We throw veggie scraps into a plastic 5 gallon bucket and haul to the garden when it gets full. I found that collecting rotten tomatoes and other juicy stuff will start to make the bucket pretty smelly, and thus anaerobic. (There's no problem when I put it in the mulch pile, because it is dry anyhow with brown stuff.) So I have to empty it more often when it's wet. I also peel veggies into a sheet of newspaper then wrap it and throw in the mulch pail; this helps keep it aerated and drier. You'd be surprised how strong a double thickness of wet newspaper can be. Enough to get you out to the mulch pail with it , anyhow.
