For more than two years, Kohler Co. has collaborated with Caltech in the development of a photovoltaic toilet as part of the Reinvent the Toilet Challenge, hosted by the Bill & Melinda Gates Foundation. In response to this successful project, the Gates Foundation recently approved a two-year grant to Kohler to design and fabricate five closed-loop flush toilet systems for field testing in developing world locations without adequate sanitation.
With the recent announcement from India’s Prime Minister Narendra Modi, promising through his Swachh Bharat Abhiyan (Clean India campaign) to build 100 million toilets across the country, global interest in the developing world’s sanitation conditions is higher than ever.
