The Creative Ways Innovators Are Recycling Air Pollution
To reduce air pollution, some innovators are making good use out of it.
We know the basics of what can be recycled and reused: paper, plastic, metal, glass. But there is an increasing host of waste that can now get repurposed thanks to technological advances.
Scientists have figured out, for example, how to use human poop—and that of horses, rhinos, and elephants—to power buses, rickshaws, and even homes. There’s technology now to turn restaurant grease into biofuel, ocean waste into shoes, and sewage into natural gas. Bill Gates has even proven that sewage can power the very system that turns sewage into—gulp—drinking water.
