No kitchen scraps should end up in the landfill. They are much appreciated by a variety of animals, including pigs, rabbits, fish, BSF, worms and poultry. Each scrap, even coffee grinds and eggshells, is food for something.
There's always some leftovers or scraps that come out of the kitchen. This should never be put in the trash. It all acts as a food to something else, whether pigs, rabbits, fish, worms, BSF or even your compost pile.
