Hertz Fellows Receive Gates Grant to "Reinvent the Toilet"

Bill & Melinda Gates Foundation Honors Hertz Foundation Fellows; Biochar Group One of Eight University Teams to “Reinvent the Toilet”

Young Leaders to Apply Biochar Innovation to Sanitation Solutions in Nairobi, Kenya


Livermore, CA—19 July 2011—Fellows of the Fannie and John Hertz Foundation helped form a team that has been selected as grant recipients to participate in the Bill & Melinda Gates Foundation “Reinvent the Toilet Challenge” announced at the AfricaSan conference in Rwanda as part of more than $40 million in new investments launching its Water, Sanitation, & Hygiene strategy.

The winning “Biochar Group” is a volunteer collaboration including Hertz Fellows from MIT, Caltech, the University of California, Berkeley, and Stanford University. The group is one of eight winning teams from a field of 22 universities invited to compete in the Gates Foundation challenge to develop a 21st century toilet without links to water, energy, or sewer lines that costs users under $0.05 a day.

The award supports the work of the Biochar Group in the production of crucial biochar that can help reverse carbon depletion in our soils. That work will be applied to transform the disposal and sterilization of sewage in a million-person slum within the city of Nairobi, Kenya in conjunction with Sanergy, an MIT startup working in Africa on sanitation and renewable energy. The awards will be announced July 19 at a major conference in Rwanda.

"We are honored to see our Fellows participate in the Bill & Melinda Gates Foundation effort, which aims to improve the lives of 2.6 billion people without adequate sanitation on our planet,” said Dr. Jay Davis, Hertz Foundation President. “The Hertz Fellows have built a vibrant community to support and inspire one another. Good things come from that collaboration and the Biochar Group has been one of the most exciting. We’re doubly grateful to have our work recognized by the Bill & Melinda Gates Foundation."

Biochar is a high grade of charcoal formed in a low-oxygen environment. Instead of burning or combustion, pyrolysis converts biomass into biochar in the range of 450 to 600 degrees Celsius. This principle will be applied to the transformation of sewage in third world countries.

The Hertz Foundation Biochar Group has worked for two years to build four generations of machines that create biochar to sequester carbon in the soil. “Each year 60 gigatons of agriculturally fixed carbon rots and turns back into carbon dioxide,” said Dr. Brian Von Herzen, Executive Director of the Climate Foundation, Hertz Fellow (1980) and director of the Biochar Group. “By converting just ten percent of the fixed carbon into biochar, we could actually capture and sequester most of man’s atmospheric carbon dioxide emitted each year.

The Biochar Group’s efforts will be directed by Dr. Von Herzen and by Professor Reginald Mitchell at Stanford University, the home university for this year’s project.

“To address the needs of the 2.6 billion people who don’t have access to safe sanitation, we not only must reinvent the toilet, we also must find safe, affordable and sustainable ways to capture, treat, and recycle human waste,” said Sylvia Mathews Burwell, president of the Global Development Program at the Bill & Melinda Gates Foundation. “Most importantly, we must work closely with local communities to develop lasting sanitation solutions that will improve their lives.”

The Biochar Group was formed in 2009 when Dr. Von Herzen spoke at a community-building retreat for Hertz Fellows, supported by Hertz Fellow Ray Sidney. The Biochar Group won Berkeley’s 2010 Venture Lab competition at the Center for Entrepreneurship and Technology with the help of Berkeley graduate students, Andrew North and Matt Beres. The Group participants include John Frank, Tony Miller, Matt Lucas and Shannon Yee, with the support of Ray Sidney, Louis Lerman and The Climate Foundation.

About the Hertz Foundation

For nearly half a century, the Fannie and John Hertz Foundation has focused on empowering young applied scientists and engineers with the freedom to innovate in their doctoral research. The Hertz Foundation has provided the nation’s most generous PhD fellowships to nearly 1100 gifted young men and women. The highly competitive selection process includes a comprehensive written application, four references, and two rounds of technical interviews by recognized leaders in applied science and engineering. In addition to supporting the Fellows in their graduate education, the Foundation provides unique seminars, workshops and symposia that take place away from their campus environments. These gatherings expose the in-school Fellow to national leaders and researchers, many of whom are alumni Fellows of the Foundation.
