Litter waste disposal when living in an apartment

Curious if anyone has tips or tricks for throwing out litter waste. I live in an apartment, and the dumpster is a bit of a walk away from my unit (nothing crazy but far enough to be super inconvenient to go out to multiple times a week for cat poo).

I also use the Purina Breeze litter box (link attached for reference) that is meant to use pellet litter and a urine absorbing pad at the bottom. This is relevant because my previous system was having a lockable trashcan right outside my front door (my apartment opens to outside not a hallway) to toss pee pads and poo into and then take the garbage bag to the dumpster when it was close to full.

The issue was that after maybe 3 months of this process, I noticed the trashcan started to leak. It could have been the trash bags I was using but I did t want to risk being the cause for cat piss leaking on to the walkway so I threw out the whole trashcan (it was pretty old anyways).

I’ve seen ads for the litter genie but wasn’t entirely sure how it worked. I’ve also thought maybe I just need a new lockable trashcan but should double up on bags? Any ideas or tricks anyone uses would be super super appreciated, thank you in advanced!!
