IDEAS Alum: Safi Organics featured in MIT News!
“Safi [Organics] is decentralizing fertilizer production such that it can be carried out in rural villages for the first time,” Safi co-founder and chief technology officer Kevin Kung SM ’13, PhD ’17 says.
…
By the end of 2012, Kung had spent upward of three years on a research project to turn organic waste like crop residue from villages in Africa into charcoal for cooking fuel. Over the course of those efforts, Kung received support from the Priscilla King Gray Public Service Fellowship, the MIT Tata Center, the MIT Legatum Center, and the MIT IDEAS Social Innovation Challenge program.
Unfortunately, a series of failed pilot projects left him searching for a sustainable business model as his team of MIT students slowly disbanded. So Kung decided to use some of his funding to travel to Kenya in the summer of 2013 and partner with a local collaborator.
After making a job description, he was contacted by an agribusiness manager named Samuel Rigu. With Kung’s PhD work ongoing, he hired Rigu to run operations in Kenya as he returned to MIT at the end of the summer.
Soon after Rigu began heading the project, Kung began to appreciate his business mind.
Rigu learned that the charcoal they were making could also be used as fertilizer for growing crops if combined with other nutrients. The epiphany paved the way for localized fertilizer production that would offer advantages over the high cost of imported synthetic fertilizers.
Rigu knew the downside of cheap, synthetic fertilizers well: He’d grown up in a poor rural farming community and remembered his grandmother weeping as she spoke about the family’s land gradually losing its vitality.
Kung was skeptical about producing fertilizer, but Rigu convinced him to try out the idea with a small group of farmers. When harvest season came, some of the farmers using the formulation nearly doubled their yields (pH tests later showed the fertilizer helped combat the acidification caused by other farming techniques). Rigu and Kung watched with amazement as the extra income set off ripple effects in the community: Impoverished farmers used the extra funds to send their children to school and further improve their farms.
The founders decided to set up a company selling the soil formulation. They called it Safi Organics. In 2018, Kung received a grant from MIT’s Abdul Latif Jameel Water and Food Systems Lab (J-WAFS) to further the technology involved in Safi’s operations.
Today each of Safi’s production facilities can profitably provide fertilizer for thousands of farmers up to 20 miles away. Additionally, because Safi’s biochar is rich in inert carbon, when it’s used as fertilizer, it is sequestering carbon from the atmosphere.
Meanwhile, Kung’s PhD evolved into a project to build low-cost, portable biomass conversion systems to be deployed in rural areas like the small farms Safi works with. He says his involvement with Safi helped keep his PhD work relevant to real-world challenges.
“[Safi] started as a MIT project,” Kung says. “But we had to learn how to engage local partners and recognize that sometimes they are going to become the champions of these initiatives, not necessarily us, and they’ll have the final say in the direction of things.”
