  • Managing Sludge Mountains: What Beijing Can Learn From Brazil

    ›
    China Environment Forum  //  March 2, 2018  //  By Carl Hooks & David Bachrach

    This is the second article in a series of case studies of innovative wastewater treatment plants in Brooklyn and Brazil from China Environment Forum and Circle of Blue’s Choke Point China initiative, which since 2010 has been exploring challenges and solutions to water-energy-food confrontations in the world’s most populated country. Read the first article here.

    Just days before the 2016 Summer Olympics began in Rio de Janeiro, the Brazilian city faced an unsavory problem: how to handle its overwhelming sewage. Nearly half of Rio’s municipal wastewater flowed untreated into Guanabara Bay, where the waters were so polluted by sludge that direct contact was deemed a health hazard to Olympic athletes.

    This is the first article in a series of case studies of innovative wastewater treatment plants in Brooklyn and Brazil from the China Environment Forum and Circle of Blue’s Choke Point China Initiative, which since 2010 has been exploring challenges and solutions to water-energy-food confrontations in the world’s most populated country.

    Chinese cities are being encircled by untreated sludge—a pungent, viscous mixture of human excreta and stormwater runoff. Four years ago in Beijing, trucks loaded with untreated sludge from the city’s largest wastewater treatment plant were illegally dumping mountains of sludge in the outskirts of the capital as “free fertilizer” for peri-urban farms. Similarly, in the southern China city of Guangzhou, disposing toxic sludge into the nearby river required nothing more than a hired boat. From the far western desert city of Urumqi to the eastern metropolis of Shanghai, more and more of China’s cities are struggling to manage mountains of sludge and municipal waste, as well as floods of wastewater and stormwater runoff.
