Utilizing Landsat (Level 2) imagery and the Time-weighted Dynamic Time Warping (TWDTW) classification method, the research assesses urban sprawl with high accuracy (98.87%, 96.01%, and 96.53% for 2011, 2015, and 2022, respectively). Urban expansion was predominantly through extension, with a 9.19% increase in urban areas. The study also calculates Urban Hotspot Zones (UHs) and the Urban Thermal Field Variance Index (UTFVI) from Land Surface Temperature (LST) data, highlighting the growth of urban hotspots. The Partial Least Squares Regression (PLSR) reveals that development type affects the Urban Heat Island effect and extension is the most determining factor for ecological change. A local level analysis reveals that nearly all unions, except Shimulia and Pathalia, experienced a rise in areas with adverse ecological conditions, with Tetulihora, Amin Bazar, Ashulia, and nearby areas facing the most significant ecological deterioration due to urbanization (∼50%). The findings underscore a considerable decline in the region's ecological health due to urban expansion, urging policymakers to integrate stable ecological zones into urban planning for sustainable development.</p></div>","PeriodicalId":34388,"journal":{"name":"Case Studies in Chemical and Environmental Engineering","volume":"10 ","pages":"Article 100819"},"PeriodicalIF":0.0,"publicationDate":"2024-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666016424002135/pdfft?md5=c77d19c76e9367b7141f9285e361b51c&pid=1-s2.0-S2666016424002135-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141479115","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}

It was determined that the optimal total energy consumption for the evaporation of 1 kg of moisture during the filtration drying of corn alcohol distillery stillage from the initial moisture content of the material ω₁ = 72.78 % wt. to the final value ω₂ = 14 % wt. is 9468.96 kJ/kg H₂O or 2.63 kW h/kg H₂O for the following process parameters: the height of the layer of dried material H = 120 mm, the thermal agent temperature T = 90 °C, the thermal agent velocity v₀ = 1.76 m/sec. Based on the selected optimal parameters of the filtration drying process of corn alcohol distillery stillage at the experimental installation, an evaluation calculation of the efficiency of filtration drying in industrial conditions was made. The total amount of energy required to dry ⁓ 1000 kg of corn alcohol distillery stillage in the filtration drying installation is approximately 1923.91 kW h. The total energy consumption for the removal of 1 kg of moisture during the test material drying at an industrial filtration drying installation is approximately 2.64 kW h/kg H₂O. To compare the effectiveness of the filtration method of drying for corn alcohol distillery stillage, it was calculated for drying under a similar technical task in a rotary dryer. During the drying of 1000 kg of corn alcohol distillery stillage, a total of approximately 2146.91 kW h of energy is required, and the total energy consumption for removing 1 kg of moisture during the corn alcohol distillery stillage drying in a rotary dryer is approximately 3.13 kW h/kg H₂O. It was calculated that the use of the filtration drying method makes it possible to reduce the specific energy consumption for removing 1 kg of moisture by 15.65 % with the required amount of thermal agent compared to drying in a rotary dryer. The use of filtration drying in industry would have a higher economic effect, given the higher heat losses in a rotary dryer to the environment and the need for energy-intensive auxiliary equipment for rotary dryers.</p></div>","PeriodicalId":34388,"journal":{"name":"Case Studies in Chemical and Environmental Engineering","volume":"10 ","pages":"Article 100820"},"PeriodicalIF":0.0,"publicationDate":"2024-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666016424002147/pdfft?md5=f6f2bc4f6c2f81cacf0e9adb72465a84&pid=1-s2.0-S2666016424002147-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141478979","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}

Polyethylene terephthalate (PET) plastic, used in food and beverage packaging, is the most accessible plastic for recycling. Recycling PET plastic waste can address the issue of waste management and support a circular economy, while protecting the environment. However, consumer participation is crucial for maintaining recycling programs. In this study, we determined the driving forces of customer participation with respect to post-consumption PET waste. The Theory of Planned Behavior (TPB) was used to understand the factors that motivate the consumers’ recycling intentions. We conducted a survey to assess the post-consumption behavior related to PET usage (with 294 respondents), using a questionnaire; to analyze the survey results, we used a structural equation model with partial least squares (SEM-PLS). The attitudes, moral norms, and consequence awareness of the consumers significantly affected their recycling intentions. Perceived behavior and subjective norms did not affect this desire. In Indonesia, consumer behavior after PET consumption primarily involves disposal. This study improves the understanding of consumer behavior and can help businesses and governments to implement strategies that encourage consumers to return used PET goods. In addition, this study enriches the literature on reverse logistics from a consumer perspective.</p></div>","PeriodicalId":34388,"journal":{"name":"Case Studies in Chemical and Environmental Engineering","volume":"10 ","pages":"Article 100807"},"PeriodicalIF":0.0,"publicationDate":"2024-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666016424002019/pdfft?md5=aed5d1161cd232c15f4c52c330ba3a4a&pid=1-s2.0-S2666016424002019-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141479137","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}
