A multi beneficiary two-fold solution to sanitation.
Self cleaning toilets combined with utilizing human waste into recyclable usable energy through existing bio-fuel models could be the sustainable solution to tackle sanitation in India.
Part 1: Self cleaning toilets for sanitation.
Many public toilet facilities in India are in extremely poor conditions and preliminary research suggests the following key reasons of why:
- Cost of maintenance
- Unappealing conditions to use
- And for many years - no negative stigma attached to open defecation
The first part of this proposal is therefore to implement self cleaning toilet facilities in these public areas, perhaps near slums or markets - essentially areas of high density and human traffic such as Shivaji Nagar, a Mumbai slum where it is estimated that the ratio of toilets to people is 1 to 300.
Utilizing a new ultraviolet technology similar to what is currently being tested by Boeing, to make the public facilities more inviting and comfortable for users. The toilets would automatically close their cubicle doors and then be sanitized after each use killing 99.99% of bacteria on exposed surface areas. Jamie Childress, Boeing’s Research and Technologist explains “It is the resonate frequency of the molecular bonds on the outside of microbes.. so every virus, every bacteria in it literally makes them explode”. The UV light used is different to the rays that cause sunburn - it is much shorter frequency and does not cause harm to humans.
We suggest that the UV in each cubicle is powered through batteries which are energized by solar panels installed on the roof of the public toilets during the day and the waste from each pit is flushed by rainwater and suction.
Part 2: Human waste for bio-fuel energy.
Air pollution is recognized as a major environmental problem contributing as the largely as a cause of poor sanitation and a lack of clean drinking water. The emissions are only increasing due to rapid growth in traffic outpacing the adoption of tighter controls on emissions from vehicles. To address this, the Indian government has announced a national policy on the planning and use of bio-fuels as transport fuels.
In support of this, we are proposing that the human waste gathered from these public self cleaning toilets are then broken down using the Anaerobic Digestion process to produce bio-gas. The bio-gas can be used as fuel directly or further be combined with heat and power to generate electricity. Harnessing the power of poop and this recycling innovation is already being utilized in Kenya, UK, USA and Australia for the powering of transportation and a source of renewable energy.
The marketable approach.
We are proposing that bio-fuel industry players in India such as Tata Power, Reliance Power, NTPC and Power Grid Corp,to invest in our solution and work with Boeing and the likes of Slamson Ghana and Beijing Century Green Environmental Engineering & Technology Ltd for the multiple benefits of impacting the country’s sanitation, reducing pollution emissions as well as utilizing a renewable source of energy.
