Pongamia trees grow where citrus once flourished, offering renewable energy and plant-based protein

An ancient tree from India is now thriving in groves where citrus trees once flourished in Florida, and could help provide the nation with renewable energy.
As large parts of the Sunshine State’s once-famous citrus industry have all but dried up over the past two decades because of two fatal diseases, greening and citrus canker, some farmers are turning to the pongamia tree, a climate-resilient tree with the potential to produce plant-based proteins and a sustainable biofuel.
For years, pongamia has been used for shade trees, producing legumes — little brown beans — that are so bitter wild hogs won’t even eat them.
But unlike the orange and grapefruit trees that long occupied these rural Florida groves northwest of West Palm Beach, pongamia trees don’t need much attention.
Pongamia trees also don’t need fertilizer or pesticides. They flourish in drought or rainy conditions. And they don’t require teams of workers to pick the beans. A machine simply shakes the tiny beans from the branches when they are ready to harvest.
Terviva, a San Francisco-based company founded in 2010 by Naveen Sikka, then uses its patented process to remove the biopesticides that cause the bitter taste, making the beans suitable for food production.
“Florida offers a rare opportunity for both Terviva and former citrus farmers. The historical decline of the citrus industry has left farmers without a crop that can grow profitably on hundreds of thousands of acres, and there needs to be a very scalable replacement, very soon,” Sikka told The Associated Press. “Pongamia is the perfect fit.”
