The easiest thing to do would be just dump everything in the alley. Thats what all city people do. They are stuffed w/garbage anyway. A friend of mine dumps all his trash around the city alleys. And its nothing incrimminating either. If you live in the woods then you have enough privacy to do whatever, burn, compost, bury. If you live in the city its much harder to get rid of incrimminating trash. City people don't have the options the people who live in the woods do. But letting everything dry out like somebody said above sounds like the best bet. Once everything is dry you could crumble into basically dusts and then it would be much easier to get rid of.
