For those of you that would like to delve a little deeper into the world of recycling, this section is ideal! There is more detailed information on the recycling of different materials and an interactive discussion forum where you can discuss topics of interest with other recycle-more users!
I'm trying to find out how much energy it takes to make a glass jar from raw materials, and from recycled materials, in order to work out the saving. This is to produce a quiz for children aged 7-11. Help please!

I don't know the exact energy values in kJ - but there is an energy saving of 22% for glass when scrap materials are used instead of virgin materials. Every tonne of recycled glass in a furnace saves 1.2 tonnes of primary raw materials.
