Eccentrics with empty tins for scraps (8)
I believe the answer is:
oddments
'scraps' is the definition.
('oddment' can be a synonym of 'scrap')
'eccentrics with empty tins' is the wordplay.
'eccentrics' becomes 'odd men' (eccentric or odd people).
'with' means one lot of letters go next to another.
'empty' means to remove the middle letters.
'tins' with its middle removed is 'ts'.
'oddmen'+'ts'='ODDMENTS'
'for' is the link.
(Other definitions for oddments that I've seen before include "Motley assortment of things" , "just a few items" , "Assorted leftovers" , "Remnants" , "Bits and bobs" .)
