Stop, that is a glass bottle and all glass bottles and jars should be recycled. There is a recycling bin just up there.

Drag and drop the 3 glass products into the right place.
When the glass arrives at the recycling plant it needs to be sorted from the other materials. This is done by hand as well as with special machines that use magnets, metal detectors or computers that use x-rays or infrared.
Once the glass is separated, it needs to be sorted into the 3 main colours. What are the 3 main colours that glass is sorted into?
Clear, green and blue
Clear, green and brown
Black, green and brown
Clear, purple and brown
Move the laser across all the glass to sort the colours ready for the next stage.
The cullet has arrived at a factory! Sofia and Rushil are trying to figure out what happens next. Have a think – who do you agree with?Click on the person you agree with.
I think its just crushed into a powder to make it look like sand as one ingredient used to make glass is sand.
I think the pieces of glass get heated up to melt it.
We are now going to do a little investigation so you can answer our question about if we are recycling enough glass.
We are going to make glass in 3 ways.
So we can use our results to help answer our question we need to make sure it is a test fair.Which method would be best for a fair test?
Use the same amount of each material in the same furnace.
Use different amounts of each material in the same furnace.
Use different amounts of each material in different furnaces.
Your first step is to measure the amount of energy used for each option.Can you help us push each option into the furnace one at a time?
Fab work! From your results, which option do you think is best for the planet?
Cullet - 3230 MJ.
Raw materials - 4470 MJ.
Cullet and raw materials - 3850 MJ.
Making glass generates CO2, let’s find out if the amount of CO2 released changes depending on what materials are used. Before we find out, make a prediction – which do you think will create the most CO2?
Cullet.
Raw materials.
Mixture or raw materials and cullet.
We have collected the CO2 from when you just melted the materials.
Press the buttons to fill the balloons to see how much CO2 was generated.
Which graph would you use to share your results about the
CO2 emissions?
There are several reasons why factories use recycled cullet.Decide if the statements are true or false.
We now have molten glass. The next steps is for it to be chopped into smaller pieces which are called gobs. Each gob makes a single bottle or jar. Right, it is time to shape the gobs. It only takes 5 seconds to do this!Can you set the timer for us?
The final 2 stages are to inspect and package the bottles.Check the bottles with the magnifying glass to make sure they are ready for filling.
Thanks for encouraging me to recycle earlier as we really do need to recycle all the glass we can to protect our planet.
How much energy do you think is saved when you
recycle a single glass bottle?
Enough energy to have a TV on for 5 minutes.
Enough energy to send a message on a phone.
Enough energy to charge
your phone at least 6 times.
Enough energy to play on a tablet for 10 minutes.
Great work on learning about recycling glass.
You are a true Glass Guardian!
