These Worm Composters Will Turn Those Food Scraps Into Nutrient-Rich Compost in No Time

If you’ve already made the switch to a more eco-conscious lifestyle and finally decided to ditch your plastic straws and plastic bags for reusable ones, you might be on the hunt for other things to do to further improve the environment. While you may be familiar with traditional composting—the process of breaking down food scraps and other organic materials to create a nutrient-dense soil additive—adding worms to the mix can make the process even easier (and more interesting).

Worm composting—also known as vermicomposting—uses the power of worms to break down natural materials in highly-ventilated, waterproof bins. The worms in the bins eat the food scraps you load in there, turning them into compost as they pass through their bodies. To start you off on the right foot, we've rounded up the best worm composters on the market.

What to Consider

Before investing in a worm composter, there are a couple things to consider, including the size of the bin, as well as the material it’s made of. If you’re familiar with traditional composters, they’re typically cylindrical or cuboid in shape and can hold between 20 to 100 gallons of compost. Worm composters tend to be significantly smaller than traditional composters, but they can still hold enough food scraps and other organic materials to create the right amount of compost for your lawn or garden. The worm composters on our list have capacities ranging from four gallons to 29 gallons.

Aside from how large the worm composter is, you should consider the material or materials that it’s made from. Nearly every option on our list is made of durable, high-quality plastic. Worm composters also frequently have a variety of internal trays to house the worms and compost, so if having delineated layers or trays is important to you, it’s worth noting whether or not the model you’re eyeing features those.
