 1. Glass is collected from the bottle
banks and each colour is kept separate. Clear, brown, green and blue glass can all be recycled. Blue glass should be placed in the green bottle bank.
2. The glass is transported to the processing plant where contaminants such as metal caps and plastic sleeves are removed.
3. The glass is then crushed and is now called "cullet". It is ready to be transported to the glass factories.
4. At the glass factory, the cullet is mixed with other raw materials used to
make glass (sand, limestone and soda ash) and fed into a furnace where they are heated to around 1200ºC. The amount of cullet in the furnace
depends on the availability of cullet of the right colour and quality. As much as 70% of cullet is used to make new containers in the UK.
5. The molten glass is moulded into new bottles and jars.
