“…When clay and biopolymer are combined as bio-composites, compared to when they are used individually, their qualities, such as resilience to low wettability, pH fluctuations, and poor specificity, are significantly improved. According to Xia et al [138], two bacterial strains from wastewater treatment plants (WWTPs) Klebsiella sp. (designated as EPS-K) and Bacillus sp.…”

“…Using phosphoric acid and sodium tripolyphosphate to modify cellulose surface has been investigated to produce biopolymers. The highest levels of adsorption for investigated organic pollutants were at acidic-to-neutral pH, with a capacity of 47.58 mg/g for Rhodamine B and 45.52 mg/g for Amitriptyline [138]. Several investigations used modified cellulose for adsorption as its surface has hydroxyl (OH) groups [139].…”

Algae have the potential to be used as a feedstock for the synthesis of valuable compounds and biofuels. In addition, algal waste can be further transformed into biofuel, biogas, and biochar using different thermochemical processes such as microwave pyrolysis, pyrolysis, torrefaction, and hydrothermal conversion. Due to its high specific surface area, rapid electron transport, and graphitic carbon structure, algal biochar carbonized at high temperatures has shown outstanding performance for applications as CO2 adsorbents, supercapacitors, and persulfate activation. Due to the combination of various functional groups and porous structures, the algae biomass pyrolysis at a moderate temperature produced high-quality biochar that shows high performance in terms of pollutant removal, while low-temperature pyrolysis produces coal fuel from algae via torrefaction. Over time, there have been exponentially more petroleum-based polymers created that have harmful impacts on both humans and the environment. As a result, researchers are becoming more interested in algae-based biopolymers as a potential alternative strategy for establishing a sustainable circular economy globally. The advantages of microalgal biopolymer over other feedstocks are its capacity to compost, which provides greenhouse gas credits, its quick growth ability with flexibility in a variety of settings, and its ability to minimize greenhouse gas emissions.

“…Bioaugmentation is considered more suitable for application in treating heavy metal containing wastewater because the formed stable metal can be easily separated from the wastewater by depositing them at the bottom of the treatment area, producing complete separation with clear differences between phases (water and metal) ( Shahid et al., 2020 ; Titah et al., 2019 ; Xia et al., 2020 ). The treatment of heavy metal contaminated soil may show a reduction in metal toxicity due to the reduction from ionic to nonionic form ( Joutey et al., 2015 ; Wiatrowski et al., 2006 ), but the particle itself remains inside the soil matrix.…”

Interesting properties like renewability, biocompatibility, and biodegradability are present in favorable materials produced by living organisms called biopolymers. They have recently caused some environmental concerns as they have been considered to compete with polymeric materials that are fossil-based. Energy, medical devices, electronics, and food packaging are some of the applications of biobased plastics that are gaining increasing interest. Microbes, agricultural wastes, animals, and plants are some examples of biological sources that can produce biopolymers. Among the promising sources for producing bioplastics are microalgae and cyanobacteria, both of which contain cellulose, carbohydrates (especially starch), proteins, and polyhydroxyalkanoates (PHAs), according to some studies. The potential of microalgal PHAs, polysaccharides, and proteins for the production of bioplastics is summarized in this review. A wide range of applications, including environmental remediation, adsorption, 3D printing, and antioxidants employ Biopolymers. A circular economy approach to microalgal-based bioplastic production is considered in this review to provide insight into current knowledge and future directions.
