AD Model: Improving a Model of On-Farm Anaerobic Digestion for Integration with Manure Processing
Cornell PRO-DAIRY is part of a project funded by the Rapid Advancement in Process Intensification Deployment (RAPID) Manufacturing Institute, to evaluate the economic and technical feasibility of a system using biorefineries in NY State, combining anaerobic digestion (AD), hydrothermal liquefaction (HTL), and a Biomethanation Power to Grid (P2G) systems to process agricultural and food wastes. This becomes important with the newly passed food scraps donation and upcycling bill in NYS that requires producers that generate more than two tons of food waste per week to divert its wastes from being landfilled if they are within 25 miles of appropriate waste handling facilities. These wastes would be viewed as a resource for energy and nutrient recovery and can be harnessed through a combination of process technologies that can produce a range of renewable bio-products such as renewable natural gas (RNG), biocrude oil and hydrochar. The sale of co-products provide revenue streams, which can be used to offset the capital costs of purchasing and installing the biorefinery system.
