best compost bins

Staff

With a decent patch of outdoor space, it’s fairly easy to start your own compost pile. And, if you’re itching for a DIY project, building a rotating compost bin isn’t terribly complicated. But if you don’t have time or the ability to make those options happen, buying a compost bin is relatively inexpensive and gets the job done. Food scraps and yard waste account for 30 percent of what we throw away, and composting keeps it out of landfills. Whether you have a compost bin on your countertop or a large one by the side of the house, every bit counts.

What to Consider

Of course, the first thing to nail down is where your compost will live. Outdoor bins are typically made from recycled BPA-free plastic and start at a 30-gallon capacity and go all the way up to 100 gallons or more. Indoor bins—usually set on the countertop or underneath the sink—have a 2- to 3-gallon capacity. Aesthetics, preventing fruit flies, and keeping odor under control are top considerations for something that’ll be in your kitchen. In terms of cost, most outdoor compost bins are usually about $100 or less, and countertop or under-sink versions typically run $40 or less.

How We Chose

Our selection includes top-rated compost bins for indoor and outdoor use. All of our picks have at least 4 stars, and the majority of what we feature below gets 4.5 stars or more. We chose kitchen bins in assorted styles and materials to suit individual tastes. Outdoor options include continuous compost bins — essentially large containers that let nature do the work and require very little maintenance — and batch bins, which include tumblers.

Best for Backyard Gardeners

Algreen Classic Compost Bin

$81.90

This durable and substantial bin is ideal for backyard gardeners who need more compost than an indoor model can produce. Fill it regularly and you can expect to get dark humus in roughly six to eight weeks. The bin’s thick walls retain heat, which traps moisture to speed up the breakdown process. It has a 94-gallon capacity, made from BPA-free recycled plastic with a lid that has holes for collecting water so the bin doesn’t need to be opened. The compost empties out of two sliding doors at the base.

Best Large-Capacity

D.F. Omer Composter Bin

$76.99

If you need a large amount of compost for a landscaping project or an expansive garden, this option is your best bet. It has a whopping 110-gallon capacity and it produces compost in roughly four to six weeks or less in summer. It’s made from black BPA-free recycled plastic that retains heat well, with two top doors for emptying waste inside and a large panel on the bottom for removing compost. Assembly is as easy as snapping the sides together.

8

Best Tumbler

FCMP Outdoor Tumbling Composter

A tumbling composter allows you to make compost in less time—with a little elbow grease. Using a hand crank to mix the compost introduces more air, and keeps things moving to speed up the process. There are two chambers so you can work on composting one batch while adding fresh waste to the other, and fins inside help break up any clumps. You’ll only need to turn it five or six times every two to three days, which isn’t that heavy a lift. The composter is made from post-consumer recycled polypropylene, which is BPA-free and blocks UV rays.
