Basics of Composting
The Basics of Composting section offers an insightful look into transforming waste into valuable soil amendments. This process mitigates methane emissions from landfills and enriches gardens across Anchorage, AK.
What Is Composting?
Composting is the natural process of recycling organic matter, such as leaves and food waste, into a valuable organic fertilizer known as compost. It is an aerobic method, meaning it requires oxygen, in which microorganisms break down biodegradable material, resulting in a nutrient-rich soil additive.
Benefits of Composting
Composting has multiple environmental advantages. It reduces the need for chemical fertilizers, enriches soil, helps retain moisture in gardens, suppresses plant diseases, and can aid in reducing methane emissions from landfills by diverting organic waste. Moreover, composting transforms yard trimmings and food scraps—typically viewed as waste—into useful materials to promote healthier gardens.
Composting Essentials
Ingredients: A successful compost pile requires a proper balance of carbon-rich materials (like dried leaves, branches, paper) and nitrogen-rich materials (such as food scraps, coffee grounds, lawn clippings).
Carbon-Rich "Browns" Nitrogen-Rich "Greens" Dried leaves Food waste Branches Coffee grounds Paper Lawn clippings
Size: A pile should be at least 1 cubic yard to maintain the necessary heat for decomposing.
Location: Place your compost pile in a convenient yet well-drained area where it can benefit from partial sunlight.
Maintenance: Regularly turn the pile to aerate and provide oxygen, speeding up the decomposition process.
By mastering these composting essentials, Anchorage residents can reduce their ecological footprint and create a more sustainable environment.
Setting Up Your Compost
When starting a compost system in Anchorage, it is important to carefully select a bin, consider wildlife safety, and maintain a proper balance of compost materials for efficient decomposition.
Choosing the Right Bin
The first step in setting up compost is choosing an appropriate compost bin. In Anchorage, options include store-bought bins or homemade systems. Store-bought bins often come with secure lids and can be easier to manage. For those opting to construct their own, materials should promote good ventilation and drainage. One must ensure that the bin accommodates the balance of "greens" (nitrogen-rich materials like vegetable scraps) and "browns" (carbon-rich materials such as dried leaves and twigs).
Location and Bear Safety
Selecting the right location for a compost bin in Anchorage includes considering bear activity. The bin should be placed away from your home yet convenient for adding waste. It must be secure to prevent attracting bears and other wildlife. Bear-resistant containers or enclosures may be necessary to keep bears out and reduce the risk of encounters.
Balancing Greens and Browns
A healthy compost pile requires a balance between "greens" such as fruit and vegetable scraps, and "browns" like dry leaves, grass clippings, and branches. A general guideline for an effective compost is to maintain a ratio of 1 part green to 3 parts brown. This mixture encourages aeration and provides the right environment for microorganisms to thrive, thereby turning waste into beneficial compost for your garden.
By following these specific guidelines, composting in Anchorage can be a successful and rewarding process.
Composting in Cold Climates
Composting in Anchorage, Alaska, presents unique challenges due to its colder climate, yet techniques for winter composting allow residents to maintain sustainability practices year-round.
Anchorage's Unique Challenges
Anchorage faces cold temperatures and long winters, making composting different from more temperate regions. The decomposition process slows significantly in cold weather, which can deter some people from composting during the winter months. However, Anchorage residents can continue to compost by adjusting their methods to accommodate their environment's constraints. For example, using insulated compost bins can help retain heat, and monitoring the moisture content of the compost pile ensures that it remains active. The city provides resources such as an online guide, Composting 101, to offer help with maintaining the appropriate balance of carbon (such as leaves or branches) and nitrogen materials.
Winter Composting Techniques
In the winter, composters can adapt by employing several effective techniques. Layering browns, such as fallen leaves and paper, with greens like kitchen scraps helps to insulate the pile and sustain microbial activity. One could also add a nitrogen source when the temperature of the pile gets too cool, as suggested by Composting in Alaska. Regularly turning the pile can be more challenging in winter, so some practitioners opt for passive composting, allowing the pile to freeze and then decompose naturally as temperatures rise in the spring. The Municipality of Anchorage's Solid Waste Services provides curbside compost carts to support residents' composting efforts, even in colder months. For materials that cannot be composted at home during winter, such as yard waste, the municipality offers services like the Community Compost stations, which operate seasonally.
Compostable Materials
In Anchorage, composting is a practical way to recycle organic waste into valuable soil amendment. The Municipality of Anchorage promotes different methods and practices to handle various types of compostable materials efficiently.
What Can and Cannot Be Composted
Composting requires a careful balance of materials. In Anchorage, one can compost:
Fruit and vegetable scraps
Coffee grounds and filters
Tea bags
Eggshells
Grass clippings and yard waste
However, not all food scraps are suitable for the compost bin. Materials that cannot be composted in the community facilities include:
Meat, fish, and bones
Dairy products
Fats, grease, and oils
In 2022, the Municipality of Anchorage indicated that no yard trimmings (grass, leaves, small branches, weeds) would be accepted at community compost drop-off sites.
Handling Food Scraps
When handling food scraps for composting, residents should store their scraps indoors before disposal. The Municipality of Anchorage provides a specific strategy for dealing with food waste:
Use a sealed container like a 5-gallon bucket to collect the food scraps.
Only include compostable materials that do not attract pests or cause odor problems.
Once the container is full, it can be taken to a designated community composting facility during its operational hours, which in past seasons ran from May through October, Monday-Saturday from 8 am to 4:30 pm.
For personal composting endeavors, it's recommended to maintain a balance of 'greens' such as fruit and vegetable scraps with 'browns' like leaves and twigs to ensure a healthy composting process.
