It’s easier than you think to learn how to compost in an apartment. Composting can be done anywhere with very few supplies needed.

Indoor composting can make a huge effect on our planet. The average US household produces 650 lbs of organic trash a year, but most of that is landfilled. In fact, 60% of our landfills are full of organic matter. You think it would break down since it’s dumped into a giant hole in the ground, but it doesn’t because landfills aren’t aerated.

It’s called anaerobic decomposition, and all of that oxygen deprived, organic matter now releases methane into the atmosphere.

Methane is 72% more powerful than CO2 which means it’s responsible for hastening climate related issues. You can read more about greenhouse gasses in my post How to Offset Your Carbon Footprint and Why You Should.

Because organic and inorganic materials are mixed together, think your trash bags, plastic, and food scraps it creates a perfect preserved atmosphere.

Think of all the good we can do just by removing organics out of our landfills.

I have a huge guide for backyard composting, but what if you don’t have a backyard? Can you still compost? Of course, you can! 

If there’s only one thing you take away from this blog, I want you to understand the power of composting. Composting is the most effective tools in the zero waste tool belt. 

how to compost in an apartment

While you may have to get creative an indoor compost bin isn’t a nasty item that we should all dread.

As a matter of fact, there’s a misconception that compost is stinky, but it’s not. Compost doesn’t really smell like much at all.

If anything, it’s just slightly earthy. The reason your trash stinks is that you’ve mixed organic materials with non-organics which are preventing the decomposition process.

I’ll break down a few options so you can decide which small compost bin or composting method is perfect for you.

worm composter bin:

A worm composter bin is one of the most common forms of indoor composting.

When it comes to indoor composting, it’s important to keep a good mix of carbon and nitrogen. Carbon is paper, cardboard, newspaper, dry leaves, etc.

Since shredded paper can’t be recycled, it’s a great addition to keep your compost balanced! For more information and recycling tips be sure to check out my blog post How to Recycle Paper the Right Way!

Nitrogen is going to be most of your food scraps, and ideally, you want to aim to keep your compost around 50% carbon and 50% nitrogen.

There are several tutorials online, where you can make your own compost bin or you can buy a worm bin. I have a worm bin 360 that I really liked! I unfortunately kept my worm bin outside and sent 1,000 worms to worm heaven. *May they rest in peace*

Worms like to be kept around room temperature, so they’re the perfect indoor pet that happens to like eating your food scraps. Just don’t add dairy, meat, or citrus peels. 

You can typically find red wigglers, the composting worm, at your local bait shop. 

bokashi indoor composting:

I’m super intrigued by the bokashi indoor compost bin. It seems really simple, almost so simple that it’s too good to be true. It’s a giant bucket and you add all of your compost including meat and dairy into the base.

You mash it all down and then add in an activator mix which is full of microbes which hastens the process of decomposition.

According to the website, you should have compost in 4 weeks. I don’t think you have to keep a balance of nitrogen and carbon, I believe you can only add food scraps and the activator mix takes care of the rest!

trench method:

If you don’t have a yard, this is definitely a reconnaissance mission. Trench composting is where you dig a hole in the ground and bury your compost. It’s really easy, effective, and inexpensive. 

The only problem is finding a place to do it. 

electronic composting:

Yep, they actually make electronic indoor composters that will turn your food scraps into compost overnight! How cool is that?

farmers market:

Most farmers at my farmer’s market have large compost piles. They take odds and ends off the vegetables that people don’t want like carrot tops or radish tops (even though you should 100% be eating those things and check out my post on 8 Innovative ideas to Cook with those Food Scraps) to take back to the farm and compost. 

Ask one of the farmers if you can bring your scraps to add to their pile.

I also have neighbors and friends with chickens who are more than happy to take my scraps off my hands. It certainly doesn’t hurt to ask around and see who could use them. 

community garden:

Community gardens often have compost plots. See if you can join the community garden and add your food scraps to the pile. Who knows, you might make some new friends and collect some delicious produce in the process. 

city wide service:

Check to see if your city offers composting or if there’s a business in town that collects food scraps. Often times someone is out there performing that service, it just takes a little bit of googling. 

My city doesn’t offer municipal compost, but they do subsidize backyard composters for people. All it took was a short google search!

get online: 

There are so many ways to plug into groups and find people with the internet today. If you’re trying to compost, I’m sure there’s someone in your area that has chickens, a composter, or a large garden check out the app ShareWaste.

where do I keep my indoor compost bin?

For indoor composting you definitely want a small compost bin. Place the compost bin in a closet, in your basement, on the counter, or even in a cabinet. Ideally, your indoor composter should be kept in a dry place that is reasonably dark.

can i speed up compost?

Yes, there are several things you can do to speed up your compost. Here are a few tips:

• Keep it warm. Heat will speed up the process tremendously. Cold composts can literally take years to mature properly.
• Add some twigs. Putting some twigs along the bottom of the bin. This will allow air flow and will speed it up.
• Don’t forget to turn it. Stir it frequently to allow more oxygen to get into the compost. I recommend turning it at least once every other day if not more.
• Mix in greens. Grass clippings, manure, and leaves are all great options. Be sure to include them into the soil.

what do i do about maggots?

If you end up with maggots in your small compost bin, don’t stress out! I realize that seeing a bunch of maggots moving around in your compost can be pretty creepy, but it’s a good thing.

They help break down items in the compost and in turn, causes the compost to mature faster. If they are too much for you, you can make some changes and prevent more of them.

Simply add more grass, cardboard, or even shredded paper. This will keep the compost bin drier and not as inviting for the maggots. Additionally, you should add a lid so flies can’t get it in and bury the food so it’s not on top.
