Sun-Mar Continuous-Use Auto Flow Composters

Item# 44-0108_set

A patented system for continuous composting


Using a patented, rotating bio-drum, the Continuous-Use Composter moves compost material along an outer drum and then back toward a collection chamber as it's turned. By the time it reaches the output port, it's a light, fluffy end product. You can load this composter with kitchen scraps continuously, making it unlike typical drum composters, which require you to stop adding material at some point. Made from green polyethylene. Minimal assembly. Canada.

Auto Flow Composter Features:
  • Environmentally friendly - Great fertilizer through recycling
  • Easy to use - dump kitchen scraps and yard waste in and turn the drum
  • Unique "Autoflow" double drum design prepares compost and delivers finished compost out the side
  • Quality compost fertilizes plants and improves soil structure
  • Combines the best features and advantages of both pile-type and drum-type composters
  • Approximately 50-gallon drum
  • Easy-to-use, snap-together design can be set up and ready to go in as little as five minutes
  • Pest resistant
  • Continuous compost production

Add raw composting material to the Sun-Mar Continuous-Use Auto Flow 200 & 400 Composters through the sliding input door. Mix and aerate compost material by rotating the crank. Rotating the drum allows compost to fall from the central output port, into your container below.

Composting is essential to an organic garden. Everything from coffee grounds, to fruit and vegetable scraps, tea leaves and more can be broken down to supply your garden with much of the nutrients that plants crave. In addition to the vast benefits to your back yard garden, composters reduce the amount of waste in our landfills. The Sun-Mar Continuous-Use Auto Flow 200 & 400 Composters are practical and easy to use. The AutoFlow design keeps compost material tidy and odor-free until it is ready for your garden.

The composter will not work well if at all during cold winter months ( temperatures under 40 F/ 50F). The enzymes needed to promote the compositing process slow down and almost become inert when exposed to cold weather.
