About
EF Polymer is a deep-tech startup that develops 100% organic, fully biodegradable superabsorbent polymers (SAP) made from agricultural residues such as orange and banana peels. Founded in India and nurtured at the Okinawa Institute of Science and Technology (OIST), the company addresses global water scarcity and agricultural sustainability challenges by upcycling organic waste into high-performance soil additives that help farmers conserve water and build climate resilience. EF Polymer's nature-based materials reduce reliance on petroleum-derived SAPs and support a circular economy model. The company has won numerous international awards including Forbes Asia 100 To Watch, the Ministry of Environment Japan Environmental Startup Award, and a G20 Digital Innovation Alliance Summit 2nd place. It operates globally with presence in Japan, India, and the United States.
