This thesis examined Aboriginal views on nuclear fuel waste management in Canada and assessed the concerns and issues Aboriginal people are likely to voice at future interactions and deliberations in the next siting phase. A content analysis method was used to examine the entire public record produced during the 1996/1997 Federal Environmental Assessment Review Panel hearings held on the Environmental Impact Statement for the concept of geological disposal of nuclear fuel waste. The content analysis indicated that Aboriginal peoples have continued to express opposition to the geologic disposal concept with intensity and consistency as demonstrated by measures of issue frequency and number of lines expended on each issue in the testimony. Further, the study indicated that native views remained consistent when compared with earlier scoping hearings in 1991, and that their positions were substantively and culturally different than non-native responses to the concept. In addition, two case studies were examined where natives in North America have been confronted with, and expressed views on, nuclear fuel waste storage or disposal, in order to further demonstrate the consistency of native views. The study found that Aboriginal responses have likely influenced the consideration of alternative disposal concepts in the long-standing Canadian nuclear waste management process.

The circular economy (CE) model has become highly relevant in recent years, with the electronics industry being one of the divisions that have thought about its application. Regardless of just a constrained measure of writing being accessible on waste electric and electronic equipment (e-waste), electronic waste or e-waste is a developing and quickly developing test for waste administration in the world. E-waste is a term for electronic items that have turned out to be undesirable, non-working, or outdated, and have basically come to the 'part of the arrangement', inside only a couple of brief years, given the quick innovative advances inside the business. E-waste is created from anything electronic —PCs, TVs, screens, PDAs, PDAs, VCRs, CD players, fax machines, printers, and coolers— and is commonly broken into two classes, information technology (IT) and consumer electronics (CE), on account of divergent systems and technologies required for recycling these products.

Management of waste is one of the major challenges faced by many developing countries. This study therefore attempts to develop a circular economy (CE) model to manage wastes and closing the loop and reducing the generation of residual wastes in Indian municipalities. Through extant literature review, the researchers found 30 success factors of CE implementation. Using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) SIMOS approach, the rating and weight of decision makers (DMs) for each factor were collected. A structured questionnaire has been developed incorporating all these 30 factors, to extract the most important factors. The data was collected from top 10 officials (DMs) from the Chennai municipality, who handle three regions (metropolitan, suburbia and industrial). Based on the TOPSIS SIMOS analysis, nine CE implementing factors (critical success factors (CSFs)) among the 30 variables that were significant based on the cut-off value was identified. A CE model has been proposed based on these nine CSFs for waste management in India.

<strong>Aim:</strong> This study aims to identify, develop, and determine the most suitable concept of solid waste management to be applied in Ifale Village, Yobeh Village, Putali Village, Atamali Village, and Asei Besar Village. Until now, the application of solid waste management system in Jayapura is still far from what people expected since it has been unable to serve the communities who live in rural areas on the islands around Sentani Lake. As a result, 12,554.38 liters/day of solid waste generated by the community in these regions is left untreated. <strong>Methodology and Results:</strong> The study is using the Analytic Hierarchy Process (AHP) method. The AHP calculations show that the idea of handling solid waste in an integrated treatment facility—following the initial sorting on the household scale—has the highest priority weight (2.05) compared to the other alternatives. Hence, it has been chosen as the best solid waste management concept that can be applied to the study sites. Based on the results as well, the main criteria to be considered include the environmental aspects, social aspects, and technical aspects with each weighing value of 0.534, 0.186, and 0.147, respectively. <strong>Conclution, significans and impact study: </strong> The sub-criteria with the highest priorities to be considered in making the decision are the soil pollution (due to produced leachate), air pollution (potentially in the form of stench and gas emissions), the transmission of disease vectors, public participation, and the operational convenience.

The circular economy aims to reduce the volume of waste generated in the world, transforming it into resources. The concept of indicator of circular economy was introduced to evaluate the improvement obtained regarding efficiency in terms of reduction, reuse and recycling of waste generated on the campus of the University of Lome (Togo). These indicators showed that 59.5% of the waste generated on the campus in 2018 could be introduced into the circular economy paradigm through composting, and 27.0% of the energy consumed could be replaced by clean energy obtained from biogas. The entire plastic fraction can be introduced into the circular economy paradigm by reusing plastic bottles and selling the rest in the port of the city. Thus, the income obtained could range from €15.5/day in 2018 to €34.5/day in 2027. Concerning old tires, 1.5% of the rubber needed to pave the entire roadway of the campus could be replaced by the waste generated by the tires currently existing there. Consequently, waste management on the campus could be controlled thanks to these indicators, and this could serve as a model for the rest of the country.
