Understanding Urban Composting


What is urban composting?

Urban composting refers to the process of transforming organic waste into nutrient-rich compost within urban environments, such as apartments, condos, or small backyard spaces. It involves using specific composting methods tailored to suit the unique challenges and constraints of urban living.

The role of compost in sustainable backyard living

Compost acts as a natural fertiliser, enriching the soil with essential nutrients, improving its structure, and promoting healthy plant growth. By utilizing compost in your backyard garden, you not only reduce the need for synthetic fertilizers but also minimize waste that would otherwise end up in landfills.

Why urban composting is different from traditional composting methods

Urban composting presents unique challenges due to limited space, potential odour concerns, and the need for efficient decomposition. It requires innovative techniques and alternative composting systems suited to urban environments, making it distinct from traditional backyard composting.


Getting Started: Setting Up Your Composting Area


Choosing the right location for your composting bin

Select a well-drained area with easy access and sufficient airflow. Consider factors like proximity to your kitchen, sunlight exposure, and odour management when deciding on the placement of your composting bin.

Selecting the right composting bin or system for urban spaces

Explore various composting options, such as compost tumblers, worm bins, or bokashi systems, that are suitable for smaller urban spaces. Each system offers its own advantages and caters to different needs and preferences.

Necessary tools and materials for urban composting

Gather essential tools like a compost thermometer, pitchfork or compost turner, and a compost moisture meter. Additionally, collect organic materials such as kitchen scraps, yard waste, and shredded paper for the composting process.

Composting Basics: What to Compost and What to Avoid


Essential organic materials for composting at home

Include a mix of "green" and "brown" materials in your compost. Greens include fruit and vegetable scraps, coffee grounds, and fresh grass clippings, while browns consist of dried leaves, straw, and shredded cardboard.

Green and brown composting materials: finding the right balance

Achieve a balanced carbon-to-nitrogen ratio by combining greens and browns in appropriate proportions. Aim for roughly equal amounts of both types of materials to ensure efficient decomposition and optimal nutrient content in the compost.

Items to avoid composting in urban environments

It's important to exclude certain items from your compost, such as meat, dairy products, oily foods, and pet waste. These materials can attract pests, emit unpleasant odours, or pose health risks in urban settings.


Building Your Compost Pile or Bin


Layering techniques for efficient composting

Employ a layering method, alternately stacking green and brown materials, to facilitate proper airflow and decomposition. This layering helps create an optimal environment for beneficial microorganisms to break down the organic matter effectively.

Managing moisture levels in your compost pile

Maintain adequate moisture levels in your compost by regularly monitoring and adjusting moisture content. Aim for a damp sponge-like consistency, ensuring that the compost is moist but not waterlogged. Sprinkle water as needed or cover the pile during heavy rainfall to prevent it from becoming too wet.

Monitoring and maintaining proper temperatures

Keep an eye on the temperature of your compost pile, as it indicates the activity of microorganisms responsible for decomposition. Ideally, the pile should reach temperatures between 135°F and 160°F (57°C and 71°C) during the active composting phase. Turn the pile regularly to distribute heat evenly and promote thorough decomposition.

Preparing Compost


Speeding Up the Composting Process


Turning and aerating your compost pile

Regularly turn and aerate your compost pile to enhance oxygen flow and stimulate microbial activity. This helps break down materials faster and prevents the formation of anaerobic conditions, which can lead to unpleasant odours.

Introducing compost activators and accelerators

Boost the decomposition process by incorporating compost activators or accelerators. These can include natural additives like alfalfa meal, compost starters, or even finished compost from a previous batch. They provide a rich source of beneficial microorganisms and enzymes that speed up the breakdown of organic matter.

Balancing carbon-to-nitrogen ratios for faster decomposition

Pay attention to maintaining the right carbon-to-nitrogen ratio in your compost pile. Adjust the proportion of greens and browns as necessary to optimise the microbial activity, ensuring that there is enough nitrogen for the microorganisms to thrive and break down the organic matter efficiently.


Troubleshooting Common Composting Issues


Dealing with foul odours in your compost

Unpleasant odours can arise from imbalanced compost, excess moisture, or the presence of inappropriate materials. Address these issues by adjusting the compost mix, improving aeration, and avoiding items that cause foul odours.

Addressing pests and critters in urban composting

Implement strategies to deter pests and critters from accessing your compost. Use a secure lid or cover, avoid adding attractants like meat or dairy, and consider using wire mesh or fencing around the composting area to prevent unwanted visitors.

Resolving issues with slow or stagnant composting

If your composting process seems sluggish, review the carbon-to-nitrogen ratio, moisture levels, and aeration. Adjust these factors accordingly to create a more favourable environment for decomposition. Consider turning the pile more frequently or incorporating fresh greens to invigorate the composting process.


Harvesting and Using Your Finished Compost


Signs that your compost is ready to be harvested

Look for visual cues like a dark, crumbly texture and an earthy aroma to indicate that your compost is fully decomposed and ready for use. It should resemble rich, nutrient-dense soil that can be easily incorporated into your garden.

Methods for harvesting and storing compost

Collect the finished compost by carefully scooping it out from the bottom or sides of your composting bin. Remove any large un-decomposed materials and transfer the finished compost to storage bins or bags. Keep the finished compost in a cool, dry place until you're ready to utilise it.

Utilising compost in your backyard garden or potted plants

Apply the compost to your garden beds, mix it into potting soil for container plants, or use it as a top dressing for existing plants. The nutrient-rich compost will nourish your plants, improve soil structure, retain moisture, and foster overall plant health.

Composting Alternatives for Small Spaces


Vermicomposting: harnessing the power of worms

Explore the world of vermicomposting by setting up a worm bin. Red worms, such as Eisenia fetida, can efficiently convert kitchen scraps into nutrient-rich worm casting known as vermicompost.

Vermicomposting is an ideal option for small spaces, as it requires minimal setup and can be done indoors. The worms digest the organic matter, leaving behind a high-quality compost that is rich in beneficial microorganisms and nutrients.

Bokashi composting: fermenting kitchen waste effectively

Bokashi composting is a fermentation process that utilises beneficial microorganisms to break down kitchen waste quickly. By adding a bran-based inoculant to airtight containers, you can ferment food scraps, including meat, dairy, and citrus peels, which are typically unsuitable for traditional composting. The resulting pre-compost, known as bokashi, can be buried or further composted to complete the breakdown process.

Compost tea and its benefits for urban gardens

Compost tea is a liquid fertiliser created by steeping compost in water. It provides a concentrated infusion of nutrients and beneficial microorganisms that can be applied directly to plant foliage or soil. Compost tea enhances plant growth, strengthens the immune system of plants, and improves soil health, making it a valuable addition to your urban garden.
