  • Patent number: 9580846
    Abstract: A curable aqueous binder composition comprising sheared or extruded cross linked starch particles and a crosslinking agent for use in the formation of composite materials such as mineral, natural organic or synthetic fiber products including mineral fiber insulation, non-woven mats, fiberglass insulation and related glass fiber products as well as wood based products and construction materials. In one application the curable aqueous starch binder composition may be blended with a second non-formaldehyde resin to make fiberglass insulation. In another application the curable aqueous starch binder composition may be mixed into a formaldehyde based resin to make fiberglass roof shingles.
    Type: Grant

  • Publication number: 20120309246
    Abstract: A curable aqueous binder composition includes a dispersion of biopolymer particles, optionally with and an inter-particle crosslinking agent, for use in the formation of composite materials such as mineral, natural organic, or synthetic fiber products, including mineral fiber insulation, non-woven mats, fiberglass insulation and related glass fiber products, and wood based products, and construction materials. In an application of the curable aqueous composition to making fiberglass insulation, the composition may be blended with a second resin which may be a non-formaldehyde resin. In an application of the composition to making fiberglass roofing shingles, the biopolymer particles may be mixed into a formaldehyde based resin during or after the polymerization of the resin.

  • Publication number: 20100311157
    Abstract: Self-sustaining, self-contained systems and methods for producing biofuels and for producing biofuel feedstock from algae. The system is carbon neutral or may be carbon positive, fixing more carbon than it releases to the atmosphere. In various embodiments, the system may be coupled to an existing carbon dioxide producing process to reduce or completely eliminate carbon dioxide output, making the existing system carbon neutral, and providing valuable and tradable carbon credits. The system may also comprise modular tiles comprising a biomass sandwiched between two panels and use a combination of microbes, nutrients, water, and sunlight to generate biological hydrocarbon compounds that can be used in almost any type of engine.
