Background

Food waste, with 2.5 billion tons discarded globally each year, drives pollution and greenhouse gas emissions. Conventional disposal methods like landfilling and incineration are unsustainable and risky. This technology leverages microbial electrochemical systems (MES) to transform food waste into valuable biofuels and chemicals, delivering a sustainable, efficient solution for waste valorization while addressing critical needs for enhanced energy efficiency, process stability, and recovery effectiveness that current MES technologies face.

Technology Overview

Researchers at The Ohio State University have pioneered an advanced microbial electrochemical system (MES) that transforms food waste-including coffee grounds and dairy waste-into valuable biofuels such as butanol, ethanol, and acetone. This innovative electro-fermentation process boosts microbial efficiency under low voltage conditions, delivering higher product yields with reduced energy and cost. Fully scalable and compatible with existing fermentation systems, it’s a sustainable, adaptable solution for industrial-scale resource recovery.
