Mantis composter for a constant supply of compost

The Best Composter Available... Here's Why!

Dual Chamber Design...

The original composter with two rotating 10-bushel capacity composting bins in one machine – allowing your compost to "cook" in one side of the composter while leaving room to fill the second side of the composter with plenty of organic scraps. Just add your compostable materials, turn the handle to spin the compost bins each day, and in just a few weeks you’ll have nutrient-rich fertilizer.

Largest Capacity...

The Mantis ComposT-Twin holds almost 25 cubic feet of raw material - that's 10 bushels in each chamber!

User Friendly...

The ComposT-Twin frame is a convenient 32” high for easy loading and unloading. The easy-crank handle and gear mechanisms make the composting bins easy to turn – even when fully loaded!

State of the Art Design...

Aerator vents on each door allow oxygen into the chamber while vented end caps assure even air flow and proper drainage. Two latches on each door means bin contents are more secure, and less stress on individual latches.

Clean and Neat...

Composting bin contents are fully enclosed to keep out rodents, pets, and other wildlife. No more messy, unsightly piles, no odors wafting over to your neighbor's porch.

Quality and Durability...

The ComposT-Twin is constructed of the finest quality materials and built for years of use. Our sturdy tubular steel frame and the galvanized composting bins are designed to last and last, year after year.

One-Year Money-Back Guarantee

We’ll give you one full year to try our composter. If you don’t like it, send it back for a complete, no-hassle refund.

ComposT-Twin is the Best.
