Ecological Urinal

The Ecological Urinal was created as a solution for places like Uganda's capital, Kampala, where on average, 1,000 people have to share the same toilet. The make-shift urinal is an adaptable funnel that connects to locally available jerrycans. It collects urine, stores it in a sanitary way, and turns it into a high-quality fertilizer. It costs only $3

Sabine Schober Toilet

The Sabine Schober toilet uses the Terra Preta Sanitation technology, which treats pee and poo by mixing it with charcoal to produce highly fertile soil for reforestation. It is also unique because it can be used in both the sitting and the squatting position. The toilet can be built using three robust components made of sanitary ceramic on the outside and a plastic container on the inside that collects pee and poo for only about $70.

Can be used where there is sufficient water supply and means of dealing with waste water. Tech level is higher than straight drop toilets. Manufacturing and internal mechanism is complex. Viability in low for the poor and higher/high for wealthier households.

Urine Diverting Flush Toilet (UDFT)

The Urine Diverting Flush Toilet (UDFT) is similar in appearance to a Cistern Flush Toilet except for the diversion in the bowl. The toilet bowl has two sections so that the urine can be separated from the feces. Both sitting and squatting models exist. Urine is collected in a drain in the front of the toilet and feces are collected in the back. The urine is collected without water, but a small amount of water is used to rinse the urine-collection bowl when the toilet is flushed. The urine flows into a storage tank for further use or processing, while the feces are flushed with water to be treated. Most likely to be used in high-resource setting in new constructions and where there is significant focus on sustainable sanitation methods. Only used in a limited number of locations in the developed world.

SaTo Pan

The SaTo pan was developed by American Standard. It is a low-cost (2-5 USD per unit) toilet pan that relies on a physical shutter with a mechanical seal and water to separate the user and vault contents. When sufficient material or flush water is deposited into the pan, the mechanical shutter opens, allowing the waste to fall into the vault, then the shutter closes again. The shutter blocks the view of the vault contents, prevents odors from escaping, and keeps flying insects from contacting the waste and transmitting diseases. While the SaTo Pan does rely on water for flushing, the design is well optimized and uses only 1/2 liter of water per flush.

A urine-diverting dry toilet (UDDT) is a type of dry toilet with urine diversion that can be used to provide safe, affordable sanitation in a variety of contexts worldwide. Through the separate collection of feces and urine without any flush water, many advantages can be realized, such as odor-free operation and pathogen reduction by drying. Some are used in conjunction with resource recovery schemes.

save! Toilet

The latest urine-diverting toilet, known as “save!”, is based on an innovative idea from the designer Harald Gründl of the Austrian design studio EOOS. It dispenses altogether with a valve, which had always been required to date. The toilet is designed in such a way that urine drains correctly almost automatically, by the force of gravity, while most of the flushwater “overshoots” and enters the sewer system. The innovation is the so-called urine trap, which conveys urine across the inner surface of the toilet bowl into a concealed outlet, working purely by surface tension. This phenomenon is known as the teapot effect

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.

Ecological Sanitation is an approach to sanitation provision which aims to safely reuse excreta in agriculture. It desires to "close the loop" mainly for the nutrients and organic matter between sanitation and agriculture. One of the aims is to minimize the use of non-renewable resources. When properly designed and operated, ecosan systems provide a hygienically safe system to convert human excreta into nutrients to be returned to the soil, and water to be returned to the land.

Cesspool or Pit

A cesspit, or cesspool is a tank pit used for the temporary collection and storage of sewage or waste. The pit is sometimes lined with bricks or concrete and mostly covered with a slab. In case the pit is constructed water-tight, it needs to be emptied frequently. When the pit is not tight, liquids leached out if soil conditions allow, while solids decay and collect in the base. The treatment effect of a cesspit is very low. Emptying can result in high operation and maintenance costs. Cesspits which allow soil infiltration require less frequent emptying but groundwater pollution can occur

Fossa Alterna (double pit latrine)

The Fossa Alterna is a short cycle alternating, waterless (dry) double pit technology. Compared to the double VIP which is just designed to collect, store and partially treat excreta, the Fossa Alterna is designed to make an earth-like product that can be used as a nutrient-rich soil conditioner.

Composting Toilet

Composting toilets are toilet systems comprised of a superstructure, a pan or slab, and a vault or pit in which feces or excreta fall together with cleansing material (the composting chamber). Dry organic material such as sawdust is added to adjust moisture content and C/N ratio in order to obtain optimum conditions for thermophilic composting. Composting toilets can be used to treat both excreta and organic household or garden waste and to transform it into a valuable soil amendment. Composting toilets rarely work. Users misuse them and the composting chamber doesn’t get hot enough or remain hot enough for composting and treatment to occur. UD Composting toilets are better but are still problematic.
