Sun-Mar Tumble Style Garden Composters for compostable Kitchen and yard garbage do not produce finished compost any faster than a well-managed compost bin or open pile, but then most people don't manage their compost well or at all because it isn't easy or convenient to water and aerate compost in order to maintain a well aerated compost bin or pile.  Most of us leave our compost pile or bin to molder along at a its own sluggish pace.  This process is sometimes referred to as maintaining a cold pile and it takes substantially longer to digest your scraps and garden waste in this way.  

You are far more likely to turn the contents more often in a tumbler than digging compost out of the bottom of a bin or pile and spreading it over the top of the pile or pitch forking and watering your open pile regularly.  Turning the crank introduces air one of the vital ingredients necessary to turn vegetable matter into compost.  If you're interested the other ingredients for composting are nitrogen, carbon and water.

Tumble style composters also have the advantage of retaining moisture better, are odour free and pest resistant. Not only that but our composters are neat, clean and unobtrusive while  speeding the composting process!
