In this case, "to dump" is a transitive verb. It needs an actor and an object.

Somebody dumped the bags.

In passive voice, The bags were dumped by somebody.

The bags cannot dump themselves.

Those examples are in simple past tense. Yours are in present perfect.

Somebody has dumped the bags.

Hi,
It's clear.

1-subeject+ dump(transative verb) + object.

e.g: The men+ have dumped+ the plastic bags (Active). so ,when the sentence starts with the "object"(in place of the subject), it changes into passive voice.
