Description: In this University of Washington program, Shulin Chen, professor of biological systems engineering at Washington State University, Philip Malte, professor of mechanical engineering at the University of Washington, Renata Bura and Sharon Doty, both professors in the College of Forest Resources at the University of Washington, weigh in on the biomass processing efforts that could change the future. Shulin Chen discusses the technologies and processes for cost-effective use of crops and agricultural residues for chemicals, fuels, biogas, and other value-added products. Renata Bura talks about the bioconversion of lignocellulosic biomass to ethanol. Sharon Doty tells how we can enhance the efficiency of biofuel production using endophytic microorganisms, and Phil Malte explains biofuels combustion.
Abstract: We introduce the ratio of nonflocculent versus total biomass as a criterion for starting cell separation from the medium. This criterion can be applied for the automation of the process regardless of the process dynamics. Its minimum indicates the op...
Abstract: Forschungszentrum Karlsruhe has developed a concept for the utilization of cereal straw and other thin-walled biomass with high ash content. The concept consists of a regional step (drying, chopping, flash-pyrolysis, and mixing) and a central one (pr...
Abstract: In this work an optimized method for the extraction of lutein from microalgae biomass is presented. It has been developed using dry biomass of the lutein-rich microalga Scenedesmus almeriensis. The method comprises three steps, cell disruption, alkal...

Abstract: In this study, biomass pyrolysis process for producing H(2)-rich gas is presented. The whole biomass pyrolysis process is established and simulated based on rigorous thermodynamic model, which includes pyrolysis reactor connecting one oil cracking re...
Abstract: Successful deployment of a bioethanol process depends on the integration of technologies that can be economically commercialized. Pretreatment and fermentation operations of the traditional enzymatic bioethanol-production process constitute the large...
Abstract: The MixAlco process is a patented technology that converts any biodegradable material (e.g., sorted municipal solid waste, sewage sludge, industrial biosludge, manure, agricultural residues, energy crops) into mixed alcohol fuels containing predomina...
Abstract: The increasing demand for thermal and electric energy in many branches of industry and municipal management accounts for a drastic diminishing of natural resources (fossil fuels). Meanwhile, in numerous technical processes, a huge mass of wastes is p...
Abstract: Recently, much attention has been attracted to the use of biomass to produce functional carbonaceous materials from the viewpoint of economic, environmental and societal issues. Among different techniques, the hydrothermal carbonization (HTC) process...
Abstract: Commercial production of intracellular microalgal metabolites requires the following: (1) large-scale monoseptic production of the appropriate microalgal biomass; (2) recovery of the biomass from a relatively dilute broth; (3) extraction of the metab...
Abstract: In the present work an equilibrium model (gas-solid), based on the minimization of the Gibbs energy, has been used in order to estimate the theoretical yield and the equilibrium composition of the reaction products (syngas and char) of biomass thermo...
Abstract: Thermal and chemical conversion processes that convert in energy the sewage sludge, pasty waste and other pre-processed waste are increasingly common, for economic and ecological reasons. Fluidized bed combustion is currently one of the most promisin...
Abstract: Biomass from several fungal species removed thorium from solution in 1M HNO(3), pH 0-1. Thorium uptake was saturable with increasing thorium concentration, although the equilibria did not correspond to a simple ad sorption isotherm. Thorium uptake wa...
Abstract: Due to increasing oil prices and climate change concerns, biofuels have become more important as potential alternative energy sources. It is an open question which kind of biofuels with which yield potentials, characteristic properties and environmen...
Abstract: In this paper, a new wastewater treatment process has been presented to minimize excess biomass production in which both excess sludge digestion and wastewater treatment are conducted simultaneously in the system. The process is modification of conve...
Abstract: A new concept of producing synfuel from biomass using concentrating solar energy as its main energy source is proposed in this paper. The aim of the concept is to obtain an easy to handle fuel with near-zero CO2 emission and reduced land-use requirem...
Abstract: In order to lower the chemical demand (COD) of slops from cane molasses alcohol a treatment of two steps which allows the production of single cell protein of Candida utilis and Paecilomyces variotii has been performed. Its use reduces the treatment ...
Abstract: The inhibitory effect of amino acids on the protease activity of brewer's yeasts has been studied. It is shown that amino acids and peptides formed in the course of autolysis of brewer's yeasts inhibited the rate of this process. To eliminate the inh...
Abstract: This study evaluated the capability of metal biosorption by wasted biomass from a combined anaerobic-anoxic-oxic (A2O)-biofilm process with simultaneous nitrogen and phosphorus removal. Zinc, cadmium and nickel were rapidly adsorbed in 20 min by the ...
