Cropping Systems On Greenhouse-Gas (GHG) Emissions

[Name of the Institute]Cropping Systems On Greenhouse-Gas (GHG) Emissions

Introduction

There are a number of Universities and research groups who utilize the green power as it is equivalent to avoiding greenhouse gas emissions of approximately 27,000 passenger vehicles each year. With the purchase of  green power from renewable sources, these institutions are spurring the development of the nation's green power market and reducing harmful air pollution. Their commitment to renewable energy, is contributing to the growth in green jobs and a green economy. Blenders, stockpots and dryers have their separate uses in the home. But would you believe that the future of the environment and foreign oil dependency could be influenced by these simple appliances? University of West Georgia professor Dr. Ben de Mayo received a patent from Canada for a new oil-acquiring system. He envisions the final product will resemble a blender spanning 60 feet across and standing several stories tall. It will function like a clothes dryer and utilize heat and rapid spinning to separate bitumen, an unrefined crude oil, from oil sands. Currently bitumen is extracted from the sand through a method that de Mayo deems unclean and inefficient. Imagine a giant stockpot of boiling water. The oil-rich sand is dumped into the pot and then sinks to the bottom while the oil floats to the top (Bremer, 2009).

Afterward, the oil is skimmed from the surface of the water like fat from boiled chicken, leaving behind a toxic broth that is dumped into man-made lakes. These highly polluted ponds have the unfortunate side effect of attracting wildlife. The system de Mayo devised can be best described as a large-scale dryer. The funnel-shaped object would spin the heated sand at rapid speeds and separate the bitumen. The idea was so simple I thought someone would have done it already. His experimentation with the technique utilized a 3300-rpm centrifuge, a machine used for spinning objects at high speeds. First he heats the oil sand before adding it to the centrifuge, where it spins rapidly for about an hour. The end result renders 80 percent of the bitumen from the sand.

Discussion

The current process takes more fuel to produce than it actually yields. The de Mayo process requires 75 percent less energy and no water. Because of the lower energy requirements, the device would also decrease the production of green house gases. The absence of water used in the process would nullify water pollution caused as a result of the current method (Brown, 2008).

 Current study results from the report, "Fe(III) fertilization mitigating net global warming potential and greenhouse gas intensity in paddy rice-wheat rotation systems in China," have been published. According to the authors of recent research published in the journal Environmental Pollution, "A complete accounting of net greenhouse gas balance (NGHGB) and greenhouse gas intensity (GHGI) affected by Fe(III) fertilizer application was examined in typical annual paddy rice-winter wheat rotationcropping systems in southeast China. Annual fluxes of soil carbon dioxide (CO(2)), methane (CH(4)) and nitrous oxide (N(2)O) were measured using static chamber method, and the net ecosystem exchange of CO(2) (NEE) was determined by the difference between soil ...
