This article first analyzes and evaluates the state of tourism development in the process of urbanization. Using the entropy-weighted TOPSIS model, Zhuhai’s tourism urbanization can be divided into four stages: the slow development stage before 2007, the first prosperous stage from 2007 to 2013, the second prosperous stage from 2014 to 2020, and the post-pandemic stage after 2020. Secondly, the ecological resilience is evaluated using an indicator evaluation method, and since 2014, the ecological resilience of Zhuhai has tended to stabilize. Finally, the coupling coordination degree of the two are evaluated. Since 2005, this process has gone through stages of imbalance, benign coordination, and high-quality coordination.\u0000 ","PeriodicalId":11703,"journal":{"name":"Environmental Research, Engineering and Management","volume":"43 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140736839","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}

This research was conducted to determine the sustainability level of the Arun Lhokseumawe SEZ generated to its surrounding area before and after the exhaustion of its natural gas resources. The statistical matching method and the Moran index used for the analysis involved 14 sustainability variables representing social, economic, and environmental dimensions. The method used includes building the sustainability index using village level data, statistical matching to find evidence of impact, and determination of the Moran index to describe its spatial patterns. Additionally, the index was used to describe the policy implication based on the current SEZ sustainability level. The results show that there is no upward trend in the sustainability index after three years of operation, except for an increase in the SEZ (inside) in 2018 which then declines again in 2021. This figure is lower than before natural gas depletion. It was found that, in 2008, the spatial pattern of the high sustainability index mainly spread to areas outside the Arun Lhokseumawe industrial area. Meanwhile, in 2021, the spatial pattern of a high sustainability index clustered near the Arun Lhokseumawe special economic zone.","PeriodicalId":11703,"journal":{"name":"Environmental Research, Engineering and Management","volume":"180 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140740517","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}

Activated carbon obtained from pumpkin seed waste functionalized with ZnCl2 was used as an absorbent. Pumpkin seed hydrochar was characterized by FT-IR, SEM, TGA-DTA, BET, and XPS. In the experimental stages, the adsorption equilibrium time was determined as 45 minutes, the adsorbent dosage was 0.8 g and the optimum pH was 6.0. After this step, the adsorption parameters of Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich isotherms were investigated. It has been pointed out that the adsorption process fits better with the Freundlich isotherm model, and the adhesion occurs in a multilayered manner and on a heterogeneous surface. Freundlich and Dubinin-Radushkevich isotherms support that the bonding mechanism is realized by physical interactions. When the kinetic data were evaluated, it was found to be compatible with the pseudo-second-order kinetic model. The thermodynamic parameters of adsorption indicate that the system is endothermic, and the adsorption of Reactive Blue 19 on activated carbon is a spontaneous process.","PeriodicalId":11703,"journal":{"name":"Environmental Research, Engineering and Management","volume":"35 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140737733","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}

This study aims to analyze the extent to which environmental behavior manifests and assess the capacity and incentive driving forces that affect the environmental behavior of actors in the red brick industry during the COVID-19 pandemic. This research was conducted through questionnaires, data processing, and analysis of descriptive and inferential data using the Statistical Package for the Social Sciences (SPSS). The results showed that the environmental behavior of actors in the red brick industry was less good (12.12%), pretty good (69.69%), and good (18.18%). This study utilized the capacity and incentive variables as driving forces. The variables that contribute to capacity can be categorized as environmental knowledge, social capital, financial capital, natural capital, and physical capital. On the other hand, the incentive variables specifically encompass market signals and government incentives. Neither of the variables have been effective in motivating environmental behavior toward a better or optimal direction. Moreover, their concurrent influence on environmental behavior was weak (8.2%). The study of human behavior focuses on the causal chain. It is, therefore, multi-dimensional, meaning that control or influence of certain factors over behavior is relatively difficult to achieve. The optimal contribution of society toward environmental protection and control has not been realized.","PeriodicalId":11703,"journal":{"name":"Environmental Research, Engineering and Management","volume":"21 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140738256","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}

The review includes academic journal articles that were retrieved between March 2013 and March 2023 from several different databases. As part of a comprehensive literature assessment, content analysis was applied to 138 publications that were published in peer-reviewed journals over ten years. Green practices in garment manufacturing process are covered, including product design, raw material procurement, fabric spreading, cutting, sewing and assembly, washing, printing and embroidery, finishing, and packing. The review of eco-friendly production practices at each phase of the production process shows the variety and complexity of green practices in apparel production companies. However, there is a lack of research on the conditions of developing countries, where the majority of apparel production takes place, as well as on the methods used in the manufacture of garments. The study is distinct in that it focuses solely on the garment manufacturing industry, and will not include textiles because the production processes for textiles and clothing are fundamentally different. This study assists managers in building a company’s sustainability competency by outlining best practices at various phases of production. It also provides scholars with a uniform representation of environmentally sustainable practices to spur additional scholarly investigation. ","PeriodicalId":11703,"journal":{"name":"Environmental Research, Engineering and Management","volume":"40 47","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138946637","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}

The study focused on developing WPCs based on polypropylene filled with finely dispersed powders of waste products from tung oil production (PP+TOPW composites). Finely scattered powder (with an average grain size of 0.5–1.5 mm) was obtained from crushing and grinding the outer pericarp of tung fruit waste, which resulted from tung oil extraction. Tung oil is produced in Georgia from tung fruit that is grown in Tsalenjikha district, Georgia. In addition, to modify the properties of the WPCs, organic silicon oligomer tetraethoxysilane and powdered aluminum hydroxide were used as additives.  The study found that the strength properties of the PP+TOPW composites can be optimized by modifying them with tung oil and other mineral additives. The optimal strength properties were observed at a filler content of 40 wt.%, where the compression and bending strength limits were 63.5 and 36.7 MPa, respectively. The water absorption of the PP+TOPW composites was reduced by modifying them with tung oil. The PP+TOPW composites with a filler content of 30 wt.% showed 0% water absorption, and the water absorption of composites with a filler content of 40 and 50 wt.% (modified with tung oil) was very low, ranging from 0.2–0.8%.  The study also investigated the effect of modifying PP+TOPW composites with tetraethyl orthosilicate (TEOS), which increased all the strength parameters, including impact strength, and reduced water absorption, although not as much as when modified with tung oil. The introduction of a flame retardant, aluminum hydroxide, into the composite composition in the amount of 25–30 wt.% made the composites flame-retardant and low-combustible materials, expanding their potential applications, particularly in construction.  Overall, the study successfully developed WPCs using waste materials with optimized properties, which have potential for various applications, including in construction, due to their flame retardant and low-combustible properties.","PeriodicalId":11703,"journal":{"name":"Environmental Research, Engineering and Management","volume":"30 17","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139166097","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}

The relevant literature shows that the majority of the relevant studies do not consider aquifer’s natural discharge, which is expected to have a significant impact on the determination of the optimal groundwater management policy. This paper attempts to highlight the impact of considering natural discharge in the formulation of groundwater management policies. Thus, two different cases of aquifer management are considered and the corresponding time-dynamic problems are solved by considering natural discharge in order to derive optimal trajectories for a number of key variables. These cases are (1) non-intervention – full competition and (2) intervention with a tradable water rights system. The results obtained from simulations on a coastal aquifer show that indeed not considering the natural discharge leads to an overestimation of the benefits from groundwater consumption that can reach 5.79% in the case of non-intervention and in the case of intervention with a tradable water rights system. ","PeriodicalId":11703,"journal":{"name":"Environmental Research, Engineering and Management","volume":"7 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138944538","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}

In this research, subsurface flow constructed wetlands, which include vertical subsurface constructed wetlands (VSSFCWs) and horizontal subsurface constructed wetlands (HSSFCWs), are used as a sustainable and low-cost approach to improve water quality. The VSSFCW system is configured with a layer of gravel substrate, Heliconia psittacorum, and a layer of activated carbon. The configuration for the HSSFCW system is also similar but without the activated carbon layer. This research aimed to determine the quality of the post-treatment water using CWs as an eco-garden to reduce pollutants from the Brantas River. Measurement of water samples from the reactor with laboratory-scale dimensions at the Environmental Laboratory of the State University of Malang, where water samples were taken from the Dam Kadalpang, Brantas River. These measurements were made on physicochemical parameters such as pH, DO, temperature, conductivity, salinity, turbidity, TDS, BOD, and COD. There were four observation points in this research, namely VSSFCW with Heliconia psittacorum and control VSSFCW without plants, where both were given an activated carbon layer, as well as HSSFCW with Heliconia psittacorum and control HSSFCW without plants. The results of data analysis showed that both CWs systems with plants were able to reduce turbidity up to 99% and BOD with a performance efficiency reaching 89%. Both systems also removed COD with a removal efficiency of 73%. TDS was also reduced in both CWs, although there was no significant difference. Similar results were obtained in conductivity and salinity. The pH, temperature, and DO conditions at each observation point met the quality standards and recommendations of previous studies, which became one of the factors supporting the reduction performance of the VSSFCW system. The pollutant degradation capability of the CWs system shows that it can reduce pollutants in the water and it is suitable for use as raw water in the production of clean water.","PeriodicalId":11703,"journal":{"name":"Environmental Research, Engineering and Management","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138947505","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}

The yield of the crop depends on the agrophytocenosis conditions, including meteorological factors, the number of weeds, pathogens and pests, which change from year to year. Crop yield forecasts are becoming necessary to make informed crop management decisions. The paper presents the results of the multiple regression analysis of actual field data in the system of integrated protection of winter wheat crops in the conditions of the Northern Steppe zone of Ukraine. The predictive value of the models that linked yield and gluten content in grain with the number of pathogens and pests was reduced due to the statistical insignificance of correlations between indicators. In order to overcome the shortcomings of modeling, it is probably necessary to use a more reliable algorithm and a larger sample of data. Regression models reflecting the correlation of yield and gluten content in grain with relative air humidity during the phase of milky ripeness of winter wheat grain showed predictive value (R2 = 91.9–99.7%) and made it possible to determine the necessary limits of the meteorological parameter to achieve high quantitative and qualitative yield indicators.","PeriodicalId":11703,"journal":{"name":"Environmental Research, Engineering and Management","volume":"1 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138944921","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}
