Technology Osterfelder Strasse 3 D-46047 Oberhausen, Germany Tel. +49 208 8598-0 e-mail info@umsicht.fhg.de INTRODUCTION Despite of its appearance, the food-processing industry is generally agreed to be one of the major sources of environmental pollution in industrialized countries. Emissions of gaseous components, aqueous effluents containing heavy loads of biodegradable organics (high BOD values), and solid or pasty residues of different compositions are frequently accompanying phenomena of food

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

management would be polar-orbiting satellites that aviate in low-set ambit, but provide high spatial resolution. Infrared sensors would pick up floods, thermal sensors would spot the fires that are active, and microwave sensors are used to measure earth’s deformations before and during earthquakes or volcanic eruptions. The major disaster in the developing world would be the drought in Africa. This kind of disaster along with many others starts slowly and may be predicted in advance. “The cause of droughts

level as well as occupancy, and fresh air on demand. Air conditioning consumes nearly 25% of world energy and a major contribution can be made by this industry towards reducing global warming. We keep our homes and work places cool in summer and warm in winter. The sum total of all our pollutions has already added half a million million tons of carbon-dioxide to the atmosphere which has changed the world so completely that hardly any of our decedents will be there to see it. We will be thinking selfishly

The Sun the heat of the sun is about equivalent to burning a billion trillion tons of coal an hour. Even though only a small fraction of that heat ever reaches the earth it is still more then enough to power the whole world. People seemed to realize the importance of the sun around 30,000 BC. This was when people first started planting crops of wheat. They realized plants did better when planted in the sun over the shade. This caused them to worship the sun as a God

Global Warming and Climate Change i.e. how we humans have brought this upon us by increasing CO2 emissions and how our situation can be improved. He first highlights the vulnerability of the Earth’s Atmospheric Shell which is being filled with pollution and is so thin that we’re capable of changing its composition. As said by him “The sun's radiation comes in the form of light waves and that heats up the Earth. And then some of the radiation that is absorbed and warms the Earth is reradiated
