Broken lamp recast in waste material (5,5)
I believe the answer is:
scrap metal
'waste material' is the definition.
(I know that scrap metal is a type of rubbish)
'broken lamp recast' is the wordplay.
'broken' is an anagram indicator.
'lamp'+'recast'='lamprecast'
'lamprecast' with letters rearranged gives 'SCRAP-METAL'.
'in' acts as a link.
(Other definitions for scrap metal that I've seen before include "Get rid of gold, for instance" , "Waste material for remelting" , ""Old iron"" , "it's going to be melted down" , "waste that's recyclable" .)
