Sustainable lightweight concrete with EPS beads and cork additives: a study on physico-mechanical properties of eco-friendly composites

This study investigates the properties of lightweight concrete composites incorporating expanded polystyrene (EPS) and cork as aggregates, focusing on their effects on density, thermal performance, and mechanical strength. The results show that using EPS and cork significantly reduces the density of the composites, making them suitable for applications where weight reduction is critical, such as in energy-efficient building materials. Additionally, the thermal conductivity of these composites decreases substantially, enhancing their insulating properties. However, the reduction in density is coupled with a significant decrease in compressive strength, with values up to 94% lower than conventional concrete. This limits the use of these lightweight composite materials to non-structural applications or situations where low load-bearing capacity is acceptable. The study also reveals an increase in porosity and capillary water absorption in the composites, which may compromise their durability, particularly in environments with high moisture exposure. In conclusion, lightweight concrete composites incorporating EPS and cork offer considerable advantages in terms of reduced weight and improved thermal insulation. However, for structural applications or where higher mechanical performance is required, adjustments such as the inclusion of reinforcing materials or reducing the lightweight aggregate content may be needed to ensure optimal performance and durability.

New Eco-Friendly Thermal Insulation and Sound Absorption Composite Materials Derived from Waste Black Tea Bags and Date Palm Tree Surface Fibers.

A tremendous amount of waste black tea bags (BTBs) and date palm surface fibers (DPSFs), at the end of their life cycle, end up in landfills, leading to increased pollution and an increase in the negative impact on the environment. Therefore, this study aims to utilize these normally wasted materials efficiently by developing new composite materials for thermal insulation and sound absorption. Five insulation composite boards were developed, two were bound (BTB or DPSF with polyvinyl Acetate resin (PVA)) and three were hybrids (BTB, DPSF, and resin). In addition, the loose raw waste materials (BTB and DPSF) were tested separately with no binder. Thermal conductivity and sound absorption coefficients were determined for all boards. Thermal stability analysis was reported for the components of the tea bag (string, label, and bag) and one of the composite hybrid boards. Mechanical properties of the boards such as flexural strain, flexural stress, and flexural elastic modulus were determined for the bound and hybrid composites. The results showed that the thermal conductivity coefficients for all the hybrid composite sample boards are less than 0.07 at the ambient temperature of 24 °C and they were enhanced as the BTB ratio was reduced in the hybrid composite boards. The noise reduction coefficient for bound and all hybrid composite samples is greater than 0.37. The composite samples are thermally stable up to 291 °C. Most composite samples have a high flexure modulus between 4.3 MPa and 10.5 MPa. The tea bag raw materials and the composite samples have a low moisture content below 2.25%. These output results seem promising and encouraging using such developed sample boards as eco-friendly thermal insulation and sound absorption and competing with the synthetic ones developed from petrochemicals in building insulation. Moreover, returning these waste materials to circulation and producing new eco-friendly composites can reduce the number of landfills, the level of environmental pollution, and the use of synthetic materials made from fossil resources.

Investigating the acoustic performance of sustainable composites utilizing recycled polypropylene and denim shoddy: fabrication, characterization, and theoretical Modelling

Addressing the urgent need for sustainable materials, this study investigates the development of eco-friendly composites using Recycled Polypropylene (RPP) and Denim Shoddy (DS) for sound insulation. Two configurations were fabricated through compression molding: one with only RPP and the other incorporating a DS interlayer, repurposing waste materials such as post-consumer cosmetic containers and denim textile waste. The investigation evaluated the composites' density and sound transmission loss (STL). Theoretical calculations of STL in diffuse fields across various angles assessed the composites' real-world applicability. Incorporating a DS interlayer significantly improved sound insulation properties, with the composite exhibiting a higher density of 916 kg/m³ compared to 891 kg/m³ for Neat RPP. STL measurements showed that the composite achieved approximately average STL of 39.0 dB under normal incidence and 30.8 dB in the diffuse field, compared to 37.7 dB and 30.6 dB for Neat RPP, indicating a positive correlation between increased density and enhanced sound insulation. These findings highlight the potential of using recycled and waste materials for eco-friendly, sound-insulating material. The developed materials show promising applications in highway noise barriers, generator insulation, and office cabin partitions. This research contributes to sustainable materials science by demonstrating innovative sound-insulating composites' environmental and practical benefits.

A cyclic economy and sustainability-driven production are key aspects of the industry. Recycled feedstocks are steadily replacing virgin materials to produce parts and as sustainable additives to develop eco-friendly composites. The reinforcing potential of recycled fine powder glass (FPG) on terephthalate glycol (PETG) is investigated. The performances of six different compounds (with FPG loadings of 2.0, 4.0, 6.0, 8.0, 10.0, and 12.0 wt%) in filament and three-dimensional (3D) specimens form (manufactured with the material extrusion – MEX method) were compared with PETG pure. This research included thermal and rheological analyses, mechanical tests, and morphological and structural investigations. According to these findings, the PETG/RFPG 8.0 wt% composite presented remarkable results in the tensile and flexural (16.3 % and 16.9 % strength increase, respectively) tests, while PETG/RFPG 10.0 wt% had the greatest performance concerning microhardness. Both the dimensional deviation and porosity results show excellent performance in the case of PETG/RFPG 6.0 wt%, by being 67.3 % and 87.1 % improved vs. the PETG pure. These results indicate that RFPG is a promising reinforcement additive for MEX 3D printing that can replace the commonly used inorganic fillers and promote the sustainability of 3D printing.

Fabrication of nanozeolite-Y/chitosan composite based on rice husks for efficient adsorption of methylene blue dye: kinetic and thermodynamic studies

In this work, three solid adsorbents were synthesized, namely, nanozeolite-Y prepared from rice husks ash by a sol-gel method as a green biosource (ZN), chitosan as a cationic biopolymer (CS), and nanozeolite-Y/chitosan composite (CSZ). An eco-friendly composite that consists of chitosan and nanozeolite-Y was used to combine the advantages of nanoparticles with biopolymers two materials to increase the removal % of methylene blue dye. All the synthetized solid adsorbents were investigated using TGA, nitrogen adsorption, SEM, TEM, FTIR, XRD, and zeta potential. The results showed that CSZ particles had a high specific surface area (432.3 m2/g), mesoporosity (with an average pore diameter of 2.59 nm), a smaller TEM particle size (between 28.6 and 60.7 nm), a lot of chemical functional groups, and high thermal stability. CSZ exhibited the maximum adsorption capacity (141.04 mg/g) towards methylene blue. The adsorption nature of methylene blue onto CS and CSZ is endothermic, spontaneous, and a physical adsorption process, while it is exothermic, nonspontaneous, physical adsorption process in the case of ZN, as confirmed by thermodynamic results. Pseudo-second order, Elovich, Dubinin-Radushkevich, Freundlich, Langmuir, Temkin, and adsorption models all fit the MB adsorption well, with correlation coefficients reaching about 0.9997. Nitric acid was found to be the best desorbing agent, with a desorption efficiency of about 99%.

Mechanical behaviour of 3D printed and textile-reinforced eco-friendly composites

3D printing has revolutionised construction with rapid, cost-effective production of complex designs. However, the growing literature focuses on cementitious mixtures with high energy requirements, neglecting eco-friendly alternatives. Additionally, integrating reinforcement is challenging due to complex geometries and anisotropic nature of printed material. This study explores textile materials as reinforcement, offering shaping ease, strength, and design freedom. Two sustainable mixes were formulated: earth-based and lime-based. Composites of 3D-printed earth reinforced with jute fabric and 3D-printed lime reinforced with jute and glass fibre grids were produced. Flexural, compression, and splitting tensile tests were carried out to assess the impact of textile reinforcement. Results showed improved textile-matrix bonding enhanced load distribution and structural integrity. A second mixing, reducing torque value by about six times from its initial unprintable state, is crucial for lime-based mortar printability. Textile reinforcement increased strength by 142.8% and ductility by 1130.3%, demonstrating its effectiveness for sustainable 3D printing construction.

FACILE SYNTHESIS OF ACTIVATED CARBON/ALGINATE/CHITOSAN COMPOSITE BEADS AS RHEMAZOLE BRILLIANT BLUE R ADSORBENT

Developing composite beads composed of chitosan, alginate, and activated carbon for dye removal is essential due to their improved adsorption capabilities and environmental benefits. By utilizing natural resources efficiently for an effective dye removal process, this study developed an activated carbon/alginate/chitosan composite bead as Rhemazole Brilliant Blue R (RBBR) adsorbent. The surface shape of composites exhibits more protrusions, grooves, and asymmetric pores than activated carbon, which could improve dye adsorption capability. FTIR analysis verified that functional groups such as OH, NH, protonated amine, and carboxylate from the constituent polymers were enriched in the activated carbon/alginate/chitosan composite. These groups also function as active sites for adsorbents. It was aligned with the composite beads' Freundlich isotherm model, which shows that heterogeneous or many active sites contribute to adsorption and provide multilayer adsorption. The kinetic model of pseudo-second order fits well with the adsorption process, indicating that chemisorption is the rate-limiting step in RBBR adsorption. The optimum adsorption conditions were at pH 1, with an adsorbent dose of 0.08 g, RBBR dye concentration of 125 mg/L, and a contact time of 60 min. The composite beads also exhibit stability in acidic and basic solutions, with the effectiveness of being reused up to four times, providing a reusable adsorbent with versatility in various water treatment conditions. Hence, synthesizing activated carbon/alginate/chitosan composite beads presents a promising solution for sustainable wastewater treatment based on biodegradable and eco-friendly composite.

Mechanical, durability and microstructural properties of waste-based concrete reinforced with sugarcane fiber

Extensive research has focused on producing sustainable concrete by exploring waste and recycled materials as alternatives to virgin substances. However, waste-based concretes often exhibit inferior durability and mechanical performance compared to traditional concrete. Incorporating reinforcement agents can enhance their performance. This study investigates the use of sugarcane fiber as a reinforcement in waste-based concretes containing fly ash (FA), ground granulated blast furnace slag (GGBS), and recycled concrete fine and coarse aggregates (RFA and RCA). Five dosages of sugarcane fibers (0 %, 1 %, 2 %, 3 %, and 4 % by fine aggregates mass) were examined. Mechanical and durability tests, including compressive strength, flexural strength, water absorption, and chloride ion penetration, were conducted. Scanning electron microscopy and micro-porosity analysis were employed for further assessment. Results show that adding sugarcane fiber enhances the waste-based concrete properties, with 3 % being the optimal dosage. This dosage improves compressive strength by 16 %, flexural strength by 35 %, flexural load bearing capacity by 34 %, energy absorption by 107 %, and toughness index by 6 %, while reducing water absorption by 4 % and chloride ion penetration by 23 %. Further increases in fiber dosage decrease concrete properties. The enhanced behavior is attributed to reduced porosity, refined pore structure, and reduced microcrack propagation. This study underscores the potential of incorporating sugarcane fiber along with waste materials to develop eco-friendly composites, aiming to mitigate carbon dioxide emissions and address environmental concerns.

Mechanical, thermal and biodegradation studies of highly degradable composite films of pectin/guar gum/ polyvinylpyrrolidone with rice crop residues: a future vision of packaging and mulch films

ABSTRACT In the present work, eco-friendly composites were fabricated using pectin/guar gum/ polyvinylpyrrolidone blend as matrix and agriculture waste like rice husk and rice straw as reinforcements. Rice husk and rice straw are treated with an alkali solution and then incorporated into the matrix by solvent casting method. The amount of rice husk/rice straw varied from 5% to 15% of the total polymer content. The interaction between polymers and reinforcements is studied by FTIR which shows the presence of hydrogen bonding among the components. SEM images were used to confirm the homogeneous distribution of rice husk/rice straw in the composite films. Thermogravimetry analysis of the composites and the control (blend) film shows that there is an improvement in thermal degradation stability upon the incorporation of reinforcements. The tensile strength of composites is also augmented when compared with the control film (24.61 MPa) and the composite with 10% rice husk has a maximum (29.41 MPa) tensile strength. The biodegradation study of the composite films is performed by the soil burial method.

Effect of hybridisation on the mechanical and weathering characteristics on jute-arecanut leaf-epoxy composites

ABSTRACT Natural fibres play a crucial role in composites by offering renewable, sustainable, low cost and lightweight alternatives to synthetic fibres, promoting eco-friendly composites. Combination of natural fibres such as jute and areca nut in fabricating hybrid composites with superior properties forms the basis of this study. It was observed that mechanical properties increased with increasing natural fibre content. However, jute composites exhibited better properties (strength and rigidity) than arecanut leaf fibre composites due to their inherent superior properties. Hybridisation of fibres yielded higher properties showing that the combination of jute and areca nut fibres (30 wt % fibre content) is more effective in reinforcing the composites. Weathering characteristics revealed that the water absorption and swelling occurred in composites upon their exposure to external environment, water and chemicals. Moreover, their impact properties also decreased subsequent to weathering. Finite element analysis was carried out on these composites under tensile and flexural loading conditions yielded similar trends with experimental results. Remarkable mechanical properties exhibited due to hybridisation of these composites give them potential to be used in different domains such as automobile interiors, furniture, packaging, etc., with lower cost due to the use of natural fibres.

This study evaluates the thermo-mechanical characteristics of eco-friendly composite made of particulate banana fiber (reinforcement), epoxy resin (matrix) and dragon fruit peel powder (micro filler). The composites were developed using compression moulding technique with 3 factors, 4 variations and Taguchi orthogonal array design (L16). The proposed filler characterization results revealed that the density was 0.97 g/cm3 and combination of C–O, Ca–O, and Ca–Co could improve mechanical strength. Composites with 5 mm fiber length, 40 wt.% fiber weight, and 15 wt.% filler weight have a maximum tensile strength of 25.58 MPa, flexural strength of 44.47 MPa, impact strength 180.33 J/m, and hardness of 82.50 SD. The best composite’s thermal, wear, water and fatigue studies were proposed to suit household applications. The proposed filler improves fiber-resin bonding, which increases thermal stability to 245 °C, wear resistance, decreases water absorption, and results in a fatigue life count of 121000 cycles. Thus, this study concluded that the increasing filler content and decreasing particulate size had an impact on the thermo-mechanical characteristics of banana-reinforced polymeric composites. As a result, an eco-friendly polymeric composite mixer coupler model was developed. Comparative structural and model analyses were performed using ANSYS R17.2. The analysis results confirmed that the proposed composite had higher natural frequencies of 2766.5 Hz and lower deformation values of 0.089293 mm. This proves the proposed eco-friendly composite is a suitable replacement for a synthetic mixer coupler.

In recent years, composite materials have assumed an increasingly dominant role in various industrial sectors, combining lightweight with optimal mechanical properties. In this context, natural fibers are essential for the development of eco-friendly composites, ensuring a balance between performance and sustainability via hybridization. This study provides an experimental and numerical analysis on composite laminates subjected to Low-Velocity Impact (LVI) tests at different energy levels, after an initial mechanical characterization of the materials. Carbon and flax fiber fabrics are chosen as reinforcements embedded in a toughened epoxy resin, as well as in two hybrid configurations; two different stacking sequences are also investigated, with the layers placed at 0°and in a quasi-isotropic (ISO) orientation. Hysteresis curves and energy absorption capability – in terms of specific energy absorption (SEA) – are then discussed and compared to each other, along with cross-shaped damage propagation on fracture surfaces. Numerical finite element (FE) models of tensile, compressive, and LVI tests are designed and solved using LS-DYNA software. In particular, tensile and compressive ones are carried out to calibrate the material cards, which have subsequently been adopted in the LVI models. The results obtained not only show an agreement between the experimental response and the simulated one, but also provide a complete investigation of different materials and orientations under LVI in view of future applications, highlighting the possibility of designing structural components to absorb energy in hybrid composites reinforced with natural fibers.

SEM micrographs revealed the created pores and grown nanotubes within the base material. XPS demonstrated some sites of Oads deficiencies, attributed to the expediting of sensing phenomena. Further, MWCNTs are well functionalized with clay as confirmed via XRD phases such as SiO2 (trigonal), AlKSi3O8 (monoclinic), Al2CaSi2O8 (triclinic) and C2Ca5Si2O13 (monoclinic). Furthermore, BET established the mesoporous nature of CTs15 composite having mean pore size ∼ 3.82 nm, also CO2 gas (200–1000 ppm) was tested at ambient temperature. Moreover, CTs15 composite showed maximum sensor response (S.R.) 5.31 at 1000 ppm of CO2 gas, whereas minimum response/recovery time (Tres./Trec.) 10.87/8.93 s were noticed at 200 ppm while operated at 28℃ (ambient condition). Additionally, LOD assured 217 ppm, which suggests that fabricated sensor is highly sensitive and selective for CO2, and may be used for clean room services. Therefore, this cost effective and eco-friendly composite is suitable for monitoring of CO2 gas for indoor and outdoor environments within a few seconds of Tres. and Trec..

Development and Characterization of Hybrid Particulate-fiber Reinforced Epoxy Composites

Although considered wastes, animal fibers and gastropod shell particles are biodegradable, have low density, high stiffness, considerably high impact absorption capacity and relatively low cost. Therefore, they are finding increasing use as reinforcement materials in polymer composites. This research work studied the tensile, hardness, and wear resistance properties of hybrid snail shell (SSP) and chicken feather barb fibers (CFB) reinforced epoxy composites. The stir cast molding technique was utilized to synthesize the composite samples with 3, 6, 9, 12, 15, and 18 wt.% of the hybrid SSPs/CFB. Compared with the control samples, SSP/CFB hybrid reinforcements enhanced the mechanical properties of the composites. Composites with intermediate weight fraction of 9 wt.% SSP/CFB exhibited overall optimum properties when benchmarked against the control sample with approximately 37, 37, 133, 19, and 59% improvement in wear, hardness, impact, and ultimate tensile strength properties respectively. These enhancements suggested a synergistic effect of the two reinforcement phases. The results presented in this study demonstrated the potential of utilizing bio-derived waste materials for synthesizing eco-friendly composites.

Avocado seed starch utilized in eco-friendly, UV-blocking, and high-barrier polylactic acid (PLA) biocomposites for active food packaging applications

Efficient and effective use of biopolymers, such as starch, has increasingly prompted interest due to the current environmental challenges. However, starch-based composites still show poor ductility along with water and oxygen permeability, which may not meet the requirements for food packaging standards. In this study, modified starch (m-St), isolated from the avocado seed and synthesized with tert-butyl acetoacetate (t-BAA), was embedded into polylactic acid (PLA) to design new eco-friendly composites. The developed biocomposites were found to exhibit high performance with outstanding mechanical properties in conjunction with remarkable light, water vapor, and oxygen blocking features for food packaging applications. PLA/m-St(1:6) 20 wt% composites showed a dramatic increase in elongation at break (EB%) from 3.35 to 27.80 % (about 730 % enhancement) and exhibited remarkable UV-blocking performance from 16.21 to 83.86 % for UVB, relative to pure PLA. Equally importantly, these biocomposites revealed significant improvement in oxygen and water vapor barrier performance by reducing their values from 1331 to 32.9 cc m−2 day−1 (indicating a remarkable reduction of 97.53 %) and 61.9 to 28 g m−2 day−1, respectively. This study can show the great potential of extracting starch from biowaste resources and transforming it into sustainable bio-based composites as a promising solution for food packaging applications.

Eco-friendly composites with specific functional properties

The development of sustainable hydrophobic composite coatings is of high interest for aircraft applications. Currently, the use of natural derived functionalized microparticles as filler to obtain hydrophobic epoxy-based coatings was not deeply investigated. In this scenario, a novel hydrophobic epoxy-based composite including waste hemp microparticles functionalized with silica layer, 3-aminopropyltriethoxysilane, polypropylene-graft-maleic anhydride and silanes (hexadecyltrimethoxysilane and 1H,1H,2H,2H- Perfluorocotyltriethoxysilane) is presented. The resulting coating was casted on typical aeronautical panel, based on carbon-fiber-reinforced polymers, to achieve an improved hydrophobicity and anti-icing property induced by functionalized hemp microparticles.The wettability and anti-icing property were investigated. Compared to unfilled epoxy resin, the obtained composite coating achieved a greater water contact angle of 30° and doubled increase in icing time. Despite the low content (2 wt.%) of hemp particles, DSC analysis displayed a relevant increase in Tg value, confirming an efficient interaction between the epoxy matrix and the functionalized hemp filler. AFM analysis proved how the presence of hemp filler leads to an increase in roughness due to the hierarchical structure formed by the long chains of silane molecules. The combination of silane activity and rough morphology allows the development of hemp composite coatings with enhanced hydrophobicity, anti-icing behavior and thermal stability for aircraft applications.
