Scrap - can it still be recycled with reduced temperature? (9)
I believe the answer is:
scintilla
'scrap' is the definition.
(thesaurus)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for scintilla that I've seen before include "A tiny bit" , "Tiny hint, trace" , "A spark; a trace" , "suspicion" , "Tiny trace or amount" .)
