This work aims at the characterization and performance analysis of biodegradable sheets made by using natural ingredients to reduce the dependency on synthetic plastics and thus culminate in plastic pollution. The multifunctional properties of the prepared sheet from raw jute were quite decent; the tensile strength of the biodegradable sheet was increased to around 22 ​MPa, whereas the tensile strength of the synthetic plastic sheet is around 15 ​MPa. Moreover, the elongation rate also decreased to around 53%. The biodegradability test ascertained the prepared sheet's degradability; the biodegradability rate of the prepared sheet was higher than the synthetic plastic sheet, and also had a nice color appearance due to the colorization with natural dye (turmeric). The outstanding physico-mechanical qualities, satisfactory color durability, and biodegradability of the prepared colored sheet obtained from raw jute could make it an attractive choice for the synthetic plastic sheet and the engendered green polymer nanocomposites. It was the first, and unique endeavor to produce natural colorful biodegradable sheets by utilizing natural ingredients: nanocellulose from raw jute and natural coloring material. It could be recommended that the acquired biodegradables have a prosperous future as a replacement for non-biodegradable traditional plastics.</p></div>","PeriodicalId":296,"journal":{"name":"Current Research in Green and Sustainable Chemistry","volume":"6 ","pages":"Article 100351"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"2699607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, biodegradable plastics manufactured from natural ingredients are showing hope. The current work deals with developing and characterising starch-based bio-plastic where white vinegar and glycerol have been used as matrix materials and tea has been used as filler material. The developed bio-plastic samples were characterized by soil biodegradation test, Mechanical test, Fourier Transformed Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Thermogravimetric analysis (TGA) and Differential Scanning Calorimetry (DSC) analyses. More than 60% of degradation occurred within 28 days. The results proved that the bio-plastic synthesized using used tea has higher tensile strength than those synthesized using black tea. Higher melting point and glass transition temperature were also obtained from the sample synthesized using used tea, confirmed by TGA and DSC analysis. The FTIR analysis confirmed the presence of various organic functional groups. The obtained results were compared with the results available in the literature. Based on the results, the developed bio-plastic samples can be successfully used in packaging applications.</p></div>","PeriodicalId":296,"journal":{"name":"Current Research in Green and Sustainable Chemistry","volume":"7 ","pages":"Article 100374"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666086523000206/pdfft?md5=ef2edb0cf5cac223343c35d9d7d91cac&pid=1-s2.0-S2666086523000206-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"54040496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five-level four-factor central composite design (CCD) using RSM was used to optimize adsorption operational conditions, namely temperature of 20–50 °C and pressure of 1–9 bar, and PEI concentration of 10–40 wt%. The optimum temperature, pressure, and PEI wt% values are 20 °C, 9.00 bar, 29.49 wt% for the input variables, and the adsorption capacity value of 8 mmol/g for the response parameter, respectively. The Bayesian Regularization algorithm optimization technique was used as a learning algorithm. The accuracy of the optimized model was calculated using the mean squared error (MSE) and R². The MLP and RBF models best MSE validation performances at 100 and 30 epochs, respectively, were 0.00011 and 0.00055. After using the experimental data as training data with the ANNs and RSM approach, the resulting model can yield satisfactory results by considering the effects of independent variables and their interactions on the objective function. The correlation coefficient (R²) and the adjusted R-squared (Adj-R²) are 0.9868 and 0.9846, respectively. Additionally, the CO₂ adsorption performances are modeled using ANN for the optimization purpose. Due to the appropriateness of the adequate precision or ratio values of more than 4, the model presented for the system is valid. The S_BET and the total pore volume of IMSiNTs/PEI nanocomposites (IMP-30) were 33.62 m²/g and 0.312 cm³/g, respectively.
