Composting is natural recycling at its best. Organic waste, like mowed grass or your leftovers from dinner, make up 30% to 50% of the amount of garbage people throw away each year. While you won’t be able to compost all of your household’s organic waste, composting significantly reduces the overall amount of trash you’ll throw out each year.
Quick look: The best composters to buy in 2019:

When you throw out organic waste, it sits in the landfill and decomposes. During decomposition, organic waste releases a potent greenhouse gas called methane. Methane has many harmful side effects. While the technology landfills require to capture methane has significantly improved in recent years, the best method of capturing methane is to eliminate it at its source. This is one of many reasons why composting is so important. As an added bonus, composting also creates excellent food for your plants.
While many people like the idea of composting, few of us have the time required to maintain and tend a traditional compost pile. This is where investing in a home composter can be beneficial. These machines hasten the composting process and eliminate the need to maintain an unsightly compost pile.
As composting has become more popular among gardeners and homeowners, an increasing number of composter bins and tumblers have hit the market. These models vary widely in design and price, and with so many options to choose from, it can be difficult to know which one will best fit your needs. Composting is a simple process, and a superior composter should be simple to use.
Compost Bins vs. Compost Tumblers: Which One Is Right For You?
If you are searching for a new composter for your garden, it is helpful to divide composters into two primary categories: compost tumblers and compost bins. Although both options are effective at composting, each type has its own set of advantages and disadvantages. Understanding the benefits and features that each one has to offer will make it much easier to choose the one that best suits your needs!
Here is a quick look at how the two compare to one another:
- Top loading
- Made from heavy duty construction grade materials
- Mixes and aerates while spinning
- Lower storage capacity
- Empties from the top
- Has a completely sealed design
- Top loading
- Made (usually) from plastic resin
- Has minimal aeration
- Higher storage capacity
- Empties from lower doors or ports
- Has no “true” bottom
Size and Portability
In terms of dimension, composter tumblers and bins are usually roughly the same size – occupying between 6—8 square feet of space. Because most compost bins feature an open bottom, they are not designed to be moved after being filled. The majority of compost tumblers are also designed to be stationary, but an increasing number of models now feature wheels that allow the tumbler to be wheeled to the location where the compost will be emptied.
When it comes to capacity, compost bins tend to hold 2 to 3 times more organic waste than tumblers. On average, a bin can accommodate 45 to 150 gallons of waste (depending on its size), while tumblers hold between 25 and 115 gallons of composting materials. The disparity is due to the design of compost tumblers. Under large loads, a compost tumbler’s drum becomes difficult to properly spin.
Because compost tumblers are usually made from construction grade materials, they are more durable than compost bins. Heavier materials are used in their construction because the tumbler must be able to support the whole weight of the materials being composted. When you are looking for a new composter, be sure to examine the central axis connection and the supporting legs for sturdiness. If the drum offers handles to assist with spinning, these should be strong as well.
Composting bins are crafted from lightweight plastic, usually a plastic resin, since they do not need to be moved. The downside to using these materials is that, over time, they will become brittle when exposed to the elements. It is not uncommon for the plastic to chip or crack with age.
A compost tumbler is designed to “turn” the compost. In general, the drum will need to be turned several times once or twice a week. Because a tumbler essentially “mixes” the composting ingredients, it makes the composting process quicker and easier. The sealed tumbler generates more heat, which hastens the decomposition of the organic waste it holds. On average, a batch of compost will mature in 6 to 8 weeks.
Using a compost tumbler is not always simple. The drum can become quite heavy as more and more materials are added to it, and larger units can require two sets of hands to turn. However, after the compost has matured, it is easier to empty a tumbler than it is a bin. If the whole batch is finished maturing, then a wheelbarrow can be wheeled directly underneath the tumbler, and the compost can be emptied into it.
By comparison, the design of compost bins makes it difficult for gardeners to turn the compost. For this reason, most gardeners simply do not even try. The lack of turning produce less aeration, and as a result, it takes longer for compost placed in a bin to mature. Although it depends on the time of year, it will, on average, take compost 8 to 12 weeks to mature in a bin.
Once the compost is mature, it is often difficult to extract from a compost bin. The mature compost is located at the very bottom of the bin and is compressed by the weight of the organic waste on top of it. Because using a shovel could potentially damage the bin, most manufacturers recommend using a hand trowel or hand spade to remove mature compost from a bin. This process can be tedious and time consuming.
Because of the additional features they offer, compost tumblers are significantly more expensive than compost bins. Generally, tumblers cost approximately 30% more than bins. The tradeoff is that tumblers are more durable and longer lasting than bins.
