The Bio-Orb Composter is 36" in diameter and holds 97 gallons. It's easy to assemble and start composting!

The Bio-Orb Composter is an environmentally friendly way to turn yard clippings and organic scrap into rich, humus, used to enrich the soil in your garden or yard. The Bio-Orb is designed to make composting fast, easier and neater. The spherical shape maximizes heat retention for faster composting and allows for easy mixing and mobility. The rolling of this tumbler provides oxygen, mixes the material and speeds up the composting process. Roll the Orb every 2 to 10 days. Rolling more often than every two days will not allow proper heat build-up while rolling less often than every 10 days will not provide enough oxygen to the contents to ensure the fast Bio-Orb composting times.
