Many community gardens have a compost bin that the community is welcome to use. Might be worth looking into.

Discussing ways to reduce waste and build community!
Celebrate thrift as a virtue, talk about creative ways to make do, or show off how you reused something!
You could do worms, it's easy to get started and I think low enough smell you could keep them indoors.

Might be a hard sell to the landlord honestly, but I can ask them if that's an option available regardless.
You don't need to inform them...
I posted this eight months ago.
It's just a bin in your kitchen.
With worms though? Wouldn't they see that as a potential pest attractor?
Not if you're doing it right. Worms should eat things before flies have a chance. The air holes are too small for mice or anything.
In my region we get a compost bin from the city. A special dump truck collects it for composting.
However, I have seen people using composters on their rooftop gardens. It kinda looked like a bbq grill, but with a big wheel on one side to flip it. That could be for you, if you have rooftop access.
Unfortunately not, but we do have a community garden on the property grounds. I can try to find someone familiar with it and ask them.
Do you have a balcony?
I freeze my scraps until I have enough to make vegetable or chicken broth/stock, and then after the broth I have a vermipost bin (worm bin) on my balcony. Since I'm in an apartment by myself, this is the easiest way. I give the worm tea and castings to my sister if I'll be visiting her or to the community garden since there's not enough light on my balcony to grow anything. This is my first time living somewhere with winter (I previously lived in warmer climates), so I did need to bring my worms in for the winter so they didn't freeze (of you have extra space in a utility closet that could be a spot), and there was no smell as other had mentioned, as long as you don't overwhelm them the worms do a good job of processing everything in a timely manner. Giving them crushed eggshells and coffee grounds really helps with this as well.
I've known friends that made a countertop sized worm bin with less worms and had no problem with it right in the kitchen of their small apartment.
