Store it in the balls.

Throw it in the trash.

People talk about recycling and that makes a difference for restaurants, but at home quantities? Just put it in the trash.

Dump it in a 5l canister that I call my 'waste oil' canister. When its full, I take it to the recycling plant whenever I'm going there anyway.

Put it on a bottle, and when the bottle is full take it to the used oil recycling bin in my neighborhood.

You should collect it and dispose it at the waste management facility of your city

Put in a plastic bottle and throw that away when it's full. Alternatively there is a powder you can buy to harden the fat so you can chuck it in the trash.

Pour it in my compost with all my non-meat food leftovers.
