  • Systems and method for biomass digestion
    Patent number: 8911627
    Abstract: Provided herein are systems and methods for biomass digestion and products formed thereof. The products include one or more biogases, U.S. Environmental Protection Agency classified Class A Biosolids, and pathogen reduced organic liquid fertilizer. Through the digestion of waste materials using sequential phases in an efficient digestion process, enhanced biomass conversion efficiency and improved output of products (in quantity and/or quality) are obtained with a significant reduction in dwell time in each phase.
    Type: Grant
