In this context, to "light (up)" something means to set it on fire. We can pick up a context clue from the comment about the incinerator, which is a kind of machine used to burn waste at high temperatures until it becomes ash. Ex. A: Are you sure you want to burn all these letters? B: Yes. Light it up!
