The Loowatt toilet uses a patented, simple and efficient sealing technology to contain human waste within biodegradable film, with a unique odor-inhibiting system. The waste is then stored in a cartridge for periodic emptying, which can be weekly or daily, depending upon level of usage and capacity requirements. The Loowatt sealing unit can be built into toilets of any shape, size and specification, using off-the-shelf parts and local materials to maximize value.
