“…Polymers, including fossil and bio‐based plastics, are classified as biodegradable if over 60%–70% degrade within 6 months (Awaja et al, 2004). Bio‐based polymers can be produced from plants (Ehman & Area, 2021), and animals (Machineni & Rao Anupoju, 2022). Despite the fact that not all bio‐based plastics are biodegradable,.…”

Environmental pollution is a big challenge that has been faced by humans in contemporary life. In this context, fossil fuel, cement production, and plastic waste pose a direct threat to the environment and biodiversity. One of the prominent solutions is the use of renewable sources, and different organisms to valorize wastes into green energy and bioplastics such as polylactic acid. Chlorella vulgaris, a microalgae, is a promising candidate to resolve these issues due to its ease of cultivation, fast growth, carbon dioxide uptake, and oxygen production during its growth on wastewater along with biofuels, and other productions. Thus, in this article, we focused on the potential of Chlorella vulgaris to be used in wastewater treatment, biohydrogen, biocement, biopolymer, food additives, and preservation, biodiesel which is seen to be the most promising for industrial scale, and related biorefineries with the most recent applications with a brief review of Chlorella and polylactic acid market size to realize the technical/nontechnical reasons behind the cost and obstacles that hinder the industrial production for the mentioned applications. We believe that our findings are important for those who are interested in scientific/financial research about microalgae.

“…There are many cost-effective sustainable environmentally friendly feedstocks or biomasses that can be utilized to produce biobased polymers and composites. − Wood, lignocellulose, starch, sugar, proteins, and plant oils are the most widely used renewable feedstocks in making different biobased polymers for different industrial applications. Plant oils are readily available and cost-effective materials in a large volume. − The chemical structures of all plant oils contain triglycerides of fatty acids of different degrees of unsaturation (i.e., the number of carbon–carbon double bonds). Plant oils can be chemically modified and functionalized into different reactive functional groups, such as hydroxyl, carboxylic acid, epoxy, amines, etc., to increase their utilization in making sustainable products. − Based on the different chemical modifications and functionalizations, plant oils can be used to synthesize many biobased polymers including polyesters, polyurethanes, and polyamides. − …”

“…The obtained soy oil polymer was then reacted with a diethanol amine to synthesize a cold watersoluble hydroxylated soya oil polymer. The obtained polymers were characterized with several techniques including FTIR, elemental analysis, 13 C NMR, and rheology. 49 PCL is a petroleum-based semicrystalline polyester synthesized via the ring-opening polymerization of ε-caprolactone.…”

Creating biobased polymer blends with outstanding properties, nanoscale morphology, shape-memory capability, and biocompatibility is very crucial and requires a fundamental understanding of the phase behavior, macromolecular structure, and biological compatibility of the polymer blends with living cells. It is very critical to understand the complex relationships among the polymer structure, morphology, and performance of multifunctional smart materials under conditions that they are likely to encounter during use, particularly in biomedical applications. Biobased semi-interpenetrating polymer networks of poly(ε-caprolactone) and epoxidized soybean oil with nanoscale morphology have been successfully synthesized via in situ cationic polymerization and compatibilization in a homogeneous solution. Varies analytical and characterization techniques, such as Fourier transform infrared spectroscopy, differential scanning calorimetry, dynamic mechanical analysis, transmission electron microscopy, Xray scattering, cell toxicity, and shape-memory effects (SMEs), have been employed to understand the structure−properties relationship of these smart, biobased nanostructured polymer blends. The synthesized nano blends were nontoxic or biocompatible and supported attachment of human vein endothelial cells, showing their potential use in biomedical applications. The current versatile, low-cost strategy for synthesizing the nanoscale morphology of semi-interpenetrating polymer networks with SMEs and biocompatibility should be widely applicable for polymer systems. This study is also considered as a continuation to our efforts in the area of biobased polymers to develop innovative technologies to transform natural resources into smart multifunctional materials for a wide range of applications, including coatings, adhesives, and medical devices.

“…[13] Thus, laboratories and research centers have been striving to overcome the obstacles and develop biopolymers that are competitive with their respective fossil fuel derivatives. [14] In addition, it is important to emphasize that the development of biopolymers from petrochemical sources will expand with the development of technologies, increasing market demands and overcoming the challenges associated with the transition to the use of plant biomass. [15] The ongoing development of sustainable polymers from biomass requires the constant study of new protocols in catalysis, biocatalysis, materials engineering and polymer science.…”

In recent years, the synthesis of bio‐based polymers and compounds has grown due to greater environmental concerns and the need to develop green and sustainable products as substitutes for fossil derivatives. In this context, lignocellulosic biomass is an important source of raw materials, as it is abundant and low‐cost, in addition to its chemical variety. Thus, chemical catalysis and biocatalysis have been important tools for obtaining these high value‐added compounds. With the aim of detecting the current scenario, as well as the main challenges and opportunities in the production of bio‐based polymers through the valorization of biomass, this work carried out a technological investigation of articles published in the last 10 years, establishing a relationship between the conditions of each production route and its main challenges. The results show a growing number of publications in the last 6 years involving the application of biomass‐derived molecules as monomers to obtain various classes of polymers, where polyesters and polyurethanes have been the most studied. The use of heterogeneous chemical catalysts is still the predominant production strategy, due to the extreme conditions required for production. However, the application of enzymes such as lipases to obtain polyesters and microbial biotransformation to obtain polyhydroxyalkanoates have been emerging as promising strategies within the context of biorefineries. Almost all works are at the proof‐of‐concept stage, where most of the molecules produced have been obtained from synthetic starting materials, demonstrating the need to integrate technologies for obtaining monomers directly from biomass and synthesis protocols for the advent of new processes that are more sustainable and competitive with traditional routes.
