TOKYO -- An Indian social reformer who has worked to end an age-old stigma associated with a lack of proper toilets says he is confident that his design can save over 2 billion people suffering from poor sanitation around the world.
Bindeshwar Pathak, founder of Sulabh International, has worked for 50 years to solve sanitation problems in India. He invented a composting flush toilet that his nongovernmental organization has installed in 1.5 million homes.
