Let’s take it a step further and make a compost bin for our gardens. We made one for under $40, along with some free supplies.

Composting is the process of breaking down organic matter, like food scraps, into all-natural fertilizer. This is how to start composting.

You could make a static compost bin, but a compost tumbler is better if you don't want another chore.

Place a tray beneath the container to catch the drainage. You can keep the compost pile inside or outside of your apartment, though it should be in a cool spot that gets plenty of sunlight. 2.
