(EP507793-A1)      Composting toilet has a system for receiving and collecting only liquids, and also a heat-insulated rotary drum which receives only solid waste for transfer to a collection container. Solid waste enters the drum via a hole in a wall of the toilet bowl and a hole in the drum, the latter being ventilated.    ADVANTAGE -   Solids for composting are not mixed with liqs. prone to disturb composting process.

(US5303431-A)      Composting toilet comprises (a) an outer shell; (b) a rotatable drum forming composting spaced; (c) collection for solid toilet waste in (b); and (d) a toiler seat upon (a) having liq. sepn. for conducting liqs. separately from solid waste.    Toilet also comprises (e) a ventilation duct attached to the outer shell so (b) is thermally insulated; and (f) a stationary wall attached to the interior of the outer shell forming a ventilation passage.    ADVANTAGE -   Toilet seat is adapted to allow solid waste to fall through its inlet opening in the lower part of (f) directly onto the inside surface of (b), and liqs. to flow outside (b).    (RU2037478-C1)      Composting toilet has a system for receiving and collecting only liquids, and also a heat-insulated rotary drum which receives only solid waste for transfer to a collection container.
