Below are four high-tech home composters that will easily allow you to turn food waste into flora feed.

Mill

If you’re a family that generates a lot of food waste, then the Mill might be for you. Looking like a kitchen trash can—though decidedly more stylish—the Mill is a 6.5-liter composter that only needs to be emptied once a month, not bi-weekly like most other home composters.And just because Mill’s compost is hanging around indoors longer doesn’t mean you’ll be forced to smell it. Activated charcoal filters, which only need to be replaced annually, eliminate 100% of odors contained by the Mill. It isn’t picky either. Meat, dairy, bones, pits—Mill takes them all and grinds and dehydrates them overnight, reducing them by 80% of their original mass.

The Mill is available for $999.
