What is the significance of the title, Trash?

The title is significant because trash serves as a symbol that represents the existence of the children in the novel. As people who grow up in the dumpsite, their lives are difficult to disassociate from the trash they pilfer through, and their lives revolve around what they find and do not find. Trash is how people outside Behala perceive them as well, with the police reminding Raphael that his existence is nothing more than that of a dumpsite boy, while Father Julliard realizes the same thing but still shows compassion.
