Removing compost is equally easy. Release the drum lock to rotate the drum backwards. The drum door remains open, and compost drops into the finishing drawer.

Excess moisture is removed automatically from the drum into the evaporating chamber through a screen in the rear of the drum.

The superb aeration in the Bio-drum^TM ensures an aerobic and therefore odorless breakdown of the compost.

Odor Free

As well as ensuring an aerobic breakdown in the Bio-drum, SUN-MAR ensures an odor free environment by engineering the air flow within the unit to maintain a partial vacuum at all times.

Air is drawn in by a fan, or on non-electric units by the vent chimney, over the evaporating chamber and up the vent stack. Not only does this evaporate excess liquid, but, by continuously pulling air in we ensure no smell escapes from the unit.

Evaporation is assisted on electric units by a thermostatically controlled heater in a sealed compartment underneath the evaporating chamber.
