INTRODUCTION The use of fossil fuels, especially oil and gas, in recent years has accelerated and this triggers a global energy crisis. Renewable bioenergy is viewed as one of the ways to alleviate the current global warming crisis. Major efforts are devoted to developing alternative electricity production methods. New electricity production from renewable resources without a net carbon dioxide emission is much desired .On the other hand the high energy requirement of conventional sewage...
Adsorption is a low cost and important physical operation for the treatment and renovation of wastewater. Activated carbon is a highly effective low cost adsorbent and shows 10 - 15 % carbon loss during regeneration. Adsorption finds its application for removal of various pollutants from wastewater. In the present study the adsorption on activated carbon has been studied to know its adsorption potential for the removal of organic matter, phenol and chromium from the aqueous medium. Activated...
Hong Kong is facing the problem of deteriorating air pollution problem. It is because power generation produces a large amount of greenhouse gases every day. Moreover, Hong Kong relies on fossil fuels for power generation. Hong Kong has to seek alternatives, i.e. renewable energy, to displace these conventional fuels. The current progress of renewable energy adoption in Hong Kong is in a slow pace and small scale. To deal with these problems, three options are suggested in this paper, namely...
This is an essay that situation analysis of an area that would be considered a slum. According to the United Nation, a slum is defined by any one (or more) of five deprivations. These deprivations are: lack of access to water, lack of access to sanitation facilities, non-durable housing, insecure tenure and insufficient living area (more than three people per room). We were expected to produce a situational analysis of the area that would be considered a slum based on this definition and...
Over the century, the average temperature of the air near earth's surface has risen a little less than one degree Celsius. IPCC has estimated sea levels may rise 18cm - 59cm in the coming century. Since the 1980s the Western Arctic is warming 3.5 times more than the rest of the globe. There are disrupted changes in weather conditions across the globe that has led to increased floods, storms and forest-fire significantly. Other costs can comprise of higher or lower farming yields, glacier...

Water is one of the most critical natural resource available to our disposal. The supply of fresh water in terms of quality and quantity is becoming a critical issue is developing economies like India. Large stretches of rivers and water bodies are heavily polluted which can give rise to sad environmental consequences. Most of the ground water is depleting and its quality is also affected in major places. It might just become scarcely available resource in many parts of the country. So the...
One of the most define issue of our era is global climate change. It is the biggest threat to the future of life on earth. Rising average temperature, high tide levels, ocean salinity and acidity (pH), wind patterns and extreme weather events including droughts, heavy precipitation, heat waves and the intensity of tropical cyclones like hurricanes and typhoons are some extreme weather events as a result of climate change. So, climate change confronts humanity arguably with the most serious...
Municipal solid waste (MSW) management is a subject of great important that should be taken into account when discussing renewable energy sources. Most MSW is dumped into landfills and is considered a burden rather than a resource. Jordan is a country that can make use of MSW conversion since it is a developing and energy dependent nation. MSW can be converted into cellulose using the steam autoclaving process. Then, the cellulose can be converted into ethanol or bio-oil for fuel by...
The global demand for oil runs into millions of barrels on a daily basis and the demand keep on rising. To keep up with the rising demand, petroleum companies have gone into unexplainable lengths in search of new and reliable sources of oil. Oil drilling has been done in almost all places on the earth's surface; however, the oil drilling companies could not obtain sufficient oil to satisfy the global demand for oil. Considering that three quarters of the earth's surface is covered with water,...
