Fly ash, a coal combustion product consisting fine particles is a residual, waste matter arising from the combustion of coal from boilers used for the steam generation power plant at GHCL. Its disposal at GHCL has become a huge problem. The study aims at understanding the characteristics of the generated fly ash in detail and will investigate about finding innovative, possible solution for addressing the fly ash disposal problem at GHCL. Gujarat Heavy Chemicals Ltd. (GHCL) was establish in March

“Global Warming is not a prediction; it is happening,” said James Hansen, who is professor directing the program on Climate Science, Awareness, and Solutions of the Earth Institute at Columbia University. Global climate change is the rise in the overall temperature of the Earth's climate. As the temperature rises, the glaciers would melt faster, causing sea levels to rise. In addition to that, some scientist expect that the weather patterns may become more severe. There are many effects of global

Introduction The three-phase induction machine is the most widely used rotating machines. An induction machine offers an almost constant speed within its normal operating range when operated off a constant-voltage, constant-frequency, and electric power source. Economically, the cost of purchasing these machines can be considered very low, and they require little maintenance. However, controlling the speed of this type of machine is difficult and can be considered very expensive. In this paper,

Abstract:Oil pollution has been the major environmental effect in oil producing countries particularly where crude oil exploration tales place. In Nigeria, the problem is more pronounced in the Niger-Delta region. Poultry farming is a very lucrative business in Nigeria where both chickens (layers and broilers) are found particularly in the northern part of the country. The eggshells are usually thrown and allowed to liter the environment. A column study was used to test the ability of the eggshell

Declining arctic ice, rising sea levels, decreased snow cover, glacial retreat, warming oceans, shrinking ice sheets extreme events, ocean acidification. What do these have in common? Two words: Global Warming. The Earth’s global temperature has change throughout history but never have the Earth’s temperatures have been as high as they are now. After the Industrial revolution, global warming has increasingly becoming a threat. Consequently, global warming is becoming a bigger threat that needs to

Site One - The Rangipo Desert The Rangipo Desert is approximately 1000m above sea level, East of Mount Tongariro. This fairly high altitude means the desert receives more sunlight than most places, and it is often plagued by strong northwesterly winds sweeping off the surface of the mountain. Funneling through the mountains and becoming very intense throughout the desert, these powerful winds test the durability of the vegetation growing here. These plants therefore must be accustomed to the strong

Taking into account the above considerations, in 2010, the United Nations General Assembly proclaimed a program called “Decade of Action for Road Safety 2011-2020”, whose overall goal is to stabilize and then reduce the forecast level of road traffic fatalities around the world by 2020 (Figure 2.4). The final document also included an economic support to low and middle income countries in order to achieve the objectives. Figure 2.4: Decade of Action. Objective [9] The program sets the guidelines

The wind and solar energy are omnipresent, freely available, and environmental friendly. The wind energy systems may not be technically viable at all sites because of low wind speeds and being more unpredictable than solar energy. The combined utilization of these renewable energy sources are therefore becoming increasingly attractive and are being widely used as alternative of oil-produced energy. Economic aspects of these renewable energy technologies are sufficiently promising to include them

Someone says that air pollution problem is not that serious in Hong Kong. As the Air Quality Health Index(AQHI) in Hong Kong was normally 1 to 3 out of 10 for the general stations and 2 to 5 out of 10 for the roadside stations according to the Environmental Protection Department. Well, if you just look at the Air Quality Health Index, it seems like air pollution is not that serious. However, we need to consider the concentration of the air pollutant. When it is in high level, it is not safe for

Introduction Energy is a vital element in all countries’ development. Considering the importance of energy for sustainable development, the United Nations (UN) introduced a global plan in 2012 called “sustainable energy for all (SE4ALL)” to involve all societies in providing global sustainable renewable energy by 2030. The term sustainable development has been defined in different ways, but the most commonly quoted definition is “the development that meets the needs of current generations without
