“…Both plant and animalbased biomaterials have displayed great affinity towards organic and inorganic pollutants. For instance, RE% of over 90% have been reported for dye pollutants (Methylene blue, Congo red) [51], over 400 mg/g for heavy metals (Cu, Cr, Pb, Ni, Cd) [61,105], and even adsorption capacities of 99% have been reported for industrial wastewater effluents [106].…”

There is substantial concern about critical environmental problems related to waste in production sectors such as textile, construction, and packaging. The materials ascribed to the sector’s unsustainability are primarily fabrics, plastic, and hazardous solvents, making developing new biobased materials imperative. As such, various strategies have been investigated to convert and recycle waste and give them commercial value via the manufacture of biobased materials. This review discusses the various types of raw materials as sources to develop new biobased materials that could promote the transition toward sustainability. According to the literature, the functional qualities of biobased materials are comparable to those of synthetic materials. Raw material sources such as biomass, derived from plant and animal-based waste, are attractive due to their low cost, abundance, and biodegradability. The manufacture of biomaterials, as well as their characterization and performance, are also discussed. Further, this review will offer a comprehensive view of the potential applicability and current commercial applications of the developed biobased materials in relevant areas such as packaging, construction, textile, and wastewater remediation. This could be a potential field of research to address the environmental challenges posed by the continuous growth of the global population.

Petrochemical costs, limited fossil fuel reserves, and concerns about greenhouse gas emissions have raised interest in developing renewable approaches for synthesizing biobased polyurethanes. This study aims to solve these problems by making nanocrystalline hydroxyapatite (HA) reinforcement from waste chicken eggshells and adding it to polyurethane synthesis through in situ polymerization. The novelty of the research lies in the utilization of HA as a reinforcement material and renewable resources for polyurethane production. The results confirm that HA was successfully added to the polyurethane backbone. Fourier transform infrared (FTIR) analysis confirmed that the NCO groups were changed to urethane linkages. TGA examination demonstrated that the samples exhibited thermal stability up to 457 °C with a mass loss of 61%, indicating enhanced thermal stability. DMA measurements showed improved mechanical properties of the synthesized polyurethanes, with storage modulus (E′), complex modulus (E*), and compliance complex (D*) values of 0.177, 22.522, and 0.660 MPa–1, respectively. SEM analysis confirmed the homogeneous surface and well-dispersed HA reinforcement. Swelling characteristics revealed an optimum absorption of 30% H2O, 35% CH3OH, and 45% CCl4. Polyurethane composites exhibited significant chemical resistance and hydrolytic stability in acidic and basic media. Additionally, the composites demonstrated efficient adsorption of methyl orange from wastewater, with the PUHCI series achieving a maximum adsorption capacity of 85.50 mg/g under optimal conditions of 0.030 g/mL dose, 45 °C temperature, 2.5 h contact time, and pH 6.0..

To improve the performance of ethanol production from food waste, a consolidation process involving both the addition of surfactant and cell immobilization was investigated. Results showed that the optimum glucose concentration was 200 g/L for ethanol fermentation using Saccharomyces cerevisiae as inoculum. With the addition of 0.5% Tween 80, the ethanol production was improved from 68.1 to 79.8 g/L, which was attributed to the increased mass transfer of cells provoked by Tween 80. In a cell-immobilized system, wheat straw was used as the matrix to carry the cells. A high ethanol production of 87.8 g/L was obtained with the sequential fermentation mode due to the high cell density on the cell carrier. The results of a mass balance calculation revealed that the ethanol production of food waste achieved 340.4 kg/t (on a dry basis), which provided an insight that food waste was a suitable substrate for ethanol production. The main cost was spent on energy consumption in the processes of food waste sterilization, hydrolysis, fermentation, and ethanol distillation, and measures for reducing the energy were suggested to improve the economic performance of ethanol production.
