Composting is nature's own recycling system. Leaves, grass, and other organic matter provide a home and food supply for nature's recyclers--bacteria, worms, and other microorganisms. These organisms feed on the plant material, breaking them down, and turning them into a dark, nutrient-rich organic product called compost.
As with recycling, composting is about reducing waste through closing loops. While materials such as paper and aluminum can be reprocessed into 'new' items available for re-use, composting is a natural process that allows for the reprocessing of organic waste. Whether or not you grow your own food, what you eat is the product of a number of inputs including fertilizer (either organic or conventional), sunlight, and water. Food that is consumed, however, is only a portion of the product of those inputs. Waste products, including leftover food scraps as well as unharvested parts of plants and other yard waste, contain valuable nutrients that, through composting, can be turned into fertilizer and close the loop! Compost is a high-quality form of organic fertilizer.
Composting is simple once you learn the basics and anyone can do it. If you do garden, you will find composting to be a valuable source of quality fertilizer for your plants and lawn. If you don't garden, give your compost to a friend who does, or try to find an individual or local community group who may be able to use it in community gardens. Either way, composting provides a fairly simple opportunity to turn potential landfill waste into an environmentally friendly and useful product.
There are a variety of composting options which all accomplish the same task of breaking down organic material into a rich, soil amendment. Composting can be done in bins, piles, tumblers, pits, trenches or through the use of worms, cover crops or sheet composting. Bins and/or tumblers come in a variety of different shapes and forms, and are made from numerous materials including pallets, chicken wire, snow fences, plastics, garbage cans, rain barrels, PVC, old lumber and/or any other material one has access to. Bins are often preferred in urban settings, because they keep compost neat and tucked away while providing heat and moisture retention, but piles are generally easier to access and maintain. Compost tumblers are also available, and these overcome the potential maintenance challenges of bins, but are generally expensive and don't have the benefit of keeping your compost in contact with the ground, which is a source of useful organisms vital in the role or decomposition.

Compost materials are often categorized as either 'greens' which provide Nitrogen or 'browns' which provide Carbon. They are also known as wet and dry materials, respectively. Food scraps, green (as opposed to woody) plants, lawn clippings, and tea bags are all examples of 'greens'; while leaves, straw, and twigs are examples of 'browns'. Manure from herbivorous animals, such as rabbits and chickens makes a great, nitrogenous addition to your pile, especially in winter when it can be used to jump start the process and heat up the pile during the cold months. However, be sure to keep the standard ratios of 1:2, green:brown for best results and the quickest decomposition.
Materials to Add: coffee grounds, corncobs and stalks, eggshells, grass clippings, hair, leaves, peanut shells, vegetable and fruit scraps, sawdust and wood chips, as well as straw and hay.
Materials to Avoid: animal products, oils, invasive or diseased plants, coal and wood ash.
