My name is Xenia Wirth, I'm a Ph.D. student at Georgia Tech, and I think
the world needs more renewable energy.
Right now in the U.S., one solution is burning biomass.
What is that?
It's plant waste —
Such as sawdust, grasses, trees, even garbage
But after we burn biomass we have ash leftover
I think we could use this
ash instead of throwing it away.
It turns out we can use ash to purify water,
just like a Brita pitcher.
I've seen success using it to take out lead and zinc and other heavy metals from water.
This is really a win-win because you have more
sustainable electricity and less waste in landfills.
Hooray biomass!
