Forget about mixing your compost with a shovel. The best compost cups make the process faster, easier, and more thorough. While this is a relatively niche tool, there are plenty of options to choose from. All premium compost bins feature ventilation, durable materials and an easy-to-use drum mechanism. However, to narrow down the best choice for your home, consider the capacity and number of chambers.

The capacity is pretty simple: it’s the maximum amount of organic matter your mug can hold, and it’s usually measured in gallons. The larger the capacity, the more compost you can produce. Be aware, however, that larger capacity options take up more space and tend to be more expensive. For those with a small budget, small organic waste output, or small deck or yard, they may be more than you need. (Check the dimensions beforehand to make sure the composter of your choice will fit in your space!)

Next, decide whether you want one or two composting chambers. Since the production of compost can take a few weeks to a few months, you can keep two separate batches in operation at the same time with a two-chamber unit. This way you can add new waste to one side while the other side is in the composting process. Again, however, bicameral units are typically larger and more expensive.

These are four of the best-selling, highest-rated compost cups available on Amazon. They are available in different sizes, capacities and prices.

1. The best overall compost cup

The FCMP Outdoor Store’s 37-gallon composter has nearly 10,000 reviews and an overall rating of 4.5 stars. This makes it the most popular choice on Amazon. Critics love it because it’s well made with BPA-free, UV-inhibited materials, has good quality ventilation, and is capable of making compost in just two weeks if put in the right environment. After all, it’s easy to use and rotate, and has two chambers so you can run two batches at the same time – all for less than $ 100. (According to some reviewers, the only downside is assembly; it takes a while.)

  • Capacity: 37 gallons
  • Chambers: two
  • Dimensions: 36 x 30 x 28 inches

One reviewer wrote: “I can’t tell you how quickly this breaks down my kitchen and garden waste. [… and] I can’t believe how much I’ve put into this thing. After 90 days I stopped feeding one side so I can finish it and use it in my garden. ”

2. The runner-up: A single-chamber model for a little less

If you’re looking for something that is simple, affordable, and well-rated, the Miracle-Gro small composter is the place for you. The 27.7 gallon capacity is small enough to fit in tight spaces, but the durable construction is BPA-free, food-safe, and UV-protected. Although there is only one chamber, the internal mixing rods and ventilation holes allow you to make ready-to-use compost in just 4 weeks. Critics say it’s really easy to turn (even when it’s full) and it’s a “great composter for the price!” According to a customer: “The assembly took 20 minutes because only a Phillip screwdriver was needed.”

One reviewer wrote: “Perfect for the price. This small compost bin is just the right size for a small garden. It was easy to assemble and of a manageable size. And I don’t have to turn compost over manually. ”

3. The best compost cup for small spaces

For those who are short on space or just don’t compost a lot, this compact roll composter is small enough to fit on most balconies and the smallest of yards. It only holds 19 gallons of compost and has no metal space to save space. Thanks to the wide door and ergonomic handles, it is still easy to load and turn. Because it has reliable ventilation and internal ribs, the waste is broken up into compost in a matter of weeks. In terms of construction, the materials are recycled, BPA free and UV resistant. Get it in green or blue. It’s also the easiest to put together. “Let’s just say the setup took as long as opening the box it came in, less than 10 seconds. All you have to do for assembly is slide the door in and stand on the base, ”explained one reviewer.

  • Capacity: 19 gallons
  • Chambers: one
  • Dimensions: 24 x 24 x 12 in

One reviewer wrote: “We were looking for a small, slightly hidden composter and this little guy is perfect. […] The mug comes fully assembled so that it literally goes straight from the box to the garden. ”

4. The best large capacity compost cup

If you have a large garden or large organic waste, the lifetime rotating composter is well worth the effort. It has two bins that hold 50 gallons each, which means you can make up to 100 gallons of compost. This one also has some handy features that others don’t, including a spring-loaded pin that locks the kegs in place when they are loaded, and a processor gauge that lets you see how your compost is doing. In addition, the mug is designed to be turned easily, no matter how full it is.

  • Capacity: 100 gallons
  • Chambers: two
  • Dimensions: 65 x 31 x 43.3 in

One reviewer wrote: “We have a solid half acre of land for gardening, so I wanted something big. This stands above the ground and has a crank for regular rotation. I love that it’s closed – so you don’t have to deal with the clutter, smell, and fire hazard when composting in the heat of our desert sun. Excellent!”
