy. This principle aims to use the entire raw material, in this case, cereal crops, such that the products with the highest added value, like cellulose fibers from cereal straw, are extracted first. The vast potential for utilizing lignocellulosic agro-waste sustainably arises from its status as the most abundant organic compound on Earth. Its significant presence, renewability, and biodegradability make it a desirable source for producing materials in numerous industries. This study examines the potential of wheat fibers, isolated from the straw of two distinct cultivars (Srpanjka represents an old variety, and Kraljica represents the new variety) primarily for application in technical textiles. The following testing methods were applied: determination of wheat fibers and residues yield, fibers tensile properties, length, moisture content/regain, density, morphology, and Fourier transform infrared (FTIR) spectroscopy. The yield of isolated fibers relies on the wheat variety and the climatic conditions affecting plant growth, resulting in fiber yields from 10.91% to 15.34%. Fourier transform infrared (FTIR) analysis indicates reduced peak intensity, which is related to hemicellulose and lignin content, suggesting their improved deposition following the process of chemical maceration. Wheat fiber quality was found to be comparable to cotton fibers regarding its density. However, they showed a significant difference in higher moisture regain (9.72–11.40%). The vast majority of the scientific papers related to wheat fibers did not indicate the length of the individual fibers obtained by chemical maceration nor their strength. Therefore, this paper indicated that both varieties demonstrated sufficient fiber tenacity (greater than 10 cN/tex) and fiber length (2–3 cm), stressing the spinning potential of these fibers into yarns and extending their use to the apparel industry. Moreover, our research underscores the feasibility of adhering to the zero-waste principle. A high percentage of solid waste remaining after fiber extraction (25.3–39.5%) was successfully used for biofuel production, thus closing the loop in the circular economy.

“…For the water resistance of biomass composites, in general, the biomass composites prepared from soybean straw powder with large particle size have better water resistance, Figure 7e. The water absorption of composites is influenced by several factors, not only related to the type and relative amount of resin matrix and plant fibers used but also to the particle size and surface roughness of the fibers and also depends on the interfacial bond between the fibers and the resin [23].…”

The biomass composites were prepared by hot molding with a pressure of 10 MPa, a temperature of 125 °C, a time of 15 minutes using soybean straw powder, poplar wood fibers, and soy protein as raw materials. The effects of different straw species, the ratio of soybean straw powder to poplar wood fibers, the particle size of soybean straw powder, and the theoretical density on the performance of biomass composites were investigated. The experimental results show that under the condition that the ratio of soybean straw powder and poplar wood fibers is 1 : 1, 20 mesh to 40 mesh soybean straw powder and 20 mesh to 60 mesh wood fibers are selected to copolymerize and strengthen the soy protein biomass composites when the theoretical density is 0.80 g/cm3, the actual density of the biomass composites is 0.90 g/cm3, the tensile strength was up to 22.04 MPa, and the bending strength was up to 44.92 MPa. Biomass composites have good water resistance while obtaining excellent mechanical properties. The above figures not only meet the relevant technical requirements of automotive interior parts but also enable the lightweight design of automobiles and the sustainable development concept of green, low carbon, and environmental protection.

“…Various types of industrial waste materials, such as fly ash, slag, or kaolin sediments, may serve as a source of aluminosilicate material in geopolymer production and, therefore, provide a cement replacement, leading to a reduction in carbon dioxide emissions [4]. Incorporating agricultural residues into building materials has recently attracted more attention, resulting in the development of new composite materials with specific properties and reducing environmental pollution [5][6][7][8][9][10][11]. For the effective application 2 of 14 of biomass residues in composite materials, their surface pre-treatment is needed to remove components covering the surface of biomass, such as waxes, lignin, and hemicellulose, which reduce the compatibility or bonding strength with a matrix [8,[12][13][14][15].…”

The development of new composite materials with specific properties and reduced environmental pollution can be achieved by the incorporation of agricultural residues, whose morphology is strongly affected by their variety and growing conditions. Herein, the functional properties of a cement-free geopolymer composite reinforced with straw from two wheat varieties (Ada and Malibu) were investigated through different straw pre-treatment methods and their surface modification with silane coupling agents. The characterization of the wheat surface and the geopolymer composites involved SEM-EDS, TGA, FTIR, and gas physisorption analysis methods supplemented with mechanical strength and moisture ingress measurements. Mild (23 °C) and severe (100 °C) physical pre-treatment methods with chemical soaking in 7.3 M isopropanol solution were applied on wheat straw. Tetraethoxysilane (TEOS) with octadecylamine was employed for chemical surface modification. The set of geopolymer compositions was prepared with untreated, pre-treated, and modified straws. The results revealed the hot pre-treatment method caused a higher degradation of siliceous layers of straw, especially in the Ada variety. The modification with TEOS resulted in irregular silane coating formation regardless of the wheat variety and pre-treatment method. Despite good interfacial bonding of the modified straw with the geopolymer matrix, the mechanical strength of the composites was reduced, although the resistance to water ingress slightly increased. Comparing both varieties, Ada wheat showed better performance than Malibu.
