From the packaging that safeguards our groceries to the components in our electronic devices, the omnipresence of polyethylene-based plastics underscores their indispensability. However, this pervasive reliance on plastics has ushered in a host of challenges, chief among them being the degradation of these materials. The degradation of plastics represents a multifaceted dilemma, exacerbated by the sheer scale of their consumption. Conventional degradation methods, including physical, chemical, landfilling, and pyrolysis, are intricate processes fraught with complexities. These methods, while attempting to mitigate the environmental burden posed by plastics, often introduce new challenges, including toxicity to the air, water, and land. Moreover, the consequences of plastic accumulation reverberate throughout ecosystems, with wildlife ingesting plastics and water systems clogged by their persistent presence. In response to these pressing environmental concerns, the pursuit of biodegradation solutions has emerged as an imperative. Bacteria and fungi, nature’s recyclers, offer promising avenues for the degradation of plastics. The biodegradation of plastics by microbial organisms represents a burgeoning field of research, with ongoing efforts aimed at elucidating the mechanisms underlying this process. The focal point of this study revolves around the biodegradation of polyethylene fragments, spearheaded by the microbial prowess of Pseudomonas and Aspergillus species. To simulate real-world conditions, low-density polyethylene fragments are meticulously prepared, sterilized, and then introduced into cultures teeming with these microbial agents. Over a span of 30 days, at a temperature conducive to microbial activity, the fate of these polyethylene fragments is meticulously monitored. Quantifying the biodegradation process necessitates a multifaceted approach, incorporating various analytical techniques. Viable cell counts, conducted using sophisticated colony counters, provide insights into microbial proliferation. Gas chromatography–mass spectrometry analysis enables the identification of degradation by-products, shedding light on the intricate biochemical pathways at play. Moreover, morphological changes in the polyethylene fragments are scrutinized using compound microscopy and scanning electron microscopy, offering visual cues to the degradation process. The determination of fragment weight loss serves as a tangible marker of biodegradation efficacy, offering quantitative data to complement qualitative observations. In tandem with this study, parallel investigations delve into additional facets of plastic biodegradation. Fourier transform infrared (FTIR) spectroscopy, a powerful analytical tool, unveils chemical transformations occurring during the degradation process.

Date palm tree has been a renowned source of lignocellulosic fibers/fillers in the development of polymeric composites. However, date palm leaves (DPL) have not been explored in woven form; therefore, in the current research endeavor, DPL have been weaved into woven mat form to investigate the DPL potential to be used as reinforcement in composite laminates. The DPL was modified with chitosan solution to enhance their thermal stability. The composite laminates were developed using direct compression molding using film stacking method. The influence of DPL reinforcement on mechanical, thermal, flammability, and dynamic mechanical behavior of the composites has been investigated and is reported. The tensile strength was found to decrease for PP-DP composites, while tensile modulus was found to increase, while, for chitosan-treated DPL reinforced composite (PP-DP-Cs), a slight improvement of about 0.81% in tensile strength was recorded, and tensile modulus was improved by 42.20%.

The present study also aims to investigate the mechanical, wear, and thermal stability properties of bio-oil toughened polyester matrix reinforced under palm kernel fiber and chitosan biopolymer. Furthermore, for understanding the overall performance of the composite, and the durability of the material over a period of time, the present study examined the composite strength after the aging process, which is treating under varying atmospheric conditions, and it brings a novelty to this study. The chitosan is rich in amine groups, which promote the mechanical strength of the material, and it is bio-extracted from sea urchin species using alkali and acid treatment. Further, for promoting toughness and stiffness properties to the composite, the cardanol oil is blended with resin matrix. Finally, using those raw materials, the composite material is prepared under the hand layup method. The result of the study demonstrated that the addition of chitosan biopolymer of 3 vol.%, fiber of 40 vol.%, and cardanol oil of 20 vol.% on the composite PC5 shows better mechanical, wear, and thermal stability behavior when compared to aged composite material. The study findings concluded that the tensile and flexural strength of aged composite PC5 is 20% reduced strength when compared to unaged composite material. Further, the increase chitosan of 5 vol.% in composite (PC6) exhibited a COF of 0.45 and a specific wear rate of 0.005 mm³/Nm, representing reductions of 43.75% and 85.71%, respectively, compared to PC0. The thermogravimetric analysis (TGA) further highlighted the thermal stability improvements, with chitosan-reinforced composites exhibiting the highest resistance to thermal degradation. PC6 retained 80% of its weight at 500 °C compared to only 20% for the plain resin. The fatigue properties also followed a similar trend, with PC5 demonstrating fatigue lives of 20 × 10³ cycles at 25% UTS, 18 × 10³ cycles at 50% UTS, and 16 × 10³ cycles at 75% UTS, indicating significant improvements over the plain resin. Thus, the overall study of the composite shows that reinforcement of kernel fiber, chitosan, and cardanol oil into the composite shows superior mechanical, wear resistance, and thermal stability properties; however, the composite under aging drops in strength property, and it is considerable. Due to such superior strength, wear resistance, and corrosive resistance even under the aging process, the biocomposite is applied in housing kitchens, washtubs, turbine blades, windmill sectors, interior door panels automotive, aviation sector, etc.</p>","PeriodicalId":488,"journal":{"name":"Biomass Conversion and Biorefinery","volume":"172 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142180150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Examples of these technologies are hydrothermal carbonisation, liquefaction, and gasification. Different kinds of wet biomass are converted using hydrothermal technology into products with added value including syngas, bio-oil, and hydrochar. Because the biomass is treated wet in hot-compressed water as slurry, this method has been found to be particularly suitable for high-moisture aquatic biomass, such as macro- and microalgae.
