  • Medium-Density Fiberboard (MDF) with Improved Water Resistance

    Type: 
    Product
    Technology:

    Background: Lignocellulose is a component of wood. It is used in a variety of products including medium-density fiberboard (MDF) an engineered wood product formed by gluing lignocellulose fibers under heat pressure and a small amount of resin. Cellulose hemicellulose and lignin are the major polymers that make up lignocellulose and contribute to the material characteristics of MDF. The MDF manufacturing process begins with a pulping procedure that creates a suspension of fibers from wood.

  • MEKO (sustainable charcoal production)

    Type: 
    Product
    Technology:

    A technology involving generation of light by a cuboid metallic box lit with a drum containing wood charcoal generated from burning wood in the cuboid metallic box. It burns out in 12 hours.

  • Enhanced Enzyme Hydrolysis of Biomass

    Type: 
    Product
    Technology:

    Background: The cellulose found in abundance in wood grasses and other plant matter (biomass) is a rich largely untapped sugar source for ethanol production. Cellulose is a polymer of hundreds to thousands of glucose units that is ubiquitous in plant cell walls. The cellulase family of enzymes has been exploited to break cellulose down into glucose for use as a feedstock in bioethanol production. The nature of cellulose in biomass poses a number of challenges to attaining high glucose yield.

  • Trees for Woody Biomass Applications: Improved Aspen Clones

    Type: 
    Product
    Technology:

    Background: Improved aspen clones that produce increased biomass have been developed at Iowa State University. Technology Description: Fast growing trees such as aspen cottonwood and eucalyptus can be grown as so-called short rotation crops and have potential to be used as a source of woody biomass for the production of biofuels such as wood pellets and cellulosic ethanol. In the prime cottonwood growing region which includes eastern Louisiana eastern Arkansas western Mississippi and western Kentucky cottonwoods can grow 12-15 feet per year allowing them to be harvested biennially.

  • Improving Biomass Conversion Efficiency by Modifying Lignin so Plant Cell Walls Are More Digestible and Fermentable

    Type: 
    Product
    Objective:

    Lignocellulosic biomass is a very desirable feedstock for biofuel production. If the fermentation process for lignocellulose could be optimized conversion of this biomass could yield 25 to 50 billion gallons of ethanol or other biofuels per year. However lignocellulose which is composed of lignin cellulose and hemicelluloses is resistant to chemical or enzymatic hydrolysis. This resistance is a key limiting step in the conversion of biomass into fermentable sugars.

  • Ionic Liquid Based Pretreatment of Lignocellulosic Materials for Biofuel Production.

    Type: 
    Product
    Technology:

    North Carolina State University is seeking an industry partner to commercialize a novel method for the ionic liquid based pretreatment of lignocellulosic materials for biofuel production. US Patent No. 8182557 has issued on this technology.Ethanol is gaining in popularity as an alternative fuel and is currently primarily made from the starch in kernels of field corn. However the use of corn as a starting material is a severe limitation since corn is a valuable food source.

  • Compost and Biogas from Organic Waste Materials

    Type: 
    Product

    A researcher at the University of California Davis working in cooperation with an outside collaborator have developed a multi-stage process and system for treating organic waste materials. This process produces a high-quality compost derived from food waste and other organic materials while avoiding the environmental problems of traditional composting methods such as emissions of odors volatile organic compounds and other noxious gases.

  • Unleashing Biomass Sugars Using Bromine Salt

    Type: 
    Product
    Technology:

    Background: Methods to produce bioethanol from cornstarch or sugarcane are inadequate to meet the global demand for renewable fuels. To be sustainable biofuel production should rely on abundant cheap inedible lignocellulose – like switchgrass corn stover wheat straw wood chips and waste paper. However lignocellulose is a complex material made of cellulose wrapped by tough hemicellulose and lignin. For this reason lignocellulose is more difficult than starch to break down and convert (hydrolyze) into fermentable sugars.

  • Utility Promoters for Biomass Feedstock Biotechnology

    Type: 
    Product

    Genetic optimization of biomass is necessary to improve the rates and final yields of sugar release from woody biomass. Areas that would benefit from genetic optimization include growth rate environmental stress tolerance yields of easily fermentable polysaccharides total lignin content lowering biomass recalcitrance to fermentation and wood density. Successful application of biotechnology requires both gene discovery and a proper means for gene expression control.
