Composting is a natural process in which macro- and micro-organisms break down organic materials such as leaves, grass and vegetable scraps to form a rich, soil-like substance. The resulting compost is a dark, rich, organic material. When added to soil, compost provides nutrients to plants and improves the water-holding capacity of soil.
Roughly 20-30% of the material in a typical landfill, including yard trimmings and kitchen scraps, could have been composted. Backyard composting can reduce the trash waste stream, save thousands in municipal tax dollars on tipping fees, and reduce energy and greenhouse gas emissions associated with putting these materials in the landfill.
Backyard Compost Bins Available For Purchase at City Hall
If you live in the City of Bowie, you can purchase a compost bin, pictured below, for $20 at City Hall. We accept cash or check. You do not need to reserve one, simply come to City Hall during business hours and pick up your bin (allowed 2 per home). The front desk staff will guide you. All sales are final. The bins are bigger than you think so we recommend bringing a truck, van, or SUV. If you need assistance please call. After purchasing, you're ready to begin. Check out our "How To" guide here. If you're not sure if you are in the incorporated limits of the City, visit our address verification tool.
- Choose a 4’x4’x4’ grass or soil area in your yard that is easily accessible put your compost bin OR create a pile. Piles and bins can be used throughout the year, and more than one bin or pile area may be desirable so that a new batch of compost may be started while another is finishing. A good compost pile will consist of 2/3 “browns” and 1/3 “greens.”
- “Greens” are high in nitrogen and are typically soft and wet. They include kitchen scraps (veggie and fruit), coffee grounds, tea bags, fresh leaves, grass clippings, and weeds (not invasive or nuisance, e.g., Poison Ivy, English Ivy, Multiflora Rose, etc.).
- “Browns” are high in carbon and are usually dry. They include paper products (napkins, paper towels, and non-glossy newspaper), dried leaves and flowers, and bedding from small pets such as hamsters.
What Not To Compost in Your Backyard
- Chemically-treated wood products/waste
- Dairy products
- Diseased plants or leaves
- Disposable diapers
- Fatty food waste (no grease)
- Fish or fish bones
- Human or dog/cat waste
- Meat and meat scraps
- Peanut butter
- Plants that have gone to seed
Temperature, moisture, and oxygen are three very important components of composting. Compost should feel warm to the touch except in cold winter months. Composting materials should feel moist but not soggy. If compost feels dry, add more green materials. If compost feels soggy, add more brown materials. Also, ensure that enough oxygen reaches the center of the pile by mixing or turning it regularly. During the summer, the more turning that occurs, the faster the process will occur.
Prevent Odor and Animals
Your compost pile will not produce odor or attract animals as long as you place only appropriate "green" and "brown" materials in it, and you turn compost regularly. The City bins have ventilation built in to prevent this from occurring.
Using Finished Compost
Compost is ready for use when it looks dark and crumbly and none of the starting ingredients are visible. Work it into the top 6 to 9 inches of the yard or garden as a soil amendment/conditioner or apply it as mulch.
