Why is it utupaji and not kutupa?

Kutupa is the verb to throw / to dump.

Utupaji is a noun made from that verb, meaning dumping or disposal as an activity or process.

This is very common in Swahili: a verb can become an abstract/action noun.

• kutupa = to dump
• utupaji = dumping / disposal

English does this too:

• to pollute → pollution
• to dispose → disposal

So the sentence uses a noun phrase as the subject, not a bare verb.
