I have an apartment where the dumpster is a car's drive away, and taking trash down involves 4 staircases. What is the best way to ameliorate this situation?

i cannot possibly express how much of a gigantic pain in the ass this is; it's making more more slovenly than i want to be because it's such an inconvenience to throw stuff away.

like should i buy a hand truck? that wouldn't help for garbage bags
