2020-6-6By SCA Community Engagement Fellow Hayden Sloan. Aluminum or Aluminium if youre not from the US is an abundant element within Earths surface but getting it out of the ground is an arduous process requiring heavy machinery to plow up acres and acres of land.Fortunately the environmental impact of that process can be somewhat balanced out by post-mining rehabilitation
Polyvinyl Chloride more commonly known as vinyl is very versatile and used in all sorts of products from food packaging to toys to building materials. PVC is one of the most lucrative products of the chemical industry. Its everywhere - and comes with a substantial environmental legacy
Read MoreAluminum oxidation occurs at different rates depending on the type of aluminum the finish and the environment surrounding the aluminum. Aluminum 5052 for example is sometimes called The Hulk of aluminum alloys due to its durability and excellent corrosion resistance. Aluminum 3003 the most widely used of aluminum alloys is also

That in turn lessens the harmful disruption and damage being done to the natural world fewer forests cut down rivers diverted wild animals harmed or displaced and less pollution of water soil and air

It is widely distributed and constitutes approximately 8 percent of the earths surface layer. However aluminum is a very reactive element and is never found as the free metal in nature. It is found combined with other elements most commonly with oxygen silicon and fluorine

In parallel with the aluminum production reaction a quantity of metal made at the cathode dissolves into the electrolyte at the boundary layer at the bathmetal interface and is transported to the reaction one where it is oxidied recognied in the industry as the back reaction by CO 2 gas forming CO gas

The purified dry ore called alumina is aluminium oxide - Al 2 O 3.. The alumina must be molten for electrolysis to work since the ions are not free to move in the solid state. Unfortunately alumina has a high melting point 2040 C
