With the increase in world population and the associated increase in raw material, clean water and energy demands, seeking for innovative and sustainable methods to decrease human-made environmental footprint becomes a task of utmost importance to reduce emissions and waste generation. Uranium-based atomic energy generation has an enormous potential to efficiently supply energy demand at the cost of high environmental impact on water bodies. Therefore, estimating the environmental impacts of the uranium recovery systems from desalination waste is a necessity. This study assessed the environmental impact of uranium recovery method from brine via AF1 and PAN-AO amidoximated adsorbents and compared them with the conventional uranium mining methods. As a life-cycle impact assessment method International Reference Life Cycle Data System was conducted with 16 impact categories considering cradle to gate analysis. The results for AF1, PAN-AO and all conventional uranium extraction methods showed that recovery of uranium in the long run is more effective than the conventional procedures. The sensitivity analysis results reveal that hydroxylamine, hazardous waste disposal are the most influential parameters during the uranium recovery via adsorbent methods. Comparative analysis between energy sources used in adsorbent recovery processes indicated that solar energy has the lowest environmental impacts among all kinds of energy scenarios. This study concluded that an alternative sustainable industrial process to obtain uranium is actually applicable. Hence, developing a uranium recovery strategy from brine should be considered while uranium mines are under investigation.

A comparison of renewable energy systems (onshore wind, offshore wind, conventional pv) for Bozcaada Island
Şentürk, Ayşe Eylül; Oğuz, Elif; Department of Civil Engineering (2020)
Renewable energy sources have been considered as a sustainable solution for energy production without polluting the environment. Shifting from fossil fuel to renewable sources has been suggested by many scientists to decrease the global warming effects. As several renewable energy sources exist such as solar, wind, hydro-power, etc., it is important to determine the appropriate option for a selected region in terms of maximizing efficiency and power output as well as minimizing life cycle costs (LCC). There...
Comparative Evaluation of CO2 Emissions in Europe and Turkey Using GIS
Demirel, Nuray (2018-11-30)
Sustainable development requires extraction and utilization of energy resources on a viable basis for the welfare of human beings and global growth. An increased focus on sustainable development and global warming imposes policy-makers and decision-makers to prioritize environmental responsibility while maximizing economic benefits to the industry. Therefore, evaluating environmental aspects and potential impacts associated with energy resources is essential. Turkey, as a signatory of Kyoto protocol, needs ...
An Analysis of public use bicycle systems from a product service system perspective
Keskin, Duygu; Brezet, Han C; Börekçi, Naz Ayşe Güzide Z.; Diehl, Jan Carel (null; 2008-04-21)
Recent studies on sustainability indicate that the concept of the Product-Service System (PSS) is a promising approach to dematerialise the economy and reduce the environmental impacts of industrial and consumption activities. Considering the urban scale, mobility is one of the challenges that should be addressed and improved for a better quality of life for residents and lower pollution levels for the environment. In this respect, this study aims at analysing Public Use Bicycle (PUB) systems from a PSS per...
A techno-economic feasibility study of a gridconnected hybrid solar pv-wind power generation system in Zimbabwe
Samu, Remember; Fahrioğlu, Murat; Sustainable Environment and Energy Systems (2019-1)
The depletion of fossil fuel resources on a worldwide basis and an increase in greenhouse gas emissions and climate change as a whole have caused an urgent search for alternative sustainable energy sources to cater for the rising energy demands. The demand of energy is rapidly growing in both developing and developed nations thus making hybrid renewable energy power systems (RES), comprising Solar Photovoltaic (PV) and wind energy to be chosen as one of the best alternatives. However, on the downside, these...
