Utopia Kitchen Compost Bin for Kitchen Countertop

While you can collect scraps in almost any old container, if you don’t empty it on a regular basis, your bin will begin to stink. The Utopia Kitchen Compost Bin has a charcoal filter that must be soaked in warm, soapy water, cleaned, and sun-dried weekly for best odor control and eventually replaced when worn (a spare is included).

In the absence of stinky compost, there’s no need to hide your bin, making it easier to use and more likely to become a permanent fixture in your kitchen.

We discovered that in a two-person family that consumes enormous amounts of fruits, veggies, and coffee grounds, the 1.3-gallon bin took around one week to fill. A larger household may need to empty the pail once every few days, moving the contents to a larger outdoor compost pile or allowing the contents to run their course before using the little yield for plant soil.


  • Design that is both appealing and long-lasting
  • It will not rust
  • The charcoal filter absorbs odors
  • With one hand, remove the lid


  • Steel is easily smudged

FoodCycler FC-50 by Vitamix

If you’re looking for a countertop composter, another alternative is a food recycler. This machine electronically converts garbage into a reduced mixture that may be put to a worm bin or outdoor composter by using heat and a grinder.

It’s especially beneficial for food wastes that take a long time to degrade in standard worm bins or compost piles, such as bones and eggshells, or items that produce aromas or attract pests, such as meat and dairy products.

Keep in mind that because the machine employs heat in its operations, there may be a minor odor while the unit is in use. The majority of individuals describe it as just the scent of cooked food and do not find it particularly irritating.

When the cycle is over, the resulting product is fine enough to add to your garden or to a composter for additional processing. This is a more expensive choice than standard indoor compost bins, but it eliminates concerns about a compost bin sitting for an extended period of time with food scraps inside that may generate odors or attract flies and rats.


  • Energy consumption is minimal
  • There is no odor
  • The operation is quiet


  • Expensive
  • Must be plugged in

Composting’s History

Composting has been used for a long time; in 1905, Sir Albert Howard developed the notion of churning dirt together during decomposition, resulting in the Indore technique of composting, which was only the first step.

In 1924, Rudolph Steiner advocated composting as a good way for farmers and gardeners alike to enhance crop growth. Several composting methods were established through exploration and trial and error.

The first was the Indore method, which involved turning five-foot mounds of compost every six to twelve weeks. This is the most fundamental method of composting, but it still works effectively today.

The University of California Approach, invented by Dr. Gloueke, is very similar to the Indore method, but on a smaller, speedier scale. Because of the heat, decomposition occurs more quickly in California, so turning more frequently is required.

The third and last way is the biodynamic method, which is the most widely used today. It uses composting tumblers, the elevated bin method, compost in a bag, and several more forms to make up the most commonly used compost methods to date.

Composting is an essential process in the ecosystem; the breakdown of plant matter is crucial to living species that can directly benefit from the compost, utilising it for nutrients as they thrive and grow. All of this is facilitated by the use of a fantastic composting grinder, such as the ones in this best composting grinder list.

Buyer’s Guide for Composting Grinder

Composting has been around for a long time and works well for cruciferous vegetables and any other sort of food you want to cultivate. You may also give your houseplants a nutrient boost by adding compost. But, while looking for a composting grinder, what should you look for? There are a few critical considerations listed below.


The size of your composting grinder is one of the first things you should think about. Everything from little tabletop units to gigantic outdoor versions is available. Consider how many plants or how much area you need to cover with compost, as well as how frequently you intend to add it to the soil.

This should give you a decent notion of the size. The idea is to choose one that isn’t too enormous and takes up too much space while still being large enough to suit your composting requirements. Remember that composting can take weeks. So you want to gather enough to cover all of your bases in one shot.


Compost need wind to break down, and many typical arrangements do not provide it. Because air helps compost break down faster and more evenly, you should have enough air openings to accommodate the size of your compost machine.

Many larger units include an aeration bar inside the setup, which works well because it makes it more difficult for pests or odors to enter and exit. Others include small screened areas on the sides or end of the grinder that allow air to enter while keeping the compost within.


Some of these devices are pre-assembled and ready to use, while others require assembly before use. If you’re handy with tools and a do-it-yourselfer, putting it together shouldn’t be too difficult.

However, if you aren’t, you should consider what you’ll need to do to get it up and running. Check to see if it comes with all of the necessary pieces and tools, or if you’ll need to purchase extra items before you can put it together.

The assembling process for these machines is normally pretty simple, but you don’t want to waste time on it. Play to your strengths and decide if a completely assembled or partially assembled product is ideal for you.

Loading and Unloading 

You’ll have to load and unload your compost, and the doors will have a huge impact on how long this takes. Big doors that allow you to easily add large volumes of compost to the grinder without spilling it are ideal. The grinder’s height is also vital since it should be tall enough to fit a bucket underneath to catch any compost that falls out. The doors should be locked between uses to prevent spills.


Take special note of the materials utilized to construct your composting grinder. This is especially vital if the event will take place outside. The body of your product should be made of a strong plastic with a UV coating.

The frame should be made of stainless steel or steel with a powder coating to withstand rust and corrosion. Each item that moves a lot, such as the hinges on the doors, should be particularly durable. For larger composting grinders, recycled plastic is popular.

Chambers: Single or Dual

Smaller grinders simply feature a single compost chamber, which is fine if you don’t have a lot of room to cover. A dual chambered grinder, on the other hand, allows you to keep two batches of compost working at the same time. One side can be a finished compost, while the other is just getting started. Each chamber has an entry and exit point, which you alternate between as you empty and refill it.

Time required for processing

The processing time is the next key factor to consider when purchasing a composting grinder. I assumed you wouldn’t want to buy anything that would take decades to compost. Consider purchasing one with a quick processing time.

Simple transportation

What I mean by this characteristic is that you will need to get a composting grinder that can be moved from one location to another. Don’t get a heavy one that you can’t or won’t be able to move. However, if you intend to prepare compost for little plants, this is suggested. However, if you plan to feed multiple acres of land, you will not need to consider this aspect.

Compost Bin Types


Compost bins begin simply: a bucket that can hold waste until they are disposed of, either in your own compost pile or elsewhere that can be picked up and processed. These countertop compost bins are typically pretty simple, with an easily removable cover, a handle for transporting, and sometimes some ventilation holes. This is what you’ll most likely get if you only need a place to store food leftovers in your kitchen.

Food Recyclers 

From there, compost bins can get even more opulent. Food recyclers may crush and heat food, considerably speeding up the composting process. While a food recycler may break down food in as little as eight hours, it has certain disadvantages.

Because the broken-down food lacks microorganisms, it cannot be utilized as compost right away and must be left outside to decompose further. Food recyclers can also break down considerably more forms of food waste, such as dairy and bones, that household compost piles normally cannot break down on their own due to insufficient heat.

Composting Worms

Worm composters should also be kept indoors because worms require a moderate environment. The design of vermicomposting bins varies, but most allow worms to travel upward and leave rich compost for you below. This can happen with trays or other devices that allow you to access the bin’s lowest level to obtain your worm castings.


Bokashi is a less prevalent type of composting that takes place in an anaerobic atmosphere. These containers have tight-fitting lids that allow your garbage to ferment. The fermented material that results cannot be used as much as regular compost and must either degrade further in a compost bin or be buried. Bokashi is appealing to those with limited outdoor area, but the material’s applications are limited.


How much upkeep is necessary for compost bins?

Kitchen compost containers can endure indefinitely if properly cared for. Typically, this entails washing them out after emptying them, either by hand or in the dishwasher.

If you purchase a bin that requires liners, as some do, you must also ensure that you maintain those stocked. If you are composting with your bins, you may also get tools to measure the pH of the soil, as well as its temperature and moisture levels.

Worm bins require significantly more upkeep, and worms might feel like a cross between a pet and a household duty. In addition to caring for the worms, you must ensure that the worm bins are well-maintained and in the proper location for the worms to grow. Vermicomposting isn’t rocket science, but it might be intimidating for newcomers.

What is the ideal location for a compost bin?

Storing your compost collection bin is a critical decision for the effectiveness of your composting system. If you keep it out of the way and make collecting scraps too difficult for you and your family, scrap collection may not become a habit. If you put a stinky container in your kitchen that you don’t like the look of, it might not survive long since you’ll get tired of seeing and smelling it.

The size of your bin and kitchen play a factor as well, since some larger bins, such as worm composting solutions, may be too large to store on a countertop. Similarly, even if the bin is compact, smaller kitchens may not wish to save the room.

If you want to keep your bin concealed yet accessible, placing it beneath the sink is a good option for those that are tiny enough to fit. You can also use a pantry or closet if it is close enough to the kitchen that going to it with your scraps does not need a special trip.

Try placing one of the appealing solutions we mentioned above on your countertop. Scraps will be more likely to be used here because they will have a shorter distance to travel. When shopping for countertop bins, look for one that offers odor control.

What should you put in your compost?

Fruit and vegetable scraps constitute the majority of any scrap collection regimen. Aside from that essential ingredient, it’s a good idea to examine the recommendations for your unique compost bin and compost system.

Worm composters, for example, restrict the use of too much coffee, citrus, and other elements that can make the worms’ soil overly acidic. The Vitamix FoodCycler FC-50 (available on Amazon) can break down nut shells, eggshells, and even bones, but the brand warns against using too many sweet fruits in one batch since they can caramelize and bind the machine as it warms and grinds.

What shouldn’t you put in your compost?

You should never compost fish, meat, eggs, or dairy products. Avoid using coal, charcoal ash, diseased or insect-infested plants, fats, and oil-based materials. These materials are devoid of vitamins and minerals.

Furthermore, when decomposed, these compounds are detrimental to the environment. They will soon degrade the soil. After decomposing these materials, the earth will receive no nutrients.

Furthermore, the soil will expend all of its energy digesting these contaminants, resulting in a total waste. As a result, avoid putting these types of products in a compost bin.

When will my compost be ready for use?

It depends on what it’s going to be used for, but it should have a lovely earthy smell when it’s been broken down to the point where it’s dark and crumbly.

How can I get started if I’ve never created compost before?

It’s actually fairly simple; all you need are some scraps of compostable materials, such as veggies or leaves, and a place to pile them. It’s also a good idea to have something to toss the pile with, such as a shovel or pitchfork. It truly is that simple to compost.

What do I do during the winter?

That depends on whether or not your compost freezes. If you live in a region that does not freeze in the winter, you will need to maintain churning your compost since it will continue to decompose. If you do freeze in the winter, you can keep your compost pile running, but it won’t start breaking down again until the weather warms up.

Why does my compost stink?

If your compost stinks, it could be a combination of several problems. Your pile could be excessively wet, have insufficient air for circulation, or contain far too much nitrogen.

It might also smell unpleasant because it’s really a pile of decomposition, but the previous three options are just as valid and likely to produce a problem. These issues can be solved by adding dry materials, flipping the pile over, and adding brown materials, in that order.

What should I do if my compost attracts critters?

A well-managed compost pile rarely draws curious animals; one possibility is that you haven’t been caring for the pile as much as you should. Another possibility is that you put something you shouldn’t have in the pile, such as meat or animal fat. No matter how frequently you turn it, this will draw animals to your pile.

Is it necessary for me to have a compost bin in order to compost?

No, you don’t need a container of any type; both the Indore and University of California procedures are done outside without a bin; granted, it’s a good idea to have a separate location for composting, but you don’t need much more than a pile on the ground to get started.

How frequently should I turn my pile?

That is dependent on when you intend to use it; if you intend to use it soon, turn frequently. On the other hand, if you have plenty of time, don’t worry about turning it as frequently; 6 to 12 weeks is the minimum need, but you can turn it as frequently as you need to.

When selecting when to flip your pile, you should also consider the heat, temperature, and other elements. You might also use one of our recommendations for the best composting grinders.

Is it possible to turn compost too much?

It is not advisable to turn your compost on a regular basis. I propose that you turn your compost on a regular basis.

What if you don’t turn your compost?

The composting process can be slowed if you do not turn your compost on a regular basis. The compost will not develop heat, and air will not flow through it, resulting in inadequate aeration.

Is it necessary to crush my compost?

Grinding food scraps for compost before adding them to the bin increases surface area, allowing for faster decomposition. Grinding is particularly necessary for composting fruit peels and cardboard.

How does one go about grinding compost?

A compost grinder can be used to mill your compost. All you have to do now is wait for your compost to cure. You can add the compost whole or in batches, depending on the size of your grinder and compost. However, if you use a compost bin, such as a Miracle-gro or a Vitamix foodcycler, you won’t need to grind the compost because it will be finely ground during the composting process.

Can I mix my compost?

Yes, you can mix your compost if you want. Blending increases the surface area of the compost, allowing the nutrients in the compost to be easily absorbed by the plants’ roots and made available to the plants’ tissues.

Do you put water in your compost bin?

You don’t need to add water to your compost if you add your greens and browns in the proper proportions. However, if you added a lot of browns, the compost may need to be watered down.

Is there a separate compost bin for culinary waste and plant waste?

No, the compost bin does not segregate culinary waste from newly planted plants. However, there are some compost bins that have various shovels or drawers that are separate from the drawers that hold the plant materials.

These drawers are also removable, so you can use any of them depending on your needs. If you’re seeking for bins with separate drawers, go no further than the options described above.

Is it okay to ground rotten fruit in my compost grinder?

Yes, moldy food, veggies, or both can be added to your compost grinder. These moldy materials are primarily disposed of in a backyard composting bin. Mold cells are just another sort of microbe that is nutrient-rich. These mold cells will be in charge of garbage decomposition. They will transform the soil into one that is nutrient-rich and fertile.

What would happen if you left the compost for an extended period of time?

If you didn’t leave the compost for too long and it’s in a dry spot, it’ll be fine. If it is kept outside and not covered from sunlight and rain, it will decay gradually but lose its quality and rich nutrients. Even if you add this Compost into the soil to make it fertile, it will not help the soil grow fertile.

It will also lose all of its nutrients, causing the soil to lose nutrients as well, resulting in a total waste. So, put it somewhere safe so that the quality does not deteriorate.

Are orange peels compostable?

The answer to this question is, of course, yes! Orange peels can be added to the compost to make it more nutritious. Furthermore, citrus peels can be added to increase the value of the compost. Citrus and orange peels are high in nitrogen.

They can readily encourage the growth of bacteria and microbes in the soil, thereby making it fruitful. These are suitable green materials that, when degraded, will provide value to the soil.


Finding the best composting grinder is a difficult task, and there are numerous composters available. There are numerous composting solutions available, ranging from those that live in your kitchen to those that tumble in your garden.

Do you need a small, easy-to-use kitchen grinder? Or do you require a larger, more robust garden composter? In any case, you’re likely to discover the composter you need on our list to make your backyard look just how you want it to.

If you can’t find one, you can look at some of the other composting options in the education section above. Again, you are not required to compost with these composters. They do, however, usually function quite well when it comes to breaking down plant material for your own purposes.

The most crucial aspect is to select a composter that is appropriate for your needs. From little kitchen composters to huge outdoor composters, you’re sure to find an excellent composter for your needs on this list.
