Glass Recycling


Glass can be traced back to 3500 BCE in Mesopotamia, and Egypt and the first glass vessels were made about 1500BC. For the next 300 years, the glass industry was increased rapidly and then declined. In Mesopotamia it was revived in the 700BC and in Egypt in the 500's BC. For the next 500 years, Egypt, Syria and the other countries along the eastern coast of the Mediterranean Sea were centres for glass manufacturing. People have been using and reusing glass for thousands of years. As long as 3,000 years ago, Egyptians used glass to make jewellery, cups and other items. Glass is made by melting sand, soda ash and limestone in a fire. It is one of the easiest materials to recycle.

What can be recycled?

  • All types of beverage bottles, beer bottles, alcohol bottles, wine bottles
  • Food jars such as sauce bottles, jam, spice bottles, syrup bottles and mayonnaise bottles,
  • Plain Drinking Glasses


What can NOT be recycled?

  • Ceramic Dishware Cups and Saucers
  • Plate glass (window panes) Mirror Glass
  • Fluorescent Tubes Light Bulbs
  • Windscreens Car Lights
  • Computer and TV screens Laboratory Glass
  • Crockery and cookware Wire Reinforced Glass


Glass Recycling Process

  1. Glass is collected and sorted buy colour and sold to the buy-back centres.
  2. The glass is transported to a processing facility, where it is cleaned and crushed into what is called cullet.
  3. The cullet is brought to a manufacturing plant and mixed with more sand, soda ash and limestone.
  4. The mixture is heated in a furnace and turned into a liquid. The liquid is then poured into moulds and shaped into new products.


How glass is recycled

  • The consumer throws glass into a recycle bin.
  • Glass is taken from the bin and taken to a glass treatment plant.
  • The glass is sorted by colour and washed to remove any impurities.
  • The glass is then crushed and melted, then moulded into new products such as bottles and jars. Or it may be used for alternative purposes such as brick manufacture or decorative uses.
  • The glass is then sent back to the shops ready to be used again.
  • Glass does not degrade through the recycling process, so it can be recycled again and again.



  • Glass is 100% recyclable. Currently 295 879 tons are recovered annually for recycling. The glass is recycled to manufacture new glass containers.
  • Glass is 100% recyclable and can be used again and again.
  • Glass that is thrown away and ends up in landfills will never decompose.
  • The energy saved from recycling one glass bottle can run a 100-watt light bulb for four hours or a compact fluorescent bulb for 20 hours. It also causes 20% less air pollution and 50% less water pollution than when a new bottle is made from raw materials.
  • A cullet (recycled glass) losses no fusion in the melting process. In other words one ton of cullet will generate the ability to remake one ton of bottles. In contrast it takes approximately 1.2 tons virgin batch material to manufacture 1 ton of glass.


Our Process

You begin the recycling process when you set apart your glass from your household garbage and place it into the Green bags we provide to you for our weekly collection. We combine your glass with glass from other households and sell them to a dealer who, because of the volume of material purchased, often operates out of a storage warehouse. The dealer then sells quantities of glass to a user. This is where the actual recycling-manufacturing one product into a new product--takes place.
