Recycling

Recycling is the practice of reusing items that would otherwise be discarded as waste. Variations of recycling include upcycling, which involves adding value to an item for reuse, and downcycling, which involves breaking down an item or substance into its component elements to reuse anything that can be salvaged. Precycling, an alternative approach, involves avoiding the acquisition of unnecessary items that would have eventually have to be recycled or dealt with as waste.

In this webquest you will find out about what can you recycle, how it works and why you should recycle.
