Frequently Asked Questions

How does Zera Food Recycler work?
The Zera device uses oxygen, moisture, heat, and agitation to speed decomposition of a week's worth of food scraps within 24 hours*. The additive provides the "brown" material necessary for the decomposition process.

How is the Zera food recycling process different from the traditional composting process?
The Zera food recycling process converts food waste into fertilizer through a fully automatic process, accepts a variety of food types including meat and dairy, and can be performed inside your home within 24 hours.* Unlike traditional composting, Zera Food Recycler automatically controls moisture, heat, air, and the process is not exposed to unwanted pests or wildlife. Traditional composting takes months to process, requires a large outdoor space, manual heap maintenance, and can attract pests and wildlife.

What types of food can the Zera device recycle?
The Zera device can recycle 95% of a typical family’s household food waste (including meat and dairy). It is not recommended to recycle large bones and pits.

How large is the unit?
Zera Food Recycler is designed to seamlessly fit in your kitchen. It is counter height so that food scraps can easily be deposited into the unit. The dimensions are 11"W x 22"D x 33.75"H.

How much does the unit weigh?
Zera Food Recycler weighs 118.6 pounds (53.8 kilograms).

How much energy does the device use per year?
The Zera Food Recycler energy consumption is approximately 300 kWh/year, assuming a cycle is run once a week.

How often do I need to run a cycle?
A cycle should be run once food waste is filled to the top of the mixing blades. It can be run more frequently if desired, even daily. The Zera Additive must be used each time you run a cycle.

How long does it take a cycle to run?
A cycle will complete within 24 hours.

Once a cycle is started, can it be paused to add additional food waste?
Yes, once the cycle is started, you can pause it during the first 30 minutes to add additional food. Once it is past 30 minutes, it cannot be paused, but the cycle can be cancelled. If cancelled, the cycle will restart when the Start button is pressed.

Why can't food scraps be added after the 30-minute window has passed?
The device needs enough time to fully process any food added to the cycle.

Is the device child-resistant?
Yes, the controls can be locked out (through the control panel or the mobile app). Additionally, the lid locks when the cycle is active, so children cannot access the mixing compartment. Finally, there is a retention tab on the output bin.

Is there anything special required for installation?
No, simply plug Zera Food Recycler into a standard power outlet. It has a 6-foot power cord to provide flexibility of placement.

What is the output of Zera Food Recycler?
The output of Zera Food Recycler is a ready-to-use, homemade fertilizer that can be used on lawns and gardens. It appears similar to coffee grounds, is dry, and spreads easily.

Is the homemade fertilizer the same as compost?
The homemade fertilizer is not standard compost because it is not created from a traditional outdoor composting process. Instead, it is a ready-to-use homemade fertilizer that, once spread on the lawn and garden, will release nutrients into the soil as it continues to mature.

How should the output be used?
The homemade fertilizer should only be used outdoors. It is recommended to apply the homemade fertilizer on the soil surface, not to exceed ¼-inch thick. Keep the product away from roots and plant stems.

The homemade fertilizer can also be broadcast on grass using a lawn spreader.

How should the homemade fertilizer be stored?
The homemade fertilizer should be stored in an air-tight container in a cool, dry area (i.e., garage, basement, closet) for up to six months.

Will the homemade fertilizer attract bugs during storage?
The homemade fertilizer should not attract insects, especially if stored in an air-tight container as recommended.

What is the Zera Additive made out of?
The Zera Additive is made from coir and baking soda. Coir is made from coconut husk, a rapidly renewable plant-based resource. The Zera Additive Pack is made from paper and designed so the entire additive (including bag packaging) can be placed in the Zera device.

How often do I need to use the Zera Additive?
One Zera Additive Pack is used every time a cycle is run. It is estimated that on average, a U.S. family will run a cycle once a week.

How does the Zera Air Filter work? What is it made of?
The Zera Air Filter is made of carbon and HEPA layers. It is designed to continually filter air.

Where can Zera Food Recycler be shipped?
We ship anywhere in the United States (including Alaska and Hawaii).
