OUR LEADING DESIGN: THE DRUM

THE COMPOSTING CHAMBER

Sun-Mar's Unique Bio-Drum

The ideal way to compost waste would offer operational simplicity, and an environment where there is warmth, moisture, organic material, and oxygen. Sun-Mar creates this ideal environment in the patented Bio-drum.

The unique Sun-Mar Bio-drum ensures aerobic microbes flourish and work much more quickly to break down waste and convert it back to earth.

 

Operational Simplicity

Waste and peat mix bulking material enter through the waste inlet port at the top of the drum. To mix and aerate, rotate the drum periodically, simply by turning the handle on the front of self-contained units or on the side of central units. During rotation the inlet door closes automatically keeping the compost in the drum.

To empty compost from the Bio-drum simply release the drum locker and rotate the drum backwards. Now, the inlet port in the Bio-Drum opens automatically and compost drops directly into the compost finishing drawer.

After rotating, the Bio-drum locks itself in a top dead center position ready to receive new material.

 

ADVANTAGES OF THE SUN-MAR BIO-DRUM

Supplying Oxygen

Sun-Mar's unique Bio-Drum design is the easiest and best possible way to thoroughly and completely mix and oxygenate the whole compost.

Rotate the drum, and the entire compost pile is tumbled and infused with oxygen. Oxygen is one key ingredient which allows aerobic bacteria to break down waste quickly and without odor.

 

Controlling Moisture

Moisture control, the other basic requirement for good composting, is one of the outstanding benefits offered only by Sun-Mar's Bio-drum.

Below 40% moisture content, composting slows and eventually stops completely. By not applying direct heat to the compost, Sun-Mar ensures that it does not dry out. In addition, the tumbling action during periodic mixing distributes moisture evenly throughout the compost.

At above 60% moisture content, liquid starts to drive out the oxygen in the compost, and the compost becomes increasingly anaerobic,- like a septic system. Sun-Mar's unique Bio-drum optimizes composting speeds by automatically draining any excess liquid through a screen at the bottom of the drum directly into the evaporation chamber.

 

Maintaining Warmth

The microbes generate their own heat as they work. This warmth is held in the compost by the mass of material inside the drum, supported by indirect heat from the base heater (in electric units). By avoiding direct heat, Sun-Mar ensures that composting will not slow down as the material gets dried out.

 

The Ideal Environment For Aerobic Bacteria

Uneven distribution of oxygen and moisture allows anaerobic bacteria to take over. These microbes produce bad odors and do not allow the waste to break down quickly.

The superior oxygenation and moisture control provided by the Bio-drum provides the ideal environment for aerobic bacteria to odorlessly break down organic material. They quickly convert organic material into water and carbon dioxide, and leave behind simple salts which are ideal for uptake by plants.
