The right way to recycle glass.

Did you know!!!

• Glass containers for food and beverages are 100% recyclable, but not with other types of glass. Other kinds of glass, like windows, ovenware, Pyrex, crystal, etc. are manufactured through a different process. If these materials are introduced into the glass container manufacturing process, they can cause problems and defective containers.
• Color sorting makes a difference, too. Glass manufacturers are limited in the amount of mixed color-cullet (called "3 mix") they can use to manufacture new containers. Separating recycled container glass by color allows the industry to ensure that new bottles match the color standards required by glass container customers.

Benefits of Recycling Glass

Did you know!!!

• It takes approximately 1 million years for a glass bottle to break down in a landfill.
• Glass containers save 9 gallons of fuel (oil) for every ton of glass recycled.
• Glass is 100% recyclable and can be recycled endlessly without loss in quality or purity – something no other food and beverage packaging option can claim.

How adding other materials can change the color of the glass.

Did you know!!!

• Other materials can be added to produce different colours or properties. Glass can also be coated, heat-treated, engraved or decorated.
• Color in glass may be obtained by addition of electrically charged ions (or color centers) that are homogeneously distributed, and by precipitation of finely dispersed particles (such as in photo chromic glasses).
• Ordinary soda-lime glass appears colorless to the naked eye when it is thin, although iron(II) oxide (FeO) impurities of up to 0.1 wt%[11] produce a green tint, which can be viewed in thick pieces or with the aid of scientific instruments. 
• Further FeO and Cr2O3 additions may be used for the production of green bottles. 
• Sulfur, together with carbon and iron salts, is used to form iron poly sulfides and produce amber glass ranging from yellowish to almost black.
•  A glass melt can also acquire an amber color from a reducing combustion atmosphere. Manganese dioxide can be added in small amounts to remove the green tint given by iron(II) oxide.

How glass is made?

Did you know!!!

Glass is made by melting together minerals like Silica, Soda Ash , Lime Stone and Cullet at very high temperatures, 2600 to 2800 degrees Fahrenheit .

• Silica is a white or colorless crystalline compound, SiO2, occurring abundantly as quartz, sand, flint, agate, and many other minerals

• Soda ash is the trade name for sodium carbonate, a chemical refined from the mineral trona or sodium-carbonate-bearing brines. It is an essential raw material in glass.

• Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3).

• Cullet is recycled crushed glass. Most glass manufacturers rely on a steady supply of recycled crushed glass to supplement raw materials

What is glass?

Did you know!!

• Glass is a combination of sand and other minerals that are melted together at very high temperatures to form a material that is ideal for a wide range of uses from packaging and construction to fiber optics.
• Glass, structurally, is actually more like a liquid, but at room temperature it is so viscous or ’sticky’ it looks and feels like a solid. At higher temperatures glass gradually becomes softer and more like a liquid. It is this latter property which allows glass to be poured, blown, pressed and molded into such a variety of shapes.
