Waterless hygenic toilet

Abstract

A portable, self-contained toilet is provided that does not require water, and produces its own energy without the need for an external source of power. The toilet includes and external housing for providing protection from environmental elements to components of the toilet and to human users of the toilet. A toilet bowl directs liquid and solid waste into a collection hopper. Once the hopper is full, a turntable or other rotary device is indexed to advance the waste filled hopper to an intermediary position. From there, the hopper is moved onto a burner, where the collected human waste is separated into liquid and solid waste. As a result of heating, the liquid waste turns to steam and is removed from the hopper, collected, filtered and the resulting distilled water stored. The remaining solid bio-fuel may be removed and disposed of or used as needed. Solar panels and batteries provide power to the toilet may be replaced with an alternate energy source providing the same inherent energy requirements to the process.

Description

FIELD OF THE INVENTION[0001]The invention relates to portable, self-contained toilets, and specifically relates to a portable, self-contained toilet that does not require water, and produces its own energy without the need for an external source of power.BACKGROUND OF THE INVENTION[0002]An estimated 2.6 billion people—about 40 percent of the world's population—do not have access to sanitation. In such situations, human waste piles up without access to functioning toilets contaminating drinking and bathing water and spreading disease. Children often suffer the most with 1.5 million dying worldwide each year from poor sanitation. There are substantial obstacles to fixing the problem. In many developing countries, there is no sewer infrastructure and water is scarce.[0003]Creating sanitation infrastructure and public services that work for everyone, including poor people, and that keep waste out of the environment is a major challenge.

AI Technical Summary

Benefits of technology

The present invention provides a portable, self-contained waterless toilet that does not require an external power source. The toilet includes a housing for protection, a waste collection means, a separating means for separating liquid and solid waste, a capturing means for collecting the separated liquid, a filtering means for recycling the liquid, a storing means for the separated liquid, and a removal means for the solid waste. The toilet is controlled by a programmable logic controller and may include pneumatic cylinders, turntable, and support blocks for the waste collection means. The waste collection means may include a urine only toilet and a urine holding tank for urine recycling. The toilet is portable, self-contained, and can be easily moved and installed.

Problems solved by technology

In such situations, human waste piles up without access to functioning toilets contaminating drinking and bathing water and spreading disease.

Children often suffer the most with 1.5 million dying worldwide each year from poor sanitation.

There are substantial obstacles to fixing the problem.

In many developing countries, there is no sewer infrastructure and water is scarce.

Creating sanitation infrastructure and public services that work for everyone, including poor people, and that keep waste out of the environment is a major challenge.

The toilets, sewers, and wastewater treatment systems used in the developed world require vast amounts of land, energy, and water—and they are expensive to build and maintain.

Existing alternatives that are less expensive are often unappealing because of impractical designs or because they retain odors and attract insects.
