1. The CompoKeeper

a. Where can I buy the CompoKeeper?

You can buy the CompoKeeper right here or explore our store locator to a find our favorite outlets near you.

b. What are the dimensions of the CompoKeeper?

The dimensions are 17” tall x 11” wide x 15” deep. 

c. How is the CompoKeeper different from a regular trash can?

The CompoKeeper has a unique design with two interlocking clamps that work together with our compostable bags to keep odor under wraps. The sealed bag traps smelly gases while the breathable bags and ventilated keeper allow air to circulate, preventing the contents from becoming anaerobic (aka: super stinky). Plus, the odor absorbing carbon filter provides extra piece of mind.

d. No fruit flies? Really?

Fruit flies hunt for ripened or fermenting fruits and vegetables making your compost bin the perfect destination. But when sealed, the CompoKeeper disguises its contents and fruit flies buzz off. If fruit flies make it through the near-impermeable wall, well…they wouldn’t dream of escaping. Keep in mind that fruit flies lay their eggs on the surface of fermenting foods, in garbage disposals and sometimes mops and cleaning rags. If fruit flies are driving you up the wall, you may want to rethink your fruit bowl or try a natural fruit fly trap.

e. Why are there two foot pedals?

We wanted to make the CompoKeeper as easy and hands-free as possible, so by adding another pedal we put the power in your…feet! The right pedal opens the lid and clamps. The left pedal seals the bag and closes the lid.

f. What happens when the CompoKeeper is full?

When your CompoKeeper is full, tie up the top of the bag, grab both sides of the bag tote and lift the bag out through the open clamps. The tote will protect your floors from a leaky bag while you accompany your compost to the outdoor bin. Watch this video to see how to empty the CompoKeeper. Then, you can process the food waste into compost with one of these tried-and-true methods: a curbside composting service, drop-off/community garden composting, backyard composting, worm bin composting, or Bokashi composting.

g. Where did the idea of CompoKeeper come from?

CompoKeeper is the brainchild of a dad-daughter duo. When their hometown, Boulder, Colo., initiated a curbside composting program they jumped at the opportunity to make this eco-friendly behavior easy, clean and practical for all homes, big or small. CompoKeeper technology was created to help keep kitchens –the heart of the home – clean and comfortable, just like they should be. Read more about the CompoKeeper team here.

e. Will the bags breakdown in my backyard compost pile?

Our bags are 100% compostable, intended to be composted in a commercial facility. The US does not have any certifications for backyard systems because, with differences in climate, material and maintenance methods, it’s difficult to create a standard. However, Many backyard composters have found that, in the right conditions, compostable products do decompose successfully. Municipal facilities define the right conditions as a consistent temperature of 165 degrees Fahrenheit for 30 days. Check out our blog on backyard composting for tips on how to heat up your compost pile.

CompoKeeper’s Recommendation (refer to our lifestyle quiz to determine your composting style) 

Compost Connoisseurs – leave the bags out of your gourmet blend and bury them in the ground instead.

Curious and Effortless Composters – add the bag in with the rest of your compostables.

On average, compostable bags can breakdown in 3-6 months.


f. Are the bags GMO free?

Yes! The resin we use to make CompoKeeper compostable bags has been tested by Eurofins Gene Scan, the Global leader in GMO detection, and is certified GMO-free.

h. Do I have to use CompoKeeper bags?

The CompoKeeper works with any bag, however, CompoKeeper’s compostable bags are the perfect companion to the CompoKeeper compost bin. Our bags are breathable which helps with odor control, more durable for extended storage and the perfect fit to minimizes wastefulness. We recommend using CompoKeeper’s compostable bags for your best experience.

4. Activated Carbon Filters

b. How often do I need to change the filter?

Your Activated Carbon Filters should be replaced every six months.

c. How can I use the filters without the lid?

The filter was designed to live in the lid of the CompoKeeper, however, you can still use the filter when assembled for under-counter storage by laying it flat on the bottom of the bin, underneath the bag tray. In this location the filter will not get in the way of the mechanics.  

d. What can I do if my filter holder opens when I’m use the CompoKeeper?

We have to suggestions to help keep this from happening. 

  1. First check the hinge connection (the end closer to the back of the lid) to make sure the cross bars are fully snapped in.
  2. There is a small hole in the opening end of the filter holder where you can insert a small (#6 plastic) screw.
