Upcycling is different from recycling. Both processes involve the use of garbage, or put more politely, ‘discarded objects’. But recycled junk tends to remains just junk only that it’s sorted and then sent somewhere to either be disposed of safely or used to make something else.
That’s not so very different from upcycling except that the upcycled junk is specifically used to create something of higher quality or value than the original material.
