  • Patent number: 9834483
    Abstract: Syrup produced in a lignocellulosic biomass fermentation process is used as a binder for soil conditioning materials to make an agricultural composition that is easily handled and applied. The syrup binds powdery soil conditioning materials such as lime and gypsum to form pellets or granules.
    Type: Grant
    Filed: October 5, 2016
    Date of Patent: December 5, 2017
    Assignee: E I DU PONT NEMOURS AND COMPANY
    Inventors: Steven W Ogle, Stephanie C. Vrakas, David William Wood
  • Patent number: 9725363
    Abstract: A fuel made from co-products derived from a lignocellulosic biomass fermentation process is used to fuel a cement production process. Filter cake and syrup co-products are mixed and dried, then burned in a cement kiln to create the temperatures needed for cement production.

  • Publication number: 20160050926
    Abstract: Disclosed is an insecticidal composition comprising by weight based on the total weight of the composition: (a) from about 0.25 to about 25% of one or more anthranilic diamide insecticides; (b) from about 2.5 to about 25% of a poly(lactic add) polymer component having a water dispersability of at least about 5% by weight at 20° C. and an average molecular weight ranging from about 700 to about 4,000 daltons; wherein the ratio of component (b) to component (a) is about 1:1 to about 1:10 by weight; and (c) from about 20 to about 50% of a composition comprising either (i) a poly(lactide-co-glycolide) copolymer and a methyl poly(ethylene glycol) copolymer, or (ii) an acrylate/methacrylate-based polymer or copolymer and a methyl poly(ethylene glycol) copolymer; wherein the methyl poly(ethylene glycol) copolymer has a water solubility of at least about 5% by weight at 20° C.

  • Patent number: 9149039
    Abstract: Disclosed is an insecticidal composition comprising by weight based on the total weight of the composition: (a) from about 9 wt % (weight percent) to about 82 wt % of one or more anthranilic diamide insecticides; (b) from about 9 wt % to about 82 wt % of a triblock copolymer component having a water solubility of at least about 5% by weight at 20° C.; wherein the ratio of component (b) to component (a) is about 1:10 to about 10:1 by weight; and (c) from about 9 wt % to about 82 wt % of a polymer crosslinking agent having water solubility of least about 5% by weight at 20° C.; wherein the ratio of component (b) to component (c) is about 1:10 to about 10:1 by weight, and wherein the weight percents are based on the total weights of (a)+(b)+(c). Also disclosed is a geotropic propagule coated with the insecticidal composition.
