Introduction
Toray Industries has developed a new immobilized-microorganism bioreactor technology that significantly reduces energy consumption in chemical conversion processes. This innovation promises to cut energy use by 80% to 90% compared to conventional methods, which typically require high temperatures and pressures.
Technology Details
The technology involves immobilizing specific microorganisms on wood-based carriers within a reactor. This setup allows microbial enzymes to efficiently convert target chemicals into desired products through continuous contact with an aqueous solution. The reactor's sealed design is particularly effective for volatile substances, minimizing losses and enhancing safety.
Demonstration and Applications
An in-house trial using acrylonitrile demonstrated a conversion efficiency of over 99.5%, producing organic acids like acrylic, propionic, and acetic acids. These products can be further broken down to carbon dioxide when combined with activated-sludge treatment. The technology is adaptable to various chemicals by customizing the microorganisms and reactor structure, drawing from a library of around 500 microbe species.
Future Plans
Toray aims to advance technical verification and operational design at both internal and external production sites to commercialize this energy-conserving solution. The company is committed to addressing environmental challenges and contributing to a sustainable economy through its materials technologies.
