Leveraging biotechnology to convert methane to everyday products, including feed and food

String Bio envisions an ecologically sustainable world in which robust, cradle-to-cradle solutions provide the global population with cleaner ways of living. The company leverages methane as a source of carbon in order to manufacture green chemicals and food/animal feed ingredients. The products address multi-billion dollar markets. String is among a handful of companies worldwide — and the only Asian company — to successfully enable a methane-based value chain. Its proprietary platform (SIMP: String Integrated Methane Platform), leverages advances in synthetic biology, fermentation technology, chemistry, and process engineering to build a circular value chain.
String Bio's work has been recognized by several international awards and grants, including the Future Food Asia Award and the EnABLE startup awards in the Industrial Biotechnology sector. The company's first product to market, String Pro, is a high-quality protein that addresses the growing worldwide demand for sustainable protein. It is a cost-effective and high-performance protein for the aquaculture market. String is presently scaling its protein production.
