How to compost indoors

Indoor composting is a great way to get rid of some of your kitchen waste. It’s an excellent alternative to outdoor composting for those without a garden or for anyone who simply doesn’t need enough compost to justify maintaining a sizeable outdoor compost heap.

Although indoor composting is relatively easy, once you know how to do it, getting started can seem overwhelming. We have compiled a number of indoor composting tips to help you from getting started to troubleshooting problems with your compost.

What to put in your indoor compost bin

Before you begin, it is a good idea to know what you can and cannot put in your compost bin. The items you put in a composter fall into two categories: green and brown matter. In addition, there are some types of kitchen waste that are not suitable for composting.

Green substance

Green matter is food and garden waste. It might not be all green, but it should be vegetable. Green matter includes fruit and vegetable peels and scraps (excluding citrus fruits), coffee grounds, tea leaves, healthy plants, and cooked or uncooked grains, including bread (but only in moderation).

Brown matter

Brown matter is a high carbon material that is also essential for making compost. This includes cardboard, newspaper, paper towels, coffee filters, dry leaves, sawdust, pet fur, and human hair.

What not to put in your compost bin

Never put meat or dairy products in your compost bin, as they may smell bad and attract rodents into your home. Also, avoid composting fats and oils as they will go rancid.

How to compost indoors

Follow these simple steps to start composting indoors. You don’t need a lot, but you should have everything in hand before you start.

Find your compost bin

First of all, you will need a container for composting. Small households of one or two can get by with a 5 gallon container, but larger households and households with lots of kitchen and garden waste to compost should look for a 10 liter container. to 20 gallon containers.

The simplest option is to buy a special composter. However, if you can’t find a suitable option, you can buy a large container with a lid and drill some holes at the top for ventilation.

Start with brown matter

Start by filling your composter about three-quarters full with wetted brown matter (the level will decrease as it starts compacting and composting, so you have room to add more green matter). Check out the brown substance section above to get your own idea of ​​what to use. All pieces of cardboard should be shredded, although you can simply ball up sheets of paper or paper towels.

Add soil

Sprinkle a cup of soil on your brown substance. Experts disagree – some say the soil contains bacteria that start the composting process, while others believe adding soil is not necessary. Ultimately, the soil cannot harm your compost. Just make sure it’s not too wet. If you think your compost is too wet, add absorbent dry matter like sawdust, paper, or cardboard.

Common concerns about indoor composting

My compost is moldy

Mold is perfectly normal in a compost heap. So don’t be alarmed if you see mold. However, you can make sure it isn’t overly wet.

Some substances don’t compose

If you find that some kitchen or garden waste is not breaking, your compost heap may be too dry or lacking in ventilation. To improve ventilation, rotate your compost regularly. To make it less dry, just add some water.

My compost smells like ammonia

This is a sign that your compost does not contain enough carbon. It’s a simple solution – just add more brown substance, like dried leaves or paper.

My compost smells like vinegar or rotten eggs

A vinegar or sulphurous rotten egg smell usually means the pile is either too wet, too compacted, or not adequately ventilated. Rotate the compost to improve aeration and decrease compaction, and add brown matter if it appears too wet.
