Company and position

Loowatt builds high-quality closed-loop toilet systems for global markets. Loowatt has offices in London and Antananarivo (Madagascar) and projects in both countries plus The Philippines.

Our dynamic team, talented in design, engineering, and business development, has been building innovative sanitation technology since 2010. We take a hands-on approach, not shying away from life’s most difficult challenges. We have been funded by private investment, the Bill & Melinda Gates Foundation, and Innovate UK, among other funders.

Loowatt designs and manufactures patented off-grid toilet systems that are waterless, odourless and energy generating. In emerging markets, Loowatt is piloting household toilets linked to energy-generating systems and planning to expand coverage in the low-income urban communities. In the UK, Loowatt’s toilets serve off-grid events such as the Royal Windsor Horse Show and Wilderness Festival, and process waste into utility-run anaerobic digestion systems to produce power.

In 2020 Loowatt will begin the development of the next generation of Loowatt toilets both for the UK and emerging markets, with a focus on scaling up and outsourcing production to meet our increasing demands.
