Assessing the environmental impact of five different life cycle scenarios for brick masonry wall

Environmental impact assessment is one of the major concerns due to the threats of global warming. To this end the impacts of built environment are analyzed at several levels, one of which is assessing the negative impact of building components. This paper presents the impact of solid brick masonry walls (fired clay brick and cement mortar) on the environment according to five different end-of-life scenarios that depend on a combination of reuse, recycling and landfill options in varying ratios. The life cycle impacts of a brick wall have been analyzed with the help of Sima-Pro (PRé-NL, 2014) LCA software [1]. The results are obtained in terms of eco-points in three sub categories i.e. human health, ecosystem quality and resources. In order to conduct the analyses, (whenever the software database proved to be inadequate) data were obtained from literature and observations; such as thickness requirements of walls according to Turkish Standards, possible lifetime estimations of walls and units, reclaiming, reusing, land filling requirements, ratios and applications as well as transportation distances and facilities. The findings indicate that total landfill has the highest level of negative impact and the manual reclamation with reuse-landfill combination has the lowest level of negative impact on the environment, for these three categories.

Assessing the impact of climate change on Mogan and Eymir Lakes' levels in Central Turkey
Yagbasan, Ozlem; Yazıcıgil, Hasan (2012-05-01)
Global warming is likely to have significant effect on the hydrological cycle. Some parts of the world may see significant reductions in precipitation or major alterations in the timing of wet and dry seasons. Climate change is one of the serious pressures facing water resources and their management over the next few years and decades. As part of the southern belt of Mediterranean Europe, Turkey is highly vulnerable to anticipated climate change impacts. The changes in global climate will seriously affect i...

Global warming and climate change have been affecting the conditions and future of inland waters. Turkey's important two closed basins, Konya, and Burdur Closed Basins (KCB and BCB) are facing with drought and many of the lakes in these basins are drying or already dried out. Monitoring the lakes and mapping lake parameters (e.g., surface water area, electrical conductivity - EC) are important to increase the awareness about the situation of these lakes. Modified Normalized Difference Water Index (MNDWI) is...
Modeling the current and future ranges of Turkish pine (Pinus Brutia) and oriental beech (Fagus Orientalis) in Turkey in the face of climate change

Climate change is widely recognized to have potential impacts on global biotic and abiotic systems. One of the major impacts is expected on species distributions. Species distribution models (SDMs) are used for estimating the relationship between species occurrences at sites and environmental and/or spatial characteristics of those sites. SDMs can be used to understand possible responses of species to climate change. Despite some sources of uncertainty, projections onto future climate are useful and cost-ef...
Modeling of carbon dioxide sequestration in a deep saline aquifer
Başbuğ, Başar; Gümrah, Fevzi; Department of Petroleum and Natural Gas Engineering (2005)
CO2 is one of the hazardous greenhouse gases causing significant changes in the environment. The sequestering CO2 in a suitable geological medium can be a feasible method to avoid the negative effects of CO2 emissions in the atmosphere. CO2 sequestration is the capture of, separation, and long-term storage of CO2 in underground geological environments. A case study was simulated regarding the CO2 sequestration in a deep saline aquifer. The compositional numerical model (GEM) of the CMG software was used to ...
Modeling of enhanced coalbed methane recovery from Amasra coalbed in Zonguldak coal basin
Sınayuç, Çağlar; Gümrah, Fevzi; Department of Petroleum and Natural Gas Engineering (2007)
The increased level of greenhouse gases due to human activity is the main factor for climate change. CO2 is the main constitute among these gases. Subsurface storage of CO2 in geological systems such as coal reservoirs is considered as one of the promising perspectives. Coal can be safely and effectively utilized to both store CO2 and recover CH4. By injecting CO2 into the coal beds, methane is released with CO2 adsorption in the coal matrix and this process is known as enhanced coal bed methane recovery (E...
