  • Effect of initial biomass on cellulose hydrolysis by leachate communities

    Batch anaerobic digestions were performed in 160 ml serum vials, cellulose (1% wt) was the sole added carbon source. All reactors were inoculated with a 10% (v/v) leachate inoculum. The concentration of micro-organisms in the leachate inoculums was increased using centrifugation to investigate the effect of initial biomass on hydrolysis performance. The hydrolysis rate constant for digestions ...

  • Commericalizing cellulosic ethanol

    Cellulosic biofuels, produced from nonfood feedstock, are expected to play a critical role in reducing the country's dependence on imported oil. EISA, the Energy Independence and Security Act of 2007, calls for the production of 100 million gallons per year (mgpy) of cellulosic biofuels by 2010, with a longer term goal of 16 billion gallons by 2022.Achieving these goals will not be easy. Several ...

  • The hydrolysis and biogas production of complex cellulosic substrates using three anaerobic biomass sources

    In this study, the ability of various sludges to digest a diverse range of cellulose and cellulose-derived substrates was assessed at different temperatures to elucidate the factors affecting hydrolysis. For this purpose, the biogas production was monitored and the specific biogas activity (SBA) of the sludges was employed to compare the performance of three anaerobic sludges on the degradation ...

  • What is Biomass Pellets Energy

    Biomass pellets energy means the energy made from biomass. What is biomass? Biomass refers to all the organic matters that store energy from photosynthesis. Therefore biomass in most cases means plants instead of animal. What is the chemical composition of biomass? Biomass is carbon based, so it contains ...


  • Liquid fuels from woody biomass

    Although challenges like global climate change and oil depletion will increasingly drive fuel selection, increasing bioenergy use is only one of many possible responses to these problems. Present biomass liquid fuels are almost all derived from food crops, but their potential for further expansion is limited. Any major expansion of biomass liquid fuels will require use of the more abundant ...

  • Post-treatment of anaerobic effluent by ozone and ozone/UV of a kraft cellulose pulp mill

    Pulp and paper mill effluents represent a challenge when treatment technologies are considered, not only to reduce organic matter, but also to reduce the toxicological effects. Although anaerobic treatment has shown promising results, as well as advantages when compared with an aerobic system, this process alone is not sufficient to reduce recalcitrant compounds. Thus, an advanced oxidation ...

  • Overview of biomass and bioenergy sources in northern B.C.

    Ibrahim Karidio identified four groups of biomass sources: cellulosic materials from wood residues, agricultural crops, animal wastes, and municipal and industrial solid wastes. “B.C. has a huge land mass,” Karidio said. Of the total provincial annual allowable cut, 47% comes from the Northern Interior. B.C. generates 31% of Canadian wood residues and 66% of Canadian surplus wood residues. ...

  • A pilot study on suspended activated sludge process augmented with immobilized biomass for simultaneous nitrification and denitrification

    Concurrent nitrification and denitrification (CND) are natural phenomena in the soil environment that can be applied in wastewater treatment for enhanced total nitrogen removal. However, significant renovation is necessary for existing plants to equip them for nutrient removal. At a domestic wastewater treatment plant, we performed a pilot test by installing bioplates with entrapped biomass in a ...

  • EPA Anticipates That Sorghum Based Biofuels Could Qualify For RFS

    EPA announced that renewable fuels produced from sorghum biomass could qualify as cellulosic fuel under the Renewable Fuel Standard (RFS). This is a result of a preliminary analysis of the Greenhouse Gas (GHG) emissions resulting from the growth and transport of biomass sorghum feedstocks that are used to make biofuels. The analysis, which was conducted in response to a petition from the National ...
