Computer programs for waste removing (8)
I believe the answer is:
software
'computer programs' is the definition.
(I've seen this before)
'for waste removing' is the wordplay.
'removing' indicates an anagram (moving the letters again).
'for'+'waste'='forwaste'
'forwaste' is an anagram of 'SOFTWARE'.
(Other definitions for software that I've seen before include "Computer programs, etc" , "PC requirement" , "Programs that drive computer, not hard" , "Computer programs and accessories" , "Computer stuff" .)
