1) Enclose it. Kitchen scraps that have been enclosed in a container will help keep the smells from wafting into other rooms.
2) Freeze it. Add your kitchen scraps to a zip-loc bag and freeze it.
3) Fill an egg carton. Egg cartons are great “brown materials’ for the compost heap.
4) Vermiculture. They break everything down and the happier they are, the more they produce.
5) No mess composting. There are two ways to utilize the no mess composting: trench composting and sheet composting.
