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.
