“…33 A frequent driver behind the adoption of biomass-based materials are claims of source renewability. 13,14,35,36 As previously emphasized, simply extracting from an organic source is not enough to claim meaningful renewability, and these claims should be made only once the rate and impact of extraction are fully understood. Nonrenewable sources used as energy sources or additives in composites should be quantified and considered as part of the material system.…”

“…Recently, a significant amount of research has been conducted on the use of biomass as a rapidly renewable material source. , Material systems using biomass are frequently cited as being inherently renewable, , but meaningful renewability requires that the extracted source be replenished by nonhuman processes at a rate equal to or greater than the rate of extraction. For example, hardwood lumber in an unmanaged forest system may be renewable at a low rate of extraction but would require more intensive regulations to maintain renewability at higher rates of extraction.…”

Engineered materials are ubiquitous throughout society and are critical to the development of modern technology, yet many current material systems are inexorably tied to widespread deterioration of ecological processes. Next-generation material systems can address goals of environmental sustainability by providing alternatives to fossil fuel-based materials and by reducing destructive extraction processes, energy costs, and accumulation of solid waste. However, development of sustainable materials faces several key challenges including investigation, processing, and architecting of new feedstocks that are often relatively mechanically weak, complex, and difficult to characterize or standardize. In this review paper, we outline a framework for examining sustainability in material systems and discuss how recent developments in modeling, machine learning, and other computational tools can aid the discovery of novel sustainable materials. We consider these through the lens of materiomics, an approach that considers material systems holistically by incorporating perspectives of all relevant scales, beginning with first-principles approaches and extending through the macroscale to consider sustainable material design from the bottom-up. We follow with an examination of how computational methods are currently applied to select examples of sustainable material development, with particular emphasis on bioinspired and biobased materials, and conclude with perspectives on opportunities and open challenges.

“…PHAs are an essential source of packaging material because of qualities including thermoplasticity, hydrophobicity, insulation, and vapor barrier. PHA-derived jars, disposable cups, trays, containers, and foam-based packaging utensils are already available in the food industry (Rekhi et al, 2022 ). PHAs have various medical utilizations such as drug carrier, tissue engineering, heart valves, surgical sutures, medical implants, artificial skin, artificial organ reconstruction, chemotherapeutics, antibacterial, anti-cancer agents, memory boosters, and biocontrol agents in aquaculture.…”

Petroleum-derived plastics are linked to a variety of growing environmental issues throughout their lifecycle, including emission of greenhouse gases, accumulation in terrestrial and marine habitats, pollution, among others. There has been a lot of attention over the last decade in industrial and research communities in developing and producing eco-friendly polymers to deal with the current environmental issues. Bioplastics preferably are a fast-developing family of polymeric substances that are frequently promoted as substitutes to petroleum-derived plastics . Polyhydroxyalkanoates (PHAs) have a number of appealing properties that make PHAs a feasible source material for bioplastics, either as a direct replacement of petroleum-derived plastics or as a blend with elements derived from natural origin, fabricated biodegradable polymers, and/or non-biodegradable polymers. Among the most promising PHAs, polyhydroxybutyrates (PHBs) are the most well-known and have a significant potential to replace traditional plastics. These biodegradable plastics decompose faster after decomposing into carbon dioxide, water, and inorganic chemicals. Bioplastics have been extensively utilized in several sectors such as food-processing industry, medical, agriculture, automobile industry, etc. However, it is also associated with disadvantages like high cost, uneconomic feasibility, brittleness, and hydrophilic nature. A variety of tactics have been explored to improve the qualities of bioplastics, with the most prevalent being the development of gas and water barrier properties. The prime objective of this study is to review the current knowledge on PHAs and provide a brief introduction to PHAs, which have drawn attention as a possible potential alternative to conventional plastics due to their biological origin, biocompatibility, and biodegradability, thereby reducing the negative impact of microplastics in the environment. This review may help trigger further scientific interest to thoroughly research on PHAs as a sustainable option to greener bioplastics.

“…Using lignocellulosic materials, especially from the forestry sector, contributes to the reduction of recourse to petrochemical resources. [4][5][6] Wood is an abundant lignocellulosic material consisting of three main constituents, namely cellulose, hemicellulose, and lignin, arranged together in a sophisticated way, which give high strength and a rigid cell wall. 7 Therefore, contrary to plastic materials in native condition, wood does not easily solubilize or melt through conventional extrusion or molding processes.…”
