The Other Dark Matter: The Science and Business of Turning Waste into Wealth and Health

Product Description

Grossly ambitious and rooted in scientific scholarship, The Other Dark Matter shows how human excrement can be a life-saving, money-making resource—if we make better use of it.

The average person produces about four hundred pounds of excrement a year. More than seven billion people live on this planet. Holy crap!

Because of the diseases it spreads, we have learned to distance ourselves from our waste, but the long line of engineering marvels we’ve created to do so—from Roman sewage systems and medieval latrines to the immense, computerized treatment plants we use today—has also done considerable damage to the earth’s ecology. Now scientists tell us: we’ve been wasting our waste. When recycled correctly, this resource, cheap and widely available, can be converted into a sustainable energy source, act as an organic fertilizer, provide effective medicinal therapy for antibiotic-resistant bacterial infection, and much more.

In clear and engaging prose that draws on her extensive research and interviews, Lina Zeldovich documents the massive redistribution of nutrients and sanitation inequities across the globe. She profiles the pioneers of poop upcycling, from startups in African villages to innovators in American cities that convert sewage into fertilizer, biogas, crude oil, and even life-saving medicine. She breaks taboos surrounding sewage disposal and shows how hygienic waste repurposing can help battle climate change, reduce acid rain, and eliminate toxic algal blooms. Ultimately, she implores us to use our innate organic power for the greater good. Don’t just sit there and let it go to waste.

Review

“A take on waste that’s anything but wasteful—it’s a fascinating dig into the history and science of handling human excrement. . . . Equally remarkable are Zeldovich’s sections on the development and evolution of wastewater treatment plants. . . . Zeldovich is at home with an awkward subject, making for a grossly engrossing and vivid survey. Readers won’t take the ‘flush and forget’ mindset for granted again.”

Publishers Weekly

“This is some good shit, people. Not only entertaining, but deeply important. Everyone with a colon should read this book. Centuries back, people knew the value of shit. In countries with poor soil, human waste was like gold: people stole it, paid their rent with it, and gave it as gifts. Today, keeping it out of our waterways is our best hope for defusing what Zeldovich calls the Great Sewage Time Bomb. She is an ideal guide to this ridiculously fascinating world.”
— Mary Roach, author of Stiff: The Curious Lives of Human Cadavers

“Zeldovich shows to dazzling effect how a famously difficult subject—the often peculiar scientific history of human waste—can become an engrossing tale. The story is enlightening, surprising, occasionally enraging—and wholly worth your time.”
— Deborah Blum, Pulitzer Prize–winning author of The Poison Squad

“Zeldovich shows that excrement can be useful, profitable, and anything but waste, and does this with warmth, curiosity, and humor. This book is a great companion should you wish to journey to the rich and still underexposed world of shit (and you should).”
— Rose George, author of The Big Necessity: The Unmentionable World of Human Waste and Why It Matters

“Here is an indispensable book about what we might call the Anthro-poo-cene. Humanity’s current collision course with nature has everything to do with energy and how we abuse it—including the human waste products of our metabolic bodies. This lively and entertaining history is also full of innovative ways people are finally dealing with their you-know-what.”
— Mary Ellen Hannibal, author of Citizen Scientist: Searching for Heroes and Hope in an Age of Extinction

“Who knew our poop could be so fascinating and important? In her brilliantly reported and written new book, Zeldovich shows that now more than ever the health of humanity and the rest of nature depends on ho
