The business case for sanitation in developing countries is testified by the thousands of small scale entrepreneurs springing up to tackle problems of open defecation and process faecal waste and urine.
Will these businesses be profitable and sustainable? Can they address the huge scale of the problem? Will they address the issues in rural areas as well as urban areas? These questions are much harder to answer.
The evidence from an event at the International Water Week leading up to the Sarphati Sanitation Award was mixed. The workshop Making Sustainable Business out of Sanitation, showed a high level of innovation and enthusiasm for businesses to address two of the most intractable public health and environment issues of our age – the 2.5 billion people who don’t have access to safe hygienic toilets and sanitation, and how to deal with human waste.
