Loowatt: A value generating waterless toilet system

Elevator Pitch

Loowatt is a waterless toilet system that generates value. Our toilet uses a clean and odourless technology capturing human waste for conversion into energy and fertiliser—commodities that will create profitable business opportunities for waterless waste treatment and sanitation. Loowatt now has an operating pilot system in Antananarivo, Madagascar. We are also beginning a pilot in the UK, to be operational in 2014.

Product

The Loowatt toilet seals human waste into biodegradable polymer film for anaerobic digestion (AD). AD converts the waste and film into biogas, used directly as fuel or converted to electricity, and digestate, a nutrient-rich liquid that is further treated and sold as fertiliser.
Loowatt’s integrated approach creates a closed-loop value chain: toilet experience, AD performance optimization, energy generation, and fertilizer production. After years of practical experience testing product and system components at our London offices and laboratories, we have built a fully operational pilot in Antananarivo, Madagascar that successfully completes each link in the chain and has been serving customers since November 2012.



Why we are ecofriendly

Water Savings: A toilet flush in Madagascar uses 5 to 15 litres of water. A day’s use of one Loowatt toilet in Madagascar saves an estimated 400L of water that would be wasted in a public flush toilet.

Improved Local Health and Sanitation: Treating human waste with AD avoids contamination of nearby water streams and propagating diseases. Loowatt toilets, provide safe sanitation, whilst generating value from waste.

Positive Environmental Impact: Based on estimations from other AD projects in Africa, each digester would offset 5 tonnes of CO2 per year by creating renewable energy; for every 1 tonne of fertiliser produced by Loowatt, 4 tonnes of CO2 are offset compared with using artificial fertiliser (Berners-Lee, 2010).

CO2 avoidance–Energy: An estimated 95% of households in Madagascar depend on woody biomass for their household energy —resulting deforestation erodes the soil and damages Madagascar's rich biodiversity. Based on recent studies of small-scale biodigesters in East Africa, a single Loowatt Energy Unit digester would offset 5 tonnes of CO2 per year. Reaching 10% of the un-served toilet market in Madagascar would thus offset over 180 thousand tons of CO2 per year.

Increased productivity and connectivity: By producing energy, we can link our toilets to the growing array of energy-driven technologies that transform developing markets, such as mobile communication: powering communication hubs, charging devices, and enabling increased connectivity among people.

Food security: Much of the world’s food production relies on inorganic fertiliser, typically produced with vast amounts of non-renewable energy. The developing world is no exception, importing inorganic fertilisers and placing its food supply at the mercy of volatile global markets linked to oil prices. Human waste is a natural source of many of the required nutrients for growing food. As such, Loowatt’s fertilisers are organic and locally produced, contributing to improved food security for the World’s poorest.
