Glass was discovered more than 5,000 years ago, and has been used ever since \u2013 for windows, mirrors, jewellery, and containers of all shapes and sizes. Today, glass bottles and jars are used to package a huge variety of foods and drinks.<\/p>\n\n\n\n

Glass is 100% recyclable<\/a>. It takes less energy to melt recycled glass than to melt new raw materials \u2013 so recycling saves both natural resources and energy. Recycling glass reduces quarrying for new sand supplies. This preserves natural resources and the environment. It also takes less energy to melt recycled glass than to melt new raw materials. So recycling glass also saves energy.<\/p>\n\n\n\n

Glass manufacturers also save energy and raw materials by making bottles and jars lighter. With today’s technology, thinner bottles can be made that are just as strong. These use less glass material than was needed in the past.<\/p>\n\n\n\n

How is glass made?
New glass is made from melted sand, along with other raw materials called soda ash and limestone. These are dug out of the ground, or quarried.<\/p>\n\n\n\n

Colours of recyclable glass<\/h2>\n\n\n\n

Recyclable glass bottles and jars come in three main colours:<\/p>\n\n\n\n

  • Clear<\/li>
  • Green \u2013 blue glass is also included in this category<\/li>
  • Brown \u2013 sometimes called ‘amber’<\/li><\/ul>\n\n\n\n

    Two things decide the colour of the glass:<\/p>\n\n\n\n

    The amount of iron in the sand used to make the glass.
    Different amounts of the other ingredients, soda ash and limestone.
    During recycling, different glass furnaces are used for each colour. So, it is very important to separate the colours. If the colours are mixed, the recycled glass will be discoloured, and unusable.<\/p>\n\n\n\n

    Important<\/strong> – Glass of different colours contain slightly different ingredients and must be recycled separately.<\/p>\n","protected":false},"excerpt":{"rendered":"
