    Best Overall: FCMP Outdoor IM4000 Tumbling Composter

    Tumbling composters are some of the most popular types of composters, thanks to their ease of use. Instead of needing to get out your pitchfork and manually turn the compost pile, the tumbler design makes it easy to regularly mix the contents of your composter for faster decomposition. The FCMP IM4000 Tumbling Composter is a top option that holds 37 gallons of material and has dual chambers— you can use one to finish a load of compost while you continue to load the other chamber with new material. Alternatively, some users have opted not to install the partition that divides the barrel and use this composter as a single chamber tumbler.  

    Perched on a metal stand more than two feet off the ground, this tumbling composter helps to minimize the chances of rats invading your composting material. However, the sliding plastic doors to the barrel can become frozen shut in winter weather, which has been a complaint of some users. In general, this composter is perfect for the needs of an average family looking to create compost for use in a home garden or to minimize organic waste that would otherwise end up in a landfill.

    Best Small: Miracle-Gro Small Composter

    If you feel like you don’t have enough room for a composter, this version from Miracle-Gro is your perfect solution. This small composter has room for 18.5 gallons of waste but is compact enough to fit on a balcony, patio, or anywhere that has just two feet of space available. It’s also a great choice for a single person with a minimal amount of organic waste to be composted. 

    The Miraclo-Gro Small Composter has a single chamber design. It cures compost in as little as 4 to 6 weeks and only needs to be turned every 1 to 2 days. Just beware that the oxygen holes (which help aerate the organic material for faster decomposition) sometimes allow debris to fall out during mixing. Most users just sweep up the mess after turning, use a garden hose to clean the area or place it in a spot where a little extra compost won’t be an issue (like over dirt or grass).

    Best Stationary: Algreen Stationary Composter

    A stationary composter will quickly become a fixture in your yard and an indispensable part of your gardening routine. This version from Algreen stands 30 inches tall and 25 inches wide but holds up to 96 gallons of compost. A locking lid keeps animals out but makes it easy to add your organic waste to the composter. 

    One feature that users appreciate is the dual sliding doors at the base of the composter that make it easy to access the finished product. Typically, you can expect to have finished compost in as little as 6 to 8 weeks. One reviewer points out that this stationary composter turns out a huge quantity of compost with minimal user-intervention (just occasional churning of the product and adding dirt). Just keep in mind that if you overload the composter without regularly removing finished compost, you may compromise the integrity of the plastic walls and doors.

    Best Budget: Redmon 8000 Compost Bin

    A basic outdoor composter is an easy way to advance your gardening game. The Redmon 8000 compost bin boasts an affordable price tag but has a capacity of 65 gallons. There are generally two types of residential outdoor composters—a tumbler style and a stationary bin like this model. This Redmon model is a stationary bin and while it’s lack of a base makes it more susceptible to rodents or pests (depending on what you put into your composter), reviewers find that it heats up the material inside more quickly and is better for processing larger quantities of material. One common complaint is that the lid of this budget compost bin tends to blow off in the wind, so you may need to secure it.

    Best Single Chamber: Envirocycle Composting Tumbler

    For a composter that is easy to fill and simple to maintain, the Envirocycle Composting Tumbler is a great option for a single chamber composter. Available in either a 17 or 35-gallon drum size, users love how easy it is to assemble this composter. It arrives in two pieces that only requires you to set up the base and place the drum on top. With a single chamber inside, there are no nuts and bolts to connect internally to create an internal partition. The rollers in the base make it easy to rotate the drum regularly to mix the composting materials inside. 

    Another feature that is often mentioned is the fact that 4 drain holes in the base collect the liquid created during the composting process. A spigot on the front of the base makes it easy to drain this ‘compost tea’ that can then be used to fertilize plants and trees. Reviewers have also been impressed with the customer service of Envirocycle and report that the company stands behind its products, even after years of use.

    Best Vermicomposter: Nature’s Factory Worm Factory 360

    If you’re looking for a composter with worms, the Worm Factory 360 from Nature’s Factory is a top option to consider. This expandable worm composter is delivered with 4 trays, which is usually an adequate size for the needs of 1 to 4 people. However, you can expand this vermicomposter to a total of 8 trays for higher volumes of waste. 

    The important thing to remember when composting with worms is that they have specific environment requirements. The composter needs to have sufficient airflow, enough moisture, and the right temperatures. The manufacturer recommends that you keep your worm composter between 40 and 80-degrees Fahrenheit. For many climates, this may mean that you need to bring the composter into the garage or even into the house (such as in a basement) during very cold or very warm months. 

    However, the additional work to maintain a living composter like the Worm Factory is well worth it when you consider the efficiency with which this system can process organic waste. Everything from kitchen scraps to paper waste can be processed by the worms into high-quality compost that will help your plants thrive. 

    Something else to keep in mind when choosing the size of your vermicomposter is how much you’ll be able to ‘feed’ the worms doing your composting work. As Marisa DeDominicis of Earth Matter NY points out, “The more you feed the worms, the more castings you will get. Keep in mind that it will take several months before you see returns.”

    Best for Yard Waste: Geobin Compost Bin

    If you are primarily interested in composting yard waste, the Geobin Composter is a simple solution. This open composter is made of a flexible plastic material that can expand as large as 3.75 feet in diameter. While it arrives tightly rolled, lay out the plastic to flatten before you bend it to your desired size. 

    The advantage of using an open composter like the Geobin is the quick decomposition of the material inside. Most users find this to be an excellent composter for items like leaves, yard clippings, coffee grounds, and other non-food items.

    While it is possible to put food scraps in an open composter, you may have more rodents and pests interested in your pile. But if you need a simple solution for breaking down natural materials from your yard, the Geobin is a great option and gives you the ability to make the bin larger or smaller.

    Best with Crank Handle: Mantis CT02001 ComposTumbler

    Composting tumblers ensure that the organic material you put into your composter is regularly mixed, which helps to assist in the decomposition process. However, large composting tumblers can become heavy to turn, especially for a single individual. To solve this dilemma, look for a composting tumbler with a crank handle, like the Mantis CT02001. 

    This large composter holds up to 88 gallons of material, so you’ll be glad it has a handle to help you turn the barrel regularly. The drum itself is made from galvanized steel, which has been powder-coated with a non-toxic material. However, users report that you are likely to see some rust develop over time. Even still, you can expect to get at least several years of use out of this composter—often up to 5 years and sometimes as many as 10. Many users are so satisfied with the performance and ease of use of this composter that they buy another one to replace it. As one reviewer puts it, “It’s a good, easy-to-use composter, but it isn’t immortal.”

    Best Large Capacity: Lifetime 60058 80-Gallon Compost Tumbler

    Lifetime Composter

     Courtesy of Home Depot

    If you’re looking for a composter that can handle large quantities of organic waste, the 80-gallon Lifetime 60058 Compost Tumbler is up to the challenge. This large capacity composter has space for a high volume of kitchen scraps, yard waste, paper and cardboard, and more. One of the best features of the Lifetime 60058 is the fact that it also features a lid with a large opening that makes it easy to add materials or access the finished compost. 

    Keep in mind, though, that a large composter can also become quite heavy. Reviewers point that you’ll need to use some muscle to turn the tumbler regularly for thorough mixing of the contents inside. Additionally, some users recommend that you reinforce the lid with additional screws to ensure a long life of service even under a heavy load. One common complaint is that this composter leaks liquid during the composting process, but this 'compost tea' can easily be captured in a bucket underneath the composter or you can simply let it drain into the ground below.

What to Look for in a Composter

Type of container Are you looking to make your own compost from food scraps, or do you need a container to temporarily store food waste? The two products are completely different, so think about your needs.

Size The size of your composter affects the amount of material you can store. If you have a small yard and a mulching lawn mower, you might not need a large composter. Another thing to consider is the size of your yard, since you’ll need dedicated space to keep the composter.

Material Plastic composters are affordable and tend to be weather resistant, but, over time, the material can become brittle from sun damage and could eventually crack. Metal composters are heavier but will last longer. For in-home, short-term storage of compostable materials, it’s more about aesthetics — though be aware that plastics can retain odors.
