  • Publication number: 20130239849
    Abstract: The present invention provides novel biolatex conjugate compositions and methods of production and use thereof. The novel biolatex conjugate compositions comprise a biopolymer-additive complex (prepared by co-extruding a biopolymer feedstock, at least one performance-enhancing additive, and at least one plasticizer under shear forces) reacted with a crosslinking agent under shear forces. The biolatex conjugate compositions exhibit enhanced performance properties for coated paper, paperboard, and other applications using extremely low levels of performance-enhancing additives.

  • Publication number: 20130206336
    Abstract: A dried distiller soluble based bioadhesive composition and method for producing the dried distiller soluble based bioadhesives are disclosed, as well as derivatives thereof. The produced dried distillers solubles derives from co-products of corn fermentation facilities, and is advantageously comprised in part of water-soluble proteins. The method for producing the dried distillers solubles generally involves separation and/or introduction of targeted constituents and/or physiochemical treatment to facilitate use as an adhesive. Use of the method and bioadhesive compositions disclosed herein will improve the economics of fermentation by increasing co-product value, reducing plant-wide energy utilization, decreasing waste and emissions, and increasing overall product yield from each bushel of corn consumed.

  • Publication number: 20130206034
    Abstract: A dried distiller soluble based biopolymer, processes for forming the biopolymer, and articles of manufacture thereof. The produced dried distillers solubles derives from co-products of corn fermentation facilities and is comprised in part of water-soluble proteins. A biopolymer consists essentially of dried distillers solubles, and an article of manufacture includes a biopolymer consisting of dried distillers solubles and an optional additive. The process of forming dried distiller solubles involves separating whole stillage into a liquid fraction and a solid fraction, wherein the liquid fraction comprises water soluble proteins in an amount greater than the solid fraction, and wherein the solid fraction has a higher solid content than the liquid fraction. The liquid fraction is sprayed at an elevated temperature to remove at least a portion of moisture in the liquid fraction and form particles and granules of the liquid fraction.

  • Patent number: 7833915
    Abstract: In order to provide grease, oil and wax resistance to a paper substrate, a coating containing a binder, a filler material and calcium carbonate is used. The coating of the invention is essentially free from fluorocarbons, which are considered harmful to human and animal populations, and surfactants and other chemicals which may alter the color of the coated paper. The coated paper has a GE brightness level between approximately 50 and approximately 90, while providing superior grease, oil and wax resistance.
