Clean, safe, waterless toilets that generate power too
PROVIDING SANITARY WASTE SOLUTIONS FOR ALL
For people throughout the developing world, poor sanitation has serious health implications.
THE BIG SOLVE
REINVENTING THE TOILET
The Loowatt waterless toilet seals waste in odor-inhibiting biodegradable film until it can be processed into usable biogas and fertilizer.
"With the Loowatt system we can ensure waste processing, treatment, and recycling is safe and efficient while also cutting down on water consumption and providing a useful by-product."
— Chris Holden, Head of Design
A worldwide toilet shortage
One-third of the global population, or 2.4 billion people, lack access to a toilet. In some places in the developing world, people are more likely to have a mobile phone than a toilet. It's difficult to provide clean, efficient toilet facilities in overpopulated developing areas. Because inadequate sewage and waste disposal are directly linked to the spread of many diseases, the need for better sanitation is a literal matter of life and death.
HOW IT WORKS
The Loowatt system automatically seals waste in odor-inhibiting biodegradable film each time the toilet is used.
The waste drops into a cartridge container, which is periodically emptied for treatment.
Treating the waste in an anaerobic digester kills pathogens, produces usable biogas, and (with some post-processing) creates safe fertilizer.
Because the system needs no water or external plumbing infrastructure, it can be installed almost anywhere.
Loowatt CEO Virginia Gardner first conceived of the core design as part of her master's thesis at London's Royal College of Art. With a Bill and Mellinda Gates Foundation Grant Loowatt launched a pilot project in Madagascar which will have 100 toilets by the end of 2016. Loowatt has also developed a system to provide toilets to festival sites in the UK. The company uses modeling, prototyping, and 3D printing for rapid iteration, even installing a 3D printer at its Madagascar location so it can print and install new and replacement components in hours.
Q & A
Why is the Loowatt waterless toilet revolutionary?
It combines a core innovative sealing technology with waterless toilet designs that are tailored to the needs of the communities they serve.
How does Loowatt address the challenge of improving global sanitation?
The Loowatt system collects and processes waste safely and efficiently, even in areas with no mains water supply, while providing a useful by-product.
LEARN MORE ABOUT LOOWATT
Loowatt has designed multiple versions of its toilet, all using the same core technology but tailored to meet the specific communities where they will be installed. The company is currently developing a smaller model intended for installation in individual homes.
Loowatt plans to increase the number of its toilets installed in Madagascar to 100, primarily by providing individual units for single households. The company is also installing an anaerobic digester at one of its sites to improve waste processing.
