This study aims to measure the relationship between environmental management, cleaner production,\u0000 and organizational performance. Within this context, a survey of 372 companies was performed in the agro-industrial, manufacturing and construction sectors in three important productive regions of Colombia. Structural Equation Modeling was used for data analysis. The economic sector moderated\u0000 the relationship between the latent variables. This phenomenon was analyzed using a multi-group technique. The results show that Cleaner production is positively related to Organizational Performance at corporations. The results show that Cleaner production is positively related to Organizational\u0000 Performance at corporations. It was also observed that Environmental Management influences Cleaner Production. Finally, it is worth noting that productive sectors in Colombia tend to be committed to circular economy practices, some to environmental management and others to cleaner production\u0000 with an impact on organizational performance. The result of the study may be useful for domestic and foreign investors and managers, for analysts and researchers, and for educators. The rationale behind this is an understanding that interactions between environmental management and cleaner\u0000 production and organizational performance will influence the academic community or business activity to generate behaviors favoring the environment and sustainable development. These findings will be extremely useful for promoting future research studies on establishing an improved framework\u0000 for the promotion of environmental management and cleaner production practices primarily among Colombian productive companies. This work can also serve as a reference for other industrial sectors and countries.","PeriodicalId":35783,"journal":{"name":"Journal of Solid Waste Technology and Management","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46389565","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 aim of this study was to fix the functions, algorithms as well as optimization of methods for soft computing system such as ANFIS, SVM, and\u0000 ANN based on their best performance. In this study, soil samples were collected from eighty five distinct locations in and around of a selected open disposal site at old Rajbandh, Khulna, Bangladesh at a depth 0-30 cm from the existing ground surface. In the laboratory, the concentration of\u0000 heavy metals such as Pb, Cu, Ni, Zn, Co, Cd, As, Sc, Hg, Mn, Cr, Ti, Sb, Sr, V and Ba in soils were measured. The soft computing systems such as ANFIS, SVM, and ANN were implemented for the analysis of heavy metal concentrations in soil. The result reveals model with SCP, gaussmf, linear and\u0000 hybrid was the best-fitted model of ANFIS. In addition, in SVM analysis, the model SVM-RBF with 15 folds was selected. In ANN, the model LT (Levenberg-Marqardt and Tansig functions) with neuron structure 2-10-1 was selected. The accuracy of the predicted results was checked based on the acceptable\u0000 limits of prediction parameters such as R value, RMSE, MAPE, GRI and percentage recovery. The result demonstrates that ANFIS model was a reliable technique than that of other counterparts of SVM and ANN with the acceptable degree of robustness and accuracy. Therefore, the performance of soft\u0000 computing systems may be expressed by the sequence of ANFIS > SVM > ANN. Here it can be noted that one can easily be computed the concentration of a particular heavy metal in soil by inserting GPS values (latitude and longitude) only in the developed rule viewer of ANFIS.","PeriodicalId":35783,"journal":{"name":"Journal of Solid Waste Technology and Management","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70940753","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}

Method: For the development\u0000 of the research, the logistic model of differential equations (Verhulst, 1838) and a theoretical model of finite difference equations associated with an empirical model of log-linear regression were used to analyze the growth prospects of e-waste, over time, when technological advances are\u0000 estimated, as well as the potential reaction of society. Main results: The results show that there is a point of impatience in society that can be measured, as long as the specificities of each type of e-waste are known; and that the volume of e-waste grows exponentially\u0000 over time, being influenced, in part, by the evolution of technology, considering the electronic products made available to society as a proxy, which is driven to consume, among other motivations, by functional obsolescence. Relevance/Originality: The results are important\u0000 because they indicate that if there are no more rigid, efficient and effective regulatory measures, and if there is no paradigm shift in the production system, from extraction to final destination, there is likely to be a collapse in drainage systems, treatment and final disposal of e-waste\u0000 on a global scale, with severe consequences for ecosystems, health, economic and social systems, greatly increasing our ecological footprint, thereby threatening the maintenance of life on Earth. Theoretical/methodological contributions: The study contributes to the understanding\u0000 of the behavior of e-waste and the influence of technology on its growth, as well as to the logical deduction of the society's point of impatience regarding the use of the materials that generate e-waste, reinforcing the originality of the research and promoting a deeper understanding of the\u0000 topic.","PeriodicalId":35783,"journal":{"name":"Journal of Solid Waste Technology and Management","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46570705","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}
