As it turns out, there actually wasn't any waste paper in this village.
And the waste product from them after you extract the juice from the sugarcane is called "bagasse."
What we wanted to do was we wanted to find a way to harness this waste resource and turn it into a fuel that would be something that people could easily cook with, something like charcoal.
So you start with the bagasse, and then you take a very simple kiln that you can make out of a waste fifty five-gallon oil drum.
But now we have a way that's using an agricultural waste material to create a cooking fuel.
People can make their own cooking fuel from waste products.
It's easy to go down the wrong rabbit hole and waste a tremendous amount of time doing the wrong thing.
It's now more efficient for us to mine materials from our waste.
They're made in roadside workshops like this one by welders like Mohammed, who recover materials from the waste stream and use them to make all kinds of things, like dumbbells for working out out of old car parts.
If we manage it in a negligent or a shortsighted way, we will create waste, pollution, congestion, destruction of land and forests.
I've already described the problems of Beijing: pollution, congestion, waste and so on.
They need to know that they did not waste their life on meaningless tasks.
Not that I'm a bad teacher, but I've been studying and teaching about human waste and how waste is conveyed through these wastewater treatment plants, and how we engineer and design these treatment plants so that we can protect surface water like rivers.
So at North Carolina State University, we challenged our students to come up with a simple solution, and this is what they came up with: a simple, modified screw auger that can move the waste up from the pit and into a collecting drum, and now the pit worker doesn't have to go down into the pit.
Now, just as every cell requires nutrients to fuel it, every cell also produces waste as a byproduct, and the clearance of that waste is the second basic problem that each organ has to solve.
It takes up proteins and other waste from the spaces between the cells, it collects them, and then dumps them into the blood so they can be disposed of.
I mean, the brain is this intensely active organ that produces a correspondingly large amount of waste that must be efficiently cleared.
And yet, it lacks lymphatic vessels, which means that the approach that the rest of the body takes to clearing away its waste won't work in the brain.
So how, then, does the brain solve its waste clearance problem?
Well, that seemingly mundane question is where our group first jumped into this story, and what we found as we dove down into the brain, down among the neurons and the blood vessels, was that the brain's solution to the problem of waste clearance, it was really unexpected.
The CSF fills the space that surrounds the brain, and wastes from inside the brain make their way out to the CSF, which gets dumped, along with the waste, into the blood.
But what's interesting is that the fluid and the waste from inside the brain, they don't just percolate their way randomly out to these pools of CSF.
Instead, the CSF was pumped back into and through the brain along the outsides of the blood vessels, and as it flushed down into the brain along the outsides of these vessels, it was actually helping to clear away, to clean the waste from the spaces between the brain's cells.
And what's amazing is that no other organ takes quite this approach to clearing away the waste from between its cells.
Yet in the same animal, if we wait just a little while until it's gone to sleep, what we see is that the CSF is rushing through the brain, and we discovered that at the same time when the brain goes to sleep, the brain cells themselves seem to shrink, opening up spaces in between them, allowing fluid to rush through and allowing waste to be cleared out.
Our own research, now it's 2,000 years later, suggests that what's happening is that when the brain is awake and is at its most busy, it puts off clearing away the waste from the spaces between its cells until later, and then, when it goes to sleep and doesn't have to be as busy, it shifts into a kind of cleaning mode to clear away the waste from the spaces between its cells, the waste that's accumulated throughout the day.
Now, I've just talked a lot about waste clearance, but I haven't been very specific about the kinds of waste that the brain needs to be clearing during sleep in order to stay healthy.
The waste product that these recent studies focused most on is amyloid-beta, which is a protein that's made in the brain all the time.
So if sleep, then, is part of the brain's solution to the problem of waste clearance, then this may dramatically change how we think about the relationship between sleep, amyloid-beta, and Alzheimer's disease.
A series of recent clinical studies suggest that among patients who haven't yet developed Alzheimer's disease, worsening sleep quality and sleep duration are associated with a greater amount of amyloid-beta building up in the brain, and while it's important to point out that these studies don't prove that lack of sleep or poor sleep cause Alzheimer's disease, they do suggest that the failure of the brain to keep its house clean by clearing away waste like amyloid-beta may contribute to the development of conditions like Alzheimer's.
