The WooWoo GT 120 is a high-capacity batch composting system built for off-grid cabins, shepherd's huts, allotments, forest schools, and glamping pods. No urine separator, no chemicals, no mains connection required — just a simple, robust system that handles solid and liquid waste together in a sealed composting chamber.
The "batch" approach means you swap between two containers: one in use, one composting. Each 120-litre container holds approximately 200 solid uses before you rotate. The capillary base regulates moisture automatically — draining excess liquid as leachate, drawing it back if the compost dries out.
