The Gates Foundation funds work on sewage treatment

The Bill and Melinda Gates Foundation are investing in sustainable sanitation for developing countries. 

In the developing world, 2.5 billion people practice open defecation or lack adequate sanitation facilities; an additional 2.1 billion urban residents use facilities that do not safely dispose of human waste. 

Over a third of the world’s population don’t have access to functioning sanitation facilities or sewage treatment, however one of the main challenges is the treatment of sludge that is often collected but not properly disposed of.

Dr Hauser, Director of Water Services at TÜV SÜD stated, ‘Sustainable improvement of this situation requires innovative technologies that support decentralized solutions for sanitation facilities and wastewater treatment.’ 

One idea to combat this is the Omni Processor concept, this solution converts faecal sludge into biomass for generating electricity, potable and non-potable water for irrigation without any negative impact on the environment.

It’s hoped that in addition to certain technical requirements, further critical criteria for these technologies to prevail and spread throughout the world will also include factors such as operation and maintenance, occupational health and safety, emission values and guidelines for quality management systems.
