This Chennai-based startup cleans wastewater.
And also generates electricity.
This is JSP Enviro.
They've developed a technology called BEADS (Bio-Electrochemical Anaerobic Digester System).
And this is based on microbial fuel cells.
In simple terms, they use special bacteria which can eat the pollutants inside the wastewater.
When these bacteria breaks down the waste, they also release electrons.
And BEADS captures some of those electrons using electrodes placed inside the system.
And that flow of electrons is what creates electricity.
Now, the electricity generated is not a lot.
But the most impressive part is - it doesn't require any chemicals, the process is carbon neutral, results in negligible sludge and it even cuts down operational costs by up to 50%.
And that's huge.
Because right now, India generates about 72 billion liters of sewage per day.
That's enough to fill nearly 29,000 Olympic sized swimming pools - every single day.
So, if JSP Enviro can scale their solution - it could help solve India's wastewater problem.
