Microbial Fuel Cell Latrine

low-cost, low maintenance toilet that directly converts the potential energy contained in human waste (human excreta) into electricity, while simultaneously removing the organic matter and nutrients that can pollute ecosytems and allow pathogens to persist in water sources.

University of Toronto Smoldering Toilet

he Toronto Toilet uses a sand filled and UV-ray disinfecting chamber to process liquid waste and a smolder chamber, similar to a charcoal barbecue, to incinerate solid waste that has been flattened and dried in a roller/belt assembly. The toilet is sustainable, easy to use and one that processes waste while protecting the community from contamination. The equipment and processes are designed to be easily repaired and managed in a remote community by people with limited resources and training.

Anaerobic Digestion Pasteurization Latrine (household system)

The Anaerobic Digestion Pasteurization Latrine (ADPL) is a self-contained and energy neutral on-site sanitation system using anaerobic digestion of fecal sludge to generate biogas and then uses the biogas to pasteurize the digester effluent at 65–75°C to produce a safe effluent that can be reused locally as a fertilizer.

BioFil Digester

Biofil Digester is an affordable, on-site fecal waste treatment system that works with most toilet systems. Our product replaces existing systems at a much lower cost of $ 300 - $ 600. It requires no prior infrastructure to install. This compares very favourably with septic tanks and central sewers which require investments of thousands and hundreds of thousand respectively. In addition to the Biofil Digester, our new innovation which makes use of waste water for flushing makes it possible for people without safe sanitation to afford decent sanitation.

NEWgenerator

The NEWgenerator uses a multistage disinfection process. A fine-pore microscopic membrane filter traps bacteria and viruses.Clean water that passes through is then disinfected with chlorine, similar to municipal drinking water. The recycled water can be used for toilet flushing in the sanitation facilities, thereby drastically cutting down on water demand, especially during times of drought. The water can also be used for irrigation.

Sol-Char Toilet

The Sol-Char Toilet utilizes concentrated solar power (CSP) to convert human waste into char, an odorless product that can be used as fuel or soil-amendment.  A waterless, self-contained toilet that functions off-the-grid. Concentrated sunlight is delivered to fiber optic bundles located at the focus of parabolic concentrators illuminating the inner collection container and disinfecting the waste though conduction, convection, and radiation heat transfer. The reactor is designed to achieve high temperatures (300C to 750C) and produces a safe and useable product

Firelight Toilet

The Firelight Toilet works by drying fecal material via boiling. The steam that is generated then undergoes a pressure and temperature increase by a compressor and is used as the heat source for the drying process. The dried biomass is then metered into a controlled fire where it is burned, creating heat to kill pathogens and boil water, which is then utilized within a steam engine Rankine cycle to generate electricity.

Nanomembrane Toilet

The Nano Membrane Toilet will be able to treat human waste on-site without external energy or water. It is designed for single-household use (equivalent to 10 people) and will accept urine and faeces as a mixture. The flush uses a unique rotating mechanism without using any water whilst simultaneously blocking odour and the user’s view of the waste.

Aqua-privy. An aqua-privy has a watertight tank immediately under the latrine floor. Excreta drop directly into the tank through a pipe. The bottom of the pipe is submerged in the liquid in the tank, forming a water seal to prevent escape of flies, mosquitos and smell. The tank functions like a septic tank.

Our Dutch Latrine Bag (DLB) offers a simple and effective solution for this pollution problem. The DLB is a large strong plastic bag placed into the pit latrine preventing human waste to pollute the groundwater table. In effect the DLB delivers the opportunity to close the sanitation cycle and re-use human waste for agricultural and biogas applications.
