About Compo Soil

Compo Soil is your new essential device for your kitchen to recycle the food waste. No more smelly, leaky garbage, or throwing food scraps away to rot in landfills. With Compo Soil, you’ll be able to turn your waste into nutrient-rich soil. Revolutionize the way you deal with waste, while giving nutrient-rich soil back to the earth.

Compo Soil accelerates the composting process, decomposing organic matter (like food & plant waste) into CO2, water, and nutrient-rich dirt. 

Compo Soil does this by harnessing both physical and bio-chemical means of breaking down food waste. Our modes (Grow, Eco-Express, and Compo Soil Approved) guide Compo Soil through the three main stages of composting while maintaining ideal conditions for microorganisms to thrive. 

The sensors in Compo Soil ensure proper moisture content, warm temperatures, and plenty of oxygen to create the optimum conditions to speed up the natural decomposition process. This also stimulates aerobic decomposition (decomposition by microbes that require oxygen) which is the most efficient and rapid way of composting with minimal odour production.

Compo Soil's processing time is between as little as 3-6 hours!

Compo Soil enhances the biodegradation rate of the kitchen waste using heat, moisture and smart sensors, resulting in organic matter which is a great source of nutrients for the top-soil. This soil amendment is rich in Nitrogen, Phosphorus and Sodium.

Yes! Using Compo Soil is as easy as the push of a button! Don’t worry, Compo Soil will come with a full manual as well!

Compo Soil contains a lot of fancy patent-pending sensors to create the MOST nutrient-rich dirt possible inside your home! Compo Soil begins by compacting the contents, while temperature and humidity sensors optimize the microbial environment to intelligently break down the food scraps without losing any vital microorganisms. This leads to mass and volume reduction, while providing continuous airflow as our heavy-duty grinder churns the waste.

Compo Soil uses a single button that’s very intuitive and user-friendly.

Compo Soil cosumes about 0.8-0.9 kWh/cycle, which means it costs just pennies for each cycle!

378 x 280 x 310mm

Compo Soil's max capacity is 3L or 1.5kg/cycle but we recommend filling Compo Soil ¾ full for best composting results!

Compo Soil weighs about 10kgs (19-20lbs).

Compo Soil in the USA and Canada will be 110V. The EU version will be 220-240V with a type C plug. The Australia Plug is 220-240V.

Compo Soil makes noise comparable to other small countertop appliances which is less than 40 db. (Don’t worry, that’s a lot less than a blender or food processor!) It’s around the same or less than a coffee maker, modern dishwasher, etc!

We’ve found on average, a family of two might use it about twice per week! A family of 4 may use it once per day - it really depends on your preferences and how much food waste you create!

Compo Soil does not have to run everyday but we don’t suggest letting food scraps sit in Compo Soil for extended periods of time, as it may lead to odors.

Compo Soil comes with pre-installed activated carbon filters which adsorb odours and purifies the air from any bad smells. 

There are a couple reasons for Compo Soil's’s price point! First, Compo Soil is the first home composter with a full program of compatible bioplastics that will change home composting forever. Comparable home food composters cost $800+ and offer less convenience and functionality than Compo Soil. Second, we manufacture in a Carbon Neutral facility with exceptional standards for workers. Lastly, the heating and abrasion mechanisms are top-of-the-line and are expensive to produce.

No, Compo Soil is completely new technology and Patented!

Compo Soil does 3 things (not just 1!) it breaks down waste, creates compost and decomposes bioplastics; whereas, others only dehydrate your food and don’t create a nutrient rich compost. Remember: Compo Soil is completely new technology and Patented!

Compo Soil is so much more than a dehydrator, it uses completely new, patented technology which uses smart sensors to preserve microorganisms to create the start of richer, more nutrient dense compost once mixed with soil. It is also the only in-home machine on the market that can break down bioplastics!

Compo Soil is produced in our manufacturing plant in China which is ALWAYS carbon neutral! We pride ourselves on being a B-Corp, carbon neutral and waste-free! Compo Soil also lessens GHG emissions through emissions avoidance (i.e. avoiding the GHG emissions caused by sending food waste to landfill), and carbon storage (i.e. healthy dirt captures carbon and improves soil health).

Compo Soil Pre-Installed Filters

Compo Soil's filters are Pre-installed meaning you do not have to change them. Our Engineering team has conducted tons of tests to ensure the quality of the air coming through our filters is well within the permissible limits for clean breathable air.

Activated carbon is a carbon-rich solid that is derived from biomass. Compo Soil's activated carbon has millions of tiny pores in the activated carbon that increase the total surface area, therefore allowing more gases to be captured. The greater the surface area the greater the adsorption capability of the activated carbon. Essentially, it works like a sponge that can absorb and trap gaseous molecules.

In comparison to the other filter options available in the market (eg. HEPA or UV), activated carbon filters may not be as efficient because they don’t have a glass fibre filter. But Compo Soil's filters have been designed to ensure it is one of the most environmentally sustainable options and accounts for the least amount of waste.

Compo Soil filters use activated carbon to trap moist air, remove gases from circulation and reduce unpleasant smells. They are designed to filter out odours, pollutants, and hydrocarbons such as volatile organic compounds (VOCs) from the air via adsorption (ad-sorption not ab-sorption). Adsorption is a distinct process whereby compounds in the air react chemically with the activated carbon and adhere to this solid material’s surface. This causes the compounds to be trapped in the filters (stuck to the carbon) instead of released into the surrounding air. Compo Soil filters also absorb moisture and therefore decrease the amount of condensation that would otherwise occur on surfaces behind/beside Compo Soil's exit airflow. All in all, the Compo Soil filters ensure that the air coming out of your Compo Soil is less smelly, purified, and safe.

Compo Soil filters are a proprietary dual activated-carbon filtration system. Compo Soil has 2 filters, designed and placed in series to maximize the efficiency of filtration.

The carbon filters are refillable (YAY!) and last between 3-6 months with regular use! You will know when to change your filter when the handy “Change Filter” light comes on! Better yet, the carbon you are discarding can be used as a fertilizer for your garden as well - no waste here! If for any reason you need to dispose of the outer plastic filter, we will take those back in our Compo Soil 360 program to recycle the cartridge properly!

Compo Soil Compost

The Compost Compo Soil produces is neutralized. It's actually safer than most home compost because the high temperature in Compo Soil eliminates any pathogens that could be present.

Compo Soil uses smart sensors to manage heat, continuous grinding and moisture in the organic matter to break down the bioplastic and biodegrade the polymers chains on a molecular level. This causes an accelerated disintegration and biodegradation of biodegradable materials than when placed in a typical compost environment.

Compo Soil compost will differ depending on variables like humidity and the assortment of food scraps and/or Compo Soil Approved bioplastics you add.

Max volume reduction in mass is around 80%.

Of course, we recommend 1:10 (Compo Soil Compost:Soil)!

The answer is yes, you can get dirt from just only composting egg shells. The end product however won't have the optimum Carbon:Nitrogen ratio to serve as a natural fertilizer. And for such cases, additives can be added to balance that ratio - so no matter if you put just the egg shells or just lettuce in your Compo Soil, you will end up with compost at the end.

Yes! The end product from Compo Soil is true compost. The compost produced in our Eco mode is the most mature out of all three settings - it’s rich in microbial cultures and organic matter that can provide nutrients to the soil.

Compo Soil Approved bioplastics will require certification to ensure the material undergoes degradation by biological processes to yield CO2, water, inorganic compounds, and biomass at a rate consistent with other known compostable materials and leave no microplastics.

Compo Soil enhances the biodegradation rate of kitchen waste using heat, moisture and smart sensors. In Grow mode, this results in organic matter which is a great source of nutrients for top-soil. This soil amendment is rich in nitrogen, phosphorus and sodium.

Yes in small amounts, but we don’t recommend them as they’re highly recyclable items, so save your Compo Soil for non-recyclable things!

Yes, in very small amounts and only small bones such as chicken or fish. For bigger bones, we suggest making broth with your beef bones then give them to your dog.

Yes, in small quantities! We recommend mixing them with low sugar items like veggie scraps, plant debris or grains.

It can, but that doesn’t mean you should! We don’t recommend wood shavings to go in Compo Soil.

Yes in small chunks, better to break them up into pieces roughly 5x5 cm so they can break down quicker!

No, avocado pits are too hard unfortunately!

Compo Soil can handle cotton but we suggest it's best to recycle and reuse those fabric scraps.

Unfortunately, no you cannot use Compo Soil for pet waste.

No, any oils, liquids or grease must be drained out. If you’ve stored waste in the freezer, thaw and drain before adding it to the appliance.

Always add food waste along with bioplastics when you run a Cmpo Soil Approved cycle. A ratio of 10% bioplastics to organic waste is optimal and should not be exceeded.

You can run a load as small as you want however, there is a line on the bucket indicating the maximum capacity. A smaller amount of waste on a cycle will likely finish earlier. DO NOT OVERFILL OR RUN EMPTY!

We don't recommend you add to Compo Soil once it's running because during a cycle and just after the bucket and contents of Compo Soil will be hot. If you've forgotten something, just put it aside for the next Compo Soil cycle. If you do pause Compo Soil to add more waste, the cycle will start again.

Cleaning Compo Soil

Knowing how to keep Compo Soil clean is important so that it stays looking great and also continues to function at its best. We recommend cleaning the Compo Soil exterior once a month or as frequently as you would clean any other kitchen appliance. To keep your Compo Soil at optimal performance, clean the interior of the bucket routinely.


- Ensure your Compo Soil is unplugged before cleaning. To wash the exterior of Compo Soil, simply wipe with a damp dish cloth. If your Compo Soil is particularly dirty, add a small amount of dish soap to your cleaning process.

Note: Compo Soil’s lid should NOT go in the dishwasher.

- Finally use a dry cloth to remove excess moisture.  

- Never submerge Compo Soil under water. There are electrical components and any excess water would cause significant damage and could cause electric shock.


- The bucket can be easily removed and washed by hand or placed in the dishwasher, for a more thorough cleaning. 

- Ensure the bucket is free from any excess dirt/particles before placing it in the dishwasher. This should be run on a hot cycle.

- As the bucket is made from metal be sure to let it cool down before handling and placing it back inside the Compo Soil unit.

Operating Compo Soil

Depends on which cycle you run! 

Grow: Compost from grow mode has the most nutrient and microbial density. It can be mixed into the soil of your garden or house plants! (Or thrown into your compost, green bin or waste bin.)

Eco-Express: Toss the Compost from this quick mode into your home compost, green bin or waste bin. 

Compo Soil Approved: When you use Compo Soil to break down Compo Soil Approved products or packaging, throw that dirt into your green bin or waste bin.

To reset the appliance, press the main button for 10 seconds or more.

If a cycle is running longer than you'd expect, there's a chance your Compo Soil is actually on the Grow or Compo Soil Approved mode. The light indicating which mode you're on will shine brightest underneath the mode it's running.

It is normal for Cmpo Soil to beep when loading the bucket, securing the lid and when changing settings or turning the appliance on or off.

The lid will lock in place when you align the unlock arrow on the side of the lid to the arrow below and then turn the lid to align the lock icon over it.

We do not recommend letting food sit in Compo Soil for more than 2-3 days. The filter odour control is not active while Compo Soil is not running a cycle, so you might smell it. We recommend running a smaller cycle if need be so that you are not leaving waste in there for too long.

Yes you can. Compo Soil will remain in standby mode with negligible electricity use. Electricity usage when plugged in but not running is 0.0011-0.0013 kW.

You can put Compo Soil in any corner of your kitchen when not in use, but when you run a cycle make sure to place it 6-12 inches away from the wall. Also, avoid placing it under overhead cabinets due to the steam that can be produced as Compo Soil breaks down your food waste.

Compo Soil CANNOT be stored in a garage or outside! It should be kept inside due to the risk of temperature changes and humidity.

Compo Soil will automatically go to standby/power off 30 minutes after a cycle. There’s no need to turn it off, you may choose to unplug Compo Soil once it’s finished a cycle.

Compo Soil can be controlled from a single button. 

Hold the main button down for 3 seconds to select the modes: Grow, Eco-Express and Compo Soil Approved.

You will know you have switched to a different mode when the green light moves over to the next icon and Compo Soil beeps once.

- Once your desired mode is selected, press the main button for 1 second to start the cycle, the button will light blue. 

- As the mode goes through its various cycles (drying, mixing, cooling), these lights will illuminate green. 

- When the cycle is complete, the main button light will turn green and all the cycle lights will also be green.

Cycle Issue

Make sure the plug is secure in both the wall outlet and the unit. If problem persists please contact us!

It could be that the notches on the metal gear inside Compo Soil and on the bottom of the bucket are not aligning properly.

To fix this, pull the bucket out and turn the grinder or turn the small metal gear on the bottom of the bucket (this will also move the grinder) to change the position of the gear on the bucket so that it lines up with the one inside Compo Soil. Place the bucket in again and you should hear the click once the gears are lined up!

While it’s normal to have a slight smell when working with food waste, it is best to run a cycle when you can and not leave unprocessed waste in Compo Soil for more than a couple days. If you notice your Compo Soil is a bit too ripe, it may also be time to change the activated carbon in your filters. Remember to change the filter while the machine is off.

During a cycle and just after the bucket and contents on Compo Soil will be hot. There may be some steam emitted.


To restart, close the lid and press start. This will restart the cycle. Please avoid opening the lid halfway. The full cycle might take a shorter time with half processed waste.

While running, Compo Soil will make some minimal noise. When it has bigger chunks or harder bioplastic there may be an occasional grinding noise. If there is a loud constant grinding noise something is likely stuck.

- Turn Compo Soil off.

- Allow it to cool for 30 minutes.

- Remove the obstruction.

- If possible add more organic waste when you restart it to ensure a smoother cycle.

As Compo Soil uses heat to break down waste you will notice some steam come out of the back of the machine where the filter is. This is all part of the process and is totally normal! The amount of steam you see also depends on the moisture content of the waste you put in.

Make sure to put your Compo Soil 6-12 inches away from the wall and avoid placing it under overhead cabinets.

This may happen, do not be alarmed! Your Compost will look different depending on what waste goes in! You can always run another cycle with additional food waste to further break down remaining waste.

Compo Soil is not waterproof and is an electric appliance that should not come into contact or be submerged in water. Use high caution if water has been spilt near the unit or cord.
