What does the MB4 produce?

The MB4 produces dry food grounds from kitchen scraps. These dry grounds are significantly reduced in volume — by up to 93% — and can be added to potted plants, handed to a community garden, or disposed of with minimal environmental impact.

How fast does the MB4 work?

The MB4 processes kitchen scraps into dry food grounds in as little as 4 hours in Disposing mode (short cycle). For a full composting cycle, it runs for up to 24 hours. Add scraps before bed and wake up to dry, odor-free grounds in the morning.

Is the MB4 suitable for apartments with no outdoor space?

Yes. The MB4 is specifically designed for apartments and small kitchens. Its compact 4L design fits on any countertop, it operates at just 38dB, and its carbon filter system prevents odors — no outdoor space or garden required.

No. The MB4 uses a carbon filter system that neutralizes odors during processing. Your kitchen will not smell during or after a cycle. The carbon filter should be replaced every 3 months to maintain full odor control.

The MB4 operates at just 38dB — whisper-quiet. It can run overnight without disturbing sleep or household activities.

What is the difference between the MB4 and MB12?

The MB4 is a compact 4L food recycler for apartments and small kitchens — it produces dry food grounds ideal for disposal or potted plants. The MB12 is a larger 12L electric composter for families and gardeners — it produces a nutrient-rich soil amendment. If you have a garden, choose the MB12. If you live in an apartment, the MB4 is the right fit.

Does the MB4 have an auto-clean function?

Yes. The MB4 includes a 30-minute automatic self-cleaning cycle that keeps the inner bucket fresh. Simply run the auto-clean cycle after emptying the processed grounds to maintain hygiene with minimal effort.

How many people is the MB4 designed for?

The MB4 is ideal for 2–4 person households. Its 4L capacity handles daily food scraps from a small family, and its countertop footprint fits comfortably in any kitchen without taking up much space.
