  • Patent number: 11440828
    Abstract: The present invention relates to a method of treating sludge containing phosphorus, ammonia and magnesium and enhancing the dewaterability of the sludge. The sludge is directed into a biological fermenter operated under anaerobic conditions. By controlling the temperature of the sludge in the fermenter or the hydraulic retention time of the sludge in the fermenter, phosphorus, ammonia and magnesium is released from the solids in the sludge into a liquid forming a part of the sludge. Sludge from the fermenter is subjected to a solids-liquid separation process that produces a concentrated sludge and a liquid. The concentrated sludge or separated solids is directed to a thermal hydrolysis reactor that thermally hydrolyzes the concentrated sludge. After thermally hydrolyzing the concentrated sludge, the concentrated sludge is directed to an anaerobic digester that anaerobically digests the concentrated sludge.

  • Patent number: 11359174
    Abstract: The invention describes a methodology for production of a secondary extra-particle fungal matrix for application as a mycological material, manufactured via a Type II actively aerated static packed-bed bioreactor. A pre-conditioned air stream is passed through a substrate of discrete elements inoculated with a filamentous fungus to form an isotropic inter-particle hyphal matrix between the discrete elements. Continued feeding of the air through the substrate of discrete elements and isotropic inter-particle hyphal matrixes develops an extra-particle hyphal matrix that extends from an isotropic inter-particle hyphal matrix in the direction of airflow into a void space within the vessel.

  • Patent number: 8956853
    Abstract: A method for degumming an oil composition comprises the steps of (a) providing an oil composition containing a quantity of phospholipids, (b) contacting said oil composition simultaneously with one or more phospholipase A enzymes and one or more phospholipase C enzymes, under conditions sufficient for the enzymes to react with the phospholipids to create phospholipid reaction products, and (c) separating the phospholipids reaction products from the oil composition, the remaining oil composition after the separation being a degummed oil composition, whereby during step (b) the reaction of said one or more phospholipase A enzymes proceeds at a faster rate than it would in the absence of said one or more phospholipase C enzymes.

    Abstract: Methods and products for spill response management also providing bioremediation of specific substrates such as protein, starch, carbohydrates, hydrocarbons, fats and greases through superior enzymatic activity in both aerobic and anaerobic environments with one product. In one illustrative embodiment, a product may include coir in a proportion of from about 85% to about 99% and a suitable microbe for initiating bioremediation in an appropriate form in a proportion of from about 20% to about 1%, by weight. Methods of using a product may include absorbing spilled fluid with the product then disposing of the product with the absorbed fluid where the microbe will perform bioremediation. This may allow the absorption (cleanup) of commonly used hazardous and non-hazardous chemicals in residential, commercial and industrial applications and the peace of mind of using a safe, sustainable, environmentally friendly, landfill safe product.
