I believe the answer is:

chemical toilet

I'm a little stuck... Click here to teach me more about this clue!

'torn up in portaloo' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'a little comic he' is the wordplay.
'a little comic he' can be anagrammed to 'CHEMICAL TOILET'.
However, I'm unsure how this is indicated.

'found' acts as a link.

Can you help me to learn more?

(Another definition for chemical toilet that I've seen is " A collector of waste matter".)
