A Better Way

Built for larger food waste routines

Some homes need more than odor control. If your household cooks often, prepares fresh produce, or wants to connect kitchen scraps with garden reuse, MB12 gives you a larger-capacity way to process food waste at home.

Traditional composting
The old way

Traditional composting

It can absolutely work, but it often needs outdoor space, regular turning, moisture control, and weeks or months of patience.

Space Usually needs outdoor space or a dedicated bin setup
Control Depends on weather, moisture, airflow, and regular turning
Upkeep More turning, checking, and trial-and-error
Daily Fit Easy to start, but harder to keep up with in daily home life
MB12 microbial composting path
The home version

MB12 microbial composting path

MB12 uses microbial fermentation and grinding to create a more managed pre-composting path for daily kitchen scraps.

Space Designed for kitchens, utility areas, or covered patios
Control Manages heat, airflow, humidity, and microbial conditions
Upkeep Less turning, checking, and outdoor pile management
Daily Fit Built for family-size food scraps and repeatable home routines

MB12 does not replace composting principles. It turns them into a format that fits modern home life more easily.

How it works

Food scraps go in. MB12 keeps the composting process moving.

MB12 uses microbes, heat, airflow, humidity, grinding, and mixing to help daily food scraps move into a cleaner home composting path.

Frequently asked questions

What kind of electric composter is MB12?

Yes. MB12 uses microbial fermentation, grinding, heat, airflow, humidity control, and mixing to help daily food scraps move into a managed home composting path.

Does MB12 make finished compost?

No responsible electric composter should promise fully finished garden compost in 48 hours. MB12 creates dry, reduced pre-compost that can continue breaking down in soil, an active compost pile, or a garden composting routine.

Who is MB12 best for?

MB12 is best for families, frequent cooks, and garden-minded households that want more capacity and a more managed home composting routine.

How is MB12 different from MB4?

MB4 is a countertop food recycler focused on odor control, wet-trash reduction, and daily kitchen relief. MB12 is a larger electric composter designed for households that want microbial fermentation, grinding support, and a home composting path.

Can I use the MB12 output in my garden?

Yes, but treat it as pre-compost for the next step. Cure, mix, or mature it further before using it in garden soil. It is not instant finished compost or direct plant food.
