Introduction:
Aluminum is an element in the boron group with a symbol of Al, and an atomic number of 13. Aluminum is a very soft metal when pure but becomes strong and hard when alloyed, a malleable metal with a silvery gray color. Aluminum is a very reactive element so it is found in nature combined with other elements. Aluminum resists corrosion by the formation of a self-protecting oxide coating. Aluminum is the third most abundant element in the Earth’s crust, following oxygen and silicon. It makes up approximately 8% by weight of the Earth’s surface. Although this is evident, it is also apparent that aluminum is never found by itself in nature. All of the earth’s aluminum has combined with other elements to form compounds and in order to create new aluminum products; it has to be taken out of that specific compound. Aluminum does not rust like other elements, therefore it always remains strong and shiny, which means reused aluminum is almost identical to a brand new piece of metal. An electrochemical process creates aluminum. An electrochemical process is “the direct process end use in which electricity is used to cause a chemical transformation” ( E.I.A. Government). Major uses of electrochemical processes occur in the aluminum industry in which alumina is reduced to molten aluminum metal and oxygen, where than the aluminum can be used into making several different materials. Electrochemical processes, although very useful, can have serious environmental consequences. To help reduce the consequences that the production of aluminum creates, the idea of aluminum recycling comes into play.

Aluminum is the third most abundant element and most abundant metal in the Earth’s crust. Aluminum is never found in the free element state in nature. It
Aluminum is a lightweight, silvery metal. The atomic weight of aluminum is 26.9815; the element melts at 660° C (1220° F), boils at 2467° C (4473° F), and has a specific gravity of 2.7. Aluminum is a strongly electropositive metal and extremely reactive. In contact with air, aluminum rapidly becomes covered with a tough, transparent layer of aluminum oxide that resists further corrosive action. For this reason, materials made of aluminum do not tarnish or rust. The metal reduces many other metallic compounds to their base metals. For example, when thermite (a mixture of powdered iron oxide and aluminum) is heated, the aluminum rapidly removes the oxygen from the iron; the heat of the reaction is sufficient to melt the iron. This phenomenon is used in the thermite process for welding iron .
Aluminum is the third most common element in the earth's crust, with reserves guaranteed to last hundreds of years, and, in its ore, bauxite, one of the most economically significant minerals in the world. It is, perhaps, more easily recycled than any other mineral substance used by man, but mining operations still continue and are enormously valuable. Aluminum companies have been at the forefront of environmental progress and effort in the minerals industry.
...such as recycling and reducing waste has significantly helped our environment and will continue to if future generations practice these same habits. For deforestation, many organizations have strived to plant more trees and add more oxygen to the atmosphere as well as nutrients for the soil. Seeing that although humans create many negative impacts in our global environment, there are many positive arrangements in correcting these issues.
Aluminum is one of a number of soft metals that scientists call "poor" metals. It can be shaped and twisted into any form. It can be rolled into thick plates for armored tanks or into thin foil for chewing gum wrappers. It may be drawn into a wire or made into cans. Aluminum is a generally popular metal because it does not rust and it resists wear from weather and chemicals. (Bowman, 391) Aluminum is an element. Its atomic number is thirteen and its atomic weight is usually twenty-seven. Pure aluminum melts at 660.2ºC and boils at 2500ºC. Its density is 2.7 grams per cube centimeter. Aluminum is never found uncombined in nature. (Bowman, 391) Aluminum is a very useful metal that is light, easy to shape and can be strong. This makes aluminum one of the most used metals in the world, right behind iron and steel. (Geary, 185) In its pure state, aluminum is quite weak compared to the other metals. However, its strength can be greatly increased by adding small amounts of alloying elements, heat-treating, or cold working. Only a small percentage of aluminum is used in its pure form. It is made into such items as electrical conductors, jewelry, and decorative trim for alliances and cars. A combination of the three techniques has produced aluminum alloys that, pound for pound, are stronger than structural steel. Some common metals used in alloys for aluminum are copper, magnesium and zinc.(Walker, 31) The added elements give the aluminum strength and other properties. (Newmark, 41) Aluminum is one of the lightest metals. It weighs about 168.5 pounds per cubic foot, about a third as much as steel which weighs 487 pounds per cubic foot. (Neely, 214) As a result, aluminum has replaced steel for many uses. For example, some ...

Cluttered trash filled parks, waste filled rivers, and town sized landfills and that is what awaits the people of earth if nothing is done to aid in the efforts to keep the world clean and recycling is one best and most beneficial ways to do just that. The truth is a frightening thing however it is true if we don’t act to improve our habits soon it might just be a reality, recycling should be mandatory for all households in order to prevent this trash filled grim future.
Recycling. What does this word mean to you? Do you recycle? Do you support or oppose the act of it? What is written in the following paragraphs may or may not help you make this one special planet in our solar system we call Earth; the only planet scientists know supports life. Recycling benefits many aspects of life. Recycling benefits the aesthetics of our daily environment, it makes our family and friends safer from sickness, it boosts our economy, and it allows us to make more use of the limited natural nonrenewable resources we have on our earth. Recycling will benefit life by reducing our environmental impact, preventing injury, boosting the economy, and extending the use we can make can make out of our resources.
...pollute the Earth with massive waste. Society has the choice between wasting life on working in order to purchase good which contribute to the destruction of the environment or living a ‘full satisfying life’, occasionally scavenging or working your self-sufficiency skills to obtain the necessities for contentment, eliminating waste, and boycotting everything.
Gold was discovered around 6000 BC; it was first discovered in its Natural state un-combined. Gold can be found in the earth’s crust in two different types of deposits: Lode deposits which are deposits in solid rock and placer deposits which are found in stream beds. Aluminium is the 3rd most common element and the most abundant metal. However it was not extracted and used in its pure form until 1825 many years after Gold. Although Aluminium bearing compounds, have been used in pottery, paint and medicines since early civilisations. Aluminium is never found naturally, it is always found combined in a compound or ore. The reason aluminium is always found combined and Gold is found Un-combined is there reactivity. Gold is not very reactive therefore doesn’t reactive with other elements in its environment, however Aluminium is very reactive and reacts with many things within its environment resulting in it always being found combined. The development of both these elements throughout the years between their discovery and now shows us how far human technology has come from not being able to extract aluminium at all, too now Aluminium being the most produced metal on earth and gold becoming one of the most prized elements of all.

Aluminum is among the most typical metals that's utilized in aluminum castings. It's both lightweight, but very study which enables it to operate in several different programs. While you will find concerns of shrinkage and cracks when treating the aluminum casting, following a specific recommendations put by the industry can permit the greatest results.
Recycling is of great importance, and its importance is economic and environmental. It preserves natural resources, reduces depletion, reduces the amount of waste, reduces its growth, conserves the environment, cleanses it of some harmful waste, reduces unemployment and creates opportunities. New work.
By showing the world the severity of our need for conservation, we will be able to save the earth and get the most out of our resources. We need to fix this problem before it becomes uncontrollable to the point of having no resources to supply our needs. By reducing our consumption of resources, we will be able to become closer to fixing the problem of global warming, high gasoline prices and pesticide filled meats. The outcome of respecting our world and “going green” will better how we live our lives, our communities and the environment. The concept of “going green” is a necessity for the future because “our children deserve cities as beautiful as they are.
There are also several long term benefits of recycling. For example, “collecting and processing secondary materials, manufacturing recy...
