Latest Patents
One of her latest patents is titled "Extraction of nitrogen from organic materials through ammonification by mixed bacterial populations." This invention provides a process for producing ammonia or ammonium from organic material by fermenting a medium that includes nitrogenous compounds suitable for conversion. The fermentation occurs under specific conditions to yield a product rich in ammonia or ammonium.
Another notable patent is "Biogas process with nutrient recovery." This invention outlines a method of two-phase anaerobic digestion that optimizes nitrogen status during the process. By monitoring the carbon to nitrogen molar ratio, the method improves the use of various feedstock materials and facilitates the monodigestion of a single feedstock. The process also includes the recovery of nitrogen and phosphorus from the digestate, which is then biogasified in the second phase.
