Kitchen and garden wastes are mostly compostables, meaning we could let it dry out in the pits, and make fertilizers out of them.
Wastes in the garden are usually dried leaves and extracted plants, or animal manure *poopoo*. These should be composted or buried. If you cant, just make sure you place them in tightly-tied bags.
Kitchen wastes, on the other hand, are left over food, or fruit and vegetable peelings, egg and seafood shells, or fishbones. You could place them in sealsed containers and then ask pig feeders to collect your food wastes, or you could dry them and compost them like garden wastes.
Just a note, plastic and paper bags are not food wastes!!!
