ABSTRACT: In this paper, mining techniques of uranium were investigated. Basically three type of mining techniques are applied. Basic mining techniques are underground mining, open pit or surface mining and in-situ leaching mining methods. Each of them has several advantages and disadvantages to the other. Specifications of each technique was evaluated in this study. Uranium mine wastes present the most significant waste management problem because of their large volume and their radioactivity. Most of the constituents in these radioactive wastes are found naturally in soils and bedrock. During the uranium mining and milling operations, natural radioactive material changes its chemical and physical form so that their potential for mobility is increased. The mobility results leakage to the environment and the public.

ABSTRACT: Pandemics affect the very existence of human life and their effects going beyond human life to the environment. Natural resources within evolving city milieus require sustainable environmental management. In the COVID-19 pandemic, disposal of face masks in rivers have been witnessed illustrating the implications of COVID-19 on solid waste management and ultimately on the environment. The risks associated and enhanced from improper waste management continues to have adverse impact on water bodies like rivers further aggravating the previous conditions of pollution, which contribute to the effects of climate change. Interestingly, COVID-19 pandemic has had positive environmental effects especially during the lockdowns evidenced by reduced travelling hence reduced global carbon dioxide emissions thereby resulting in improved air quality. However, the pandemic has imposed a further strain on the municipal waste system of many developing economies whose waste management structures and frameworks are still straining from doubled waste generation. As part of the COVID-19 protocol, advisory of wearing face masks was made mandatory for prevention purposes. Unfortunately, a constraint exists in developing protocols towards the management of the used face masks, gloves and PPEs. Increased generation of used face masks and gloves further accelerates indiscriminate dumping of these wastes not only in water bodies but also in dumpsites. Burning of these wastes will lead to increased production of greenhouse gases that have been cited as contributing to climate change. Beyond the COVID-19 pandemic, it is advisable for governments in developing countries to treat waste management as an essential service to avoid future foreseeable and unforeseeable adverse impacts on the environment.

ABSTRACT: This study assesses the environmental impact of bauxite mining and the attempts at managing those impacts around the three different bauxite mining communities “zones” (Sangarédi, Boké, Fria) in the western Guinea. Mining sector is important to the country’s economy; it represents 75 to 85% of resources exports by year, especially bauxite and figures prominently in the government's development priorities, evidenced by the broad movement of reforms undertaken by the authorities since 2010. In this context, these reforms aim both to minimize the risks while maximizing the benefits of the mining activity. This implies among other things, a better distribution of income from the mine, strict compliance with environmental standards, to record activity in a sustainable development perspective. To better understand these reforms and scope, this research evaluates the existing framework and innovations of the new reforms in the context of sustainable development. The researcher conducted a data collection, a series of interviews with resource persons (The local communities, the Ministry of Mines, mining companies and NGOs working in the mining sector), to analyze the Environmental and Socio-economic impact of mine. The results showed that the mining code of 1995 was both inadequate and very rarely applied in the field. In contrast, the 2011 code contains advanced Transparency important for equitable sharing of benefits and stringent measures for environmental protection. Thus, this 2011 mining code is more attractive and oriented towards sustainable development.

ABSTRACT: Energy crisis and environmental degradation is considered most talked of the topics of modern global development. Medical waste has dangerous impacts on the environment. Besides, load shedding has come to be a great problem in socioeconomic development of Bangladesh for the reason that of the serious electricity crisis. This study also focused on energy recovery potentiality from plastic content of medical waste (PCMW) by converting it into electric energy. This plastic waste integrates an enormous amount of energy and consequently, attention in new renewable sources of energy from these wastes has been augmented, at the present time. Bangladesh as well as Jessore city faces an excessive environmental problem because of improper management of medical waste. This study demonstrated that the medical waste generation rate in Jessore city was found to be approximately 3 ton/day which is about 6.89% of total waste generation in this city throughout the study period. Besides, electric power generation projections from the PCMW were estimated at 74448 kWh per year respectively. This study suggested that appropriate PCMW management policy as well as awareness increasing regarding the management of PCMW is requirement for the development of existing status of living condition.
Delimiting Future Urban Sprawl Boundaries Using a GIS-based Model for Ecological Sensitivity Index Assessment and Optimization Techniques. The Case of Mytilene (Lesvos Island, Greece)
European Journal of Sustainable Development Research, 2019, 3(1), em0074, https://doi.org/10.20897/ejosdr/3975
ABSTRACT: Delimiting urban sprawl boundaries have been generally regarded as a regulatory policy measure to control chaotic and sparse urban expansion and for the protection of ecological areas towards sustainable development. The conservation of ecologically sensitive areas plays a key role in environmental protection; so, harmonizing urban sprawling with nature conservation can be viewed as a binary compatibility planning problem. This study aims to employ a geographical allocation model, based on the minimization of the environmental cost in order to apply complex spatial clustering techniques. Firstly, five ecological sensitivity factors affecting the ecological footprint of the study area are modeled through Geographic Information Systems (GIS) and Analytic Hierarchy Process (AHP) method in order to evaluate the Ecological Sensitivity Index. Then, several spatial objectives and constraints such as distance from the shoreline, continuity, and compactness are applied and finally, the most optimal areas are extracted for future urban sprawl. Spatial regulations, siting rules considerations and scenarios based on the parameters of the spatial clusters outputs are tested to the commune of Mytilene, located on Lesvos Island, Greece, where strong land use changes have been recorded by the urban sprawl over the last three decades.
Medical Waste Management is Vital for Safe Town Development: An Incident Study in Jessore Town, Bangladesh
European Journal of Sustainable Development Research, 2018, 2(3), 36, https://doi.org/10.20897/ejosdr/2668
ABSTRACT: Health care institutions (HCIs) generate waste which can causes various injuries and infections to the patients, healthcare workers and also causes harm to the surrounding environment. Medical waste management (MWM) is vital for safe town development and the misconduct of medical waste may be a significant risk factor for the infectious diseases diffusion on our environment. The study carried out on 22 HCIs included public hospital, diagnostic centers, private hospitals and clinic in Jessore town of Bangladesh. This present study focused on the existing management structure, generation rate and difficulties of MWM. An inadequate number of HCIs are following the MWM method over their self-management. The findings of this study exposed that around 3 ton of medical waste is produced per day that is about 5.56% of entire waste production in this town. Over on an ordinary 0.98kg/day/bed medical waste that covering 10.89% infectious, 15.82% plastic, 3.46% sharp, 3.87% pathological, 60.94% domestic and 5.52% pharmaceutical waste were generated in this town.

ABSTRACT: The aim of this paper is to offer an exploratory review of the approaches to sustainability within the UK’s waste management industry. The paper begins with brief outlines of the waste management industry in the UK and the growing interest in corporate sustainability. This is followed by a review of the most recent sustainability reports published by the leading waste management companies operating within the UK and the paper concludes by offering some reflections on current approaches to sustainability within the industry. More critically the authors suggest that the selected companies’ commitments to sustainability are couched within existing business models centred on continuing growth and consumption and that current policies might be viewed as little more than genuflections to sustainability. The paper provides an accessible commentary on current approaches to sustainability in the waste management industry within the UK and as such it will interest professionals working in the industry as well as academics and students interested in management and business studies, resource management and sustainability.
