  • 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.

    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.

  • 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.

  • Technology

    The concern about the effective use of the unused wood biomass from energy security or a perspective of CO2 reduction is increasing. The knowledge corresponding to the multi-energy supply which paired the biological oil manufacture technology from the woody biomass by rapid thermal cracking gasification and biological oil-ization is held. (The level of practical use is reached by joint research with a plant manufacturer.) In addition it owns the knowledge about the circulation and storage corresponding to the properties of biological oils flammability etc.

    Background: Eastern cottonwoods (Populus deltoides) that are suitable for planting in Iowa 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.

  • Technology

    Cellulosic biomass has tremendous potential as a renewable resource for the production of fuels and chemicals. It is especially promising because it is inexpensive and readily available from crop residues and forests. However it is difficult to transform into usable small molecules such as 5-hydroxymethyl-2-furfural (HMF). HMF is acknowledged widely as a key building block for renewable materials and has been highlight by the U.S. Dept. of Energy as a crucial renewable chemical.

  • Technology

    Dr. Steckl and his lab created a platform for an improved electrowetting-based display device that is rollable has the look and feel of paper yet has the potential to deliver books news and even video in bright-light conditions. This device uses specialty paper as the substrate and adds several layers of transparent materials: electrically conducting and insulating layers a hydrophobic layer and water. Individual pixels are defined by a hydrophilic grid that confines small amounts of opaque colored oil.

  • Technology

    Plant biomass represents a vast and renewable source of energy. However harnessing this energy requires breaking down tough lignin and cellulose cell walls. In nature certain microbes can deconstruct biomass into simple sugars by secreting combinations of enzymes. Two organisms that utilize cellulose are Clostridium thermocellum and Trichoderma reesei. Both are well-known and relied upon in the biomass field. Yet research suggests another microorganism of the Streptomyces bacteria group may hold previously unrecognized potential.

  • Technology

    Pratt & Whitney has developed a wood-foam composite framing stud that provides improved insulation over existing wood products. The end product is a 2”X6” stud that has wood sections removed and replaced with insulating foam resulting in a framing member that has the strength of a 2”X4” stud with an R-value close to that of fiberglass. This stud offers additional function in structural support for additional floors and roof nailing surfaces for plywood and sheetrock and provides wall stiffness for wind exposure.

    Several exotic wood borers (Emerald Ash Borer and Asian Longhorn Beetle) potentially threaten the entire community of ash tree species and several other hardwood species (e.g. maples) in North America. The Mountain Pine Beetle a tree-killing bark beetle in western North America is currently impacting 8.4 million acres of conifer forests in Canada and northwestern US. Currently there are few options for insect control that are not chemically based. This new method provides a non-chemical means of insect prevention and control of tree-infesting pests that occur across all habitats.
