Introduces gangs during scrap (6,2)

I believe the answer is:

brings in

'introduces' is the definition.
('bring in' can be a synonym of 'introduce')

'gangs during scrap' is the wordplay.
'gangs' becomes 'rings' ('ring' can be a synonym of 'gang').
'during' is an insertion indicator.
'scrap' becomes 'bin' (I've seen this in other clues).
'rings' inserted within 'bin' is 'BRINGS IN'.

I've seen this clue in The Independent.
