Many innovative toilets are being conceptualized, built, and field tested these days. And while many of them have waste treatment incorporated into their functionality, they often don’t have that waste treatment occur on-site. Human interaction is often needed to transfer the waste from the toilet to either an off-site treatment facility, a large processor like the Janicki Omniprocessor, a mass-scale biodigester or, in the worst situations, to a nearby water source.
In this regard, we aimed to get rid of the reliance on human interaction entirely. With our toilet, waste is processed completely onsite within the unit itself, without it ever coming in contact with human hands. Our system doesn’t require piped-in water, a sewer connection, or outside electricity: it’s a completely closed and off-grid. And with its smaller footprint, it can be placed in many different locations around the world where much larger waste treatment solutions could never fit. Here’s how it works.
Waste treatment starts with the immediate diversion of liquid and solid waste. When anyone uses our toilet and flushes, the waste is washed down onto a slotted conveyer belt that separates the liquids from the solids.
Once that is complete, the conveyer belt engages and moves the solids into an actuator that mixes the solids into a slurry.
That mixture then gets pressed through a much smaller tube where it is heated, dried, and turned into small pellets. The pellets are then pushed into a tumbler to be dried further before being dropped into a chamber that contains a corkscrew.
This corkscrew then pushes the pellets uphill (drying them even further), before dropping them into an incinerator where they are burned to a fine ash. This ash can either be discarded safely, or used as fertilizer for feeding plants or crops.
Additionally, the heat generated from drying and incinerating the solid waste, produces energy that is harvested and stored to power the system itself.
Aside from clearing the ash out periodically (or occasional mechanical maintenance), our toilet system manages waste completely on its own. A closed system, providing total on-site treatment of human waste.
It is a clean, safe, healthier solution for anyone to use with dignity and confidence.
