How a glass bottle is recycled

We supply a special type of blended, refined blast furnace slag at Blastrite for use within the container glass industry. It’s called Magflux and consists of caO, SiO2, Al2O3 and MgO.

Once added as a refining a product it acts as a reducing agent and helps to prevents defects in glass such as blisters or seeds.

Our furnace slag has been used in the production of countless glass bottles over the years, many of which end up at recycling centres ready to be made into other glass products.

Have you ever wondered how these bottles are recycled though? If so, we’re going to tell you in this blog.  

The life cycle of a glass bottle

Once the bottle is made and filled with a product the consumer buys it, uses and disposes of the glass container, this is where the recycling process begins.

The recycling process is broken down into these steps...

  • Consumer takes the bottle to a househol recycling centre – Empty bottles are tossed into recycling bins. These bins are normally colour coded into brown, green and clear options so the right coloured bottles are tossed into the right bins.
  • Containers are taken to recycling plant – Once the recycling bins are full they are transported to a recycling centre where the reprocess treatment begins.
  • Glass is sorted by colour – Bins are emptied and bottles are checked and sorted into the right colour.
  • Glass is washed – The bottles are washed to remove any impurities ready for the next stage of recycling.
  • Bottles are crushed – The glass is crushed and broken, before being melted and moulded into new glassware.
  • New bottles are formed – New containers are made out of the glass. Sometimes the glass is recycled and made into other glassware or it can also be used for decorative purposes as well.
  • Bottles are filled and used again – Once the glass is made into new containers it’s filled with produce, stacked on shelves and placed on sale.
  • Bottles are used and recycled - The recycling process starts all over again!

The next time you take glass bottles to a recycling centre spare a thought for what happens to them afterwards.
