Toray Industries, Inc. has unveiled a groundbreaking immobilized-microorganism bioreactor technology designed to significantly enhance the efficiency and sustainability of chemical conversion processes. This innovative system is projected to slash energy consumption by an impressive 80–90% compared to traditional high-temperature, high-pressure methods, thereby drastically reducing operational costs and environmental footprint. The core of the technology involves a reactor packed with wood-based carriers, each coated with specific microorganisms. As a solution containing the target chemical flows through this packed bed, the microbial enzymes efficiently facilitate its conversion into desired products.Demonstration trials showcased remarkable efficacy, with conversion rates surpassing 99.5% for acrylonitrile. The bioreactor is capable of producing various essential chemicals, including acrylic, propionic, and acetic acids, which can then be fully biodegraded into carbon dioxide via activated-sludge treatment. A key feature is the reactor’s tightly sealed design, which not only boosts safety but also minimizes the loss of volatile substances, making it ideal for managing chemicals prone to airborne dispersion. Toray emphasizes the technology's versatility, noting that its approximately 500-species microbial library allows for customization—matching microorganisms and reactor designs to specific target chemicals and site conditions. This adaptability extends to both environmental remediation and the creation of valuable chemical products. Toray plans to further validate and refine the technology for commercialization, aligning with its broader commitment to addressing environmental challenges and fostering a sustainable economy through advanced material and process innovations.
