Individual Assignment 2: LCA of two products Life Cycle Assessment of Nissan Cars *ASR: Automobile Shredder Residue. ASR is what remains after material recycling is done to recover as much ferrous and non-ferrous metallic material as possible from the automobile shredder residue. Nissan conducted LCAs since the early 1990s, and made quantitative comparisons to understand the environmental impact of materials that were changed in the following parts

house, farmers use greenhouses to trap warm air so they can grow plants that normally do not grow in colder months all year long. Now taking this in to a large scale, by driving cars, planes and other things that burn gas to run, we are putting more carbon dioxide in the air, which traps warm air, causing the earth to become warmer then what would be normal. Scientist have taken satellite pictures of the polar caps showing that the glaciers have been melting since 1850, which they claim is because

mechanical work. An example of chemical work would be the process of ATP synthesis, specifically the Krebs Cycle. Krebs Cycle is the central metabolic pathway in all-aerobic organisms. The cycle is a series of eight reactions that occur in the mitochondrion, specifically in the matrix. These reactions take a two-carbon molecule (acetate) and completely oxidize it to carbon dioxide (Case). This releases carbon dioxide as well as water, therefore changing the chemical property of what was first broken down and

Warming has been a main topic for discussion for many years now. Most people know that the question is whether global warming is a natural cycle or whether it is caused or triggered by human activity. Different scientists have different opinions on this topic and have gone to great lengths in trying to find the most accurate answer. Some say there is a natural cycle out there and that earth’s temperatures increase due to a natural path that is perfectly normal. The fact is that earth left the natural

commonly consists of a fabric (Carbon, Kevlar, Glass, etc.) impregnated with a resin maintained in a pre-gelled condition. The primary resin matrix used is epoxy. However, other thermoset resins are made into prepregs including BMI and phenolic resins. Carbon fiber is first developed in 1958 in Cleveland, OH, by heating rayon strands which was of relatively poor quality and strength. Then, a few years later, the Japanese developed a chemical process for manufacturing the carbon fibers which is still in

process that keeps the earth at temperatures that are livable. Energy from the sun warms the earth when its heat rays are absorbed by greenhouse gasses and become trapped in the atmosphere. Some of the most common greenhouse gasses are water vapor, carbon dioxide, and methane. If there were no greenhouse gasses, very few rays would be absorbed and the earth would be extremely cold. When too many rays are absorbed, the earths atmosphere starts to warm, which leads to global warming. Global warming can

Change Review which presented its draft report on 4 July 2008 (with the final report submitted in September 2008). Upon receiving the draft report, Climate Change Minister, Penny Wong, issued the Government discussion paper on emissions trading, titled Carbon Pollution Reduction Green Paper. Since this paper was released, and the recommendations stated, turbulent times for all involved has ensued. With the ETS to be made effective sometime in 2010, the government has had to fight tooth and nail in the
