Composting is a great way to reduce waste, enrich soil, and contribute to a healthier environment. Though many associate composting with large gardens and the countryside, urban composting is becoming increasingly popular as city dwellers seek out sustainable ways to manage their organic waste. This guide will walk you through the essentials of composting in the city, so you can start your composting journey no matter how small your living space is.

Why Should I Compost in Town?

Cities and towns generate immense amounts of organic waste, which mostly goes into landfills and produces foul methane gas during decomposition. Through composting, you will be able to:

Composting Reduces Landfill Waste: Diverting organic waste from landfills minimizes the emission of greenhouse gas.

Enriches Soil: Compost is one nutrient-rich material which can enhance the quality of urban greenery, potted plants, or community gardens.

Save Money: Composting eliminates the usage of chemical fertilizers and soil conditioners.

Promote Sustainability: It’s an excellent way to practice eco-friendly living and inspire others in your community.

Types of Urban Composting Systems

1. Bokashi Composting

Bokashi composting is a fermentation process that uses a special bran inoculated with beneficial microbes. This method is perfect for small spaces as it doesn’t require aeration and produces minimal odor.

Working Principles: Organic material is placed upon Bokashi bran and sealed in a container. During the two week fermentation period the resulting pre-compost can be mixed into soil, or added directly to a general compost pile.

Advantages: Compact, with no odours, and this method can include all organic residues, including those containing meat or dairy.

Disadvantages: An additional cost when purchasing Bokashi bran is essential.

2. Vermicomposting

Vermicomposting is decomposition of organic residues by worms leaving high-quality castings.

How It Works: Red wiggler worms are kept in a bin with bedding material. Food scraps are provided and break down with the aid of the worms into compost.

Benefits: This results in quality compost and can be done indoors.

Drawbacks: Needs frequent monitoring and is not for those who do not appreciate worms.

3. Community Composting

Most cities have their community composting programs where residents can take their organic wastes to designated locations.

How It Works: You amass your food waste and bring it to a community site where it’s composted.

Pros: You don’t have to have your own composting setup.

Cons: You’ll need a local program and regular trips to a drop-off location.

4. Electric Composters

Composters that are placed on countertops use heat and grinding action to speed up decomposition.

How It Works: Organic waste is placed in the machine, which processes it into compost within hours or days.

Pros: Quick, compact, and odor-free.

Cons: Expensive and energy-dependent.

Setting Up Your Urban Composting System

Step 1: Choose the Right System

Determine the appropriateness of the method considering your living space, budget, and goals related to composting. For apartment dwellers with limited space, Bokashi or electric composter would probably be best, while those with access to a balcony or outdoor area may consider vermicomposting or a very small traditional bin.

Step 2: Getting Started

To start Bokashi, one needs an airtight container, Bokashi bran, and organic matter.

For vermicomposting, you will require a worm bin, bedding (shredded newspaper or coconut coir) and red wiggler worms.

For Traditional Composting: Compost bin or pile, organic waste, and a mix of green (nitrogen-rich) and brown (carbon-rich) materials.

Step 3: Learn What to Compost

Knowing what can and cannot be composted is essential to prevent odors and pests:

Compostable: Fruit and vegetable scraps, coffee grounds, tea bags, eggshells, and yard waste.

Avoid: Meat, dairy, oily foods, and large amounts of citrus (unless using Bokashi).

Step 4: Find a Suitable Location

For indoor composting, select a well-ventilated area such as under the sink or in a pantry.

For outdoor composting, place the bin on a balcony or patio and ensure it is protected from extreme weather.

Step 5: Maintain Your Compost

Aeration: Turn or mix the compost regularly (except for Bokashi systems).

Moisture: Keep the compost moist but not soggy.

Balance: Maintain a good ratio of greens to browns (about 2:1).

Overcoming Common Challenges

Odor Issues

1. Proper aeration and balance of greens and browns
2. Don’t over-wet

Pests

1. Seal Bokashi or vermicomposting containers
2. Avoid adding meat and dairy products in regular composting

Space

1. Bokashi or electric composters are small-scale systems
2. You can work with neighbors or local community programs

Time

1. Low-maintenance methods are electric composters or community composting programs

Using Your Compost

When your compost is ready, it can be used for:

Houseplants: Mix compost into potting soil to feed the plants.

Community Gardens: Share your compost with local gardens or urban farming programs.

Green Spaces: Use it to enrich public park soil or tree beds.

Balcony Gardens: Give a boost to the health of your potted plants and herbs.

Inspiring Urban Composting Culture

Urban composting is more than a personal activity; it is a movement that inspires communities to practice sustainability. Here’s how you can contribute:

Educate Other People: Share your journey on social media or to the neighbors.

Organize Workshops: Teach others how to effectively compost in small spaces.

Advocate for Policies: Support initiatives that promote composting and reduce waste in your city.

Conclusion

Composting in the city is a rewarding way to reduce waste, enrich soil, and contribute to a sustainable future. With the right tools and mindset, anyone can start composting, no matter how limited their space. By embracing urban composting, you’re not just managing waste—you’re creating a greener, more sustainable urban environment for everyone.
