Cooking is an adventure. Cooking is fun. But cooking at home also produces a lot of waste. Even if you're making carrot top pesto and turning your Sunday roasted chicken into cubes of broth in the freezer, there's still a lot of food scraps stinking up your garbage. What's worse is that all of those scraps produce methane gas as they rot making it a major contributor to climate change, according to scientists at the United Nations.

If you’re ready to embrace a more eco-friendly set of lifestyle habits, then it’s time to think about the ancient art of composting. This allows you to process plant and food waste and convert it into an organic material that can be used as plant fertilizer. It helps reduce your carbon footprint and sanitation bill while transforming kitchen trash into a real treasure for gardeners. 

Effective at-home composting relies on a quality bin to store your waste and facilitate the composting process. Whether you’re seeking a compact freezer model, a larger bin for worm composting, or something in-between, here are the best kitchen compost bins.

Best For Worm Composting: Urban Worm Bag Worm Composting Bin

Urban-Worm-Bag-Worm-Composting-Bin

What We Love: All-natural, faster than aerobic composting, minimal odor

What We Don't Love: Worms must be purchased separately, must be temperature-controlled

Worm composting, also known as vermicomposting, happens when red worms are placed in a bin with moistened bedding (usually shredded newspaper or cardboard and soil) and fed a diet of fruit and vegetable scraps. The worms then digest the scraps, and their “castings” become odor-free and mineral-rich fertilizer. This process may make some composting hopefuls squeamish, but experienced compost makers know that worm composting is both natural and very easy. 

The Urban Worm Composting Bin boasts a simple and direct design; the worms live on their bedding inside the bag, the food is fed through the top, and the castings can be easily harvested from the bottom. The bag sits in an iron stand to keep it aerated, and this composting system can be stored either indoors or outdoors (at a temperature range of 55-95 degrees). Of course, something this big needs dedicated space and it takes at least 4 months before you have usable compost.

Material: Oxford fabric, iron | Dimensions (LxWxH): 27 x 27 x 31 inches | Capacity: 29 gallons

What to Look for When Buying a Kitchen Compost Bin

Size

Composting bins come in a wide range of shapes, sizes, and materials. Most countertop models can hold anywhere from 0.5 gallons to 2 gallons of food scraps. If your compost pile is close by, you might be able to get away with only needing to hold a few days of scraps at a time, no matter what your family size is. If you instead have to drop off your scraps weekly, you'll need a larger bin (and probably one that's freezer-safe). Backyard worm composters can hold more, but the exact quantity depends on the number of worms.

Maintenance

Fortunately, most compost bins require very little in the way of maintenance. Just put the food scraps in, wait until the compost bin is filled, and then add the waste to an outdoor pile or bin to convert it into fertilizer (or take the waste to a compost drop-off in your community). 

In terms of cleaning, most compost bins can be washed either by hand with soap and water or through a dishwasher cycle. You should do this every time your empty the bin to avoid pests.

Odor Control

Nowadays, many compost bins come with odor-preventing features like charcoal filters, and you definitely want to prevent them. Flies are attracted to the gases given off by rotting food. Ultimately, a secure lid will do more than anything else to keep odors and gases at bay. If you’d really like to eliminate any chance of food waste stink, then a freezer-safe compost bin might be your best option.

FAQs

What kind of food can be made into compost?

When composting food items, you’re always safe with fruits and vegetables. In addition, eggshells, coffee grounds, and tea bags can go into your compost bin without hesitation. Meat, dairy, and animal bones require higher temperatures when composting and secure areas away from pests. Whether to include those is either you if it's your own backyard pile, or the organization running the compost.

What should never be composted?

Fats, grease, and oils are rarely welcome in composting since they don't break down and attract pests. Human and animal wastes, as well as human proteins like hair, coated paper, and diseased plants should also never be in a composting pile.
