Start, for example, in waste container (5)
I believe the answer is:
begin
'start' is the definition.
(I know that start is a more specific form of begin)
'example in waste container' is the wordplay.
'example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'in' is an insertion indicator.
'waste container' becomes 'bin' (rubbish bin).
'eg' put inside 'bin' is 'BEGIN'.
'for' is the link.
(Other definitions for begin that I've seen before include "Launch" , "Found" , "Israeli statesman" , "Clandestine, furtive" , "Israeli prime minister who shared the Nobel Peace Prize with President Sadat" .)
