Best Indoor System – Bokashi Living Starter Kit

Best Overall
Bokashi Living Starter Kit
Bokashi Living Starter Kit
A starter kit that has everything you need to be successful in your Bokashi composting journey.

It is no secret that I am a huge fan of Bokashi composting. I have written many times about my favorite Bokashi buckets.

Bokashi relies on fermentation to break food down. You do this by tossing your food scraps and some special bran (full of good and hard-working bacteria) into a bucket. When the bucket is full the fermented scraps need to be buried in the garden or added to a traditional bin for final decomposition.

Bokashi is great for those without a garden as it is a tightly sealed system that can live in your kitchen bench or pantry. Even as someone with a garden, I love this method as it makes composting process much faster.

Bokashi Living Starter Kit is an all-you-need kind of kit! Everything you need to be successful with Bokashi is there: two bins that you can alternate and two packs of Bokashi bran – which you add to your food scraps to get the breakdown going. 

The lid is incredibly tight which is a key feature for an anaerobic system that relies on the lack of oxygen. No airflow also means no bad smells and no sneaky insects inside the bin!

Method used: Bokashi is a fermentation method, but further decomposition is required either through burying your fermented waste or by adding it to a traditional compost bin

What to Consider When Buying a Compost Bin

Indoor vs Outdoor

First, consider what you’ll be composting and where you want your bin. If you want to focus on yard and garden materials, composting outside will be the most convenient. But if you’re focusing on composting food and kitchen scraps, a small and easily accessible indoor bin is the answer.

Having a smaller bin will stop odors from developing since you’ll be emptying it more often. If you want to store your food waste before taking it to a larger outdoor compost pile, an under-sink or countertop bin is your best option.

If you don’t want to have to keep emptying the bin frequently, an outdoor bin may be a better choice for you. If you opt for outdoor composting, consider the location as well. Stationary bins can be placed in the sun or a shaded spot, depending on how quickly you want your compost to be finished.

The heat from the sun increases the temperature, so the waste materials break down faster. Small bins or tumblers can be moved to wherever you want.

Material

Compost bins are typically made from wood, metal, or plastic. Keep in mind that if you’re going to compost outdoors, your bin will need to be weather-resistant. Metal is an ideal choice as it can withstand all seasons and it offers good protection against pests.

Plastic is very lightweight and works well outside or inside, but harsh weather could cause it to warp or crack. Wood can work well in outdoor spaces, but it can rot easily if it’s not looked after properly.

Dark materials are better for absorbing heat and helping your waste materials to break down quickly, meaning your compost will be ready sooner.

Odor

Compost bins that have well-fitting lids will ensure that any odors are contained. This is especially important for indoor composting but it can be a good thing for outdoors as well. A tight lid will also prevent curious pests and rodents from getting into your compost heap.

But your bin must also be easy to open. This is especially true with a tumbling bin. It should have a lid that is easy to open and that doesn’t just rotate when you try to open it.

A compost heap that has been properly mixed will have little to no odor. Ensuring that you add the right amount of brown and green materials will stop the pile from producing unpleasant smells.

The best compost bin will have holes or air vents so it provides effective ventilation. Many indoor bins even have filters to combat nasty odors. Look for bins with removable filters that can be replaced or washed. If the purchase includes replacement filters then that’s even better!

Tumbling vs Stationary

You generally have a choice between two varieties of compost bins: tumbling and stationary.

Stationary Bins

These usually have a bigger capacity than tumbling bins and are the ideal choice for those who have large amounts of yard waste such as grass clippings, weeds, and leaves. To help your pile cook better, you’ll need to mix it manually with a pitchfork every few days.

Tumbling Bins

These are sealed bins that rotate to mix the materials, saving you from having to use your hands or garden tools. They feature elevated designs and usually have handles, which make mixing the materials super easy.

Although they’re usually smaller than their stationary counterparts, tumbling containers are becoming popular thanks to their efficient designs, which help the waste decompose much quicker.

Which type of bin you choose depends on how much waste you want to compost and how quickly you want it to be ready. If you have lots of yard waste and you don’t mind turning the compost by hand every 2 or 3 days, a stationary bin would be a great choice for you.

But if you need your compost fast and you don’t have time for any manual turning, a tumbling container will be your best friend!

Capacity

When it comes to your new compost bin, bigger doesn’t automatically mean better. Smaller bins tend to have 1-10 gallon capacities, medium bins come in at around 11-29 gallons, and the bigger bins are typically anything over 30 gallons.

If you have a large amount of yard waste to add, a small bin won’t be any good to you. On the other hand, it’s important to turn your compost to aerate it and ensure the materials are well distributed, and this can be tricky with a huge bin.

Not only that but the bigger the bin, the longer your compost will have to “cook” to be ready to use. Consider how much waste you have when deciding on the size of your bin.

Features

Next, consider the features that you want your new compost bin to have. Even a simple bin can have features that will make life easier. For example, having a bin with a lid that’s easy to remove means you can just throw food scraps into it as you prepare the food.

A carry handle means you can take the bin outdoors and air vents provide ventilation, reducing odors. Many bins can also hold biodegradable liners so you can bag the compost up.

Specially designed worm bins tend to have more features because the composting process will happen inside them. Worm composting bins usually have tray systems that allow the worms to move up toward the newly added waste.

If you want to start worm composting, be sure to choose a bin with features that give you easy access to the ready-to-use compost.

Worm vs Conventional

Before you settle on a compost bin, decide if you want to use conventional composting methods or vermicomposting (also known as worm composting). Both of these methods will create rich, healthy compost, but which one is right for you depends on your lifestyle and how much space you have.

Conventional composting consists of mixing organic waste of 30 parts carbon, and 1 part nitrogen. In this moist, warm environment, microbes such as Actinomycetes, fungi, and bacteria transform the mixture into ready-to-use compost.

Worm composting involves using red wiggler worms to eat the organic materials and create compost in the form of worm manure. This is an incredibly fertile and rich compost full of phosphorous, nitrogen, and many other micronutrients.

The worms help keep the compost well mixed and aerated, so there’s no extra manual work needed other than feeding the worms and adding paper bedding.

Frequently Asked Questions

What is the best compost bin on the market?

A tumbling composter might be better compared to others. The easy rotating design keeps your compost aerated and well mixed, helping it to decompose much quicker. This is perfect for those who don’t have the time to spend manually mixing and turning their compost.

But which bin is the best for you completely depends on your lifestyle and how much time and space you have. If you don’t have access to a garden or backyard, a good stationary kitchen compost bin with odor control technology is your best option.

How do compost bins work?

The composting process involves the activity of micro-organisms in the ground. They utilize the carbon-rich kitchen scraps and break them down. This results in fiber and potassium-rich compost that you can add to your garden soil.

To do an effective job, these micro-organisms need LOTS of oxygen, which you can provide by turning and mixing the compost materials in a compost bin. A compost bin also helps deter pests and rodents from getting into your heap, which is what would probably happen with an open compost pile.

What can be put into countertop compost bins?

Most kitchen waste can be put into a countertop compost bin, including fruit and vegetable scraps, coffee grounds, and crushed eggshells. DO NOT add anything such as meat, dairy products, or pet feces, as these will create horrid smells.

It’s also best to avoid adding any bioplastics to your kitchen compost bin, even if they’re marked as biodegradable.

What can be put into an outdoor composting bin?

Most organic materials can be put into a compost heap including grass cuttings, disease-free yard scraps, leaves, and sawdust. You can also add vegetarian animal manure such as horses, cows, hamsters, and rabbits.
