Glass<br />
Glass in MSW is found primarily in glass c<strong>on</strong>tainers, although a porti<strong>on</strong> is<br />
found in durable <str<strong>on</strong>g>good</str<strong>on</strong>g>s. The glass c<strong>on</strong>tainers are used for beer <str<strong>on</strong>g>and</str<strong>on</strong>g> soft drinks,<br />
wine <str<strong>on</strong>g>and</str<strong>on</strong>g> liquor, food products, toiletries, <str<strong>on</strong>g>and</str<strong>on</strong>g> a variety of other products.<br />

Aluminum<br />
Aluminum <strong>waste</strong> c<strong>on</strong>sists of industrial scrap, which is a by-product of<br />
aluminum manufacturing processes (“new scrap”), <str<strong>on</strong>g>and</str<strong>on</strong>g> old scrap c<strong>on</strong>sisting of<br />
postc<strong>on</strong>sumer items such as used aluminum beverage cans, window frames,<br />
building siding, <str<strong>on</strong>g>and</str<strong>on</strong>g> foil. Nearly 80% of the aluminum in MSW c<strong>on</strong>sists of used<br />
beverage c<strong>on</strong>tainers.<br />
There are numerous successful community recycling programs for mixed<br />
aluminum scrap <str<strong>on</strong>g>and</str<strong>on</strong>g> aluminum cans. These programs are generally selfsufficient<br />
<str<strong>on</strong>g>and</str<strong>on</strong>g>, in some municipal programs, provide an income to subsidize<br />
other recycling activities (Pfeffer., 1992).<br />
Used aluminum cans are collected in curbside pickup programs, at buy-back<br />
locati<strong>on</strong>s, at recycling centers, <str<strong>on</strong>g>and</str<strong>on</strong>g> by scrap metal dealers. A number of states<br />
have established m<str<strong>on</strong>g>and</str<strong>on</strong>g>atory deposits for beverage c<strong>on</strong>tainers <str<strong>on</strong>g>and</str<strong>on</strong>g> have installed<br />
redempti<strong>on</strong> centers at supermarkets. Cans brought to collecti<strong>on</strong> centers are<br />
processed in a number of ways. (Wastesum.,2010)<br />
Ferrous Materials<br />
Ferrous metals are those c<strong>on</strong>taining ir<strong>on</strong> <str<strong>on</strong>g>and</str<strong>on</strong>g> are used in the manufacture of<br />
c<strong>on</strong>sumer <str<strong>on</strong>g>good</str<strong>on</strong>g>s. C<strong>on</strong>sumer ferrous <strong>waste</strong> includes appliances, automobiles,<br />
food, <str<strong>on</strong>g>and</str<strong>on</strong>g> n<strong>on</strong>food c<strong>on</strong>tainers. Am<strong>on</strong>g all the materials recycled worldwide,<br />
ir<strong>on</strong> <str<strong>on</strong>g>and</str<strong>on</strong>g> steel represent the greatest t<strong>on</strong>nages. Ir<strong>on</strong> has been manufactured for<br />
thous<str<strong>on</strong>g>and</str<strong>on</strong>g>s of years <str<strong>on</strong>g>and</str<strong>on</strong>g> scrap was recycled even in the earliest times of<br />
producti<strong>on</strong>. (ISRI., 1993).
