Cities have a high population density with many buildings and little room for garden settings. Thankfully, city dwellers have the opportunity to start composting with more green innovation. Anyone can begin urban composting, whether they live in the countryside or in a tiny apartment.
Composting is available to you whether you have a garden, access to community gardens, or a small balcony space. No matter where you find yourself, you can make use of food scraps and organic material. By diverting organic materials from landfills, we can contribute to a better and cleaner world. If you’re a city dweller thinking of how to begin utilizing your organic waste, you’ll find answers here.
Composting is the process of recycling organic matter naturally. It entails employing methods to speed up the decomposition of this organic matter. The resulting matter is what we know as compost. This looks like fertile soil.

Contrary to popular belief, composting is available to anyone - whether you live in a rural or urban setting. We know that many cities have recycling programs that aid in diverting old items from landfills. By doing so, we reduce the amount of waste that contributes to the world’s population problem. However, composting is also a significant contributor to diverting waste from landfills.
Every home produces food waste that forms organic material, ranging from fruit and vegetable scraps, eggshells, and grains to tea bags and coffee grounds. When we throw these into our regular waste bin, these food scraps end up in a landfill site.
An accumulation of this food waste from many homes contributes to the emission of the toxic gas methane, which in turn contributes to climate change.

As the name suggests, urban composting simply refers to composting in urban areas such as cities and towns. This suggests that we don’t have to leave composting efforts to those in the countryside. People living in cities should embrace composting to curb the effects of this toxic gas and manage food scraps properly. Plus, it is a great addition to apartment gardening to help keep your plants nourished and healthy.
Gone are the days when you need to rely on a large community bin to toss in your food scraps. You can create a small compost container and compost within your apartment regularly. Here, you can toss in kitchen waste instead of throwing them away in the waste bin.

Composting indoors isn’t as difficult as it may seem. You only need to understand the composting basics and continue to learn from there. If you’re lucky enough to have a garden or yard, you can add yard waste or garden trimmings to your compost pile.
The United States Environmental Protection Agency revealed that 30% of what we throw out is yard waste and food scraps1. These materials take up space in landfills. They also contribute to the release of the potent greenhouse gas, methane. Instead of throwing these out, you can create an urban compost heap or compost bin where you can control the process of decomposition.

Compost heaps with a good balance of nitrogen-rich materials and carbon sources contribute to healthy soil. The resulting organic matter is a form of dark and rich soil that can aid plant growth. You can then add these to your garden to help your plants grow.
If you don’t have a garden, your potted plants can enjoy the benefits of the finished compost. Another great practice is to donate your compost to local farms if you have it in abundance.
We can think of composting as a form of natural recycling. This type requires natural methods instead of going through the artificial recycling process. Every home generates different forms of waste. However, kitchen and food waste are common patterns.
Instead of throwing all these organic materials away, we can put them to good use. Your tea bags, coffee grounds, egg and nutshells, rice, amongst other items, can serve a purpose. The resulting materials can help your open or container garden to enrich the soil.
One of the ways composting in urban areas is useful is in helping homes reduce their waste stream. On a larger scale, it also helps cities and towns reduce the amount of trash they toss out.

Contrary to popular belief, composting doesn’t necessarily contribute to an influx of rodents in cities. There are many ways to ensure your compost pile or bin is rodent-proof within the yard and home. There is also a low-maintenance option such as electric kitchen compost. This helps to prevent odors and rodents. On a larger scale, city compost bins avoid the mess that organic waste creates in trash cans.
Apart from reducing waste, composting also helps us generate natural fertilizer. When we create compost heaps, we also create nutrient-rich materials. These nutrient-rich materials help plants grow - whether in gardens, streets, lawns, or within potted plants.
As a result, we rely less on chemical additives that are not always environmentally friendly. Compost also improves soil structure, prevents nutrient run-off, and increases the soil's moisture-holding capacity.
Urban composting can restore the environment, help plants grow, nourish the soil, and reduce chemical use. It helps to reduce the amount of waste we send to landfill sites.
Indoor composting doesn’t have to be as daunting as you may think. With adequate knowledge, the right ingredients, and a suitable bin, you’re on your way to creating a suitable compost.
First, you need to understand the basic requirements for a healthy compost pile. A good compost pile or bin requires water, air, carbon, and nitrogen. Carbon sources are usually dry materials such as bread, wood shavings, shredded newspaper, pine needles, twigs, and brown plant materials. These are also known as browns or brown waste.
On the other hand, nitrogen sources are moist and fresh ingredients. Green nitrogen-rich materials include leaves, grass clippings, flowers, coffee grounds, fruits, vegetable scraps, and eggshells.
You need a good balance of carbon and nitrogen sources. If you have too many browns, you risk having dry compost. Without enough greens, the compost pile won’t decompose fast. A good carbon-to-nitrogen ratio is 25-30:1. Which is 25 to 30 parts carbon to 1 part nitrogen. If you notice that the greens outweigh the browns, you should add more browns.
Apart from these materials, your urban compost pile also needs enough air and moisture to aid decomposition. With the right amount of water and air, you’ll notice the quick reproduction of organisms that aid decomposition.
Once you understand this, you need to know the suitable materials to compost and how to get started. Some materials make good compost, while you should avoid adding others to your compost heap or bin.
Here are some good organic compost materials to add to a compost heap or bin:
Here are some materials to avoid adding to a compost heap or bin:
The reasons for avoiding these materials vary. Waste products like butter, milk, oils, meat, and fish cause odor problems. Apart from that, they also tend to attract unwanted visitors like insects and rodents. Avoid animal products like meat and fish bones. Items like charcoal, ash, and chemically-treated materials can release harmful substances into the soil. These not only affect the soil but also negatively affect plants.
There’s more than one way to compost at home. You could embrace indoor composting, where you keep a bin in your kitchen or create compost piles in a backyard.
