“…The findings obtained showed that the highest quality eco-friendly clay bricks were obtained where the solid wastes were added at a concentration between 5% and 10% [28]. The bricks had a density of 1300 to 1800 kg/m 3 , total open porosity between 34% and 49%, water absorption rates between 14% and 28%, and compressive strength of 3.3 to 9.5 MPa. An observation made was that the solid wastes (oat, barley husks, and middlings) incinerated at a temperature of 500 • C, thereby forming a porous structure in the clay body.…”

“…However, Sharda et al [52] highlighted that there was a need to exercise caution and ensure competency in the execution of the fiber reinforcement. Guna et al [3] investigated the use of untreated rice husk (RH) and groundnut shell (GNS) in the preparation of hybrid polypropylene (PP) biocomposites for green building materials. Tests were after that conducted to assess the impact of the percentage of reinforcement on aspects such as sound absorption, flame resistance, thermal insulation, aqueous stability, and mechanical properties.…”

“…However, in regard to the dimension stability, only the three-layered particleboards with a density of 600 kg/cm 3 with resin content at 10% and 12% adhered to established PHILSA standards. Further deductions showed that the optimum three-layered particleboards were developed at 10% resin and a density of 600 kg/cm 3 , whereas single-layered boards were manufactured at 8% resin and a density of 600 kg/cm 3 .…”

“…As the demand for housing increases exponentially, this further strains the construction industry as well as the production of conventional materials such as cement, steel, aluminum, and wood, among others [2]. Guna et al [3] have further argued that the production of the conventional construction materials such as cement also utilizes significant thermal and electrical energy and, as a result, translates into higher building costs.…”

The construction sector, in modern times, is faced by a myriad of challenges primarily due to the increase in the urban population and dwindling natural resources that facilitate the production of construction materials. Furthermore, higher awareness on climate change is forcing companies to rethink their strategies in developing more sustainable construction materials. Diverse types of agro-waste ranging from rice husk ash (RHA), sugarcane bagasse ash (SCBA), and bamboo leaves ash (BLA) among others have been identified as potent solutions in the development of sustainable construction materials. In this review paper, six different construction materials, made using agro-waste products, are examined. The materials include brick/masonry elements, green concrete, insulation materials for buildings, reinforcement materials for buildings, particleboards, and bio-based plastics. The main criterion adopted in selecting the materials regards their popularity and wide-scale use in modern construction applications. Additionally, as this research emphasizes identifying alternative approaches to develop sustainable construction materials, the focus is directed toward mainstream materials whose continued use has an adverse impact on the environment. The findings obtained from the review showed that the use of agro-waste to develop sustainable construction materials was effective, as the developed materials adhered to established building standards. Therefore, this indicates that agro-waste materials have the potential to replace conventional construction materials and hence achieve economic, environmental, and social sustainability in the long run.

This research focuses on the melt processing of biocomposites from a biodegradable polymer blend mixed with hybrid fillers through injection molding technique. An optimized blend ratio (60/40 wt%) poly(butylene succinate‐co‐butylene adipate) (PBSA) and poly(butylene adipate‐co‐terephthalate) (PBAT) demonstrated promising results after blending with a mixture of walnut shell powder (WSP), corn starch and talc in various proportions for use in rigid packaging. The addition of hybrid fillers (i) 10% WSP with 15% talc and (ii) 5% WSP with 5% starch and 15% talc to the polymer blend (60%PBSA/40%PBAT) improved tensile modulus (160% and 162%, respectively) and flexural modulus (147% and 153%, respectively) because of the dispersion of stiffer talc and WSP. Following the addition of fillers, tensile strength of the composites decreased. However, flexural strength improved significantly after filler introduction because of better stress transfer ability. Rheological analysis of filled composites with starch or WSP (25%) depicted similar characteristics of the polymer blend, indicating lower viscosity than hybrid composites. The abundant hydroxyl groups in starch explained the increased water absorption and decreased contact angle compared with other composites. This research's novelty encompasses utilizing low‐cost biomasses with mineral filler into an under‐researched biodegradable polymer blend suitable for single‐use rigid packaging applications.

Polypropylene (PP) is among the most widely used commodity plastics in our everyday life due to its low cost, lightweight, easy processability, and exceptional chemical, thermo-mechanical characteristics. The growing awareness on energy and environmental crisis has driven global efforts for creating a circular economy via developing sustainable and eco-friendly alternatives to traditional plastics produced from fossil fuels for a variety of end-use applications. This review paper presents a brief outline of the emerging biobased PP derived from renewable natural resources, covering its production routes, market analysis and potential utiliza-tions. This contribution also provides a comprehensive review of the PP-based biocomposites produced with diverse green fillers generated from agro-industrial wastes, with particular emphasis on the structural modification, processing techniques, mechanical properties, and practical applications. Furthermore, given that the majority of PP products are currently destined for landfills, research progress on enhancing the degradation of PP and its biocomposites is also presented in light of the environmental concerns. Finally, a brief conclusion with discussions on challenges and future perspectives are provided.
