Searching for a word or phrase [closed]

I am looking for a word or phrase to express the idea of making one thing into an entirely new, better thing.

To give a little bit of context, this is in reference to recycling and upcycling.

Solution 1:

Repurposing would certainly apply to the context of recycling.

Solution 2:

Perhaps revamp is an appropriate term here. Although not associated with recycling per se it really captures the improvement bit.

Give new and improved form, structure, or appearance to:
an attempt to revamp the museum’s image
(as adjective revamped) a revamped magazine
