Recycling makes sense!Watch video now
When we throw things away - food, old clothes, toys, plastic packaging - we are throwing away the energy that was used to make those things.
And where do they end up - in the rubbish dump, otherwise known as landfill.
If it is possible to cut down this waste by reusing or recycling items we are getting more mileage out of the energy invested in the item.
Now that's SAVING energy!
Cutting down on waste is cutting down on energy use - less energy is less electricity, which means less greenhouse gases and less stress on the planet.
Did you know polystyrene used in packaging can be recycled to make coat hangers, photo frames and lots more?
