Types of Piles :


· Backyard pile: This option is best for individuals with a large outdoor space in a less urban environment. Find a dry, shady spot near a water source. Once you have started the pile, cover with a tarp to keep moist, and turn over regularly to aerate.

· Compost tumblers: These are ideal for folks living in the city who either do not have the space for a backyard pile or are worried about rats and other unwanted animals. Turn your tumbler regularly to mix and aerate.

· Vermicomposting: For worm composting, you’ll need to find a good container of the right size for your household, enough worms to get the process started, and a source of bedding materials, such as newspaper strips mixed with water with soil on top.” A portable bin to house your worms in is ideal, especially for the disaster-conscious composter. Having a home for your urban resource and being able to move it in an emergency can be beneficial.
